Strange cruise control issue

[Mechcanico Lee]

Yes I'm with Del never heard of that one but some thoughts
If you press esp button to disable traction does it still do it
Are all the tyres of similar wear ...... thinking slight miss match on rolling circumferences on wheels .

Had a 5 series bmw few years back that would not always go into top gear and engage converter lock up and also would drop speed on cruise control and then pick back up ...... it happened when owner replaced rear tyres only

The fix was replacing front tyres aswell !
