Passat (B5) :: Engine Temperature Gauge Reading 190 Normally And Then Suddenly Drop To Almost 0
I have a 2003 Passat and the engine temperature gauge will read 190 normally and then suddenly drop to almost zero, stay there for a while then head back up.
I purchased a temp sensor to replace the old but for the life of me I can seem to locate it. I know it's in the back or rear of the engine somewhere.
BTW, the car has the 1.8 engine.
Prius (Gen 3) Fuel :: MPG Suddenly Dropped
Well I shouldn't say MPG since we canadians use L/100km.

Last year, around Jan/Feb, our temperatures dropped down to about -30F, and I had a weird issue where my brakes literally froze. I couldn't push them at all. I let the car sit for a few minutes, and started slowly pumping the brakes, and eventually got them freed up.
A few months later, the brake line going to the rear popped. I eventually got it replaced. Then a few months later, the front brakes started scraping and squealing, and so I replaced the front pads and calipers about two weeks ago.
Now, the other day I was slowing down to make a turn, and my brakes completely went out. When they did, I heard a pop from up by the engine. I pulled over, lifted the hood, and there was brake fluid covering my hood, abs unit, and a small amount on the engine.
GTI 337/20th Anniversary :: 2005 - RPMs Suddenly Dropped While Driving
About a week ago I noticed my RPMs suddenly dropped while I was driving. a couple days later after driving the highway for about 45 mins, averaging probably 80-90mph, I got into town and I stopped for a car to park. Then it just stalled, I didn't notice a kick back, it's like the car just shut itself off. It took probably 10 attempts to start again. About a mile down the road it did the same thing pulling up to a stop light. I sat through 2 light cycles before it started again.
Got to my destination was there for maybe an hour, when I left the car started fine. Drove for about another hour on back roads when the Rpms started dropping again and I would need to dump the clutch to get them to go back up. Then my screen started beeping telling me to STOP with and oil pressure alert. I ended up driving the car home dumping the clutch whenever the rpms would drop. Once I got home I had my boyfriend take it out and nothing... Of course... A couple days have gone by and it hasnt been as bad but it still drops every now and then, and today after driving home maybe 5 miles it stalled again...
I've plugged it in and my speed sensor is throwing codes, but I don't think that's the entire problem. Whenever my car acts up the EPC light comes on but no check engine light so far. 2005 Jetta GLI 1.8t.....
Lexus RX 2004-09 :: RX330 TPMS Warning Light Came On / Water Temperature Gauge Dropped To Zero
My 2004 RX330 which has gone many years without a problem suddenly has instrument panel gremlins.
I started the car a couple of days ago (it had rained during the day), and the airbag light did not turn off. Then the TPMS warning light came on, the water temperature gauge dropped to zero. The AC controls stopped responding. Since I needed to get home, and the car seemed otherwise fine, I drove home, after a few minutes the transmission "D" drive light went blank and the instrument back-light went to full brightness.
A few minutes later, all the warning lights went off and the back-light went back to normal. The AC controls still seemed to be off. A few minutes later the airbag warning light came back on, followed by the TPMS light and the back-light went to full brightness again. This cycle kept happening all the way home.
The next morning, hoping the problem had been some errant water getting into something, I started the car, opened the driver's door to get something and got back into the car, closing the door. The light showing the door was open stayed on. I put the car into reverse, the doors did not automatically lock as they usually do. I turned off the engine and restarted it, most of the other lights were off, the doors would lock; airbag & TPMS light came back on.
It has stayed that way, except I also get the A/T temperature warning light coming on periodically, and after some cycle it goes off.
I borrowed a car code reader, it does not seem to show any error codes. In reading some other postings it has been suggested that the Brake light switch is the cause, but the brake lights come on/off without any problem.
Golf V R32 :: A/C Just Blow Normal Temperature Air Not Cooling
Today my a/c stopped working, it just blow normal temperature air not cooling, never had a bad experience with it before, I even use it not on the lowest set up, always on 19 Celsius. It was working fine when i arrived at work, 10 minutes later My boss told me to pick something up and when I turned the a/c on it Never worked.... Is this normal?
View 1 RepliesPassat (B5) :: 2000 - Brakes Not Releasing - Power Loss To Re-accelerate Due To Continued Braking?
It's a UK VW Passat year 2000 with 1.8i longitudinal engine layout. Car has ABS
I discovered that the brakes are not releasing quickly after application. Examples where this has been noticed:
When braking and accelerating at the same time to dry brakes after puddles. Noticeable lack of power to re-accelerate when you release the brake pedal, presumably due to continued braking. Noticeable continuation of braking when trailbraking into a corner (ok sometimes I'm a bit of a racer in a family car).
What concerns me is when the snow, ice or heavy rain comes back that I might find sudden instability if the brakes aren't releasing after slowing for a corner or that worse still I'm destined for total brake servo failure.
There are no ABS related error codes although in the ice and snow I did find that the ABS fired until the pedal raised stiff and all 4 wheels just locked up (that was a fun junction crossing).
I have noticed that the drainage ducts in the bulkhead are blocked but I've never had water enter the car so I don't think it's water in the brake servo although this could have happened prior to me owning it I guess.
Working theories:
Due to slave cylinder corrosion and calipers are releasing slowly
Due to brake servo fault - either water ingress of vacuum leak
Prius (2010-12) :: Heater Blow The Constant Temperature Of Air
I have a 2013 Prius 4. I'm not sure if there is a problem or not but the heater just seems to blow the same temperature of air no matter how high I set the temperature. The air feels lukewarm. I was driving 60 miles yesterday with the temperature set at 76. I had on a long sleeve shirt and polar fleece jacket and it never got to where I was really warm. Outside temp was about 50.

Picked up a 2001 Excursion a few weeks ago. Trying to sort out some of its issues. The rear HVAC seems to only blow one temperature... Luke warm. Front A/C and heat work fine. I checked the temp blend actuator and it seems to work fine. The rear expansion valve gets cold and there is condensation that drips from the rear. What else I can check?
View 14 RepliesCaravan/Voyager :: 2002 - No Matter The Temperature Setting AC Blow Very Hot Air
Got a 2002 Grand Voyager (as we name it in Europe), 3,3 AWD, with AC/Heating problems.
No matter the temperature setting, from 15C to 29, it will blow with same very hot air. AC working when setting the temp to LO.
Going from LO to 15 deg C, you'll hear a "clunk", as if a door closes, and the warm air will start to flow through the vents.
Tried all the calibration possibilities known to me (ON+Recirc), and it will end with no faults, but to no good effect on the problem.
What the "ON+AC" mode does? Been in that mode - but do not know what it does, or if I'm supposed to do anything.
I haven't got a clue, other than the "thump" I hear when, possibly, the blend door closes, might be a problem, since I would expect the blend to be more gradually invoked.
Ford A/C :: 2005 Ranger Will Blow Hot Air With Cab Temperature Control Is On Cold Or Hot

View 3 RepliesCavalier :: Air Conditioner Suddenly Blow Warm Or Even Hot Air At Idle
I am in need of the diagnosis of an air conditioner & radiator fan problem on a 2002 Cavalier LS Sport.
The air conditioner blows cold air while the car is moving most of the time. At idle, the air conditioner will suddenly blow warm or even hot air.
At idle with the air conditioner off, the car idles fine. When you turn the a/c on, it runs a bit sluggish. Also, ever 5 seconds you hear what I assume to be the compressor cycle on/off.
After a little research I discovered that this problem could be a faulty radiator fan motor.
Tonight, I pulled the electrical plug to the fan and found that I had voltage to the plug when the engine was running with the air on or off. I then ran wires direct from the battery to the fan and could not get the fan to spin. This obviously tells me that the fan motor must be bad.
My real question is.....should I really have voltage to the fan when the a/c is off and the car is just started? I thought the fan should only turn on when the engine got warm with the a/c off. I started the car and pulled it in to the garage and then shut it off before I did my testing so I don't think that would classify as getting the engine warm.
I am now wondering if the voltage was always present even with the AC button off because I may have had the fan in the recirculate mode. The AC light is lit in this mode even when the AC button is off.
Honda - Accord :: Heater Suddenly Blow Ice Cold Air And Odd Shaking Routine
2005 Honda Accord.
Problem 1: Now that is is finally getting below freezing and I am having to use my heat, and I have noticed that it will all of a sudden blow ice cold air. It does not matter if I am idle / accelerating / decelerating. I must provide a disclaimer... I have not had to use the heat in the car since I purchased it Certified Used from the dealer in South Florida. After moving back to where it actually gets cold I find this issue. I had my trusty mechanic look at it and he flushed the heater core. That is problem 1.
Problem 2: For about 6 months now my car has been doing this odd shaking routine. It happens probably every time I am out driving. When it starts to shake, I can prevent it from dying by revving the engine. It does not matter if I have just started the car, am sitting at idle or if I am driving down the road. No check engine light or malfunction indicator light has come on the entire time. It feels like the car just runs hard, not nice and smooth like it used to. I have brought my car in to the trusty mechanic three times now and he can not find any problems. I did notice this morning that while sitting idle at the stop light, my car had its little epileptic shake and then stopped and the RPM's dropped to 500.
Later when I arrived at my destination, while sitting at idle before getting out of the car, the RPM's were at 2000. I have routinely put in fuel injector cleaner additive when I fill up with gas... maybe once a month. I usually fill up with regular gas, but will occasionally fill up with premium. This whole situation is blowing my mind!
IS F (2008-2014) :: Oil Temperature Start Rising Suddenly
Fully stock 2011 IS F. This past Friday I had the low engine oil level light come on. I immediately took it to the Lexus dealer Saturday morning. The tech said the engine was 2 quarts low on oil. The dealership offered to top it off for free since my interval had at least another 1500 miles left before a complete oil change. I opted to conduct a complete oil change instead and gladly paid for their services.
I even entered the service bay since the regular tech who works on my F wasn't there that day. I ensured the tech topped off the oil correctly and asked if there was any harm to the engine? He said absolutely not, the sensor did its job! No harm no foul...everything was good until last night...
I daily drive my F and you can say I drive my F hard. It was between 10pm and 11pm the ambient temperature couldn't have been past the lower to mid 80's. When all of a sudden my oil temperature started rising! And rising fast! I immediately let off the gas and began to worry. This has never happened! Not even on my previous F, which was driven in the same manner, and with straight pipes. I've had this F since January but I'm getting the feeling something is wrong and it's killing the joy of driving it freely.
I was in F mode and paddle shifting like I always do every night. I also could have sworn I lost power. I did a search and only ran into the F that was taken to the track, but the thread didn't really answer anything for me. Other than freak me out even more as one owner mentioned his F never goes past 3 bars! After a track session! I'm sure it was for 2008-2010 F as the gauges are different. I drove it conservatively this morning and opened her up a little and everything was fine. I wasn't in F Mode just sport and auto.
Toyota :: 1987 - Fuel And Temperature Gauge Won't Working Suddenly
I borrowed a friend's small Toyota truck for a few days of easy chores, and made a point to check the fuel at the beginning: the gauge showed 3/4 full. Four days and only 25 miles later, when I got in to return it, I noticed the fuel gauge was not working, I'm certain there's no fuel leak, I would have noticed that: the truck had been parked on my property the entire time, driven only a few hundred feet from one spot to another moving firewood around, so I would have smelled the gas if there was a leak.
When I added a couple gallons of fuel, the gauge didn't budge. Once on the road, I realized that the engine temperature gauge was also dead - no change on the gauge after 10 miles. So I have two non-functioning gauges which failed on my watch. This may not be directly my fault, but as my friend is kind enough to lend the truck whenever I need it, my contribution is to provide maintenance.
Is there anything in common between the two gauges which would explain the synchronized failure? Or is this total coincidence? This one is outside my experience, so don't know where to start. It's a 4 cylinder, 5 speed manual, base model truck, about 150k, generally runs just fine. There are no other gauges, and I don't recall what warning lights there might be, but I didn't see any after I realized there was a problem. Would the whole instrument cluster die at once, or could this be something like a bad ground for the cluster? I don't mind investing effort into tracking down and solving a problem, but if it needs a new cluster, that will cost more than I'd like to contribute, yet the problem occurred while I was using the truck (gently). My total use of this truck for all the times I've borrowed it is certainly less than 300 miles, so I'm reluctant to fund the entire repair if this is something that just comes with age.
Ford Excursion :: Engine Suddenly Quit / Temperature And Oil Light Came On
I was going up a little grade a couple days ago and the engine suddenly quit, the temperature and oil light came on, the heat gauge buried on hot, and it threw a code. I pulled over and it was still idling so I made a U-turn but it was in limp mode and would only go about 10 MPH, so I made it home and put water in it so it's good now but it still says service engine soon. What is the code going to say and am going to have to pay to get rid of it. (the light). I have a new cap coming.
View 14 RepliesFord Super Duty (1999-2016) :: 2000 F250 - A/C Wouldn't Blow Cold Suddenly
My 2000 F250 SD 5.4 AWD's A/C wouldn't blow cold suddenly the other day. I confirmed the A/C relay (engine compartment, 3rd down from firewall)was "clicking" but compressor clutch was obviously not engaging with dash switch on Max A/C and engine running. When I take of the 2 wire connector to compressor to see if it is getting power, the truck won't start..if I disconnect the A/C compressor plug while running, the engine similarly quits. I have never had another vehicle do this on me before..I could unplug the compressor on my Jeep GC, for instance, measure 12+ volts with A/C ON w/car running and no problem with Jeep engine turning off.
I have searched for A/C wiring schematic w/o success. I checked every fuse in cab/engine for continuity since I don't know which ones might deal with A/C..jumped hi/lo pressure switch connectors with engine running/A/C ON w/o compressor clutch engaging. Clutch turns easily, have banged it a few times, and air gap looks good. More bizarrerly, I hooked the compressor to a 12V/ground via its 2 male prongs and didn't get the clutch to engage.
Sonata I45 (LF 2015+) :: Temperature Light Suddenly Came On - Broken Serpentine Belt
I am driving a 2015 Sonata with 20,000km (13,000 miles) and the temperature light suddenly came on. I stopped and checked things and could find nothing wrong (oil and coolant OK). I was close to home (less than 1 mile) so drove until light came on again then stopped until it cooled a bit and then home. I thought it must have been the sensor because engine definitely did not appear to be hot.
Once in the garage, I inspected things a little closer and noticed a destroyed serpentine belt--ripped to shreds. Not sure what caused it, but that was the problem. I was afraid of a coolant leak which would have been more serious.
Passat (B6) :: 3.6 Fuel Economy Dropped
I have the 3.6 and it has been great on fuel economy up until last week. I was averaging about 26mpg and getting near 20 mpg around town. Now my fuel economy has dropped to 15mpg city and 25mpg highway putting the overall MPG down to around 20. What happened? Did I get a bad tank of fuel or is it time for new spark plugs? The car has 34k on it; and when I checked the plugs at 28k they looked like new and gapped to within .002 of the spec.
