No radio signal! Help

jayartibee · 02-18-2021, 12:19 PM

bog standard 'Professional' radio - no extras, no changer etc. - suddenly lost all radio signal - no stations on FM or AM, nothing on Scan.

Any ideas, folks? Is there an aerial amp I need to check?

sorry - E91 325

It would not be and e91 if it is a 525 though the Radio electronics would
be the same.

blimey what a moron. 325i sorry

Anyway can anyone point me in the direction of what to try?

in e91 antenna amplifier is in rear door spoiler
there is well known problem - wiring break from body to rear door, right rubber grommet
and second problem is antenna amplifier itself, after long time the rubber isolation dry out and water can reach amplifier and damage it

I can make it work with the tailgate in certain positions so your diagnosis is spot on.

so it's a RHD vehicle, there are two rubbers on the right, one on the left - any idea which on the right? And is it a voltage feed or is it a coax for the signal?

Read the above.

jayartibee · 04-11-2021, 05:31 PM

that's for an E90, not 91

Anyone tell me which rubber the offending cable goes through please?

Indeed plenty of Googling gone on. Complicated by window pop not working either (separate issue).
The cable that breaks - is it signal or power?
