Thought I’d post this up and see if I can clarify the subject as it seems fractured in numerous other posts.
I’ve come from a D3 and D4 background and having retro fitted the remote park heater function on all my other LRs thought I’d give my L405 VSE the same treatment.
Having bought another VIN licence from GAP for my IID tool I went into the CCF and switched on Timed Climate with immediate success. I then went into the remote park heater settings and enabled that also, naively I tried to pair the remote blipper to the car by removing the 5amp fuse in the fuse panel behind the glove box but it was no dice. Trawling through the forum I found where the receiver for the remote blipper should be, behind the rear offside panel in the boot, pulled the panel back and there wasn’t a receiver there. A bit of digging about in the dark I found the multi pin plug and aerial fakra connector, so the wiring was already in place. Found the part number I needed, CPLA 18D540 AA, and ordered one from eblag. Fitted the receiver and paired the remote straight away, pushed the on button on the blipper and on came the flashing orange light on the dash that indicated the FBH had fired up. At this point I felt pretty pleased with myself, went inside and made a brew, came back outside and pressed the off button and sure enough the heater went through the shutting down cycle. Tried to fire it up again but the remote blipper’s green light just flashed rapidly for 5 seconds, went off and nothing happened under the bonnet. A good bout of head scratching and another cup of tea later the IID tool came out and faults were read, I can’t remember the exact fault code number but it was along the lines of heater diverted valve fault. Took the car for a quick spin and brought it back, locked it up and let it go to sleep. Waited 20 minutes and tried the blipper again with success this time. What I’ve found out is the heater or car doesn’t like to be fired twice without being driven in between actuations, don’t know why, this might be a normal thing even on cars with factory fit remote FBH operation.
