Hi All, Owned my Gti for about a 6 weeks now, loving it apart:
At 70 mph its doing 4000 revs, it has had its gearbox changed may 2008, it obviously ruins the fuel economy and the noise.......
Id be grateful if anyone has an idea of how i can fix this or what to do about it, cheers (Y)

I assume thats 4000RPM@7-MPH in 5th?
It should be about 4000RPM@85... it has been known for people to end up with the wrong ratio gearbox fitted....

Looks like you are going to have to see if you can find another box from a GTI!
Before you fit it, check the gear ratios just to make sure it is "as it should be"!
This has to be the main reason why I suggest people get their own box rebuilt rather than getting a recon one from an unknown car.....there are several identical looking boxes with totally different ratios...

Yep, sounds like incorrect ratios for sure...

Aii i had mine rebuilt, aswell as having the correct ratios, you still have the GENUINE box in there aswell

Should be around just over 3000 rpm. My new box does around 2700 rpm. Only got 270 miles before the light came on, because I'm having to stay in the lower gears for town driving

OR...you enjoy the shorter ratio! so a faster 0-60!
