Has anyone mentioned the problematic M104-24V main wiring harness in the engine bay.
Check to see if it has been replaced.
Pull back the harness over wrap and look for areas near connectors where insulation is deteriorating.
Very common as Merc used an environmentally friendly insulation on the wiring which didn't stand up to engine bay heat.
Early M103 and M104 didn't have this problem.
Will affect performance.
Harness alone may run over 1000 sterling .
If you have the VIN you can run it through EPC and get the data card.
This will indicate what options the vehicle has.
