Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hi Herb, the red warning light usually indicates low system pressure. I'm afraid this might be another issue with the ABC pump. You will need to get the car connected to the Mercedes Star Diagnosis tester to at least read out the fault codes in the system. The codes will point to the specific problem. With the SRS light also coming on there could be a battery voltage issue. That would not be as disastrous as an ABC issue. You will need to get the initial diagnosis done to give you some direction. I would expect a 1 hour diagnostic charge for this at the dealer.
Let me know if you have any questions.
