Hello,

2006 1.8 TDCI (125HP). A refurbished turbo was put on it (+oil and filter,+gasket), electronics remained the same (old turbo ate the oil and hummed). When accelerating, it pulls in from low revs around 1700 revs for a moment, as if it "misses". After that, it accelerates normally. It didn't do that with the old turbo (it didn't jerk). It didn't touch anything else.
After stopping, a sound comes from the engine compartment..as if the air is escaping from somewhere."farting sound" My question is, can the turbo handle the engine like this (geometry adjustment problems?), has anyone had this or a similar problem? Maybe go the other way?
Thanks!

This sounds like the old turbo has clogged the exhaust system, you can check if you undo the exhaust system head pipe and take it for a short test drive. If the problem goes away, you have found the issue. Please let me know what you find.

Hi!
The fault was in the turbo electronics. It was repaired and calibrated. The error is gone.
