Title: Doesn't feel right?!
Post by: Ady TDI on 04 August 2008, 11:19
Went out in the 150 on saturday and it never seemed to have much power, when i first bought the car the boost would kick in at 2000rpm, but on saturday i never noticed any boost, i just checked the intercooler hose and that is fine, what else could cause this?

Thanks

Edit - If anyone is around London Middx that can run Vag for faults i will be greatful and supply beer tokens  :smiley:

split pipes, MAF, blocked air filter / fuel filter as a starting point

whats it like through the rest of the rev range? do you notice lots of black smoke out of the back?

Cheers Rhyso, maybe if i can get the car running right i'll keep the 150  :laugh:

No black smoke, no smoke unless i rev it hard on idle then it's just white, 2nd and third gear seem to have a bit more poke at the 2000rpm

hmm white smoke isn't usually a good sign!

what gear does it seem to lack power??

1st gear seems to be no power even after the 2000 revs, then once it's in 2nd & 3rd at 2000 seems to pick up.

Just been looking at the faults the Vag picked up when i had miles to empty done, this was the post:

So it's either the boost hose, or MAF?

i take it you've replaced the Coolant Temp sensor already then?

unplug the MAF and take it for a quick spin - if its better than the MAF is knackered

Haven't replaced the temp sensor yet :embarassed: i unplugged the MAF (if it's the switch on the air filter?) and it was worse to drive
