Looking to purchase a W204 next week. I ran it through a PPI and it had minor oil on the engine that is pretty common on most cars, nothing major. However, the guy ran his obd2 computer and he came back with three codes: under ECM 0745 (cylinder 1 lean), 2091 (cylinder 1 misfire idle), and under ESED 9EAF97. I can't figure out what the last one is based on Google searches.
The first two I assume are being caused because they need new plugs, coils, injectors, o2 sensors. I have those on order for a basic tune up.
Is there anything else I should be considering based on those 3 codes. Btw there is no CEL and the car ran fine. No noticeable problems and if the guy never ran diagnostics on it you would never have known either. It passed smog the day after as well.
Any invites? I'm pretty much set on buying the car.. just need to wait for the bank to open and the man his cash.
There are a LOT of C63s out there. If it were me, I’d wait for one without any problems.
I've waited a while and this was one of the better ones. I live in Norcal and unable to travel far to grab one. Theyre pretty scarce up here in the bay area.
I figured since there hadnt been a tune up reported the issue would possibly be a simple tune up fix. It's not anything I wouldn't do if I bought a new car too (same haul over I did when I got my 2010 S4).
lean and misfire on only one cylinder is an odd one. for vacuum leaks, pcv, or throttle body mounting plate issues you'll get bank lean but not misfire. could be the ignition coil is bad. original ignition coils go bad over time.
The code reader the PPI dude used just said "stored" and from what I read it could be a bad spark plug and got fixed; therefore, the code was "stored" since it was an engine issue
But I went ahead and bought the car and bought all the parts for a basic tune up. Will address spark plugs first then work my way around the coils, injectors, etc if necessary. Gonna start with the cheaper and more common stuff first.
27.5k in Norcal. I havent seen another one around this price or mileage in a while. I feel like that's a fair price. It's just the base C63 and it has limited options on it (whoever the initial buyer was cheaped out on options).
Update:I ran my OBD2 scanner on the car as well and no codes were given to me. I have another scanner tool I can use later but for piece of mine everything seems to be mechanically sound. Going in for a tune up next month.

looks good! i would focus on plugs & injectors as you mentioned and all fluids. I didnt replace my ignition coils when i did my injectors/coils, but if you still get a misfire, you could rotate the coils and see if the misfire moves to another cylinder.

if your plugs and injectors haven’t been done yet, I’d definitely get those done. Some people here have had issues with injectors that have stuck open and flooded the cylinder.
when I replaced mine at 86k, they were absolutely disgusting and covered in filth

I haven't done it yet but I bought all that to tune up next month. Got the fluids to change jic as well. Then hopefully i should be good til the next oil change
