Can I merely replace this DME with another similar DME ? If so can someone kindly provide details of stockists of such secondhand equipment.
Thank you

It has to be an exact match to the one in the car, and will absolutely require substantial coding by a dealer in order to work at all.

The new DME will need to be coded to your existing key and immobilizer. This can be done by the dealer or you can ship all 3 to https://www.ecudoctors.com and they can test and do the coding for you.

If goes further than that, the DME has to be coded to the car's equipment features: OBC, cruise, factory Litronics, etc. Matching the DME to the immobilizer and keys will get the car started, but then none of the other features would function.

Any suggestions where I will find secondhand replacement units

I would start with the ecudoctors as they can repair water damaged DME's. If you give them a call they will be happy to help you.

They require the cars VIN and from that they can get the options that they need to code for.
