Re: Injectors 4,5, and 6 not working, euro E12-based 1981 635CSI with Motronic (late 1981-82)
Well, on an '84 injectors 4-6 are grounded by the ECU at pin 15 using the Brown/yellow tracer wire with a splice presumably nearby in the injector harness. My guess either the ECU or the wire. Actually the splice or ECU connector, rarely does a wire go bad. This assumes your car is similar enough to...

Re: What did you do to your E24 today?
Washed of yesterday's road grime. It was still damp early yesterday on the drive to Sebring. A small cold front passed overnight leaving very nice weather all day. Met up with a couple friends for the drive. Attended the SVRA vintage, GT America and Trans Am races. There is a large car show there as...

Re: Heater blower transistor failure mystery...
Air conditioning? What is this sorcery of which you speak? (Mine has never worked in either E24....that's why they get little use during the summer) . I got a cool sorcerer's hat and wand from ebay and made mine work. In Florida. In August. All it takes is time, patience, and of course money. It is...

Re: WTB Instrument Cluster housing for 88 M6
I'll try to pull it out tomorrow and confirm condition. There are no cracks. The difference between the failed glue joint on both your housing and my cover may make it interesting to get a nice clean new joint interesting. Hopefully the joint will not be too visible. I can tell, for example, where t...

Re: WTB Instrument Cluster housing for 88 M6
I have a parts cluster with a loose lens. I believe it is in decent shape. I want the cluster, but may part with the lens. I'll pull it out and check the condition.

Re: What did you do to your E24 today?
Today I drove it, but that is not the point of posting, is it? Recently I decided it time to address the wonky speedometer.

Re: 1984 633CSi Rises again!
It probably won't mean anything to your exhaust leak. I repeatedly had to repair a leak where my turbo down pipe met the exhaust. It is a flat round four bolt flange. Tired of making the repairs I decided to fix it once and for all. First I cut a new gasket out of soft copper plate. Then sealed it o...

Re: Moving Power Seats on the Work Bench for Cleaning/Maint
The buttons work in conjunction with the seat controller. They wouldn't be necessary to use either to run the seat motors on the bench. The motors are permanent magnet which means by reversing the polarity the motor changes direction. Page 159 of my '84 model ETM, attached, shows the motor wire colo...

Re: 1970's Cars
I'm curious about early car brakes as I have zero experience with them. Can the E12 based cars upgrade brakes from the BMW parts bin? I did the 5 series front/7 series rear with an E32 master years ago on my '84 (non ABS BTW). Is something like this possible?

Re: Odometer Gears
I just reassembled my cluster after a contact cleaning to hopefully clear up a wonky bouncing and pegging speedometer. I removed it again when I drove it and had on odometer. I guess I have been on borrowed time for quite a while. Opened up the speedometer and sure enough the motor gear was in three...

Re: Power steering pump misbehavior
Pump cavitation is caused by a restriction not allowing sufficient fluid flow into the pump. I didn't see mention of the filter condition, nor of the condition of the suction hose. When a pump cavitates it pulls a vacuum that can vaporize a fluid causing bubbles. When the pressure changes and the va...

Well, I had a detailed post written without being logged in. Lost it all in the process. Doh. I am looking at my ETM for an '84 US model, relevant page attached.

Intermittent electrical, my favorite. Is there a sarcasm emoji? Do you have an ETM? It is a necessity for troubleshooting. It sounds like connection issues somewhere. Bad grounds can do all kinds of wonky things. Also lamp sockets could be loosening up over time. I'll try to remember to look at the ...

Sure, the AC compressor can be removed. All the AC components can come out as a matter of fact. There is no connection between heat and AC. Curious why?

Maybe, but wouldn't a vacuum leak show up as a rolling idle due to unmetered air?
That is my recollection. Could be wrong as my Motronic has been gone for a long time.

My injector O-Rings appear to be 13 64 1 730 767, 7.52 x 3.53 mm.
Strangely when I went to check the size on a different computer this morning I could not get to the same page. Using my VIN or entering the info did not bring up the page I linked last night. No parts fit my car I was told. Odd.

Even if not an issue it is worth the effort to eliminate the possibility. It sounds, by your list, that you have some instrument cluster issues. Since you expressed c...
