The problem is that when i search by part number 51 21 7 202 144 it shows me a lot of different BMW models that fits on [Ebay], however, some are with 5 pins and some are with 7 pins. My plug is with 7 wires, however, I did not look at the lock damn it and I closed it off so that I could use the car.
Yes I am going OEM second hand and I am not planning to keep the car for longer [I think], it just does not make sense anymore to keep it, spending a lot on it and things keep going wrong no matter how much I take care of it. It is 16 years old, and these cars were not built to last that long - I know cos I worked in the automotive industry. It needs a new headliner, it has a big oil leak now probably the sump, it needs all front arms, wishbones..etc at the front...that alone will cost min £1,500 to do all properly.
