If it's just a simple busted gear, yeah, fix it yourself. Otherwise it may need the attention of a professional. My 1987 300D speedo trip odometer was acting up for a long time and finally died - after resetting it would 'click' at 0.9 miles, and not roll forward. Continual resetting over many miles might, eventually, get it counting properly again. I sent it to Overseas Speedo for repair, and it came back doing the same thing. I sent it back a second time, they spent more time on it, but it still does the same thing! I gave up, got it working (after a bazillion reset cycles), and just don't touch the reset button anymore. I'm toying with the idea of changing my rear axle ratio anyway, which would require a new/different speedo, and I figure at that point I'll get one that WORKS. Otherwise I may send it in to a different VDO repair shop and see if they have better luck fixing whatever the problem is.
YMMV, etc... :) -Dave M. > ------------------------------ > Date: Mon, 2 Jan 2006 20:02:03 -0600 > From: "Nick Wellinghoff" <[EMAIL PROTECTED]> > Subject: Re: [MBZ] Rebuilt Odometers/Speedometers > > If you just need to rebuild your odo don't waste your money sending it > someone who is just going to replace the one little plastic gear in there > that breaks over time.
