Hi purchased an 1998 mercedes clk320 and within 10 miles the car suddenly died. After a couple tows and the inability of mercedes licensed mechanics to diagnose mainly due to the ecu not spitting codes I got it home determined it to be a faulty ecu. Opened it up and sure enough there was actually burn marks on the case. I sent the unit off and had to wait a month to receive the unit. Plugged it in and the car run excellent. There were 3 issues abs esp lights remained on, car sometime wouldn’t shift to 5th gear and said I had a faulty brake or tail light one was a little dimmer. Three weeks later the car wouldn’t start and had all the ecu symptons of fan on high, key turned, all lights and equipment operated, when jumped starter turrn and fuel pump operated. I purchase two donor ecu’s and took immoblizer
The symptons are:
There is plenty of voltage from battery
If I turn ignition quick there will be a click and almost feel like it is beginning to engage starter. Turned slowly there is no sound. all lights etc work. computer links to scanner but throws no codes. fan is back to normal. K40 and all fuses appear good. new brake switch installed. we tried a number of reset procedures with no results. So here’s a few thoughts.

My Mercedes won’t crank, the lights come on when someone has the cable hooked up to it but still won’t crank. The key will turn but won’t say anything.it won’t even start when someone charging the battery from they car. And my battery only about a year and half old.
