E500 Help Weird SBC problems? Maybe Wiring?
So, to start I had a SBC failure from the car sitting for 3-4 years bc of the air suspension (i converted to coils). Then I took it to Mercedes Dealership and they replaced the SBC pump and didnt charge me at all and did the service. Then the car worked well for a month or so and then when i was at a stop light waiting for the green light, the brakes failed completely and the pedal went to the ground so i used the e brake and took it home carefully. Then I took it to the dealership again and they charged me $400 for the inspection bc they said the SBC wiring is not covered by Mercedes and that they are still not sure where the fault is and i need to pay $500 more for them to find the issue. So, I just took it home. After the car sat, I replaced the alternator, voltage regulator, battery, aux battery, and fan assembly. and ofc fluid changes. Now, the car will randomly fix itself and brakes will work and sometimes will not on start up. Then i turn it off and on and it works again. When brakes fail i get these codes Engine: p2000 p2010 Sbc:c217A P2087-008 P200F-008. I'm thinking some wiring issue But Im not sure. I heard also mercedes had a upgrade ground wire for the sbc but Im not really sure. Any information would help! Thank you,
