Hi

While driving home today my 340 completely lost all sound, parking sensor sounds no longer work and volume knob does nothing. I get the error pop up on the idrive with "Note-No warning tones", no other issues with the idrive system and nothing else giving errors.

Got to destination tried a soft reboot of the idrive system, no joy with restoring sound

Did a quick google and most posts point to AMP failure frown .

No prior issues with the sound system annoyingly.

Has anyone had similar with their HK system before, was it repairable (or as I'm suspecting needs replacing) and/or is there a plug and play replacement people have tried for the AMP (although it seems will need coding) before this costs me many hundreds of pounds to rectify frown

Car is;

2016 340i, 81,000 miles, HK system

Any knowledge/tips greatly appreciated!

Rob

Check the 40A fuse in the boot; can't remember which it is, but there's not that many, so check them...

If still no luck speak to Baris at Carphonics: https://carphonics.co.uk/product-category/shop-by-...
