unclebill1 Posted August 5, 2007 Share Posted August 5, 2007 The infamous P38 air suspension, going down the motorway today, suddenly get EAS up on the dash, maximum speed 35mph, now the suspension looks to me to be inflated and the compressor is running OK, even opened the tail gate to deflate the suspension and it lifted itself againg, a bit jerkily I admit, tried disconnecting the battery to reset the electronics, no luck, before I phone the garage is there any quick and easy way to reset the electronic thingany wotsit, Help anyone cheers Bill Quote Link to comment Share on other sites More sharing options...
Jon White Posted August 5, 2007 Share Posted August 5, 2007 Absolutely nothing you can do except pay the nice man with the computer lots of money to plug it and tell you whats wrong with it! Only other option is to convert it to coils (which may be cheaper than fixing the air suspension) HTH Jon Quote Link to comment Share on other sites More sharing options...

Projectblue Posted August 5, 2007 Share Posted August 5, 2007 I suspected that, ah well, could be coils soon then. Don't jump too soon. There can be some simple reasons for the air suspension to play up. Sometimes the fault can be rectified for the cost of a shock asorber. It's not always doom & gloom (although most of the time it is ) Have a chat with your local specialist before consigning it to the bin.

Jon White Posted August 6, 2007 Share Posted August 6, 2007 Once its got a fault code logged though the only way to clear it is via the diagnostics! Jon Quote Link to comment Share on other sites More sharing options...
David Sparkes Posted August 6, 2007 Share Posted August 6, 2007 unclebill, In general, if you end up paying other people to look after your 38A it will be expensive. If you have that disposable income, great. If not, you have to find out how to look after it yourself, so go to to the Rover Renovations site and read up his instructions. As well, have a look at the rangerovers.net site. Cheers. Quote Link to comment Share on other sites More sharing options...
geoffbeaumont Posted August 6, 2007 Share Posted August 6, 2007 Once its got a fault code logged though the only way to clear it is via the diagnostics!Jon Despite it's reputation, this is the only really major flaw with RR air suspension (at least classic/P38a, which are fundamentally the same system - I'm not familiar with the later ones). It's quite straightforward to work on and parts are no longer cripplingly expensive. Coils are all very well if you only use your vehicle for one thing, but if not they aren't ajustable and you have to compromise a lot more than you do with EAS.

Agree, and unfortunately nobody has made an affordable DIY diagnostic system for it. IMHO Rovacom is not affordable, especially when compared to the cost of a coil conversion. I have found, and solved a number of problems with the EAS on mine, using nothing more than the wiring diagram, and a multimeter. However there is no way to recalibrate the height sensors without diagnostics, and there is no way to clear the error codes without diagnostics. When you consider that ABS is made with a built in diagnostic, I think its inexcusable that they didnt include the same on the EAS ecu!

geoffbeaumont Posted August 6, 2007 Share Posted August 6, 2007 I'm with you there - along with a friend I looked into what it would take to build a DIY diagnostic interface for the EAS. We came to the conclusion that there's a good reason why the likes of Blackbox charge a fair bit of money and don't have many competitors - it's a lot of work reverse engineering the comms! Even just the ability to clear error codes would be a huge help. Quote Link to comment Share on other sites More sharing options...
Jon White Posted August 6, 2007 Share Posted August 6, 2007 To be honest I actually reckon it'd be easier to build your own ECU from scratch for this purpose. There isnt that much to it really! Jon Quote Link to comment Share on other sites More sharing options...

He's a bit miffed I've sold the truck he was going to use as a test bed, though Quote Link to comment Share on other sites More sharing options...
