Hi, I have a Rang Rover 2007 Vogue with the midrange speakers on both rear doors not working. It's odd that they both don't. One I can imagine a loose thread but both. With the GAP tool the error code becomes: B1A02-13 (2F) Speaker 2 circuit - General electrical failure - circuit open :B1A01-13 (2F) Speaker 1 circuit - General electrical failure - circuit open. anyone have an idea how i can fix it?

All vehicles show that error - a legacy of the BMW era.

Best thing to do is to multi meter test the plug. You should see current each time it pulses. If so, replace the units. They're not expensive - £45ish each in the UK.

It's not to be unexpected that after 15 years they have blown. 2015 Range Rover Autobiography 4.4 SDV8
