Well I’ve just had a software gremlin! Just came back from a spin around the country lanes and pulled across a fairly narrow road to back into my driveway, stuck the front end of the Grenadier into the long vegetation on the bank , parking sensors going berserk! much as I tried it would not go into reverse or drive. The guy behind me in a truck patiently waiting as I happened to know him. Switched engine off 3 times and still couldn’t engage reverse or drive and completely blocking the road. Fourth time lucky start engine turn parking sensors off and into reverse it went and back up into the driveway.
