Hi all,
I'm calling for help before giving in for the mechanic.
My ride is a '01 TT 1.8T MK1 with REVO and a few more mods
Situation:
My turbo used to run at 15pounds top.
Recently I had a clamp in the cooling circuit failing and letting most of the pressure out. I drove just a few hundreds meters into the shop to get it diagnosed and fixed.
After fixing it, my turbo started running at 20 pounds top. Nice . However, as a result of the higher pressure, another hose in the same circuit popped out, a 90Deg elbow behind the head. This time I was far from the shop and home so I had to drive in that condition for about 10Km to get home. Obviously, if you never experienced that situation, the car runs very bad. I had to rev up to make it move slowly through the intersection. Otherwise it would just stall.
Problem:
Once at home, I put the hose back in place and tightened the rings. Hoping to see everything back to normal I go out for a test drive. Sadly, the car is no longer running smooth. It doesn't hold the idle and hesitate a lot before getting on higher RPMs and pushing more normally. I drove it for a few Kms hoping to get things rolling back to normal but no success.
It looks like something got screwed up with my long drive with the hose out of place.
I seem to remember reading something about resetting something after fixing something... very vague
Any suggestions would be greatly appreciated.

 

You probably have a code protecting the motor. You need to reset the codes with either an obdII device or unplug the battery for a few minutes but make sure you have the radio code before hand or it will be locked in safe mode.

 

Man.. that worked just fine. Thanks a lot for that.
Could you please give me some indication about which code I have reset with disconnecting the battery?
I suspect the the raised pressure from 15 to 20 pound was triggered by some codes as well. It seems it's gone back to the normal 15 pounds now, but I'll have to confirm that. I'm relieved because the hoses were starting popping out every other day. I don't think I have a circuit appropriate for that pressure.

 

Wth a revo tune, you should be making 20-23psi. Get some time and pull and clean the boost hoses and you may also want to swap to tbolt clamps instead of the worm ones.

Don't know the code number, but it's a pressure loss between the turbo and throttle body.
