Was just about to post the same question as mine showed HDC inactive last night after car siting for a few days.....it also managed to go completely flat over the space of a couple fo hours the week before whilst having privacy glass fitted........

Looks liek a new battery for me also....and drive it more (shame that!)

I have been getting the HDC inactive message on start up for about 3 months now but its only really effected me once when i was listening to the radio whilst polishing car and the battery went flat so i just jump started it and its been fine since but still the HDC inactive has been coming on. So..... With the cold coming this past week i noticed the car struggling for half a second to turn over before starting so obviosly its now time to swap the battery so i booked it into my local Land Rover specialist yesterday and they fitted a Genuine Battery for £138 inc vat. (they said the old one was knakered). Big differnece on start up and the HDC inactive message has not returned.

I manged to use the HDC today when driving on the back roads which are very hilly in Queensbury (Bradford - W.Yorks) and the Rangie just coped perfectly with the snowy conditions. The police had shut some of the roads due to the snow, there were several cars crashed into side of road / wall and cars were struggling up the hills even though there was only an inch of snow if that ! This is my first FFRR and i bought it this summer so i was very impressed when it just flew up the steep snowy hills past the other cars.

Cant wait for more snow!! Playtime ! 2003 Range Rover HSE 3.0 TD6
