Reply With QuoteYou're not the first person to get the fault when 1 tyre is soft. The differing wheel speeds, steering angle and suspension heights all have a part in the algorithms.

I learnt something new about D4 suspension during our club trip to Eucla/Nullarbor Caves.
At the end of day 2 on site the fuel pumps broke down at Eucla and I was forced to go on about 10 km to the border servo where I aired up (we had been on gravel roads for almost all of the day).
After leaving to head back to Eucla I got a warning beep from the GAP Tool and a fault code "C?A 07-62 Cross Articulation", and advice "suspension fault max 50 kmph".
After 2 clears, following which each time the fault returned, I followed instructions and tootled back under 50.
At Eucla it transpired after a while that I had a slow leak in the front drivers side tyre. Changed the tyre and hey presto - no more faulting. On returning to Fremantle found out that the tyre had sand in the beading and a slow valve leak.
I never knew that the suspension system was so sensitive.

SupporterYeah, it's happened to me as well.

One of the earliest incidents that I rcall was a persistant fault on a new RRS. Evetually it was spotted that it had been fitted with 1 D3 wheel or tyre at the factory, being a 55% profile instead of 50% profile tyre.

SubscriberMIL has a BMW with a tyre pressure alert that periodically activates but no TPMS and I’m sure it just picks up a signal from the ABS and produces a warning. Very low profile tyres so must be incredibly sensitive to any diameter disparity.

My L405 tells me on every start-up that the spare is low pressure even though there's no sensor on the spare nor a receiver for the spare, but that's a different oddity.
