Loss of power
« on: 08 October 2012, 13:44 »
Golf mk4 1.8t AUM

Right when I start engine the car runs fine turbo boosting good and nothing happening different
But after about half a mile when engine is getting warmer the car does not rev as quick like I'm not pressing the accelerater enough. Can still hear the turbo spoolin.
The car is ticking over fine, no boost leaks or other problems at all. Also no fault codes

Does any one have a idea? Been looking and it could be maf???
Any one had similar problem?

it'll all be guesswork unless you can get some decent logging data from the engine. Try cleaning the throttle body and intake air temp sensor to begin with

you can also remove the plug off the MAF and see if it runs better

Faulty DV caused this in mine, but doesn't mean it's the same problem for you.

Cheers for the advice, I can't understand at all, it seems not enough petrol is been used for the amount I'm pressing the accelerator
It's lost power right from tick over to redline, consistant.
I tried the unplugging the maf sensor but I have also been told unplugging it won't help.

Right problem solved, it was the coolebt temp sensor
I knew it had to be a sensor and I started with the cheapest lol and got lucky I suppose because I had no clue what problem was.
I'm abit baffled why no fault code came up

Cheers for the suggestions

Faulty coolant temp sensor appears as a fault code under 17 Instruments rather than the engine module on VAGCOM. Well thats what Ive found anyway  :smiley:
