Error codes PO61A and PO62c
I have a 2015 S550 and a few issues popped up recently. First the ECO start feature stopped working then after a few weeks several message appeared such as ABS, Presafe and ESP appeared. Thereafter, the car started to jerk and I couldn’t get the rpm above 1,000 and the Check Engine light came on. The error read were PO61A and PO62C. After resetting the codes they reappeared with the vehicle jerking. I stopped the car, turned the vehicle off and restarted. Then I reved the engine and all was fine and the Check Light went off after 100 miles.
can anyone help me solve the above please? Much appreciate any support.

have you seen any water inside of the vehicle? pat around the front passenger footwell carpeting, rear passenger side footwell/under seat. Sounds like a bad SAM module based on the codes.

Vincheung, many thanks your response. Just check both locations you referenced and they are both dry. Now, these issues did start after a heavy storm so I believe you are correct in that the issue may be moisture related. So what are the SAMS to check and where are they located?

I am actually not sure exactly where and the number of SAMs the s550 has, typically they are located under the passenger side dash under the footwell carpeting, under the front passenger seat. I think in one of my previous MBs there was one under the back seat or in the trunk. You should check the trunk carpeting and spare wheel storage area for water also. If you go to youtube you could possibly find some resources on SAM locations and troubleshooting. When you get a chance, locate all drain outlets and clear them out to prevent future water intrusion.
