Finally, my dealer back from vacation had another shot at it. Cleaned the MAF and PCV increased idle to 700 Rpm. For as long ECU tolerates that in memory. We even checked the VIN against present firmware ECU. Was correct one. Checked timing chain for problems. No error codes. After cleaning and raising idle runs tolerable. Strange thing we noticed note E11 1.6 petrol have problems closing windows causing engine to vibrate at final shut. Especially noticeable when operating driver side and passenger buttons. We compared two 1.6 petrol with same behaviour. Anyone else noticed this?
Disconnecting battery will not reset ECU on 2011 E11. Only a few dumb user values. The 5 times pedal up and down in 5 secs throttle valve relearn is also ignored, not present. Maybe earlier models from before 2010? So you are stuck with the dealer and need be carefull that no unnecessary pricy parts are exchanged or lot unnecessary hours are put in. This involves buying , see thread the buying of a cheap elm327 Bluetooth dongle and decent app on your mobile phone, costs 12 Euros together. And logging data to outrule certain things. Best you do this before you car develops trouble to have the to be values running correct.
