"Dynamic Damping Control failure"

[Busterboo]

15 seconds after the car goes into Sport+, the warning 'Dynamic Damping Control failure' appears. The adaptive suspension then stays in Sport+ until the engine is switched off. (On re-starting the engine, the suspension has returned to 'Normal' and the display shows 'No faults'.)

Help, please.

I wouldn’t like to say wether that’s the dampers at fault or the module that controls them, needs scanning

Thank you, Rob. BMW thought the same and replaced the 'Electronic Damping Unit' (@ £600+ on insured warranty), but to no effect.

Maybe the sport rocker switch itself..? :?

Now there's a thought, John. Thank you.

Did your 35iS ever show a Dynamic Damping Control warning?

Does the E89 have as stability module that provides input to the damper control? Just a thought.
Another good reason to ditch the adaptive dampers for performance kit maybe......

In answer to your question, I don't know. BMW replaced the Electronic Damping Control unit, but this wasn't the solution. They then, as my indy predicted, replaced the rear dampers, which was. This means that the car has now had new dampers front and rear, the front having been replaced in 2019.

Oddities that emerged were (1) BMW were very quick to want to replace the front dampers, even though they had only "a very slight leak" and (2) the fronts are significantly more expensive than the rears.

As for your suggestion about swapping the adaptive damping system for a performance kit, again I don't know, in this case because I haven't driven a 35iS with one. The BMW system works very well, not least because it changes the steering, too. And, as long as you have BMW Insured Warranty and don't mind losing the car for a day or two now and then, is worth having. (The Insured Warranty covers other E89 weaknesses, too, of course.)

I like the car a lot and, thanks to the help of members on the Forum, a good indy, the Insured Warranty and my local AD (who's improved a lot recently), I hope to keep it. It's done 72.5k miles, 52k under my right foot, and I'd like to run it until at least 100K. Fingers crossed. :driving:

Maybe the tyre pressures are putting too much shock load through the dampers.
You could try lowering them a bit?

oke:

(PS. I like to be predictable :wink: )

In all seriousness, though, I'm lucky to live near a network of good county roads, on which BMW's recommended tyre pressures work very well.

That said, it's not all down to pressures (36 front, 44 rear), is it? Even now, I remember with horror the runflat Bridgestones the car came on.
