Hi bro,

been told to ask u to help me figure out my problem.

Car : 2007 gti mk5

the problem started after going stage 2 remap with catless downpipe..when ever i go downhill for a long time and if i stop on a junction and started to move again a big bluish puff of smoke came out my exhaust and then all is normal,no smoke on hard acceleration,only while driving downhill with off throttle.

here a video of my problem

i have changed the turbo and changed oil from 5-30 to 10-40 with no luck,changed my pcv and then went full pcv delete and still same,i think i have 2 options now:

1- valve stem seals.
2- piston rings.

car does not smoke in 1st startup in the morning.

i hope i can get this solved before i go down with piston rings.

Thank you

Hi bro

valve stem seals or piston rings?

Shoot me an offer on the ecu mang.

i have a question pcv wise if you can just vent it into the exhaust like you said why cant you just run a hose to the bottom of your car and let it just run out? i dont understand what the importance of it feeding back into the engine after the CC is?
