I just took my '89 out for a short drive. Was heading down the road when I realized the upshift light did not come on. Then saw that speedo was not showing any speed nor was the odometer working.

First thought was speedo died. Then about five miles down the road the speedo/odo sprung to life and all was well the rest of the drive.

This is the first indication of any trouble with the speedo in over 1000 miles since I bought the car.

I'm assuming it is a problem with the transducer/pickup (?) at the trans. housing. Is this a correct thought? What is involved here?

Thanks,

David

Fausto. I dont know what to say.
BMWdavid. Funny you should say, I have the same problem w/my 87.

I did some searching and checking and it would seem that I might have a problem with the speedometer sender unit mounted on the transaxle. It looks like a fairly easy thing to get to.

I will wait and see if the speed acts up again. If so then look like I have a small project coming up.

I've had similar issues with mine. Also the odo stops working. My wrench says it is most likely the sending unit on the transaxle. Mine is working fine for now, so I'll wait to have it replaced.

Fausto:
I plagued with mental images of you blasting around in the Big D w/ your speedo up and your roof down. Thank god they're not the inverse!
Hows the chip treating you, and what have you done with the pipe issue?
Have you breezed by RUF?

Speedo issue (other than Faustos!) I have the same report re:sensor. Let me know if yours is cured by replacing same

These are extremely easy to fix. You will have to take the access plate off on the rear tunnel inside the car (remove 4-Phillips screws). When in there you will see a dark grey (if I remember right) twisted strand wire which will go from the rear of the car (on the side of the transxle) up through the tunnel to the back of the speedo. I recall too that they put a two-pole quick connect on this thing so that you will only have to route the new sender's wire(s) from the tranny area into that access area. Then simply disconnct the old one, and plug in the new. The sender is secured with a screw I think. Sorry,--it's been awhile for me.
