Took my car up the motorway today and it pulled fine in 1st to 3rd gear till i hit about 80mph and then as i was in 4th couldnt get any further quick acceleration.It felt like turbo lag and the only way i could get more power and speed up was to ease off the gas a bit and then on again.Can anyone confirm this is a turbo problem or something else like a sign of a failing coil pack or spark plug replacement?

could it be heat soaking or check ur turbo inlet and outlet hose, they might be coming off

Checked the turbo hoses alls ok.Whats heat soaking you refer to Allwheelgrip? Could it be bad spark plugs or coil pack(like a misfire issue) as there now due a change from Audi 80k service.
I hope its not something serious.

I guess you have not got your copy of VAG-COM/lead as yet??

could be a coil pack as that makes you loss power on low revs, my coil packs went down around 80k.

I replaced all 4 at £25 each, you could buy one, change it in Cylinder 1 and then drive, if the problem is still present place the new one on Cylinder 2 and replace the old one back to cylinder one to find out which one it is...

However VAG-COM could tell you that within a min.... (i have got 3 old coil packs which i replaced to save any hassle which work fine at home which i guess you can borrow to test) just drop us a £1 or 2 for the postage on the basis it gets returned)

Cheers for the kind offer rick,i havent got vag-com as yet but as its due its major 80k service now so gonna put it into audi dealership anyway.Its a bit weird as ive got power lower down in the rev band but looses(hesitates) after 4000 rpm under load and then comes back again.Maybe its the MAF playing up??

 

[RickT]

yeah no worries, just remeber the coil packs are £25 each and are only held in with 2 screws so dont let audi for charging the world!

yeah it could be the airflow meter.. best get it on VAG-COm as we could be here all day as you well know!!

Cheers

heat soakage is when the turbo and intercoolers are hot and ur only blowing hot air now, its normal though

Would this in turn be a cause of turbo hesitation(lag feel) then?Is there anywayof correcting it? cheers t-sport
