[jackmok]

Hi bros, sis, yest my car encounter a bizarre technical problem. I was trying to overtake a lorry n I full throttle. I heard some sound like back fire "poop poop" n the instrument cluster for gear pop up a sprocket wif exclamation mark in it. N the transmission becomes v jerky every gear change. When it comes to stop n go, my car will stall. Hwever I managed to slowly drive back home abt 10km away wif more than 5 stalls at trf lights. Iuse my code reader and these showed these codes: P0101 powertrain, mass or vol air flow circuit range/performance problem

P0700 powertrain transmission control system (MIL request).

Anyone encounter or know whats the problem?

What did the WS say since this was over 3 months ago ?

Those are generic obd codes. But it seems your gearbox got problem. If you can pull the bmw specific codes - that would help better.
