The problems with dealer service technicians are never-ending. First, they hire junior techs straight out of technical colleges and pay them peanuts. They are responsible for your simple jobs, like scheduled maintenance and basic brake/muffler replacements. Senior techs do the more complex jobs and diagnostics but there are two problems there:
  • warranty jobs are capped at a much lower hourly rate and also reduced diagnostic/repair times;
  • post-warranty jobs are billed at a much higher hourly rate and as a result, customers rarely authorize more than an hour or two of diagnostic time;
Combine this with overall low expertise and high turnover rate at the dealership, you have parts changers that are more inclined to throw parts on the car in hopes that it fixes the problem. On a flip side, how many of you would pay 4+ hours of diagnostic to someone like DiagnoseDan (look him up on Youtube) to hook up oscillograph and graph every output from most sensors to diagnose a failing injector?
At this point in time, when the youngest Mark III is now 8 years old and the oldest is almost 20 years old, it would behoove any dedicated owner to become a diagnostic expert. Paying professional technician rates on these Range Rovers at this point is painful.

Another three weeks at the dealership and they believe they have it figured out. The MAP sensor was replaced, but the intermittent issues with "restricted performance" continued. They'd drive it for a day or two with no issues, then they'd drive it down the road and it would die. After all sorts of diagnostics, they traced the issue back to one of the connectors that fees the throttle body. They said it was connecting but not tight enough, so they replaced it. It's driven for a week with no issues. At this point, I'm going to sell it to the dealership.
