ESP&BAS control unit repair?

Hi everyone,

My battery died, the seats were all the way back and I jumped it and then replaced the battery. My dash lights came on and I could not get the ESP, ABS lights to turn off.

I tried turning the steering wheel right and left, etc.

So, I took it to a independent shop (only work on MB) and they diagnosed that the control unit is bad. Ouch, these are expensive. I can't find a used one and my discount price from MB is $1,700.00.

Mercedes part 4635451432

Bosch 0265109495

Has anyone taken one of these control units apart and if yes, can they be repaired?
I've done a google search and called several repair shops, who then say they don't repair them.

Thoughts and help appreciated. This is the last thing to fix and then sell the 2002 G500, because I bought a 2014 G550.

Thank you.
Alex.

I was lucky to find a used one.
One of the valves was frozen.
I took it apart as far as I could and found web information that the brain can be replaced separately

Re: ESP&BAS control unit repair?

Thanks Harold,
I found a shop in upstate NY that says they can fix it for $275.00.
I sent them the error code.
I’ll update after I get it fixed.
Thanks
