I have bought a new Coachman Olympia and picked it up on Thursday. Whilst towing every couple of miles I kept hearing a beep, it sounds like when the indicator is on but there is only one beep I never had it when towing our Lunar Clubman SB. What would cause this beep?
Now you have discovered the bleep only happens with the caravan hitched up, it could be something to do with the habitation relay. It could be telling you that the fridge and charging are working but all the other 12v electrics are off. Dunno! Just a thought.
A call to the dealer may produce an answer. If you get to the bottom of it, it would be interesting to know the cause.
I rang the dealer and will have to take it in. He said that they would tow it with their vehicle and see if it happened then, they would then come with me in my vehicle to see what happened. I told them that as I am going away it will have to be after the 28th. I am going over on the 18th for a preview of the 2016 vans (only to get a free ticket to the Birmingham show) so will mention it again then.
