disconnecting the maf will give the ecu safe values so it might help work out some problems, but i aint all that sure.

cheers will give it a go the car is being a right pain at the moment everytime i put my foot down it just holds back on me

mabye n75

 

[rich2310]

i changed that about 6 months ago it would go that quick would it

 

[__B3NNY__]

Anythings possible, You got a boost gauge?

 

[rich2310]

no not got a boost gauge went to forge last monday and the car has a fault code of negative boost devation

 

[__B3NNY__]

Im not a vag com geek by any means as im just getting used to it myself but i think that could either mean the N75 or you have a boost leak somwhere. If your car is standard and your not modding it any further i have a autometer boost gauge for sale.

Check the hose from the top of the DV...

My item had been smelted causing your symptoms, either that or go to Maplins and buy Isopropynol (?sp) Alcohol and give the MAF probe a good going over..

Car's never ran better after that!

No worries mate, Have you changed all your vac hoses for silicone ones? If you havent i would (and have) Makes the engine bay look better and could also be a cheap fix to your problem!

David.

 

[rich2310]

yeah have change all the vac hoses along with the tip and dv service

 

[Funkyfin2000]

i have similiar probs!

not done the N75 yet...

boost gauge just shows 0 when u floor it and then suddenly comes to life....

weird....not done N75 yet but maybe a N249 bypass may help?

 

[rich2310]
