did you ever change your fpr? On an old gti of mine I did that...it was a bad idea

returnless fuel systems on b6

na never changed fpr i ran vagcomp on my car and i got a couple codes one for bad temp sensor thats y the temp gauge didnt work changed that now gauge works had another code for rear o2 sensor changed that and then i changed the n75 valve cause of limpmood...what eles can make it go into limp mood i was even getting on it when it went into limp mood after the n75 change

[ziggituning]

It could be the N75 from ecs, I have seen it to throw codes on B6 before, try a stock N75 (that you know is working), this may be the issue, and of course verify for vac leaks etc.

[Greek Yayo]

well the valve is brand new it ha maybe 6 hrs in the car...and ur saying vacum leaks can cause limp mood to turn on?

[Greek Yayo]

could vacuum or boost leaks be a cause of limp mode?

got Vag?

my car takes about 30 miles to get used to any intake/boost related modification... When I replaced my N75 (faulty) to a J valve, my car was only boosting 4psi for the first week, then it went back to 8. After my FMIC install... same deal. give it a day, or try removing the battery (make sure you know your radio code)

[Greek Yayo]

i dont know my radio code and audi askin 80 bucks to get it... damm

[B6driver]

some radios do it, some don't. but if you want to chance it go ahead. My radio has never asked me for the code even after being unplugged for a couple weeks.

my only other real suggestion is to check for leaks and find a Vag com user in your area... or you can get an ebay one which is good for reading/clearing codes
