Volkswagen GTI Engine Problems

Thanks for the reply. That makes sense. I guess the issue is really more about power loss (usually when the car is still "cold") between 1st and 2nd in the automatic mode. It's akin to the feeling of letting of the gas and then getting back on it -- without ever reducing power. I might need a dealer visit.

"I guess the issue is really more about power loss"

Turbo lag isn't a loss of power, rather it is just a delay in gaining power. It takes a little time for the turbo to spool up and force the compressed air back into the engine. The reason why you feel turbo lag between 1st and 2nd gears is because the engine has not produced enough exhaust for the turbo charger to have an impact.

Has anyone "chipped" their '07-'08 GTI in an effort to increase performance?

A couple of questions:

Does this void your warranty?

Do you have to make any other adjustments to the car to be able to handle the increased HP?

Did you do it yourself and how much did it cost?

OK, that was 4 questions.

I registered just to reply to this question. I have 2007 GTI with dsg. For the first year i had the same problem you have. Took it to the dealer several times but was told everything was normal. It wasn't turbo lag but a very slight stutter. I thought i would just have to live with it. I recently had a check engine light come on that was related to a bad fuel pressure sensor. After the fix and remapping, the stutter is gone. I'm a happy driver now, just sorry it took a year to get right. Have the dealer check that sensor. Could be it. Good luck. Let us know if that was it

#81 of 82 Is ever ok to mix gas? by buffy22

I have a '06 GTI which, of course, takes premium gas. Is it ever ok to
add the less expensive gas? I imagine it might hurt the engine?

It will not hurt anything mechanical; your engine knows how to effectivly "de-tune" itself to accomodate the lower detonation resistance of the lower grade of gasoline. The only things you'll "hurt" are the acceleration and fuel economy of your car and your wallet (due to the lower fuel economy).
