I purchased a used 2000 LR Discovery from a guy in CA, up front he told me I needed a new CPU unit which would eliminate the idiot lights on the dash for emissions, cost of the used unit $450 and with labor I was thinking a $1000.
I brought it in to Rover N Techs and automatically they told me the CPU rarely goes out and it should be something else. They were jammed with at least 20 cars in the lot and told me it would be 10 days. I left my car and got a call noting it wasn't the CPU unit, someone replaced 2 sensors backwards and caused the error.
Charge $145, which included the scope, fix the sensors and labor.
As a business owner myself for over 30 years, the experience and honesty these guys shown was what we call old school.
I will pass this story on forever and my Land Rovers will go to these guys, great job!
