I've had the 'Travel Assist currently unavailable' issue start on mine recently. Seemed to get noticeably worse during the cold snap but has continued to deteriorate since the weather has warmed up. Generally it was at least settling down a minute or two after starts but has got really bad recently (was going off every couple of seconds the other day whilst behind a lorry). When I return home I generally do a 3 point turn just up the road before driving back to park and it always seems to start pinging away during that manoeuvre too.
Car booked in for Thursday next week, I just hope they don't muck around too much resolving it. The relationship with my dealership isn't exactly on the best of terms anyway (delivery of the current car was an epic catalogue of ****-ups and I still have an ombudsman complaint against them pending from when I bought it).
Has just the software updates fixed this for many people or has having to swap out the steering wheel been a common thing?
