147 JTDm 16 Lacks Power
Just wondering if anyone can offer some advice. I have a 2006 147 Jtdm 16v. Driving along, all of a sudden, it lost power - wouldn't do over 30 mph. Came up with a MCSF error on the dash. Plugged it into the laptop, there was an EGR valve error. Replaced the EGR valve, still no power. Finally found the VGT valve pipe had snapped off. Replaced this electovalve - now finally the turbo cuts in, and the car drives ok. It is no where near as quick as it used to be. Acceleration is slower. Just wondering if I should have disconnected the battery for an hour or so - so that the ECU could re-learn the new component thresholds ?? or does clearing the fault make the ECU re-learn its settings ?
