Next problem X308 XJR

[Zippyworld]

Bloody hell,with the money I have ploughed into this car there cannot be many things left to go wrong...

I have an amber dash lamp on with Suspension Fault message....

I am thinking I Need to get this professionally looked at but any input would be appreciated please.

It comes on pretty quickly when the cars ignition is turned on.

You've had such fun and games with this car now that you obviously realise that a code reader is the first tool to pick up when you have a problem.

So what codes have been generated this time?

[Zippyworld]

Errrr. Pass.

I did buy one once but lent it out and never saw it again.......ho hum

[Sebring440]

OK, we'll leave it at that, then.

Has anyone anything constructive to mention regarding what my potential issue could be please, I am not looking fir a diagnosis here, just ideas on what the problem could be and how deep I could be digging into my cash pot.

Have you inspected closely the connectors to the damper tops? Assuming that your cats system is the same as my Daimler Super V8, one of the wires to those connectors could be damaged.
Another worthwhile thing might be to disconnect the battery for an hour and touch the two terminals on the car together to dissipate any charge. Then reconnect those connectors to the battery and see if the error message goes. Make sure you know the radio code first and you will obviously lose any trip info.
I haven't followed the damper wires to see if they have a connector somewhere but if they have, they too would be worth a look at,

Thankyou for this, yes I believe they are similar set ups, bloody fault cleared this morning on start up ha ha.
If thefault does not show up on the display I am wondering would it show up on a OBD Scanner ?
I do have a basic one as a spare which gave nothing.

I will have a look around as you suggest and if Ifind anything will report back

I think some of the faults are not logged if they occur and clear by themselves, less than a certain number of times so they may not be visible to a scanner. For some reason during my very recent Supercharger elbow leak, running like a bag of soot at tick over but fine otherwise, did not log a fault, even though I had the Restricted light on at one point in traffic but no Mil light ever - that disappeared never to return.
As these cars of ours get older and connector resistances are raised by surface corrosion, I think unfortunately we will see more of these frustrating messages. It seems to me that the parameters for sensor tolerance set by the software engineers, although fine when new, just might be a little too tight as age plays it's inevitable part.
Off to buy a Moggy Minor 😄

You've also got to have a fault that the ECU is programmed to catch! I had a Range Rover TDV8 before, something went wrong one day coming down the motorway and the car was running like a dog with black smoke belching out the back, was barely able to rev below 2000rpm . Not a single error code or light triggered. The garage were stumped and only found the problem when starting a strip down. It turned out to be the valve head in one of the EGRs had snapped off. The valve was still operating normally as far as the ECU was concerned, but obvioulsy not actually doing anything with no head on it.

Also, I managed to crack the EGR pipe on my XKR when I was swapping out the supercharger the 3rd time, no error codes or any drop in performance maybe just a slightly rough tick over and I could hear it 'pinking' or 'knocking' when cold. Took me a week or so to suss that one out.

With regards the OP, intermittent faults likely to wires loose, my current Range Rover has the electric suspension control and the wires into the front driver strut were stretched and broken when I first got the car. Took 10 mins and a soldering iron to fix properly.

Dodgy cable going into the top of left hand damper.....phew
Little bit of preventative tin worm dining completed on front sills while it was in, just a small job.

Dry weather please.....
