M272 Camshaft position sensors

When you own a modern Mercedes-Benz, you seem to be playing constant whack-a-mole with the check engine light. I’ve written before how silly I think the check engine light is, but we’re stuck with it. Personally, I would just drive older cars, but this is not for everyone and my wife has a 2007 E350 Wagon. There were two codes this time.

The first set of codes were complaining about the correlation of the camshaft and the crankshaft on one bank. I had previously changed the magnetic actuators, which temporarily fixed the problem. If the car didn’t sit outside the […]

15″ AMG ‘Penta’ wheels for my 450SLC

I’ve been on the lookout for a different set of wheels for my 450SLC. It is currently running a set of W126 second generation alloy wheels. I like these wheels, but they are not quite right for the 450SLC. My 560SEL uses these same wheels, but they are in need of refinishing.

I thought of a few options for the SLC.

Standard 14″ Steel wheels with colour matched […]

BM2 Battery Monitor

A couple of months ago a friend showed me his BM2 Battery Monitor installed on his 420SEL. It is a bluetooth enabled battery monitor that connects to a phone app. The app lets you monitor the battery in real time, run some tests and download history from the battery monitor device.

I already have various battery testers which are useful for standalone battery testing. However, I didn’t have a good way of checking the overall charging system of the cars. In particular, I have seen some strange behavior with the radios in my 250SE and Citroen DS that may be […]

560SEL front suspension rebuild

This week I got my 560SEL back from having a front suspension rebuild. This wasn’t something I really wanted to take on myself. My SEL drove well, but there was some looseness in the front end. As I plan on keeping the car long term, it made sense to rebuild the front suspension to restore an as-new ride.

The front suspension rebuild included new upper control arms and associated bushings, lower control arm bushings and sway bar bushings. I went with genuine for the upper control arms and Lemforder for the lower control arm bushings. The genuine parts are expensive, […]
