If the dash is not asking for the EKA code then I doubt it's that. As Brian said, needs a security re-learn, read the code in the EDC and write it to the BECM.
There are people out there than can do replacement keys & fobs. My son had a guy based in Bedford that programmed a FoB & spare keys for his 2004 FL1 TD4.
If it's a "temporary import for repair", then you should normally get the duties back when it leaves the UK again. Same with VAT.
Had the same thing a few years back shipping Motorola demo kit to various non-EU countries. It a case of getting...
Hard to correlate. With the engine is running the EAS should see the charging voltage, unless there's some voltage drop between the fusebox & the EAS. Keith's capacitor mod should remove any spikes & glitches on the 12V supply.
On mine...
+1 the dash always beeps & displays the message when connecting EAS diagnostics. Same applies to Nanocom & EASunlock software.
Always use either the "Stop" button in EASunlock, or exit the menus on Nanocom before disconnecting the cable.
Could also be intermittent connection in the pins & sockets inside the connector between driver pack & solenoids. The fix is to de-pin them one at a time & gently squeeze the sockets so they grip the pins properly.
But do the capacitor mod...
Surely if you put schrader valves on the airlines to the airsprings, then there was no point where there could be a "leak in a part of the system common to all springs". Or did you use t-pieces & retain the valve block connections ?
The locking works because triggering the button microswitch (i.e. CDL switch) makes the BECM thinks you're inside the car & want all the doors to lock. Conversely when unlocking using the button, the mod makes the BECM think you want to unlock...
Depends what gaskets you use. Good quality have sealant around the coolant passages. Cheap usually don't.
Cant remember if I used any on the head gaskets, but definitely did around the coolant passages on both top & bottom of the valley gasket.
From the pictures it looks like surface rust. Clean it up & see if you can see light through it ? Then seal any gaps & paint with Hammerite - Kurust. Underneath lots of underseal might work.
But before all that you need to figure out...
If you're gonna weld new metal in, then the carpets & underlay need to come out. If you can clean up the rust & seal any gaps, then it's possible to dry it out in situ.
I had a heater matrix fail back in Nov 2023 (on the way to MOT). After...
Wipe out any fluids first, and then vacuum all the loose debris, especially around the piston rings.
Check all the core plugs for rust & signs of leaks.
Just take the centre dash panel out & sort it properly. Takes about 10mins to get side panels off, lower panel under steering wheel, & release the 4 screws for HEVAC panel, plus slide the radio out. Then you can unscrew the centre dash &...
Sunroof drains - one at each corner. The pipes go down the A & C pillars, and exit into the outside wheelarches. Could also be doorseals, roof gutters leaking, etc.
Unfortunately, it can be coincidence, just had 2 unrelated problems on one of my P38's
Either the accumulator is knackered or the pressure switch is opening before the correct pressure has been reached. My money is on the accumulator.
