Hello Robin @woodsmoke

First off thanks for the reply. I thought the fuel management unit was the box in the boot bolted on the drivers side rear wheel arch? This unit I’ve had off & cleaned & will be checking any results on Tuesday (out till then). I thought the box under the carpet beneath the passenger side seat was the amp for radio/tape? Have I been looking at the wrong unit then & does the seat have to come out to check it or can it be removed leaving the seat in situ?

Thanks again, Dave.
