I’m back in the USA for an annual conference I attend. I normally have a free day before it starts, to get acclimatized to the time zone and to allow a buffer for flight delays. The conference is in Las Vegas, which has become really expensive. I’m not all that interested in spending money on overpriced entertainment, or gambling when I could...
I’m about to take my 560SEC on a road trip. I’ve been making sure I had appropriate spares for this road trip, especially things that would he hard to get by the side of the road. One thing on my list was some spare ZH-M. ZH-M is the hydraulic fluid used in the self-levelling rear suspension. Since I was ordering ZH-M I...
I’m currently in Las Vegas, USA for a work event. The event starts tomorrow so I had some time to get acclimatized to the time zone, and a buffer in case of any flight delays. While most things in America have become very expensive in the last couple of years, self service junkyards are still very affordable. This is far preferable to the overpriced...
The sunroof on my 280SE has not worked properly since I bought the car. It would sometimes move a bit, if I played with the switch, but not often. Since I didn’t want the roof stuck open, I didn’t use it. Based on that, I figured my issue was the W116 sunroof switch. The car is booked in for the Shannons auction in...
Ever since I owned my 560SEC, it has always ridden too low in the rear. I have attempted to adjust it a couple of times, but was never able to get the correct height. Using the factory procedure to set the neutral height did not work. At this point a lot of workshops would suggest to rip out the system. This is a really...
I’m currently in the USA for work. I arrived the day before the event I am attending, so had a couple of hours to spare before work started. I’m in Las Vegas, so most people would have hit the casinos or shopped at the outlet malls. Instead, I headed to a self service junkyard to grab Mercedes Parts. I’ve been to Las Vegas...
On a recent drive with a few friends I noticed my 560SEC was sitting a bit low at the rear. I had it parked next to a 380SEC, which I am pretty confident is at the correct height, and my car was lower. Based on that, I started reading through the section on W126 self-leveling suspension adjustment to work out why. The length of...
The previous owner of my 560SEL had the self-leveling rear suspension removed. He told me that he was having problems with it, and the suspension shop he took that car to (Pedders) advised him to remove it. This was pretty bad advice, but he wasn’t to know that. A 560SEL should have a supple ride, but my car rode like an old pickup...
My 560SEC has been leaking from the power steering and self leveling suspension. In both cases, it is obvious that (at least some) of the leakage is coming from the low pressure hydraulic hoses. It is possible there are additional leaks in the steering, but fixing this obvious one is a good place to start. I had looked at doing this job...
Before I begin regular usage of the 560SEL there is further maintenance required. Per a receipt I have, a new timing chain and tensioner was fitted around 20,000km ago. This is obviously a good thing, but it was a shame that while this was done, the M117 timing chain guides were not replaced. The guides (and ideally the sprockets) should always be replaced at...
After driving the 560SEL more I have decided to reinstate the W126 self-leveling suspension. I am probably one of a very small group of people who is putting this system back after it is removed. A 560SEL should drive really nicely, but the current springs and shocks make the ride like an unladen ute over rough surfaces. As a contrast my 560SEC has an...
After owning the 560SEL for a couple of weeks I’ve had a chance to spent a bit more time looking over the car. I’ve also had a few more opportunities to drive the car – covering about 150 km over the time. This is a lot less than I would normally want to do, but with COVID19 lockdowns, I can only drive the car...
A common feature of Mercedes cars from the mid 70s through the mid 2000s is the self-leveling rear suspension. This system is standard on the wagons, but was commonly specified on the higher end sedans too. Mercedes-Benz Australia was particularly keen on the system fitting it to coupes and even mid size saloons. The system ensures that even with a heavy load in the...
