Hi folks I need some help Jackie said don't mess about ask on Landyzone they will put you right .We used the car yesterday and did about 200 miles all OK this morning jumped in turned the key dash light's up turn the key to the start position nothing I got Jackie to turn the key and I can hear and feel a relay operate so I change it for one of the others that looks the same no change .No message's on the dash tried the EKA code no change, plugged the Nanocom in and it reads immobiliser disabled operate the auto shift change lever and I can see on the Nanocom the gearbox switch value change from open to closed and back again ,if I put a live feed to the small switch wire the car will start and run and every thing works .Suggestions please (keep it clean if possible ).

Hi folks 'all sorted now starting and running well.

So what was it?

Its was a 40amp fuse which is marked up for the EAS in the engine compartment ,I replaced it and it started but blew straight away I disconnected the compresser and it started half a dozen times no problem changed the compresser for my spare tried another half dozen times all OK compresser is running fine car starts with a 25 amp fuse as I ran out of 40 amp's .I did notice last week it was taking a while to get to height .
