P38 4ltr 2002 thor 35mph EAS

Be careful if you have to bend the arms, that's how I broke mine!

I have known damaged arms and sensors on here but my gut feeling is that yours are probably fine. I'd certainly be removing the delay timer before shelling out on sensors. And maybe checking driver pack connectors if it is still playing up.

That's really kind and helpful posting that. Often a "look in rave" is posted. I've got RAVE and do look in it. Trouble is, until you get the ground level understanding that you chaps share, the level is just simply beyond a layman. I 've got the manual on cd and RAVE on my hard drive. Searching, reading absorbing and learning is another thing entirely. It's like someone asking me how to carry out a function editing a documentary or preparing a sound track. "look in the comic" just serves to bewilder. Who doesn't like instant gardening? Isn't that what forums are for to an extent?

BTW, where the hell is "west wing" ??

I've had that at back of mind all along, to tell the truth. I got the 35mph in Valencia. Did the last 500 miles slowly dropping to the bumps. The fuse box burnt up, literally. What it didn't take with it isn't worthy of mention. I'll check the contacts out tomorrow.

myfirstL322 has sussed it. I'm not sure myself. I'll ask matron.

Listen up, men. At the risk of being laughed out of town. I think you've cracked it. Obviously I had to address leak city which I have. The 2 max readout across axle did it.Hitherto the levels were being arrived at and the pump cut out. Then the clattering and then the pump again. Then, I realise from what you've said it will level down if the magic 2 difference is exceded. I decided to reload the calibration with a say so figure resembling my actual obtained heights only with the offside 2 points below on all stages of lift. Voila. The pump cut out and stopped chattering and the motor stayed still. I thought if I could arrive at this point at least we could fathom the next step. Damn me. I measured the hub/wing on all four corners and it was on an even keel. I also before starting blitzed the connections around the pump and to the controller. Matron says she wants you all to come to tea. There'll be buns and pop and jelly. She says I'll have to have an injection first in case I get over excited.

Yep, that 2 points across the front axle is important. When I fitted my new sensors, I spent ages getting them to read the same when on the blocks and it works fine now.

I might just pass on that offer, the last party I was invited to was blatantly mis-described


But.....if it's really a jelly n ice-cream do I'm up for it

It's all off. I know I making this painful. At standard height the pump runs for between 30 & 60 seconds. Then cuts out for no more than 8 seconds. Then the clattering starts whilst at a standstill. There's still the clattering to an extent while the pump's running. I've saved cross axle readouts to within 2 but when I look at the heights as are they're all over the place. On the blocks all read out as expected. The pippy light things steady in position smartly but the pump still runs as described, even in access but not to such an extent. The clattering is the feature of this whole thing. If someone can wave a magic wand over this I'll buy tons of waxoyl and throw a waxoyl party. Thanks in anticipation . Regards. P.

Can you film it doing it?

Do you not know anyone with a driver pack they can lone you for a test fit, maybe that is failing and confusing the ECU. Normally if that is the case you would get an air pressure constantly high fault on diag. Compressor should cut out around 140 to 150 PSI and not start again until the pressure drops to around 120 PSI. Suspension cannot adjust downwards when compressor is running but can go up if doors are closed. Start engine with a door open and see what compressor does then. It should run up to pressure then blow off. There should be no adjustment up or down with a door open. Have you done the diaphragm leak test?

Wilco. Send me a dose of your patience as well, please. I can't get the fuse box burnout I suffered in Spain out of my mind. It started with the bump stop 35mph waltz. Coincidental to bridging the pump relay flames and glowing manifested from the fuse box. The engine ecu, MAF and lambdas took a hit along with the alternator. The EAS pump and all the above were replaced after the purchase of hawkeye and ancilliary dongles and cables, and ecu synch thing. Prior to this we did 500 miles on the bump stops townig. The replaced airbags showed evidence of their suffering. However we did the 2000 miles back with the suspension seemingly OK. It was with this experience in mind that I've undertaken this "preventative" overhaul.My guess is the pump was performing as mentioned and, being new and not from a mickey mouse source, got us back due to its newness. I'm green on P38 issues, in case nobody's, noticed but I'm OK on electronics and electrical circuitry. I know that solonoids only need a pulse as opposed to a full circuit 13.8v blast. My LPG injector solonoids took a hit such as this. Fortunately, the LPG ecu survived. I honestly can't see any leaks. I've effectively jet washed the chassis with my soapy water squirting and I've got the cleenest valve block in town. My gut feeling is that I've dropped a clanger somewhere in the valve block reassembly. I'm totaly capable of making silly mistakes.Could the driver pack and/or the height ecu have taken a hit or, like me, are going downhill. Please don't think this is a challenge to the expertise around here. I'm testing my logic out, if you don't mind. I'm off to location later. Lights and moby ready for action.

Wammers. I'm very sorry I haven't come across your gospel until pwood999 pointed it out. I've printed it out and I'll spend the day collecting what brain cells I have left. When you've hit the panic button it's barely possible to think straight especially on a new subject. Again, can you send me some of your patience?

Patience has been sent and should arrive first post in the morning. However you did mention Hawkeye which fills me with dread.

I know. I tried to order a nanocom but they couldn't guarantee delivery in a suitable time and hummed and arrrd about sending it to spain. I lost patience with them. I know I've offended but I was stuck big time. I used a known supplier who first of all had all the gismos in stock and shipped it out within a week. That's going some in spain. Once something gets into the hands of correos we're talking weeks from arriving in spanish mainland. Also one in fifty parcels go missing. Only equalled, I gather, by Italy.So far, it's done everything a mere mortal such as me has needed. I already had wilson storey's software but I left my laptop and all at home to save weight ! My tools and all ! You mean I've got to wait till tomorrow for patience ??!! MATRONnnnnn!

I started from cold this morning with a door open. Pump ran for a minute and shut up. Nothing happened for ten minutes while I read the gospel. I shut everything up and the pump fired up. With finger over exhaust not even huurgh. As soon as the pump cut out it nearly blew my finger away. And then back onto the routine. Pump run, exhaust blast pump run. Nothings happening now on switch off as before when I got exhaust and lowering/levelling. I've remeasured and we're on an even keel. So, I've made some progress and no movement overnight, either. Everything seems fine except for the pump running too much. I've just checked the post. No patience as yet.

Would be interesting to stick a gauge in the fill line to tank and see at what pressure the compressor blows off at and what pressure is when it restarts. That would be pressure constantly high to me. And it should show up on diag as pressure signal constantly high. Maybe not on Hawkeye though. Try your EASunlock and see what you get. If that is the case suspect a driver pack diode or some component has failed and feedback is interfering with ECU. Common problem cured by new or replacement driver pack. The driver pack is a slave of the ECU. ECU signals it to perform functions at voltages the ECU can't run. But the ECU does not like it if it shouts and the driver pack shouts back.

No faults on EAS unlock nor Hawkeye save vehicle has moved. I'll run them all again now I'm getting a glimmer of understanding. Many thanks for the prompt reply. Regards. P.

Hawkeye gives me live data. The pump is shutting off as I get zero error betwixt target and actual height. Then straight away I'm getting error readings anything between two and eleven. The car moves trying to level I guess and of course the pump fires up until zero error appears for a few seconds. I can see the target heights are as I input in EAS unlock. With the engine switched off nothings happening at all.just back from lunch decided for the hundredth time to check for leaks. Put to extended height and the pump shut up and didn't kick in again. Tried standard height and the same old story. Pump, stop, exhaust, vehicle move, pump.........Also back to nearside a couple of centimeters down. Pumped up and at rest. I'm becoming deflated.
