Looking for someone that has the schematic for the following ECU:

Bosch 0 261 200 473

964.681.124.00

Type 911-MW-DZ-01

I am trying to replace a capacitor in the lower board (non ribbon board) that was soldered in location C457 that appears to be a broken cold solder joint. I don't know what that circuit does. It's 9013pf, 63 volt MKK capacitor.

If its some obscure irrelevant circuit I would know if I should pursue it.

Thanks for your help.

Found the replacement Capacitor. Should install later this week. Still would be nice to know what circuit it effects if anyone has the schematic. Tks

I'm not aware of any schematics available for any of the motronic units. There are a few places that work on them who I'm sure know. Steve Wong would be among them, if he's willing to share the info. How did you diagnose the bad cap to begin with? Find a physically cooked one while looking over the board? Were there any driving symptoms?

I dont know if there are subtle symptoms. I actually saw the broken lead during inspection. I should have my part in by tomorrow and reinstalled by the weekend. It's possible that its part of some relatively insignificant system not performance related.

Steve does not have the schematic. I found other ones but not the correct on.
