Ok so the ML is fixed, now it's the C32's turn.
I have an issue with my W203 2003 C32, the main problem is a "COOLANT VISIT WORKSHOP!" message and the radiator fan is not working. I have been using the car with this message for a couple of months as I have had not had the time to look at it. I am a shift worker and don't encounter any traffic on my journey to work.
I'll try and be as brief as possible with this explanation:
The car was off the road for about a year and was put off the road fully serviced and working well, I had just put a new battery in it. Every few weeks I was starting the car and letting it idle till it warmed up, then switching it off. On one occasion I went out and found the battery was completely flat I started it with jump leads and didn't give it much more thought. Once I started using the car again the coolant message came up and I also noticed the comand system (radio) was not switching off when I removed the keys. The steering wheel buttons also stopped working the volume etc. These two things happened at the same time so wonder if they may be related..... The rest of the car is working as normal.
The coolant level is not low and I have checked the supply to the radiator fan (12.7v) at the plug with each other and to ground, I do not know how to check the two other small wires.
I have attached screenshots of the diagnostic error codes from front and rear SAM's, engine and instrument in the hope that someone can point in the direction of where to go next. There was a load of historical error codes relating to low voltages which I cleared then I took the car out and this is the error codes that remain. The modules that are being scanned are identified at the bottom of the screenshot.
