I am pondering if my P0340 issues are being caused by a failing engine controller.
The big point is, cost. As my car is now worth about £1500 I don't think it is worth paying for a new ECM and then having to pay for programming at the dealer.
The question is, if I was to get a second hand unit, what needs to be done before removal to be able to re-program it to my car? Or do I need donor car pass details?
How much would a pairing to my car be? and what would I need, eg pass code etc?
Also, can OPCOM do this pairing? - It just happens that I know someone with it.
Part number is 9158670 or Siemens 5WK9153
Have I missed anything?
