Forest c280

I have a '98 c280.. When I turn the ignition key, it won't start or even try to... The mechanic replaced my ignition lock/module, but that didn't fix it....!! (It started 2 -3 times and then left me stranded...)I had the car towed back to his shop and the mechanic replaced the Starter Relay, and for the moment, it's working..(fingers crossed)..

Here is my question: What are the odds that the Starter relay AND the Electronic Ignition switch complex could fail at the same time?

It seems to me that the mechanic first misdiagnosed the problem, by replacing the Electronic Ignition switch complex ($1400 P&L), and then after my car failed again and returned to his shop, he 'got it right' with the Starter Relay, (which is $200 - $400).
I am meeting with the owner soon to discuss this and would like some feedback from some knowledgeable MB World members....
Many thanks!

Sounds like you hit the nail on the head. I always ask for my old parts back.

Thank Mark... I got the Starter Relay part, but didn't get the 'big one', Ignition.. I just assumed that the mechanic had testes it properly... (a lesson learned).
