Hi,

I need your help!

Today I was driving my SL 600 2007 hard on the limits. At high rpm just before going to 4th gear I heard a small strange sound (not metallic sound) and then I lost power and the check engine light came on. I was still able to drive but with reduced power. There was no bad metal sound or anything.

I parked the car and read the error codes from the obd and there were many error codes (more then 10 and saying misfire on multiple cylinders and more codes but I didn't know then how big the problem was so I didn't pay so much attention to it)

When I tried to restart the car the ignition comes on and the instruments works but when I try to start the engine the starter is not responding at all, not a small click or anything. It also says ABS fault and ESP fault on the instrument panel. No error codes at the moment.

I have tried a new start battery because its easy but it didn't help. I don't know how to proceed but maybe someone here have any idea?

I talked to the local dealer today but in Sweden where I live it's a very unusual engine so not so much help from there.

Any idea is appreciated!

Thanks in advance
Jan

Because you dont have xentry to give you the specific answer---start with applying voltage to starter--what happens----then move on to the starter circuit bla bla

Now I know more but still needs some experience help.

One fuse is blown and blows directly when replaced so there is a short circuit somewhere, anyone that knows where it's most likely?

This is the fuse description :

f43 30z RDBU 2.5 Terminal 87M1e connector sleeve (Z7/35) 20
Rear fuse and relay module (K40/5)
ME-SFI [ME] control unit (N3/10)
Fuel injection valves (Y62)
Valid for engines 272, 273:
Ignition coils (T1/1 - T1/6)
BKVT 0.5 AAC with integrated control additional fan
motor (M4/7)
Valid for engine 113.995 (AMG):
Camshaft Hall sensor (B6/1)
Valid for engine 275:
Radio interference suppression capacitor
(C4)
ECI ignition system power pack (N91)
Boost pressure control transducer (Y31/5)

Post your VIN and will look at the starting circuit early next wek

A small update.

I found out that the ignition power transformer or the coil pack is the reason for the fuse to blow.

I have replaced the fuse and got the starter to work again so now the ecu communicate again.

It starts and all 6 cylinders on passenger side gives misfire code, it runs on the left hand side.

I have ordered a used transformer to try with.

Is it possible that the coil pack can cause complete bank to fail?
