E30 325i black smoke/oil pressure

[MyDirtyThirty]

Hi there, sat there writing this in a pub where my 325i auto is stuck in a car park. Feeling really pissed off as just put my car through expensive MOT, took it out to celebrate it running and it's totally gone nuts.

Oil pressure light seems to come on at low rpm, and idle. Checked the level, seems fine, but the oil was dripping off the dipstick so seems very thin. Anyway, took it out, ran fine, stopped at a pub, fine.

Got to a junction and the thing seemed to just stall while I was waiting. Started up again fine, then when I was driving seemed a little juddery. Pulled into a car park and it really started juddering, spluttering, and a bit of black smoke started to come out of the exhaust. No smell other than exhaust fumes. I tried to leave by reversing out the space, but it was not happy idling, and the MPG gauge started flapping back and forward like mad, and my car died. Turned the key few times, nothing. Still out there.

Had the car a year and feeling really demoralised. Is this sounding like a big fix? Is this something to do with the oil pressure?

Interesting, thanks. Yeah it starts for about five seconds drives.. Then dies. Wait five seconds, sparks up again, juddery, I put my foot down, dies. I can't move it. Is this what you'd expect with this kind of injector issue? Is it gonna cost me?

All good ideas. Thanks all! Interesting to read all this. I would have a look at it but it had to be left there in the end- it was towed away today and going to get the verdict tomorrow. It's bloody thirsty so hopefully something will be sorted. I love that car too! There's so many little bits up with it though. Now the convertible top has broken...
