Talking Gauge cluster repair

My 2001 Z3 Roadster's tach had been very flaky, but not trusting my own skills taking apart delicate instruments, I purchased for $90 a used cluster on Craigslist, had it installed into my Z3, then sent off my original cluster to BimmerOnly in California. The temporary cluster worked perfectly, indicating that the problem was in my tach, not in the car's electronics. BO opened the unit, tightened all the connections, put it on the test stand for a day (I had indicated that the flakiness showed up primarily on hot days; during the winter the tach was fine), then sent it back to me. I had my original cluster, with its perfectly functional tach reinstalled, and now I've got a good working gauge cluster for sale.

The extra unit's odo reads 64,400 miles. It's from a '97 with a manual transmission. Mine has an automatic, so the temp cluster would not give an S (sport) or gear number readout. It works in any Z3.

I found BimmerOnly to be very honest and helpful. He charged for only the time he had the unit actually apart for inspection, then for reassembly.

Flaky z3 tachometer, part deux / tach needle concern

A few days after the [original] worked-on tach was reinstalled in my 2001 Z3 Roadster the same problem reappeared, namely the tach stops working at odd intervals when the ambient temperature rises. A slap of the hand on the top of the cluster brings it back to life. This to me indicates a bad connection somewhere, but the repair people were sure there was no problem, since it worked perfectly on their test bench for a day. I have decided to replace my cluster's tach with the one from the replacement cluster I purchased, the one that worked perfectly in my Z3.

The BimmerOnly tech indicated that a tach will stop working if the voltage drops even a small amount, and that any problem occuring with the original cluster will probably reappear with a replacement unit, since he suspects the problem is with the car's own electronics. I'm in NC, he's in California, so bringing him the car is unfortunately out of the question.

Re: removing the tachometer. My understanding is that the tach's needle needs to be removed in order to detach the tachometer unit from the cluster.

My principal concern: manipulating the tach's needle without destroying it in order to remove the tach from the cluster, and then reinstalling the replacement unit so that it reads correctly. Has anyone successfully removed and replaced their tach needle? Thanks for any suggestions.

Gauge cluster repair

Collected tips for removing the tachometer needle have included:

(1) use two spoons (bowls down) upon a heavy paper disk on the gauge face to leverage the needle off, making sure pressure is above the screw attachments;

(2) use a fork the tines of which were carefully slid beneath the needle, again using a protective paper disk.

After reinstalling the needle. The pointer is rotated clockwise to the end of its travel, then counterclockwise back to the zero point.
