Hi guys,
I attach a video to explain the behaviour The car runs always fine but after some time and when restart this happens. Car is an x3 n55 engine I did already - eccentric shaft and sensor and engine for eccentric shaft - camshaft sensor - ignition coils and spark plugs There are never errors in the error log. Can it be the high precision pump ? I doubt it as the car runs cold fine and starts perfectly … Glad on any tips Have this issue since july and invested 4k :-( Close to sell the car Cheers Thomas Edit: sorry i put into wrong category if admin can move to maintenance and issues thanks |

I did an MHD log run! My suspicion is now lamdba …. What do guys say to a lambda afr value of over 200 ? Look how this is going up. Behaviour is in the car that the car stops … accelerates again and has a weird and no proper idle. Thoughts ? Does this point to a lambda issue ? |
