Thanks. I appreciate your reply Jon. I’ve had a tough time at several points over the past week. I think I’m going to head over to Germany for his service next Tuesday.So sorry for your loss. I think many of us have been fortunate enough to have met a Thomas in our lifetime and are the better for it.
Funny you mention DDD, when I followed your expert HOW-TO on the 126, I noticed the lower right corner of my case has some DDD. This cluster case is one I purchased when I got the car as the one original to the car was showroom perfect. It was removed and put in climate controlled storage the first week I got the car to preserve it.During March, I've had two business trips where I've flown out of Washington Dulles airport. It's a 150-mile round trip each time I go to Dulles and come back home.
Went to fill up the E500's gas tank today, and I noticed when I got home that the odometer hadn't changed from where I had recorded it at the gas station to update the fuel-up into the Fuelly app.
So, finally after 150,800 miles, it seems that the odometer gears have given up the ghost, around 150 miles ago by my calculations per the last fuel-up in late February. So, my next job will be to replace the bad odo gear(s). Fortunately I bought a couple of sets from Garagistic about 10-11 years ago, and conveniently had them in my garage tool chest, sitting in one of several drawers containing my collection of MB special tools.

I also need to replace the headlight switch, of which I've had a brand new one for the past couple of years, but haven't bothered to do the job.
Also noticed that my front struts are now totally shot (they are originals as far as I know), so I will replace them too. Front suspension is REALLY rough when taking bumps (speed bumps, frost heaves in the road, and so forth). I have new factory MB 500E struts (with the internal limiting springs) in my parts stash, as well as new MB buffers and boots. I will also do the upper strut mounts, though the current ones don't have any cracks.
So, some maintenance is coming my way soon.
Coincidentally, I noticed that my E500's instrument cluster has a Stage 0 case of DDD on the inside. It's BARELY visible and not nearly at the point of needing remediation, but I will watch it, and when it hits stage 1+ or 2-, I will have to pull the cluster and take care of this. I won't let it get to Stage 3 or 4 (terminal DDD).
Here are some close-ups of my cluster, after I re-installed the speedo in the center. You can see that the DDD is Stage 0+ / 1-, and not at all bad at this point in time. But, it will relentlessly advance in the coming years, no question. Accelerated if I still lived in Houston humidity.Funny you mention DDD, when I followed your expert HOW-TO on the 126, I noticed the lower right corner of my case has some DDD.

I had my speedometer rebuilt by Palo Alto Speedometer in January and had a good experience - although expensive.Yep that is where the 124 is showing DDD on my spare case in use. Still nothing on the case original to the car that is in storage.
I think Jouser currently only has 124's in his fleet with mechanical speedos... would be interesting to know what Palo Alto did, and what it cost!When you say rebuilt, do you actually mean the gears or the electronics specific to the speedo gauge or the stripping of the vulcanized coatings of the cluster case itself?
Took the E500 out again yesterday for about a 10-mile run to do some errands, and everything is working excellently with the odometer and trip-odo. So I'll chalk this one up to being fixed. I need to do the headlight switch. Maybe I'll have the motivation to do it after work today.
Re-installed everything and went out for a three-mile test drive. Everything is working A-OK with no issues. Odometer and trip odo are all back to normal operation. Glad I had a set of new gears in my parts stock (I also recall replacing a gear on my 560SEC some years back, so I also had some remnants from that gear kit).
Time sure does fly, I have the invoice from October, not January...I think Jouser currently only has 124's in his fleet with mechanical speedos... would be interesting to know what Palo Alto did, and what it cost!

I had ordered a few spare sets of Garagistic odometer gears recently, which arrived a couple of weeks back. They are safely in my stash of spare parts for when they will be needed in the future.Took the E500 out again yesterday for about a 10-mile run to do some errands, and everything is working excellently with the odometer and trip-odo.
