Is there not an Independant down your way. There diagnostic charges should be much lower than the main stealer. If I do a straightforward fault read and reset, I charge €40 per hour (Approx. £30)-minimum charge 1hour provided they bring the car to me, if I have to go to them, obviously it's plus travelling time and petrol expenses. You can get the faultmate set up from Blackbox at a moderate price but it is vehicle specific and will only work on one vehicle I.D., however it will cover all the systems. My Rovacomlite and software modules has cost me over £2000 to date, although I have the P38 well covered, I could spend a fortune on modules for other models in the LR range. Used units are like rocking horse s**t to get hold of and only come up very rarely.
