Got the following codes constantly now, ie reappear straight away after being cleared. Had them intermittently over last year.
12600 P3138 Intake Manifold Flap Control
08200 P2008 Intake Manifold Flap Motor Open Circuit
Also now had
12599 P3137 Basic Settings Not Carried Out
01602 Electric Drive Motor (V141) Sporadic 002 - Lower Limit Exceeded
but these have cleared down and not reappeared yet.
The engine light has not illuminated on the dash at any stage though and the car runs fine. No erratic idle or problems when switching off as often reported for the first two codes.
The first two codes are well documented and point to Intake Flap Motor V157 possibly needing replacing. I understand 12599 also relates to V157.
Does anyone know what 'Electric Drive Motor V141' is though ?
