Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Have you checked if you also have one (or two) in front? Might be part of a built-in/integrated system so no RD unit per se .

The control for a built in RD can be down by your right foot (LHD car). Are you sure you do not have one in the car before you start ripping things out?

POST 7Original post
I found one on a Jaguar XJR that I bought. The PO only had it a short time, and he had no clue. Worked great!
