Hoping anyone can help in some way, here’s what’s been going on with my E60 530d, Last week I was driving at around 35mph light throttle and the car suddenly felt like it couldn’t make its mind up about what gear to be in, it harshly changed gear like hitting a bump in the road, I thought well that was odd. About 300 yards later, I’m driving at around 40mph and suddenly realise it’s revving in neutral, knocked it back into drive after slowing down and continued. Got to some traffic lights and it stalled, started straight up again and drove on, about 300 yards later I get ‘fault in drive’ appear on the dash, followed by the car basically not wanting to get out of low gears and changing down instead of up at 50mph, the manual select did nothing, eventually after letting off the accelerator it changed up and drove around 20 miles home without issue.
The fault didn’t return until now around a week later, started the car and it died, started again and it died again, eventually got going and got to where I needed to be and turned it off, 5 mins later it would not start at all, cranking for a long time and no joy, it did eventually start but I thought it was done for. Now another few hours of driving with stops and starts and you’d never know it had ever happened 🤔 OBD scanner picked up the attached codes in the pics, it’s been mapped by the previous owner apparently.
I removed the EGR (bottom N/S bolt was a pain to get to) and I will attach pics, there was oil in there, it didn’t look absolutely caked to the point of where it’s the culprit to me?
also to add, checked the voltage while running and it’s usually 14v on the nose most the time, however the coolant seems cold, it sometimes drops to around 65c on a long downhill, EGR stat?
it’s getting much worse now, it cut out 4 times in 9 miles earlier, straight to neutral and cut out after revving up with reduced drive,


it seems that when I do the gearbox reset with the accelerator pedal down for 20 seconds it’s ok for a while but maybe nothing to do with it.

You could have a vacuum leak.

thanks for the reply, what’s the best way to check? Start by plugging the small vac hose on the EGR? Would that cause all of that stuff to happen? The stalling and gearbox going really weird?

The best way to check for a vacuum leak is to perform a smoke test.

When my car had a cracked crankcase vent hose, it was stalling and doing all kinds of weirdness.

Update, new crank position sensor on 900 miles ago and 🤞🏻

i have the same issue but no juddering, it just cuts out but starts straight back up and can then drive beautifully for weeks. I also had dpf egr and a pressure rail fault code. New dpf and egr fitted but still randomly cutting out, now fault shows 43E2 throttle valve.
did the crank sensor clear your throttle code?

No the EGR code persists, probably needs blanking to be honest when I get round to it
