Hi everyone,


First time posting, so I apologise if I've missed anything I need to do. Wondering if anyone has heard of or seen this issue before? I've searched many forums, but it doesn't seem this has been covered specifically.


I have a 2003 Range Rover Vogue L322, and recently the radio stopped working. When the car was turned on, 9 beeps sounded that I hadn't heard before. Low and behold, water had got into the left area in the boot where the amp is. I disconnected everything, cleaned and dried it all, still didn't work. Took everything to bits, cleaned all the parts with flux cleaner/remover, put it all back together, still the same beeping and no radio. It seemed like the radio and computer etc were still working, so narrowed the issues down to the amp.


I found a replacement amp on eBay for quite cheap so thought I'd try it out: https://www.ebay.co.uk/itm/bmw-e38-dsp-amp/123826341405?ssPageName=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649.


Didn't work, but the beeps stopped. I noticed when unplugging the 18 pin connector on the amp with the radio still on, there was music for a second!


After swapping around some wires in the 18 pin connector, I managed to get it to work. Sound in all the speakers, bass etc, all back to normal. Still works when turning the radio on and off.


Now, the issue. If you turn the car off and back on, no sound comes from the speakers again (although you can hear speaker 'static' if you turn them up full volume). If you unplug the 18 pin connector and put it back in, it works again.


Obviously I don't want to to that every time I turn the car on, any ideas for a potential fix?


Thanks,
James

Not had any luck here. Bought this cable off eBay to see if I could recode the DSP using the details below, but couldn't get it to connect to Navcoder or NCS Expert. Not sure if anyone has ever had any luck connecting to an L322 with either of those? Followed loads of different instructions and just wouldn't connect, even though it would be recognised fine by the BMW INPA application.

https://www.ebay.co.uk/itm/USB-OBD-K-Dcan-...2749.l2649

Insert the following parameters
Polling Timeout: inaktiv
Controller: mid_basis

1. Read the AMP module with NCSExpert in Manipulation mode
2. Edit the module settings and find the value : BEDIENELEMENTE
3. Change the value from "bordmonitor" to "mid_basis"
4. Save the new configuration file
5. Run SG_CODIEREN in NCS Expert
Think i'll try buy a replacement amp from the same car instead of a BMW one, surely that will work :confused:

You can't communicate with the bmw amp via the L322 because the bmw amp has a different software that cannot communicate through the L322. The process is very complex so your best bet is to use an oem direct replacement.

Could I hell get this to work, ended up biting the bullet and shelling out for a replacement amp pulled from a Land Rover instead for about £160. Works a treat.

Good news.
Does it mean that the amplifier from BMW has a different coding than the same for Land Rover ?
Or is it that the first (and cheap) amplifier you bought was not working ?
