Learning a lot today and wanted to share my info - my SL500 just got past its MOT as its emissions were quite wobbly and kept reading too high.
I 100% trust the special MB place I take my car and the intel I get from them.
So - the 2 catalytic converters look below par and might not be up to the job (they were changed before I had the car it seems)
The air mass came up with a fault a couple of times but the actual values were reading ok in real time?
The car drives beautifully but when I traffic and just moving a few yards it sometimes cuts out and needs restarting - idle seems fine at 600rpm and the M113 engine doesn’t normally suffer with the crank sensor failure I understand.
Where would you start - catalytic converter check at a proper place or replace the air mass sensor?
it’s been a busy few weeks with the old girl !!
