Golf IV / Jetta IV :: On Stock Valve Car Would Get Random Boost Surges
I have a 05 GLI and I noticed that on the stock "E" valve my car would get random boost surges. I would barely tap the gas and the boost would build up to 8-10 PSI so I bought the J valve thinking it would solve the problem and just installed it today. I took it around the block and really liked how the power delivery became smoother and the car didn't have any boost surging issues. When I decided to put my foot down I noticed my car was only getting 11-12 PSI throughout the whole power band. Before on the E valve I was getting 16-17 PSI. My car's running a Unitronic stage 2 tune btw. I know upgrading to the "J" valve is a hit or miss but I think it's kind of odd that the car drives smoother but isn't running as much boost. I like how it feels for daily driving but something doesn't feel right.
View 2 RepliesGolf V R32 :: Downshifting Very Hard When Coming To A Slow Stop
I picked up an '08 R32 about two months ago and was having issues with the DSG and the dealership determined it was an issue with the mechatronic unit so they swapped it. That made a huge difference, but the downshifting is still very hard when coming to a slow stop (to the point where the car jumps), especially from 2nd to 1st gear. About half the time when I back out of a parking spot, then put the car in drive and start to give it gas, the car doesn't move for a few seconds as the RPM's build, then it slams into gear.
This all happens in drive (D). I haven't even used the other modes to know if it's happening there too. The dealership says they don't see any issues with it and there are no error codes and that there is nothing wrong with the car, but this is by far the worst transmission I've ever had in any car I've ever owned. I find it hard to believe that VW and Audi would put this in their higher end cars, so I can only assume there is something wrong with mine.
Toyota - Tacoma :: 1999 - Surges Forward At Random Intervals While Idling
I have a 1999 toyota tacoma 70,000/mi. While idling, at random intervals, truck surges forward. Have to stay on the brake. Cannot drive in winter. Took to Toyota dealer and other mechanics... described problem and that A/C seems to be on all the time. No one has been able to fix. My brother disconnected the A/C and surging has stopped, but I need a better fix that will allow my using AC.
View 4 RepliesAccent LC (2000-05) :: Thump When Downshifting And Come To A Stop
My nice little 2002 GL 1.6 has 160K+ on it. Lately, when I come to a stop, I get a thump when she downshifts. I don't know which gear exactly, but it happens when the car reaches 10 MPH and below, so maybe when it goes into first? It is just as the car stops, it seems.
More recently, it seems as if when I get just about stopped, it feels as if she completely disengages from drive and goes into neutral. But it doesn't actually do that, she is fine when I take off. She upshifts just fine, it's just that last little bit when coming to a stop.
I have never had the transmission messed with very much, but I know it was serviced a few years ago. I did add a little fluid a few weeks ago after I checked it, and I was very careful to purchase the exact correct fluid.
Tiguan :: No Downshifting When Going Downhill Or Coming To A Stop
We have a 2010 Tiguan SEL 4 motion automatic and today it just died after i pulled out of parking spot. the only light on the dash was the battery light. I restarted once i put it in neutral. When driving home my wife and i notice it was not downshifting when going down hill or when coming to a stop. This is not the usual behavior. It also seemed like it was costing in neutral when i was not in the throttle. I dropped it off at my usual dealer and hopefully they can duplicate it.
I am wondering if the battery or alternator is bad and the transmission computer was not getting good voltage and that made it act funny.
Ford Transmission :: C6 Not Downshifting Until Complete Stop
My freshly rebuilt C6 with Transgo shift kit and Hughes 2500 stall converter won't downshift until I'm nearly at a dead stop. My Cruisomatic did the same thing in stock form. I roll up to an intersection and the light is green. I slow way down to negotiate the turn. I then throttle when headed straight and the tranny is still in Drive. It does the same thing when slowing way down for speed bumps. Could the shift kit or stall converter affect downshifts?

View 3 RepliesAccent LC (2000-05) :: When Coming To A Stop Sign Car Not Downshifting
So on my way home today from work I came to a stop sign and noticed my car (2001 Hyundai Accent, 1.6L Automatic) didn't downshift while coming to the stop. So I stopped and hit the gas, and the car didn't move, it only revved. So I put it in park and it banged into park, then I put it in drive and it banged into drive. Then while driving, it will only shift when you let off the gas and like 5 seconds later after you let off the gas it shifts really really hard into third I believe. And in addition, there is no reverse now! I put it in reverse and nothing, even when I hit the gas it goes nowhere.
View 5 RepliesFord Transmission :: C6 Downshifting Early When Coasting To A Stop
I have a 77 F250 4X4, 400, C6. Upshifts and downshifts are working normally, except under light load and minimal throttle the tranny downshifts to 2nd at any speed under 40 mph. I've never had an automatic do this before. I checked the kickdown linkage is pulled up so it's doesn't seem to be in kickdown position always, no vacuum leaks to the modulator. I confess to be more of a manual trans guy so my knowledge is autos is limited.
View 2 RepliesFord F-150 (2009-2014) :: Downshifting When Rolling Up To A Stop Sign
Well I have 8000 miles on my 12 Eco now and it has been the best vehicle I have ever owned but it has always shifted rough, Mainly into 3rd gear but you could always feel it downshifting when rolling up to a stop sign also, I just assumed it was the way it was suppose to be. This morning I was driving it and noticed it was shifting very nice and smooth, no downshift braking or the other little issues.
I also noticed the the select shift was turned off (the numbers on the dash 1-6) if you push the + button on the shifter you can turn them off, I have had it turned on since I bought the truck because I kind of liked the display but anyway with the select shift turned off the transmission shifts very nice, I turned it back on and the rough shifting returned, Try it on yours to see if it changes.
Engines - Lights - Suzuki - Transmissions - Aerio :: CEL On While Driving And Car Stop Downshifting From 3rd Gear
I have a 2005 Suzuki Aerio with an automatic transmission. Occasionally, maybe once every month or two, the check engine light will come on while I am driving and the car will immediately stop down-shifting from 3rd gear. The car otherwise seems to run fine but I end up having to manually shift to get to wherever I am going. Then on my next trip, the transmission will shift fine but the check engine light will stay on for an additional trip or two and then go off. What is going on. By the time I get to it the light is off again and the car seems to function fine.
View 4 RepliesGolf IV / Jetta IV :: 2003 GLI 2.8L 24v VR6 - Random Electrical System Reset / Power Failure
2003 Jetta GLI 2.8L 24v VR6 .... Last night I went to a friends house, everything was normal on the way there, probably 35-40 degrees out. When I got to his house and shut off the car and pulled the key out the power died (clock/trip meter reset) and the alarm started going off. It has done this before once or twice but I could never figure out what it was and it was never really an issue except for the clock resetting.
Jets won, went to leave and the car wouldn't start. It was raining gently at the time but the car has weathered worse. I replaced the battery ~2-4 months ago so it should definitely still be good. Jumped with my friend's car, started on the first try. I let it sit for a bit then we were on our way.
1/4 mile away in the middle of an intersection the car died, power steering, everything, and I had to drift to the other side of the road. The person across the street from me was a cop and it was 12:30 in the morning but he was gone before my car died. I have been driving 5/6 speeds all my life and I know I didn't cause the stall out. The dash lights flickered and dimmed. I shut everything off and then gave it a try and the car started right up. Revved the engine a few times, reverse and drove away. It was fine the rest of the way home.
The battery connections are tight. The car has started every single time up until now with the new battery. My old battery did leak some acid on the copper connectors and into the main positive power cable but I neutralized all of it and cleaned it off and it looked fine except for some pitting on the outside of the terminal clamp. The car is mostly stock except for the exhaust but that was years ago.
Current Battery Voltage: 12.37 ... I just started the car for the first time this morning and it started perfectly. started @ ~1200 and then settled down to ~800rpm after a bit, it usually does this when its cold out. No codes have been thrown.

View 9 RepliesGolf IV / Jetta IV :: Power Loss At Random Times While Driving Or Idling / Headlights Flickering
I've been experiencing power loss at random times while driving, idling, With almost always flickering headlights on my mkiv 1.8t gti. Also on what always seems like the exact same spot on the freeway I'm losing all power to the wheels and it feels as if my plugs aren't firing for about 10 seconds Which causes me to bog down. At which point I down shift and play the throttle until my motor then begins running normally again.
I've semi recently replaced my battery and terminals, due to corroded terminals and worn out battery. Is is possible a ecu reset could solve this problem?
Also when the power surges during driving my traction control and hand-brake lights on the tachometer will flash and the car will beep three or four times (same as when the hand-brake on beep).

View 2 RepliesGolf IV R32 :: Uneven Idle / Slight Surges Under Acceleration
OEM plus. 93k. Um tune. Evoms intake.
Did the plugs and coil packs, fuel filter, cleaned throttle body (Did a vagcom alignment) as well as some other insignificant maintance.
Car ran fine for weeks after, but recently it has started to bounce around randomly at idle. Like 650rpm(normal) for a few seconds. Then it will Slowly climb to 800rpms, hold there for a few seconds. Then back down to 650ish for a few seconds, then back up to 800 for a few seconds. And so on. It's very subtle and very random. Then sometimes when accelerating, I can feel it in the gas peddle. Like a slight pulsing power loss. Very slight and of a similar rhythm to the idle issue.
I do have a check engine light for Load Calculation cross check-p1143-001 upper limit exceeded. But that has been a battle I have been fighting for a year or so, and I think that is some kind of vacuum leak, but this rpm issue just started a few weeks ago. The only thing I was thinking so far is that when I was doing the plugs and coil packs, I noticed that there was a slight bit of what looked like dielectric grease on each coil pack already from the factory. So I didn't put any more in the coil packs sleeve part that fits over the plug. So was that a mistake? And if it was a mistake would this be a symptom of that?
Civic - Honda :: 2004 - Random Overheating In Stop And Go Traffic
I drive a 2004 Honda Civic. About a month ago, my car started to overheat. The next day, I took it into the shop,and they said the thermostat was sticking,and I had a small leak in the radiator. I got a new thermostat, radiator (they did not have anyone to repair), and flushed the system.
A few days later, the car started to overheat again, and quickly went down. We thought it was a fluke. A few days later, it did the same thing and we took it back to the shop. They said nothing was wrong and let the car run with the radiator cap off for a while in case there was a bubble. Since then, it has has started to overheat a few more times. So the, problem is not all the time, just every so often. Several parts have already been replaced, as noted.
What we have found in common is that each time it starts to overheat, we are in stop and go traffic. It has always been hot outside too (but it is summer). When we begin to move at a regular pace, the car temp goes down. I live in a city, so it is impossible not to get in stop and go traffic on a regular basis. Not everytime we are in stop and go traffic it does this, but since the repairs, it has never overheated while moving at a regular pace.
Golf/GTI VII :: DSG Noise When Downshifting Through 1 / 2 And 3
I've been noticing this noise recently and I'm wondering if it's normal with the DSG. Almost a clicking that I can hear, mostly when downshifting through 1, 2 and 3. Not sure if I simply can't hear it above this due to road noise though. Threw the GoPro on a suction mount and got a bunch of clips from a short drive around the neighborhood.
