Innovv C3's and lately Aukey DR02-D
Bought and installed a DR02 set into daughters VW Jetta, no problems, liked the setup, when the Innov C2's started to die bought and installed DR02 into a BMW 5 Series (2011, F10), in the Jetta could leave the DR02 plugged in all of the time, no problem with central locking, in the BMW if I leave the DR02 live, then it appears to block the remote keyfob signal, I have to unplug the power feed from the front cigarette lighter, watch the DR02 power down, then the remote locking works again.
Any ideas? Clues? It'd be good to not have to unplug the DR02 all the time as occasionally forget to plug back in.
 
Much later, have installed ferrite cores on power supply, these have helped leave ciggy lighter power plugged in, not quite 100% yet but can use the remote to lock/unlock, when it stops raining may add some to the rear cabling as that approaches the shark fin area (remote receiver) - see if makes any difference.
You can get packs of 20 or 25 various sized ferrite cores quite cheaply.
