P38A Leaning when parked

Hi Guys,

Got a slight problem with my 2001 P38 Westminster's EAS. All is well whilst driving other than a slight lean to the left (potentially a bad ride height sensor or bad calibration?).

It's when I park up and leave the vehicle that the problem truly presents itself. If parked on land with the nose down or with the left side of the vehicle downhill the car will immediately try to self level and fail totally. You can hear him clicking away as soon as I close the door and the front left corner starts to dip lower and lower.

I don't believe that this is caused by a leaky valve block as if the car is parked with his nose pointing uphill he'll happily sit for a week with all corners at the correct height. All the bags are relatively new too.

My temptation is to hook the car up to the computer and see what the ride height sensors are saying (have got the lynx diagnostic unlocked for P38). The worry is that I'll end up doing something stupid which requires the ride height sensors to be recalibrated and I unfortunately don't have the special blocks required for this.

Based in Glasgow and currently on leave from my job offshore until march so if anyone local has more experience with EAS troubleshooting than I do then I can swing round with beer

Cheers,
Alex.

connect up the diagnostics make note of the settings it is and compare with the required settings.. don't worry there's not much to screw up and you certainly wont need to have the sensors recalibrated

This does not help but one of mine did it when the mood took her
Sensor?? sorry cant tell you anything clever ((

Definitely do the EAS diagnostics, especially as you have Lynx already. You can read everything without changing settings, and post your results. If the left front is already lower, and then dips when self levelling, I would suspect the height settings are wrong and you have leaks. Check all the usual stuff in the EAS Technical Archive posts at the top of this forum section.

Try some parking tests with the EAS manually set to Motorway and Extended heights. This tends to highlight air-bag leaks in the folds.
Also try removing the timer relay overnight to see if the system leaks with self-levelling disabled.

Thanks very much chaps. Will get Wes hooked up to Lynx today and will report back with the outcome (and potentially some screenshots etc).

I had begun to rule out leaking bags as he'll sit very happily at normal or extended ride profile for well over a week providing there wasn't a lean to the left. That said. I'll definitely have a play around and check the bags again while I'm looking at the system.

Shall report back, cheers again!

Alex.

I think you might be able to replace the delay timer with a standard relay and it won't self-level. That should allow leak checking without having to pop it in and out all the time.

Hi all!

Sorry for the slow update to this thread.

Would you believe me if I said it was an oil cooler pipe that had caused the lean on Wes? One of the pipes between the oil filter housing and oil cooler had started leaking, the oil slowly started to creep down the chassis leg and eventually found its way down into the ride height sensor. When I looked at the sensor it was soaked in oil.

So after a new sensor, ride height calibration with Lynx (and a new oil cooler hose of course), Wes is finally sitting square again.

Can't help but be amused by how such different problems can be linked (or in this case caused by one another).

Cheers for all the help and advice,
Sandy.

Mine does this, it's the delay timer (it checks the ride height and adjusts every 6hrs). With the battery off it doesn't an inch.
