Update:
Ian spoke to the garage and they have informed us that land rover are aware of the problem and are working on a fix. The fix is not due to arrive until July....
The fix apparently is a software upgrade.....which is what we suggested at the begining that it was a leak or possibly the ECU.
So fingers crossed we might be getting somewhere. I'm not upset I can't take the car in until July I'm very happy that we no longer have to take the car in for a pointless journey knowing that they are stabbing around in the dark.....
Here's hoping we solve this problem once and for all.....
