PhatDad Posted April 28, 2011 Share Posted April 28, 2011 Hi all,My car has been lacking power for a while now. When you accelerate it does so fine but if you take it up to about 4k revs the power suddenly drops and after this whenever you accelerate it seems to be ok but then halfway through the rev range for each gear it just doesn't seem to go anywhere. It also seems to stutter at times even when the car isn't suffering from the problem AND once in a while if I accelerate hard in first gear the car cuts out.Once the car loses the power I have to turn it off and power it up again to sort it.I've just given the engine a once over, not that I know shit about engines, and have noticed a peach/orange coloured sort of flaky stuff. I've taken pictures below.https://picasaweb.google.com/phatdad/Ap ... directlink Quote Link to comment Share on other sites More sharing options...
Stu Posted April 28, 2011 Share Posted April 28, 2011 same engine thats in my Audi its going in to limp home mode for some reason you really need to get it plugged in to a machine ( VAG COM/VCDS) and get it scanned it will point you in the right direction but it aint cheap not sure if anyone on here will have one!! but if you can afford the £250 buy one yourself it will pay for itslef in no time first things to check though are the vac pipes to the turbo you could have a split in one of these and not working properly causing low boost also check the intercooler for leaks and the intake pipes it could also be the actuator valve for the turbo a clogged up EGR valve the MAF (mas air flow meter) or boost sensor!!

Stu Posted April 28, 2011 Share Posted April 28, 2011 Well if that went straight over your head then you need to take it to someone who knows I could talk you through a few things to check but won't be until I get back on my pc Quote Link to comment Share on other sites More sharing options...
RicKsTa Posted April 29, 2011 Share Posted April 29, 2011 Pretty much what Stu said..I would say possibly EGR valve sooted up or check your intercooler...Make sure you intake pipes are all sealed and check you airbox for no clogged up crap.. If you have no idea on how to do this, pay a proffesional (just dont go to a stealers) Quote Link to comment Share on other sites More sharing options...

JamieK Posted April 30, 2011 Share Posted April 30, 2011 Sounds to me like the turbo is overboosting, usually with vac pipes itll be all of the time, is it using any oil by any chance? Quote Link to comment Share on other sites More sharing options...
