Golf IV / Jetta IV :: Noticed Water Running Down Driver Side
As I was loading a bag into the back of my GTI, I noticed water running down the drivers side. It seems to be coming out of where the driver's side back seat belt holder is. It's leaking down into the little compartment as well. Don't know the extent of the damage yet as I haven't had any time to look, The interior ceiling of the car is dry. Leaking into the side compartment as well...

Recently returned from trip from Austin Tx to Monroe LA. Gas mileage decreased from about 43.3 MPG to 38.5 MPG. A little annoyed by this but I guess I can attribute this to the increased weight in the vehicle. Still taking care in for other thing. Maintenance needed light came on & I assume it may be for a 15,000 mi checkup since it is nearing that mark.
View 3 RepliesGolf IV / Jetta IV :: Noticed A Pool Of PS Fluid On Ground / Power Steering Leak
Well my car is crapping out lately,
I put a new steering rack in my mk4 1.8t jetta about a week before I parked it for winter. I went out to the garage yesterday and noticed a pool of PS fluid on the ground, I located one very small leak from the bottom banjo bolt on the rack (needs new crush washers, Was in a rush and didn't have time to pick new ones up :bang head: ).
But the part that confuses me is there is a puddle on/under the passenger side subframe, the rack boot appears to be dry, and I don't believe the new rack is faulty, they are supposed to be all tested and approved before reaching the buyer. and when I turn the car on I can't see a leak anywhere even with the wheel off and a decent view of the rack.
Prius (2010-12) Fuel :: Hot Weather Mileage Decrease
I don't have a lot of data yet, but the last couple of times we had temps over 80F, my mileage took a significant hit - about as bad as when temps are below 20F (more than 10%)... Shutting off the A/C doesn't change things much...

The stock 265/75/16 tires need to be replaced and I was considering swapping 285's on the stock wheels. Will I notice an increase in fuel consumption? I realize that calculating mpg will need to be adjusted due to larger tires since the speedometer will be slightly off.

My 03 2.7 has suddenly lost around 4 MPG in city driving. Haven't taken it out on the highway to know where that is at. Used to get around 20/21 and now I'm around 16/17. Mileage is at 97k now and has new spark plugs and brakes done recently. I know the brakes are not dragging. All the fluids are fairly new and the car drives the same as before, I can't feel a difference in performance. Just lower gas mileage. I haven't changed out the T-stat yet, but the temp gauge in car reads the same as always. I checked the car with a code checker and there are no pending codes. I know this is the age where the oxygen sensors could start to go bad and have never replaced them.

I bought a 2012 Prius new and averaged just under 53 miles per gallon for the first 15,000 miles regularly. I have a long commute so my driving mix of city/highway is pretty consistent. When starting the car one morning there was a fairly loud series of clicking sounds from the engine compartment, which then stopped. From that point forward the mileage has dropped to just under 50 mpg. Same driving habits. I am bringing the car if for it's 20,000 mile check up shortly. Any ideas if something happened to the battery I should ask about? It is still under warranty.
View 4 RepliesFord - Taurus :: 2005 - Can Cleaning A Mass Air Flow Decrease Mileage?
I had a check engine light on my 2005 Ford Taurus and my mechanic suggested cleaning the mass air flow. Afterwards, the light was off and the car seemed to drive fine ( it was driving fine even with the check engine light on) But my mileage dropped drastically. On the freeway it went all the way down to 10mpg! Right now around town it is fluctuating a bit, but around 14mpg. Should I have the mechanic check for a loose wire or something not connected properly? Or just replace the darn mass air flow?

View 5 RepliesGolf IV / Jetta IV :: 2000 - Won't Start At Cold / Poor Fuel Mileage
I own a 2000 Jetta VR6 5 speed. Car has over 300,xxxkm on it, with documented maintenance including chains within the past 12k. Car has intake, 2.5" resonated exhaust, stock software.
I have recently noticed that the car has a cold start issue. Its winter here in Canada, so in the morning when i go to start the car and let it warm up for a couple minutes, the idle is choppy at first and then evens out at around 900-1k rpm. If i try to blip the throttle, or even hold it (half way or WOT) the car just wants to bog out, EXTREMELY rough idle. It will eventually, after about 2 mins of idling, go away and i can drive.
I have absolutely no issue with allowing the car to idle for a few mins to warm up, but i know for a fact that whether a car is cold or not, it should be able to rev freely.
I also have horrible fuel milage. I use 91 octane, and average about 250-300km per tank. 70% city 30% hwy driving.
The following parts have been replaced in the past 1200 to try and resolve the issue
OE Mass air flow sensor
OE spark plugs
BREMI wires
OE Bosch front O2 sensor
I have scanned the car several times, which led me to change the parts i did. Only had a CEL once and it was for the front O2 sensor which i just replaced. Any other codes were for random multiple and a cat efficiency fault. Again those were fault found off a GFF test done at VW, they were not enough to trigger a CEL, but i still changed the parts.
Golf/GTI VI :: Noticed A Series Of Misfires
Yesterday it was the coldest day my car has ever experienced at -27*C or -16F. I only live about 10 minutes from work in stop and go traffic so the car barely reached operating temp as I was arriving to work.
After about 10 hours, I went outside at the end of the day, the temps had warmed slightly and I started the car and let it idle for about 1 minute before driving off. After about 45 seconds I got a series of what seemed to be misfires. The EPC light flashed but eventually turned off, and where the odometer normally appears there was an exclamation point next to a symbol that looked like cruise had been activated. A message appeared in the MFD to the effect of "malfunction - bring car for service"
I reved the car slightly a few times-all seemed good- and left. All was good. Stopped the car a few blocks after and restarted and the warning symbol was gone and all was back to normal.
Today has been warmer and there have been no issues with it.

My car was just in the shop for the 30K service and the tech noticed quite a bit of oil leaking from the gasket between the CTS pcv system and the engine. He said that because the catch can lacks the ability to release the pressure coming from the engine, it started to eat at the gasket and it now leaks... he recommended that I take the catch can off. I thought the system vented pressure into the intake...

Dealership put some dye in the oil last week and they're checking it today but they said it seems like it's getting flung around when it hits the axles. Waiting on a loaner because they want to hold it and let it run to see what happens. Whenever I look under it in my garage I see oil buildup on the oil pans passenger side and see a drop about the size of a dime.
View 3 RepliesGolf V R32 :: Noticed Slight Non - Metallic Vibration Noise
I know it's stupid but rattles and vibrations in an otherwise quiet car drive me absolutely crazy.
So, driving I have noticed this slight non-metallic vibration type noise. It seemed to come and go. So I emptied the car thinking it might be something I was carrying around. No such luck. Turned off the climate control, still there. I had the better half drive while I searched. I could never really see anything but thought it sounded like it might be either in the dash or around the floor area. Totally frustrated I unbuckle my seatbelt and crawl into the passenger floor head first. Nothing on the passenger side. I glance over to the Driver side footwell and notice the slightest vibration from a panel that covers the steering shaft as it goes through the firewall right behind the pedals. Aha! A plastic panel being held in place by 2 plastic type screws that are both loose. i tighten them down with a straight screw driver when I get home and silence! The rattle goes away. You might look at yours as well. I think this might apply to all Mk5 cars. Finding/Fixing a rattle like this for me is like finding money.
Golf VI R :: Significant MPG Decrease After Neuspeed Intake Install
My MPG has fallen ~ 35% since the intake was installed. Barely did 20mpg driving at 75mph from Vegas to LA and now averaging about 17mpg on the next tank. What should I be looking for? I'm stage 1 APR (was before the Neuspeed as well) stage 1.
View 11 RepliesGolf V R32 :: Squeaking Noise From Passenger Side Increase And Decrease With Engine RPM
Symptoms : You will hear a squeaking noise from the passenger side of the car. It will increase and decrease with engine RPM, and apparently can be heard from inside the car as well. This noise is from the tensioner bearings failing...which, if gone untreated, will then cause the serpentine belt to fail.
If the belt fails, it seems that the battery light will come on, followed by engine coolant temperature spike (overheat).
Bad tensioner sound:
Confirmed failure shortly after this sound:
Jetta - Volkswagen :: 2004 - Reoccurring Misfire / Dropped Mileage
Recently (5 weeks ago), my 2004 Jetta misfired, which caused the car to shake very noticeably, especially at lower speeds or while idling. The misfire was accompanied by the smell of fuel on the driver side and triggered the check engine light to flash. I took it to the shop (a VW dealer). They ran diagnostics, found it signaled a misfire (but no other major issues/sensors) and told me it was due to the spark plugs/wires. I was dubious, as they were not too old, but I allowed them to replace them anyway, as they assured me this would fix the problem.
Just this week, however, another misfire occurred, also accompanied by the smell of fuel and shaking. This time, the check engine light remained on (constant) for 2 days, and on the third day, it was off. I brought it back to the same shop to try to figure out the real cause of the misfire, which obviously was not the previous spark plugs. My city gas mileage has also decreased over the past month - down to about 20-21 mpg from 23-24. What could be causing such a reoccurring misfire without signaling an issue with a sensor or other part?
