Hi all, I’m new here, but hoping I can get more involved now I have an e63! I picked up a 2013 facelift w212 around a month ago, loved every minute of it. It has had a few tweaks like cats and resonators removed and some mapping and is currently at around 750bhp. Anyway onto my issue...the car has full MB service history and no service was due but the garage I bought it from performed their own service on it which was filters, oil change and air filters now I have already had to replace the air intakes as these had completely collapsed and got sucked right upto the filter I was pulling them out like a clown would keep pulling hanky’s out of his pocket. I notice this more so wen I pull to a stop off gas completely, a fair bit of smoke sometimes can be seen coming from the rear, more so if I have it in sport or sport + I would say, it is strong smelling. I managed to get in touch with the previous owner and he said it had never done that with him so my concern is that it either has too much of or the wrong oil in from this last service? Does any one have any ideas what it could be? I was going to ring MB today to get it booked in for full oil and filter change ASAP. I am grateful for any help on this, it’s my first Mercedes and am looking to learn/expand my knowledge along the way. Cheers, Scott.
