Mercedes E320 CDI W211 revived after installing new ECU kit

Remember Mercedes E320 CDI W211 that stopped working a while ago? It has been resurrected with a full ECU / EIS / ESL kit from a donor vehicle! Turned out it was the EIS (electronic steering lock) that got corrupted and lost coding. It was all caused by water ingress that caused some water damage to modules. Water was getting through the bulkhead due to blocked drains under the bonnet. Since cleaning these out it dried, but electronics didn't take it lightly. Now it's back and we'll be sorting other problems with it.

By the way, I bought the whole ECU kit that included a lot of modules, all you really need is the main engine ECU, EIS (electronic ignition module) and ESL (electronic steering lock) - this should be enough to start the car, on my one I've replaced few more, due to being water damaged - front SAM module for instance. Swapping those will cause issues with VIN number not being correct in some parts of the system, also mileage issues. Will try to iron these out soon, will document the process, but my main aim was to make the beast moving under it's own power again, so I can get the drive back. Only to put Alfa here, as this one needs further investigation, and since they are just projects, I will not bog down the garage with them. More videos on this topic will be coming soon. See you shortly!
