mk5 gti problems..

(1/2) > >>

cs01uk:
Bought an 07 mk 5 about 3 months ago since owning the vehicle i have had a remap. Just before havin this done it started to cut out at junctions whilst on tick over.. I had the re map done an everythin was fine but would still cut out once or twice whilst at a junction. Since then it has started to get worse! It cuts out more regulaly but only on tickover also seems a little under power and splutters when pulling away...

Had it plugged in to a diagnostics computer and no faults where shown!

Any help????

Also fitted a forge blow off valve which has started to hiss on low revs as if its losing pressure..

vRStu:
Some things that affect idle are PCV and Oil Filler Cap.

Try removing the Forge valve and refitting the OEM one.

SeanyK:
Absolutely as above - Take that DV off and put the OEM one back on, it's surprising how many problems can be caused by the DV itself.

gazbutS3:
as VRStu said, alot of tickover issues are down to a leaky PCV

cs01uk:
ok thanks for advice i'll giv that a go.. any idea what part number i need for replacement OEM one obviously i need to upgrade it becausde i hav had a remap..
