So you can buy just the CID sensors from worldpac? I believe mine just failed on my factory beru wires and need some.
I swear, my cars are like a girlfriend.
Sometimes its a rough ride, sometimes its smooth motorin'.
Sometimes she doesnt like how i treat her and sometimes i dont like how she behaves.
BUT at the end of the day, she loves it when I am inside her.
. What spark plugs are you running? The original plugs had 1000 Ohm resistors. Almost all new ones are 5000 Ohm or more. The plug wires have 5000 Ohm resistors in the plug boots, so that gives 10k Ohms. Try putting NGK BKR6EK R1 plugs in the # 6&12 positions. The other thing to check is the DK's (Throttle bodies). When the armatures and brushes get all gunked up all kinds of strange things can happen. Be very careful if you are thinking about complete disassembly to go into the gears, as if you do not get the resistor wiper arms back in perfectly aligned you will have similar problems, and Trans failure codes LHM and the EML light on in the dash. Good luck!
I use the Bosch Copper F7LDRC in my M73. Yep these are 2 heat ranges cooler than the stock plug F9LDRC but I also have a 3.23:1 diff gears and I anticipate a cooler plug is good for the increase in RPM and reduced engine load.
Over the years with the modified engines that I have had the most difficulty with Pre-Ignition the Bosch Coppers have always solved the problem so I have stuck with them!!
These plugs are OE on the M60 & M62, V8's with the same coil as the M73/V12.
These plugs are the same as the F7LRC & F8LRC (1000 ohm resistor) except they have a dual ground electrode and I like that feature!!
See the attached Spark Plug chart for all BMW applications.
Old thread, but I just read in the German forum about a case where someone changed on his M70 distributors, rotors, spark plugs and ignition wires on cyl. 6 and 12 and used the re-old donuts.
Then he had trouble. Engine starts, runs short time with increased RPM and then dies.
EML lamp goes on with ignition on and then goes out again as it should be. Diagnosis faults: fault ignition cylinder 1-6 and 7-12.
That was 2 weeks ago.
Today he fixed it. He noticed that he installed the cylinder identification sensors/donuts/pulse generators on ignition wires cyl. 6 and 12 the wrong way. Turned the donuts the correct way and engine runs smooth.
Pulse generator 2 12121725020
So make sure the donuts are working and installed the correct way.

Is there a way to identify direction Erich?

Friend had same sort of problem a while back, motor would start and then died shortly thereafter. He'd brought it used from out of state. I had a suspicion after listening to the motor start and die a few times that not all cylinders were firing. I took a look at his ECUs and EML and found they were from a 3 series! Popped in a spare set from an M70 and the car fired up and purred like a kitten. Turns out original owner sold car because it kept shutting off. Very happy the issue was that easy to resolve!
no marks on the original ones, if I remember correct, original Pulse generator 12121725020 https://www.ecstuning.com/b-genuine-...e/12121725020/

DV8OR mentioned on the E32 forum here: I will go check but if I remember correctly the OE BMW one are symmetrical and I did not see any type of mark as to direction. The aftermarket one that I had was larger on one side like the pic you posted but if you are having issue it might be worth a try to flip it.

Comment on the German forum:
Die Einbaurichtung ergibt sich durch die Bauform des Donut. Die Bohrung ist innen leicht konisch und geht auf der Seite, an dem man die kleinen 3 Nasen sieht zusammen und geht von der Seite aus nicht auf das Zuendkabel. Somit ist dann die Seite mit den kleinen Nasen in Richtung Verteiler und die offenere Seite mit dem Radius in Richtung Zuendkerze.
translated:
The installation direction is determined by the shape of the donut. The bore is slightly conical on the inside and get's on the side where the small 3 noses are located smaller in diameter and will not fit from this side onto the ignition wire. Thus, the side with the small lugs should be in the direction of the distributor and the more open side with the radius in the direction of the spark plug. see here also the pics from Sean which is converting a M30 wire set for a M70

what is the p/n of the female connectors for the CPS and cylinder identification sensors for the M70 engine, these are part of the engine wire loom, the counter parts where the male CPS and donut connectors go in. 2 white and 2 black 3-pin connectors/plugs . In ETK for E31 there is nothing shown, the E32 ETK shows under engine electric a 3-pin plug which could fit. Plug housing 12521706068 3 POL. NLA. google finds as replacement respect. old p/n : 12521706096, 12521706068, 12520492991, 12521358472, AMP 827578. Here a drawing from front of the plug http://www.e32-schrauber.de/bmw/date...or_Stecker.png
Did someone already replace such a plug and can confirm the p/n? On my website there are some good pics from page 22 - 26 of these plugs. http://twrite.org/shogunnew/files/fo..._Refurbish.pdf

From my 5/95 Electrical Connector Repair Kit Listing - original 3-pin connector P/N: 90-88-6-706-096 Plug Housing 3-Pin with release device (black)
The 90-88-6 on these P/N was updated to 12-52-1.
I anticipate the 3-Pin plug housing will be the 12-52-1-706-096.
Should be available at the dealers.
edit:
I just checked my parts bins and I have the 12-52-1-706-096 and it is the AMP 827578, 3-pin connector.

Thanks for the confirmation, 12521706096 3-pin , Supersession(s): 12-52-1-706-096; 12521706068; 61131358472; 83300492991, seems to be a fault in the ETK, not listed at all for E31, used on many other cars in various places. Part Cross-reference 12521706096 Plug housing From: 06/01/1986 To: - , Supersedes: 83300492991 (09/25/1996 — 08/13/2007), Part 12521706096 was found on the following vehicles: E30, E36, E12, E28, E34, E39, E24, E23, E32, E38, Z1, Z3 E36

Yep, BMW can build them, but once out of production they can't tell you what's in them!!
I also see 3-pin Plug housings: Late model vehicles?
3-POL 12521732596
3-POL 12521732597
But I don't think those are what your looking for.
Since my first BMW I owned in 1990 (E34, M5) I knew BMW had problems with parts not in the parts catalog (microfiche - back then) and parts listed but not assigned to the series; even though the part was in the assembly.
Through the years, I have amassed all the Paper & CD parts catalogs, tool catalogs, Retail Price List, Service Bulletins, Service Manuals, ETMs, Training Manuals, TIS, DIS, etc, etc and/or what ever I could talk the local dealer parts counter guys out of (at some point they would give me all their old revisions) just so I had a fighting chance to identify the parts I needed to keep my BMW's original and new as possible. The first CD ROM TIS, ETK's, Technical Documents & Training Manuals (when paper phased out) was very expensive ($300 deposit/CD ROM & $50/revision) but worth every penny, as a DIY'er.
Good luck...
