Luckily that's the only old style one on there so replaced and now all is well

And today a new issue! My reverse lights are on all the time!
Will go have a play at dinner time, i presume the plunger on the switch is sticking so ill take it out and clean it when i find where it is!
Still drives brilliantly and has towed the caravan happily a few times now, including up Garriby Hill which some cars struggle up without a caravan on! Didnt have to change down to maintain speed!
Its a brilliant engine, so flexible.
