Engine Warning Light and flicking idle revs

RichDM5 · 06-25-2018, 07:51 AM

Hi all,

Engine warning light came on solid orange the other day and since then at start the idle revs (after cold start) flick up every second or so as if im lightly tapping the gas pedal.

Looked at the codes and have P2243 (Oxygen sensor?) and P128E01, P12B505.

Car is booked in next week for 4th year oil and spark plugs and under extended comprehensive warranty. Anyone know if i should get it in sooner or just wait - nothing long distance planned - maybe 50 miles in the week.

I would phone BMW mobile assist and ask them

Agreed. Get them to tow it and force their hand. Aim to get it back fixed, serviced and cleaned and then you can get back out enjoying it during this awesome weather.
