Title: Power loss
Post by: Clock'd 0Ne on February 05, 2009, 15:41:54 PM
I think suspicions have been confirmed about the power going away every so often, taking tha car back up the M1 from Sheffield it simply would not accelerate past about 70-80mph, even if I dropped back down to third. The power just seemed to go for some reason. Since I cant use a vagcom is it worth me just getting the MAF changed if thats likely to be the problem?

check theres no damage to any of the hoses, could be the boost leaking after the turbo

check the actuator linkage is intact and that the wastegate isnt stuck open as a result.

Im at a loss for an answer to this.

the power loss will either be boost loss due to a split intercooler hose or fueling due to the duff maf sensor.

you could try unplugging the maf sensor to test it, not sure on Audis but on rovers it can restore the low down fueling but the topend fueling will still be limited.

its always the same on the overrated VAG diesels - airflow meter or a boost leak.

Or that N thingamy valve - or the turbo if its a variable vane type
