Hi all, this is my first post so sorry if it's in wrong location. I recently had the oil changed in my slk 200 kompressor r171 and, three days later the engine warning light came on with error code p200a bank 2/5 hot film mass airflow sensor the car was running fine at this point so the the code was reset however a couple of days later the light came back on with the same fault code but it ran a little lumpy on tickover this time, the next morning it started miss firing and it sounded like it was only running on 3 cylinders and cut out the next set of fault codes were p200a again and p2054 cam shaft adjuster the car sounds like it's racing over like there's no compression It occasionally gets a burble like it's going to fire up but doesn't actually run. Any ideas? I don't want to start replacing sensors if it's the something else that's causing the problem.

Head off job to inspect damage, not a cheap repair overall.
