2006 C230 Fuse #53 keeps blowing and car won't crank/start
this car is really giving me hell lol, I first thought it was the starter then I jumped it direct and it cranks just not with the key, checked all fuses in SAM module front and rear and all are good except front SAM fuse 53 was blown, replaced it and when I turn ignition on it blows the fuse. I put a test light to it, end to positive and tip of light to fuse and seems to be grounded out somewhere, I'm stumped on this one, any help would be great help..

have same problem
Everytime I turn ignition to position 2 fuse blows 25amp fuse. Lost not sure which way to go car is a 2006 C350 sport. Maybe front Sam unit? Anyone with past knowledge help would be appreciated, very desperate at this point. Can't communicate with ecu for fault codes.

Burnt ECU
Easy fix, remove ECU and have it tested. Buy used ECU exact numbers (eBay). Have eBay ECU programmed to your car. Totally cost around $500.00. I will help you with this if you need it. Plug and play, back on the road like new again.

2006 slk350 70,000mi. Also fuse blows & no crank
I have same exact issue and here is what I found - ECU board inside of metal housing has shorted to housing right beside one of the white insulator strips & exactly where a capacitor is located on board, to me this is a factory defect, not enough insulation to isolate voltage flowing across back of ECU board, my board is toast and just a matter of time until a replacement ECU does the same thing, It sucks having to take apart a new ECU to insulate behind the board but it's the only way to end this problem,
