best solution for bad c191

[free]

I am pretty sure my C191 connection is still giving me problems. I have cleaned it numerous times, but the symptoms have returned.

Is there a way to replace it? I can't find a replacement for sale anywhere. or should I just bypass it by splicing all the wires together?

Also, how does the upper part of the connector come off the bracket that holds it?

thank you!

Please? Does anybody have any suggestions for help with this? I have seen enough threads about people having trouble with this, but I haven't seen much info on any fixes except for "cleaned it and works great now". I would really like to make a permanent solution for this!

THank you!

put some dilectric grease, like sil-glyde in there and your probnlems should go away for a LONG time

If there is evidence of serious corrosion of the pins/sockets or wires, the cheap fix is to splice the wires (solder & heat shrink tubing). The next option would be to splice in a better C191 from a used harness (or just replace the harnesses with ones in better condition. The expensive fix is to replace both harnesses with new parts. I think both halves of the connector may be available from BMW. The trick would lie in figuring out what the part number is.

Early cars (up to 8/87) didn't have the C191 connector, but then they also had separate connectors for the injectors. I don't know if you can get the connector rail through the manifold if you splice out C191.

I do have dialectric grease in the connector now, and have problems when it gets wet. I have drilled a hole to drain the connector. The throttle body is not leaking. But washing the car, driving in rain, etc. causes problems.

I could definitely see a problem if I splice the connection, because of the injector connectors. I don't think I could get them through the intake manifold.

I did go to a few salvage yards the other day looking for a connector with no luck. Will have to keep looking.

Thank you for the replies!

My c191 was corroded and a couple of wires were hanging by a thread! I spliced mine together and have not had a problem since. Actually, I soldered on the male/female connector to the wires, connected them and then heat shrunk tubing over the connectors. Cover all that mess with the large plastic tubing and you are good to go.
No problem with fitment through the intake manifold, but then I did the work with the injector harness already attached. Remove the throttle body, etc. and you will have plenty of room to work.
