golf mk4 loss of power... help please

im going to try and get my car in at this place with the vag com software so ill search for this post and let you know the codes that are found when i find out.
regards andy tanner

i bought and fitted a maf but it has hardly made a difference although its probably a good idea to have a new one at 76k anyhow. this weekend i want to check all the hoses and make sure that n75 valve moves etc. should i disconnect the battery when i fit something like the maf or is that a waste of time.

my next thing after that is to find someone near grimsby that wouldnt mind helping me with vag-com software.
if any one could offer any assistance id be most gratful as ive had the car since march and its never run right

i found a place in grimsby where i live that has the vag com software. they come under one of the dealerships on the superchip website so they should be more helpful. iv got it booked in for next friday so ill post the results asap.

I've heard a lot of the MAFs are faulty straight out of the box, so don't go assuming the MAF isn't staill at fault.

Ther was once a very wise man called Crasher who had three seperate MAFs fail one after an other.

Good luck

thanks for the reply but i have a feeling it is something more along the lines of a leak. but definatly a good point, we cant asume that just because its new its ok

had a diagnostic. i havent got it here but vag com stated over boost im sure the number was 17695. the garage said that it sounded like the vanes were sticking so i really dont know what to do. what could cause an over boost.
it will cost me 250 to let them get the turbo off and put it back if i need a new one, i have to do this anyway as you cant see the garret number on it if i have to order a turbo.
i must admit it is a strange noise it makes under load. im stuck as i cant sell the car in the state its in as who ever comes to buy will hear the noise and wont want it.

ill have to double check that number thoas that is off the top of my head but it stated over boost and said it was intermittent.
the garage that did the test said they thought they would have to look at the turbo as they thought the turbo was the likely cause and that the vanes might be sticking due to crabon build up. does that sound likely. id really appreciate some advice as its really beginning to get me down and im struggling with money as it is. i really dont want to commit to something if it isnt necessary
