My 2008 1.9 Golf TDI (77kw BLS engine) had a failure on 176,000 km and I thought it good to replace the rings, bearings, camshaft, cam lifters and injector seals with the engine open. I fitted standard rings and made sure that the rings face the correct way up. Did it all myself except the skimming of the head and valve seating which was done by a professional workshop. Also had to do the rocker adjustments to the correct measurements as per the VW Workshop manual.
On top of that I replaced the turbo (which comes a complete unit consisting of turbo, manifold and actuator) as the turbo shaft was broken. I did not adjust the actuator setting though.
The idling is now very inconsistently at low revs(800r/m). As soon as the revs pick up it seems to disappear. Took it to the local VW dealer for a check and they informed me that the compression is low (+-16bar/235psi vs normal compression of between 25bar/370psi to 30bar/440psi.....not sure if it is the correct measurement?), but that this consistent on all pistons. There is also a loss of power, as though the turbo is not really kicking in.
Any suggestions on what I could do?
