Hi.
After much work/illness/head scratching, I have finally rebuilt the engine on my S55 AMG, Overhauled the two heads, new timing chain, new oil pump and drive chain, new water pump, other stuff I cant remember.
The engine is now running well, and I can (sort of) move the car.
The problem is, that I can only start the car with the keyless go on top of the gear selector, the EIS doesnt work properly.
It moves the steering wheel when I put the key in, but does not illuminate the dash, and does not start the engine.
Also, the gearbox will not release when I press the brake pedal, it will only release if I smack it with a rubber mallet!
It seems the brake lights dont work, the left one is on all the time the ignition is on, but the central does not come on, neither does the right (although the bulb may be blown).
The only other thing that doesnt work is the courtesy light when I open the doors, they all work with the switch front and rear.
I am using an Autel Maxidas, and there are a lot of faults that mention circuit 15 and one which reports 15a.
I have searched the internet, and tried to make head or tail of the Mercedes wiring diagrams, but I cannot find much information about this elusive circuit 15
I have a feeling that all of the faults are connected, perhaps not the courtesy lights, but the brake lights and gear selection certainly.
There is no brake fluid in the system at the moment, and the pads need refitting, but only after the discs have been skimmed as they are rather rusty after 2 years of no use.
All other electrical systems work.
I could live without the EIS as I always use keyless go, but I dont like the idea, and I need it to reset the throttle to the new 80mm body.
I have tried fuse 78, which seems fine.
The engine ECU has been serviced and repaired after water got into the plug and a few of the pins broke.
There are quite a few fault codes on the reader, but these can be ignored as they are for the suspension, which has been swapped for coilover, and the sound system, which has been swapped for an Android system with seperate amplifiers.
Can anyone suggest anything that I could try? I cannot get it to the dealer because it is not roadworthy yet, and has no tax, Mot or insurance on it, and the nearest dealer is 30 miles away.
And if someone can explain in plain English with no technobabble what the hell circuit 15 is, where it gets its power from, which relays/fuses could be faulty, I would appreciate it.
Thanks
Steve
