 Other than a recurring ABS fault (same sensor replaced twice now and the fault has just reappeared) the C6 had been behaving.

But, when stopping the engine, there is something of a clunk when it stops. Not every time, but most times.

It starts and drives smoothly.

Any ideas? I read that there was a complicated rear engine mount that could be a potential culprit, but that it is hard to get to. I couldn't find it in the documents area.

Any advice welcome.

No advice on the clunk but I also replaced the front sensor twice and the fault reappeared.
I replaced both rear sensors and have been OK for 3years since

I don't think this is suspension component-related, since the car is static and gearbox in park when I turn the engine off.

Is your wheel alignment causing tyre wear issues? Mine wore heavily on the inside, hopefully now fixed.

 no mine is different, i get severe wear on the outer part of the tyre but only on the one on the front passenger side.
