Hi All - working through all the problems with my SL500, it all seems to stem from a major water ingress into the Drivers side footwell. Unbelievably, although the heater box drain was virtually blocked, there is absolutely no sign of water ingress into the Passenger (UK) side, bone dry and actually looked quite new and clean under there! Upon removing all the fuseboxes, SAM units and ECU's from both front corners, they are all showing signs of corrosion and moisture damage, including the main engine ECU. removing the cover off the ECU, there is pretty serious corrosion and damage all over the main PCB, including a couple of suspected blown components, so it is looking like I'll have to replace it.
I have STAR, and although I haven't yet had a go at coding any ECU's, I feel fairly confident at having a go at the SAM's, but my question is this :-
Is it possible to code the main engine ECU just using STAR? What are the implications for the DAS and immobiliser/key info - is this information copied over when you recode it, or is some special 'dealer-only' magic required as well? I have found a couple of cheap ECU's for sale, but just want to be confident about recoding before I buy. Any help or info would be greatly appreciated. Cheers
