#27 of 31 Re: 2007 GTI Check Engine Light and Fuel Issues. [chuck719] by jitteryjoe_246 Sep 06, 2007 (10:10 am)
Replying to: chuck719 (Sep 04, 2007 5:30 am) Sounds like a problem I just got fixed on my '06 GTI (new model style).   Way back in February my CEL came on so I brought it to the dealer a week or so later. They ran tests on it for 4 hours at which point I got sick of waiting. They said it was a problem with my 'low side fuel pressure was reading too high'.   After getting the car back I drove it just fine for the next six months (good performance, good mileage, check engine light still on). During my next scheduled maintenance in August I had them take another look at it. At first they thought it needed a new fuel filter, but then they thought it was the low fuel pressure valve. They apparently replaced both of those parts but it was still giving them problems. They then replaced the high pressure fuel valve and that did the trick.   The car was in the shop a full week while they did the work and waited for parts. From the way it sounds volkswagen fuel systems are moronically complex. Not mad at the dealership, but I would like to smack whatever german engineer who dreampt that design up! Car seems fine now.   The repair was totally under warranty with no cost to me. I had a free rental (a pos nissan versa) that I abused the hell out of for a week. That little skateboards tires would scream at the drop of a hat!
#28 of 31 Tiguan; Anyone interested? by feliciatwo Nov 15, 2007 (12:20 pm)
I had looked forward to the Clean Diesel Tiguan ...believe it or not I won't buy it now because the second row seat doesn't fold flat; I need all the Utility I can get out of a small package.

Replying to: chuck719 (Sep 04, 2007 5:30 am) I promise you that the problem is your MAF Sensor. It is dirty. The dealers all know this and they play it to death. It is a scam. They use it to force you to bring the car into the shop. Once there you're car is a prisoner. Buy a can of MAF SEnsor cleaner, remove the sensor, give it 5 or 6 blasts, replace it and your good for 5000 miles. Trust me, I went through the exact same thing and even ended trading in our 07 for another 07 manual tranny thinking it was the DSG. When I found out what the cause was I cried because we loved our first VW. Dealers are scum!

Replying to: rmfolk (Apr 05, 2007 1:49 pm) What VW/Audi will try to tell you is that the 2.0T will achieve less mileage on regualr gas which makes sense to me. However, it isn't true. I run my GTI on regular with spirited highway/city driving and achieve 24-25 mpg which is the same if I use even the best high-test, such as shell V-power. I will tell you this: They weren;t lying when they said the computer compensates for the lower fuel and restricts power... The loss in power is VERY noticable. You will notice gradually as you pass in 6th gear on the highway and everytime you let the clutch out in first gear, By now means is the car slow, it just doesn't feel as quick and it really isn't. Weigh out the savings verses lack of fun for yourself. I like SAVINGS!
