Please please please can someone help, we have a 05 Discovery TDV6 HSE Auto it is fab, however i have just bought a twin wheel caravan which i was told the disco would have no trouble at all towing in fact the land rover dealers said the car would no even know it was attached ***WRONG** the car does know it attached, because when we drive for approx 10miles it decides to throw a proper wobbler. The first fault shows 'hill decent not functioning' this comes on when we go up hill !!, then the park brake lights up amber, then the cruise control will not stay on and it keeps jumping out of gear, the rev counter looks like a wind screen wiper because it is going up and down like mad. We have had it back to the dealership and they have re-loaded the software and changed a bit of cable but it still does the same thing, this is not only embaressing but dangerous as well because we dont know when it's going to happen and it could and has happended when we have overtaken, the car goes out of gear into netural and we just cannot get past the car we were trying to overtake. We have checked that the caravan is not too heavy and the tow bar was bought from land rover and fitted by an expert, so we just cannot understand why this happens, I am sure it is not something that every disco owner has to put up with or is it??? any advise will be great. The fault disapears when the caravan is unhitched.
Thanks for listening
