Interesting you should say that as it has intermittant HDC INACTIVE faults which I assume is some sort of ABS fault - I'll have a look at that as well.Quote:

Yes I stumbled upon this by accident trying to fix a dead HDC system.
Having cleared codes and got activity, the defect returned soon after the first drive cycle etc.
For grins and giggles (are there any fixing modern cars???) I went scooting about with my Autologic into the many modules on that car. Having found a host of error messages especially in the ABS system I cleared them all out and made sure the ABS system was working as it should.
Then going back to the original fault with the HDC I cleared it again and bingo it all came to life and stayed that way.
Car hasn't come back for the same problem so life is good in the shop (If that is at all possible with all these Yankee blokes I have turning wrenches?):o

Just a quick update to all this. The new wheel height sensor fixed the problem, but after all that, I found a small leak from the LHF airbag when it was at access height - from a fatigue crease in the rubber - no dramas at standard height, so I bit the bullet and ordered a set from the UK. They should be here in the next couple of days. They have 172KKM on them, so they are well and truly due for renewal.
Best price I found locally was $1,130.00 each, but I got the pair delivered for under $900.00 from England. (214 quid each + 142 quid delivery)

Doesn't your tool come with a help section to explain what the error codes are?Quote:

The EAS ECU has no connection with the ABS ECU on the early L322 model that I've heard of.
Keep up Dan, it's not that hard...:)Quote:

The comment about the ABS was in relation to the USA post - I think that he has your truck mixed up with later L322 models which have different ECU arrangements after Ford got involved.
I assume that your price for the front EAS bags was for bags only??
Who do you buy your gear off in UK?
I recently replaced my front struts (bags, shocks and all) with imported UK gear. The shocks only last about 150k so it was well and truly time to do that. I now have the old struts (inc bags) for spares.
In all my years and 100's k kms experience in RRC, P38A and now L322 I have never had an EAS bag leak.
Rolling Bellows (the type of air bags we have on our LRs) will all leak sooner or later, the rubber perishes and they leak where the roll spends most of its time. I spent 8 years working with air systems on heavy vehicles, although I was involved with the electronics side, I spent a truck load of time on the shop floor in both Scania and Volvo. All rolling bellows eventually leak, on heavies the belt or shaft driven compressor can cope with several leaking bags for indefinitely, with our little electric compressors our car can’t.
Most long haul trucks / Busses used to carry spare bellows (just the rubber section), and the drivers were pretty good at changing them roadside, I did one in the shop and it’s not that hard. These days most companies have maintenance agreements so spares like this aren’t carried anymore – call the man…
Rubber doesn’t last forever, especially under stress - My 1999 D2 started to leak in August this year, I put 2 news ones in, 13 years, not bad. My 04 rangie doesn’t leak but all bags have the early fatigue signs (small cracks around the bellows that can be seen as the roll passes that point – sometimes not easy to spot) which could go another 5-6 years or could start leaking today. I would think 15 or more would be rare, most say 10 is it. If anything I would say higher Km would be better, as the rubber spends less time stuck in the one position. Some of the under used heavy trailers had significantly shorter bag life. Heat was also a factor.
Suspension bags are definately a consumable item, and to pair them with the strut makes sense.
Anyways - Gav, good to hear you're back in action.
No probs mate - just a friendly dig:). The $900 is for 2 complete strut assemblies with bags, delivered to my door - 28Kg's in all which I didn't think was bad, but not sure what others have found around the place. I did think about doing just the bags to save a few bucks, but as you said, the shocks will be about stuffed as well by now, so I'm looking forward to how it rides with brand new air bags and shocks.Quote:

That should keep things out of trouble for a while I think - the compressor was brand new when I bought the car 12 months ago, so that should have a bit of life left yet. Only the back bags and shocks to do at some stage. I haven't heard of the rear ones failing before, so probably no rush, but I think I'll do them sooner rather than later, just to put my mind at rest.

My EAS compressor was replaced at 150k by my insurance company following an accident as it co-coincidently failed during its stay at the smash repair shop. My experience with P38a is that it is usually the piston that goes although I was unsuccessful in getting the old L322 unit back - I was told that LR only supplies new ones on an exchange basis.Quote:

On my 2007 tdv8 L322 the dealer replaced last year (under extended new car warranty), the EAS compressor, a front strut assembly and a rear EAS bag and shock absorber. I suspect that it was misdiagnosis and as always the dealers replace parts as they are not paying for them.
It was like that with my P38a when I took it to a dealer before I purchased some diagnostic gear for myself. They told me all sorts of parts needed replacing at huge cost. I didn't believe any of it and purchased my own diagnosis gear - I found the problem was a little speck of rubber (probably from an EAS bag) lodged under one of the EAS valve seats causing it to slowly leak.
Daniel, the 2 systems are closely related.Quote:
