Hello All,
i'm new to Mercedes and new to the forum. I've spent the past 10 years in Volvo D5/T5's. I was meant to be buying the wife a small runaround for town use over the weekend and had an impulse moment over the weekend and bought a 2005 C230 coupe (2.5 v6). Beautiful car. Sporty, and has an AMG pack which makes it sound great.
I picked it up with a few problems. Its only done 58k miles with warranted service history but as its been rarely driven I think it'll need a bit of work.
The seller reckoned it had been serviced last week, but looking at the oil I don't think it has. I've ordered all the stuff for a full service, fluid and brakes, so hopefully i'll get that done over the next couple of weeks.
Its smoking a bit - more grey smoke than white (defo not blue or black) - I thought first of all due to the lack of use and just needed the cobwebs blown out, but despite 100 miles since its still a bit smokey. The oil needs changing, but I cannot see water in it, and likewise the coolant is not oily.
I've bought a code reader and its flashed up two error codes:
P0422 - Main catalyst efficiency below threshold bank 1.
P2188 - cylinder bank 1 too rich.
after reading up on this forum and others, I thought it could have been MAF, but then that would effect bank 2 too? So my gut feeling is that it could be O2 sensor in bank 1, or a defective cat, or possibly a camshaft sensor??
Just wondering if there is anything else I should address......
finally, the seller said it had a slightly noisy chain, so i'd factored that in for a change, but I can barely hear it - so I wonder if its a slightly stretched chain could that make it overfuel as camshaft too open?
Thanks very much in advance. As I said completely new to Mercs, so sorry for the questions. In the past I've spent hours on the Volvo forum helping newbies with Volvo's, but i'm completely in the dark on mercs.
