Still waiting to hear from the indie... they were booked up until the end of the month but promised to fit it in as soon as they can so hopefully they will get to look at it soon.
Finally resolved! A new left front SAM unit has solved the issue. STAR had been unable to communicate with the engine and ESP systems and the garage was worried that there might have been an issue with the EIS unit but got a call yesterday to say that they had fitted the new SAM and everything was working as it should. I have just been to collect the car complete with it's new MOT (6 weeks to the day since I originally tried to get it MOT'd). It's taken a while but it could have been a lot worse/expensive
Hi thereI'm hoping it's not a fried ECU - That's way beyond my capability and I daren't think what a replacement will cost me. On Monday I checked out all the fuses and fuse boxes. Everything seemed fine and there is no sign of water ingress/damage anywhere or any corrosion. I decided it was time to get the car to a Merc specialist and using the specialist finder on here, discovered Auto Technic who were a short distance away. The car, still stuck in Park, has been delivered there yesterday and I now await their findings.
The front left SAM unit (under the front left fuse box) had failed. There was no sign of water damage or burnt out components but the failed unit meant that numerous circuits were unable to communicate (including the diagnostic socket!). A new SAM unit fitted and coded to the car solved the problem. I hope you get yours sorted soon.Hi there
I know this post is a few months old, but I have an SL500 with EXACTLY the same issues........Did you get yours fixed in the end? And if so what was the issue...thanks in advance
Cheers
Many thanks for the info. I'll take the pluge and get a SAM unit. I love these Mercedes cars but they can be trying when an issue arises. Especially when these "specialist" just want to throw expensive parts at it until they fix it or you go skint LOL. Ill let you know how i get on.

Finally got chance spend some time on this no crank issue. I checked the pass side sam and its brand new. I should say at this point that I bought the car as a "non runner" in an auction...so I deserve all I get LOL. I found a bill inside the car for alomosr £10,000 yes ten grand trying to fix it. It was in a MB specialist for 13 months....in the end they wrote the bill off as they hadnt fixed it. Its has ESM gearshitf replaced, NS SAM power distribution module in boot and several relays. Everything works but will not crank, cent locking not working and rad fab runs constatly when connected. Also EIS won't let key turn unless you disconnect and recoonect battery (in boot)The front left SAM unit (under the front left fuse box) had failed.
