Recently the odometer stopped working on my 1987 560SEL, just before the car hit 340,000km. This is a pretty common problem on the W126. I had to repair both my old 300SE and my 560SEC. The issue is the small gears that turn the odometer. They are made of a very soft plastic and after 30+ years, the teeth break off. This repair is...
Late last year the power window on my 1987 Mercedes 560SEL stuck in the down position. I lowered the window to exit a parking station and the window would not go back up. The first test I did was to check the switch. This would have been the easiest and simplest repair. It is very easy to swap the plug on the front and...
For years the W116 has lived in the shadow of the W126. The W126 is often lauded as one of the best cars Mercedes-Benz ever made. Under its skin it can trace its lineage back to the W114 models of 1968, but the styling was fresh and modern and it was light years ahead of everything else on the market. Today,...
A couple of months ago an eagle eyed viewer of my Instagram feed asked my why my 560SEL doesn’t have a Hirschmann Antenna. Given how original the car is, it was a good question. I had never really noticed what antenna the car had, other than it worked. Since I have the original Becker, I really should have the original Hirschmann Antenna...
Previously, I had installed a Becker Mexico 1402 Cassette in my 1987 560SEC. This is a very similar model to what it left the factory with. My setup looked factory, but was running a hidden Bluetooth FM injector, amplifier and USB charging ports. After driving around for a few weeks, I realised I needed to make a few changes. Overall, I was...
I am currently in the process of installing a period correct Becker Radio in my 560SEC. In part 2, I had the system up and running. The final task was to tidy up the installation and re-install all the trim. The first step was to properly organize and tidy up the wiring. I wanted a neat install, and to hide all the wires out...
In part 1 of this series, I had begun installing a Becker Mexico 1402 in my 560SEC. I had planned out my install and done the core wiring for the Becker itself. Today, my goal was to complete the wiring of the ancillary components and test the system. I decided to use two X30 harneses for the install. I had four available plugs on...
My 1987 UK Market 560SEC was originally sold with Becker Mexico Cassette player (option 251). I’ve been planning for a while to re-install a period Becker radio, with a few of my own upgrades. My first task was to research the radios and purchase a suitable unit. I ended up purchasing two radios, Becker 1402 and Becker 1480. As the skills and parts to...
I’m currently planning to re-install the Becker Radio in my 1987 560SEC. At the same time I will be installing a small amplifier, a bluetooth FM Injector and a couple of unobtrusive USB charging ports. The second generation W126 wiring harness provides a factory way of adding additional accessories. This is the X30 power block. Up to 8 accessories can be connected using factory...
The S-Class is probably the signature model for Mercedes-Benz. Personally it’s what I think of when I think of the brand. When I think Porsche, I think rear engined sports cars. When I think of BMW its sports saloons with an inline six. For Mercedes-Benz, it’s the S-Class. Throughout the years the company has seen other halo models come and go, such as...
I recently attempted to take my 560SEL on a Mercedes Club night drive. On the way there, I experienced a soft brake pedal and a very hot drivers side rear wheel. I had an issue with a soft brake pedal on a mountain road back in 2020. At the time I thought I had solved it as I removed the aftermarket brake dust...
The second generation W126 controls ignition timing from the EZL. In most countries, Mercedes-Benz provided a knob to adjust the timing based on the petrol that was available in your area. This knob is present on my UK delivery 560SEC. I immediately turned the knob up to 98 octane petrol, as that is what I use in the car. In markets like Australia and...

I purchased my 1989 420SEL about two years ago and have been busy doing a lot of work to the car to bring it up to my standard. My most recent job was to inspect and replace the W126 parking brake shoes. The parking brake was not holding the car, even after I adjusted it. The Mercedes W126 uses a separate set of drum...
Last week I fixed the outside temperature LCD on my 300SE. Today it was time to fix the 560SEC outside temperature display as well. In my previous post I covered the details of where I purchased the replacement LCD panels. This same repair should also work on W124 and W201 models of the same vintage. I understand there are minor variances, and that the...
For the first time since I have owned the car, my 300SE has a working outside temperature display. Not only is it a useful feature of the car, but these small fixes can make the difference between the car seeming nice or a bit of a jalopy. The W126 Outside temperature LCD repair is really easy. It should be on the radar of any...
The W126 outside temperature display was standard in all Australian delivered series 2 models. The little LCD screen is not really compatible with the Australian sun as most of them start to bleed and become unreadable. My 300SE and 560SEC both have unreadable LCD screens. The 560SEL, which was garaged all its life still has a good screen. Buying a used one is not...
