Error codes - W203


I picked up a bargin, but I've just found some error codes.

Would appreciate some advise as I'm new to Mercedes. I took it to an independent so called specialist the day after I bought it, and they totally ripped me off and gave me a crazy diagnostic without proof of the codes actually existed. I had the below generated by Torque Pro.

Any help would be greatly appreciated.

Thanks in advance.
