NCT fail on rear suspension imbalance

honda boi

Hi all,

2014 Bmw 520d f11 failed NCT this morning on an imbalance on the rear axle.

Most cars I've had I've just changed the rear shocks and that usually does the trick.

But I see this car has air suspension in the back.

My question is could the imbalance be something from the airbags in the rear? Or do these not affect the imbalance readings?

Priced a set of Sachs rear shock absorbers at about 300€ so don't want to waste it if it could be an issue on the airbag side of things.

Car drives great , no noticable issues. No sagging In the rear.

Edit can mod move this to the motors forum.

😀 Bargain of the year so far for me.

I had a similar problem on my Audi Allroad a few years back with the rear suspension. It also had air suspension. I replaced both rear shocks and it solved the problem. I'd doubt it would have anything to do with the air springs themselves. In my experience, air springs can only have one problem, they leak - either slowly or worst case you get a blow out. I couldn't see them cause an imbalance.
