If you go the OE route the new ECU is going to require coding in & adapting, make sure your scanner can do this, we had one dropped in from a local garage a couple of months ago who's KTS wrongly coded the unit - we had to iron it out with the Autologic.

Apparently the earlier Teves MK60 ECU's the KTS can code & adapt, the new ones it can't.Bosch are working on it.

If you use Actronics no coding will be required,they send back to you the unit you send to them.
