So's mine. First port of call for electrical gremlins.
So's mine. First port of call for electrical gremlins.
Drove my Green P38 up to Edlesborough yesterday. Worked perfectly all the way there. Then in the evening the EAS repeatedly did the random high mode again. Managed to catch it & lower again before it faulted. Put Nanocom on it, but no faults.
Wondering if the driver pack or connectors need sorting again, causing valves not to actuate so it thinks the car is grounded.

My question is and without knowing any better.
Doesn't the ecu read the sensors and then tell the driver pack to adjust accordingly?
If so would looking at the ecu first be more productive my good man.
Mine does this same thing occasionally

Yes it does. During the drive I had Nanocom connected so I could see the sensor readings which were all about right. Also did a recording which I'm gonna check later.
Sensor(s) out of range should show as a fault. But as there's no direct monitoring of the driver pack output, the ECU simply checks the car changes height when it opens valves. Hence if it's lowering & sensors don't change the dumb ECU thinks car is beached & raises it as far as possible.
Might also try adding a new smoothing capacitor across the 12V supply as close to the pack as possible.
Bench test can wait until I'm less busy & weather is warmer, as we have three other cars to use !! If I find something useful will do updates on my other thread.

Electrolytic failure in the driver pack commonly causes that problem, it allows back EMF spikes from the solenoids back down the supply line scrambling the firmware in the ECU.

Yes the sensors are read before adjustments are made, the driver pack is just a signal amplifier to drive the solenoids.My question is and without knowing any better.

Definitely will give it a try, probably across the power wires close to the pack. Still have not managed to fully de-pot one of my spare driver packs & get the PCB out.

No need yo fully de-pot the PCB, the electrolytic can be changed just by removing the potting around it, snip the wires of the old one close to the electrolytic and solder the new one to the wires. I do Have a fully de-potted driver pack that I used for scoping what was going on.
Before the key saga i had a front end knock.. not had chance to get the wheel off the ground yet but gone from low/highway/high a couple of times and now i can rarely hear it.. i think that confirms it's one of the control arms worn out and settled in a different position.. something to check as soon as I've recovered

Spent some time of the car today. Changed the diff oil on both ends (concrete floors are fecking cold fyi), some Heko wind deflectors fitted as I think they look cool.
….aaaand started to try and fix the leaky bits when it rains. Silicone sealant around the pollen filter bits to prevent water ingress, managed the passenger side, got to the drivers and half the bolts holding in the cradle were rotten and could I find my metal drill bits? Could I hell. So a trip to toolstation is needed before I tackle it again.
In less fun related news I found my coolant a bit low.. I topped it up a few months back, so this might explain the damp drivers footwell.

Indeed… I knocked off the front recovery point cover and the rear as well … oof! Was able to keep the rear cover and got it back on, but no clue what happened to the front, had to buy a replacement.. It’s all cleaned up and looking respectable again for those other 99%. HahahaIt'll only choose extanded mode if the vehicle thinks in real difficulty like being high centered. You might want to check the underside plastics if you've experienced extended mode

Had a play with 300 bhp / ton?
I'm in love. Went for a spin in a 4.4 Westminster L322 while waiting for the wifes car to be mot'd 
Is it the same colour as yours?I'm in love. Went for a spin in a 4.4 Westminster L322 while waiting for the wifes car to be mot'd

Changed all my interior bulbs for led. Boot light was changed last year for a powerful UK complete unit so nowt to do there. 4 x festoon in the rear roof lamps, rear footwell lamp and front roof lamp, 6 x 501 in the map lights, front footwell lights and both front door puddle lights.
No it's silver but she still wouldn't noticeIs it the same colour as yours?

I could get it wrapped in Black
