2003 X5 stalled while driving at low speed

I think he's looking for just part of the harness. Junk yard will likely be the best option. It's also a ton of work to swap a whole harness. Sometimes you can just pull just the wires you need out of the loom and re-pin the connectors.

Thanks. I am going to first swap the crank sensor with OEM and then drive the car again. I can't in good faith keep driving the car without at least doing something which might resolve the issue. I need to keep testing. The issue started after I swapped the crank, so maybe it was a shitty one.

I don't really know how big the harness is, it's the one right next to the throttle body. I'm less worried about the connectors and more worried about the wires being brittle or broken inside from 23 years sitting next or on top of the coolant hose. I don't see any pics online that show the box where the wires are popping out from. Maybe the box opens and it's just a housing of some sort. I agree it would be difficult to change

I have a spare x5 with 79k miles, but don't really want to be poaching parts from it. Although it needs to be gone through.

I'll get back! Thank you all. I'm not giving up yet... Engine still has great compression and go, when it's not stalling.

Make sure the connector pins/sockets haven't been abused especially when you get to the crank sensor. You can butcher a pin out of an old sensor or at least make VERY sure that you get the EXACT size pin to check the fit of each socket in the connector when you are at that part.

I can't understand why you are having trouble finding that octopus harness in realoem, I used an old downloaded ETK and was no problem finding it. Anyway, I doubt the wires are as bad as you think but you can always take off some of the plastic tubing and have a look.

As far as the spark plugs, it's not just one bad plug. The coil over plug design doesn't create nearly as much spark energy as the older distributor systems so are a lot more sensitive to having good spark plugs. Mine has done it 2 or 3 times over the years where it stalled out or more often 'almost' stalled while sitting at a light and changing the spark plugs was the answer. The first time had me scratching my head for a while but when it happened again years later I just went straight to the spark plugs. Might not be your situation but something to keep in mind.

Thanks. I looked up the crank sensor I bought, it was Bremi brand. One review said it worked for 5 hours and left him stranded. This started after I swapped it in myself. So I'll swap in an OEM and keep going!

[80stech]

Yeah, car is not going to fix itself!

[Meestahbig]

Yeah. Agreed. Lol. I'll report back after Thanksgiving and more road testing.

FYI...

Bremi is the genuine supplier of speed sensor, ignition coils etc for many
European cars.

Bremi is a very reputable company.

Just stay away from counterfeit stuffs...

I looked into the TIS for the CKP and it doesn't mention shims so if you are using OEM/OE that should suffice.

I'm resurrecting this thread. I'm sorry, I went off in another direction about the idle air control valve, which was not my issue.

That thread is here and I'm not going to post any longer on that one.
