I’ve owned my 250SE almost ten years and always had a mind to replace the cheap rubber mats with Cocomats. Today I fitted the Cocomats I bought as part of a group buy with a few friends. I also purchased a set for my 560SEC and went into a bit more about the purchase there. For the 250SE, I went with #53...
I had recently noticed that the battery on the 250SE was not in good health. The battery disconnect switch I built a few years ago has a battery health indicator included. Even when connected to the trickle charger it was showing orange. I also noticed that the trickle charger would sometimes go into error mode. My battery tester showed that it was well...
After all the recent work done on my 250SE, I wanted to take it for an extended test drive. Its had motor and transmission mounts, front crank seal, re-sealed power steering pump, injectors, distributor cap and rotor, points, condenser, coil, plugs, alternator, voltage regulator and more done. The spark had been quite weak and the engine was carboned up. The Mercedes-Benz club have...
On the way back from the September night drive my 250SE stopped charging properly. I was able to make it back home about an hour on the battery. Even using the headlights the 250SE does not use a lot of power. As it happened, a friend of mine had a rebuilt alternator that was correct for my car. He drives a 280SE 3.5 W108...
Over the last couple of months I’ve had issues with the M129 rough running in my 250SE. The car was hesitating, idling poorly and just not running very well. I’ve done a few things over the last few months to improve this situation. One of the first things I did was change the injectors. The stutter when accelerating and hard starting when hot felt...
After using blank plates as a way of attaching NSW Historic Plates on the 450SLC and the 560SEC, the adapter I fabricated for the 250SE was looking rather shoddy. I made it myself out of aluminium. I used thin aluminium to make it easier to cut. The thin aluminium bent easily and now had creases. I liked how using the blank German plate filled...
A couple of weeks ago I installed the Classic Auto Sound Becker Tribute Radio in my 250SE. I’m really happy with it, it worked really well on my recent drive down to Canberra. One of the only things I thought could have been improved on the radio was the buttons were unlabeled. The real radios had LMKUU buttons. Classic Auto Sound, who build these...
This weekend I traveled to Canberra for 2019 ACT German Car Show. I’ve been to this show a few times before (2013, 2015, 2017), but this is the first time I have formally entered a car. In prior years I have driven down on the day and arrived around 11ish to see the show for an hour or so. This year I decided...
Today I completed the install of the Classic Auto Sound Becker Tribute. In the first part, I removed the old Clarion, and installed the the Retrosound wiring harness. I also tested the radio and it was working fine. The new radio looks great and is a huge improvement over the Clarion CD player. Installation Step 4: Convert the Becker Tribute radio to DIN At...
I have been wanting to change the radio in the 250SE since I have owned the car. It was a basic Clarion unit that looked totally out of place. The dashboard in my car has been cut to DIN size, meaning going back to the original Becker wasn’t really an option. Unfortunately many W111’s had their dashboards cut up in the 70s...
Most Mercedes from the mid 50s to the late 60s had a similar set of controls for the heater. There are four horizontal levers controlling the amount of heat and the direction of the air flow. At least on the W111, the lever on the top left controls the amount of outside airflow. The top right controls the direction of the airflow. The two...
The OzBenz forum is one of the online resources I use to maintain my Mercedes-Benz’s. The forum has evolved over a 15 year period, starting with the Mercedes Veterans mailing list, branching off to the OzVets mailing list. This became the OzVets forum and then later the OzBenz forum. I joined very early on and found this a great set of resources to...
I like to fit a battery disconnect switch to all my cars. It ensures the batteries don’t run down and prevents fires. Fires are a real risk from cars with old wiring. I had put one of those cheap on terminal switches on the 250SE when I got it a few years ago. Of late it had been playing up and was difficult...
When I last replaced the battery in my W111, I was unable to fit the correct sized battery. In the end I fitted one smaller than I would have liked, but it was the only one that fit into the mounting frame I had. I knew the mounting frame was not original to the car as the previous owner purchased it on eBay. ...
The Sydney German Car Show 2017 was held today and as usual it did not disappoint. A great selection of Mercedes-Benz, BMW, Porsche, VW and Audi’s were on display. The only downside was that aside from the Micro cars, there was no representation from the niche German cars. There was also only one pre-war car. This event has really grown...
I had a couple of small jobs on the 250SE I had been meaning to do for months. Since the car is to be displayed at the German Car show, it seemed like a good time to do them. One of the hubcaps was in poor condition. I had another set of used hubcaps painted almost a year ago now. However, I...
