Cheers Wammers. I had read some threads and had a suspicion thats what it was. I'll let you know the idle speed later when I'm home.
Do I have to take off the timing chain cover to get at the pump?
This sounds like the worst thing that could have happened. I'll press on regardless though.

No you will need a sprocket holder to remove the pump. DO NOT remove pump unless sprocket holder is in place, only remove pump with engine locked at TDC number one firing.. You will also need special tools to time it on refit.
Looks like 750 to me it should be 750 + or - 50. But stalling when put in gear is usually a quantity control servo problem. The noise like a chain slapping does not sound good. Unless you know it's not that.

Thanks for looking Wammers, I appreciate the input. That noise is completely new, never heard it before this evening.
I am reading a thread you posted in on the similar subject, here - https://www.landyzone.co.uk/land-rover/bmw-diesel-timing-chain-tool-p38-diesel.306357/
Sounds like bad news. Taking the head off is a learning curve I could do without.

Wonder is it related to the pfffff / dump valve noise I heard at 4000 rpm.

@wammers, do you remember when I had the noises from mine. You'd asked me to unplug the QCS on my pump while it was running. It made a similar but more constant noise when unplugged. Along with the stalling in gear and that noise being present. Could he test the QCS before pulling parts off?
Maybe i told you to unplug timing solenoid. You cannot unplug quantity control servo if that is what you mean by QCS. Feed for that is in the main plug to loom if you unplugged that engine would just stop. When pedal pot is below 9% ECU takes over idle control, when it sees engine rpm drop or rise via CPS it increases or decreases fuel via quantity control servo to compensate for high or low readings from CPS. It then maintains 750 +- 50. If car is put in gear, load is applied and revs will fall, ECU should then compensate by increasing fuel via quantity control. If pot is worn on control servo it loses contact with the ECU so no fuel increase takes place and the engine stalls. Sometimes slightly increasing idle rpm with such as Nanocom can forestall the inevitable for a short time. But a reconditioned pump will be needed eventually.
Don't want to alarm you but that sounds to me as if one of the chain tensioners has broken. Sounds like a chain slapping, that would be my guess at this stage from what i heard.
Thanks @wammers, ooer that doesn't sound good at all..
Hopefully that isn't the case..fingers crossed.
The timing case cover can be removed without removing the head but you need to know what you are doing. You will need several special tools to do this. This is the main part of what you need and at a good price if sale is still on. http://www.sealey.co.uk/PLPageBuilder.asp?id=20&method=mViewProduct&productid=14033

Okay I'll proceed with that option. I can buy the tools. If I mess up, I can remove the head.
I would like this engine to get the car through an MOT and road legal, which it is not at the moment.
Once it's on the road I'm going to start collecting the bits for an M57 swap.

If you fit the M57, budget for the GEMS V8 RAD.
Does it have that mechanical compressor thing running off the crank? Worth slipping the belt off and see if it is that venting?
