Mobile technicians

evening guys I’m looking for a mobile tenchnician near Chesterfield area, so basiclly I purchased a disco from auction ( schoolboy error) after getting it home and pottering about I noticed a judder shuddering at around 30mph, looks like torque converter according to a few lads on here! Had it straight to my local friend at his garage. He plugged it me in and said EGR valve needed swapping! Did that to start with then he swapped me a unit on the bottom of gearbox he claimed this would cure the juddering and stop Car going into limp mode. It hasn’t done anything I then tried dr tranny to no avail! Then plugged it me in again as it was always going in limp mode said it was reading loss of communication so swapped battery to no avail. So basiclly I’ve spent £800 and Car still juders And still goes in limp mode every 70 odd mile! It clears once you turn engine off and on again! So I think I need someone who’s has the Land Rover computers etc. The codes need reading properly. I can’t keep changing parts to see no difference. Any help me appreciated it’s on 08 plate discovery 3 with 121k on clock

Jamie I meant the D3.co.uk forum, not on here, most D3 and 4 havent moved down to the enthusiasts yet, so the knowledge base isnt there.
