Apparently, I got the TIS from some software pirate on eBay. One disk was supposed to be te TIS for every BMW model from '88 to '98 or something like that and the other 2 CDs are the ETK for all the models. It's probably the 20th derivative copy from the original and is suffering from de-evolution. I emailed the seller for a refund or better disks.

Lowell: What is the final stage or the nebulous "#5"? Are those addresses on the DME, underneath the cover? I will check it out tonight if the CPS is working well. Now I'm wondering who told me the starter was up front.

I will get to the CPS connector tonight but that means I have to remove the manifold. Thanks for the pictures, especially of the connector but I think the location picture is inaccurate. The wire for my sensor disappears under the intake but the picture looks like it should be on the passenger side. That would be easier, but I don't think I'm that lucky.

I guess replacing the sensor means removing the engine fan and clutch?

I hope this solves the problem. I'll write tonight after I test the CPS and I'll order the part for a big victorious repair on Monday.
