I bought a 2003 SL500 on auction a few months back, and in general, I'm very pleased. But this is one of the weirdest cars I've owned, and I'm not sure if I just got a funky unit, or if they're all this way. I've been a Jaguar guy for the last 40 years, only owning one MBZ (2000 E320) along the way, so I'm not sure if what I'm seeing is normal or not.
1. I was told by the selling dealer that the hydraulic pump for the suspension was recently replaced. I see that it has a MBZ label on it. The car rides fine, but it seems that, when you park it, the pressure bleeds and raises the right front corner of the car. It's pretty much imperceptible, but almost every time I start the car, remove the parking brake, and start moving, the right-front corner drops down. So weird. Anyone experience this?
2. The car mercifully has Distronic adaptive cruise. But it turns itself off all the time with an 'External Fault' notice. There are no Distronic codes logged in the OBD system. Anyone have any idea why this is happening? It's quite regular.
3. I'm pretty disappointed with the amount of brittle plastic on the car; same is true of my 2007 Jaguar XK, but still. Lots of tiny bits of plastic on the bodywork (e.g. the flaps that cover the holes where the roof supports come up) have broken away; I can't imagine these are replaceable for reasonable cost.
Between the color (Aegean Sea Blue), the Distronic adaptive cruise (when it works), and the head unit retrofit by the prior owner that gave me CarPlay and rear-view camera, I must say that there's a lot to love about the car. But these items (esp. Distronic) are irritants. Any idea what I can do about them?
