Update: Been in touch with Gap and they have given advice which I've followed but still no joy.
In service/test mode I can access the bcm and see that Transportation mode can be activated and deactivated. Select Deactivate and confirm, Gap tool says standard mode now active, so one would assume that all will be OK, but no, reads faults again and Transportation Mode still active
Back to Gap, and they suggest trying to deactivate it by using the suspension setting on the bcm. Same process, gap tool confirms mode is now standard, but again fault code says Transportation Mode is still active.
I've not yet got back to Gap to see if they can suggest anything else, but will do. In the meantime I have booked car into Worldwide LR here in Southport for later this month in case I've not been able to resolve. Just a bit frustrating to say the least. But hey ho, could be worse.
I'd love to know if anyone else had such issues and how it was resolved?
Dad at least is home now, but requires 24 hr care, so plenty to keep us occupied
To be continued...
