I've been getting intermittent problems with the AYC warning light coming on usually after an hours drive or a bit of more adventurous driving. The local dealer ran the MUT-II and diagnosed a problem with the Throttle Position Sensor (TPS). Now its been back for a second check they reckon its a fault which is becoming common on the VI's and its not the TPS but part of the ECU and its a straight replacement of the unit. The car feels OK but losing the AYC just when I need it ain't too appealing !!

Anybody had the same diagnosis ?

Is it just AYC function that ceases or also rear diff function? If it is just AYC, could you sell your ECU to me please?
