SOLVED - Engine Stubles when cold - with SES
 

This morning, it was colder than normal - about 43 degrees. When I got to the bottom of my hill, which is about a half mile from my house, I stopped at the stop sign, and the engine was stumbling and running rough. Looked down at the gauges, and the SES light was flashing. Put it in neutral and revved it a bit, and it went back to normal, and the SES light went out. Any ideas what this might be? I have a Paeke code reader for my M5, but I don't think that the X5 has the 20 pin connector under the hood.

Your X might actually have the 20 pin under the hood. And it sounds like intermediate levers.

Where do they hide the 20 pin on these? and what are intermediate levers?

I don't know where the 20 pin is, I know some have it in the earlier years.

Intermediate levers are inside your engine. If you ever need to fix it, you are in for a lot of money. Most people just deal with it.

You should scan the codes though. Doesn't peake sell the adapter to be able to plug into the OBD2 port.

20 pin OBD port should be next to driver side shock tower under the hood.

I thought someone told me that its only on the pre-facelift 3.0 though not the 4.4. Maybe they were mistaken.

Or maybe it was non-sport models that had them?

Well, here's a pic form a 4.4. At the top of the pic, there are 4 black caps. Its the left most cap, nearest the windshield.

I think all 2001's have the OBD un the driver footwell. They did away with the 20 pin connector near the shock tower late 2000.

Does the M62 have intermediate levers? I thought the intermediate levers were components to the N62 motors, specifically the Valvetronic system.

I could be wrong.

didn't know about the 20 pin being done away with in 2001.

Not sure about the levers in the M62. You might be right. I keep applying everything V8 to the N62.

Yeah, my 01 4.4 doesn't have that. Its a May 01 production, so farily early. I think they did away with those in late 2000.

Haha and dont worry I do the same thing too, except opposite. For some reason I keep worrying about Timing chain guides on the N62, but some say they aren't there. Then I go to Realoem.com to look up stuff and I see it there. Then I go DOH!!!

I mean, I am assuming something is there to keep the chain in check. Funny thing is, I haven't heard anyone on here complain about a leaking valley pan on the N62's or timing guides.

I checked mne at lunch, and it does not have the 20 pin - it's a 10/00 build. Just remembered that I boiught an OBDII reader for my wifes car a while back. I'll pull the codes tonight and see what it says.

Did a quick search on the intermediate levers, and almost evberything I could find references the N62...

BMW started phasing out the 20 pin connector in 09/1999. Since you have an MY2001 I wouldn't expect your X to have the 20 pin. If you don't have the Peake adapter cable you'll need one in order to use the reader with your X. HERE is a link to the adapter cable.
