Hi,

RRS TDV8 had the common seen yellow suspension light come on. Very intermittently though. At this stage could raise and lower suspension but noticed on screen red access on passenger side front wheel so possible height sensor? Took to garage, they checked compressor, airbags, valves and said could not replicate the red access on the screen so did not replace sensor but I believe they recalibrated it. They said could find nothing wrong. They raised the suspension to highest setting and left to see if any leaks.

When I went to collect, it was still at highest height, I could not lower it. Red warning light. Putting aside I had been told it was ready for collection and it was fine, the garage drove a short while and the suspension returned to normal, but then striaght away the red suspension light appeared with the 30mph warning. The RRS however appeared to be driving normally but the suspension could not be raised or lowered.

Today a height sensor has been replaced but garage has stated it could not be recalibrated because the red warning light is still on? The suspension still cannot be raised or lowered.

The battery has been checked and the rear brake light switch. All are fine.

The diagnostics I am told show an ECU fault. They have tried to clear the faults but cannot.

Car still in the garage. It is not a LR garage but have serviced etc RRS for a number of years. They are in contact with the local LR dealer (who used to service the car) and they are saying it may take 2 weeks to find out what it is!

Any ideas would be very welcome. Many thanks in advance

Can you post up fault codes?

Have you got active headlamps, dynamic suspension etc on this model? 2012 5.0 SC AB

Thank you for the reply. Only fault I know is the garage has said ECU, so no codes sorry. I did see them put the diagnostics on it when I went to collect it the first time, and did see them try to clear the codes and only bit I could see on the screen said something along the line of "unable to clear".

TDV8 2008 model.

Apologies for lack of info other than in my original post, it is my car but hubby tends to deal with all the techinical side of it, he is away at the mo so I am totally beholden to the garage. I wish I had kept driving it with it's yellow warning as obviously now it appears to have more issues than when I took it to the garage.

Thanks for ongoing help.

They can't clear the fault code or codes because they haven't cured the fault. Leaves a lot of scope for them to just say ECU fault, without fault codes very difficult to advise as there are a awful lot of different codes go with the eas.

It’s only a suspicion but the ECU fault maybe down to the suspension fault. The ECU may restrict to 30mph due to the suspension fault but may not be directly faulty. There are some good Techies on the site who im sure will come along but I would think the garage don’t have the kit or knowledge to sort this.

I know from previous experience that issues with the active suspension and active lights can give you suspension problems that you would never think to be related.

I will guarantee there will be some fault codes but they maybe don’t have the right diagnostic kit to access them.

On a tangent, where in Cumbria are you from? I was born in Penrith but brought up in Kendal. 2012 5.0 SC AB

after a calibration on an IID, you need to re-enable the system, otherwise the red light stays on

Thanks everyone for their replies. I have left the car at the garage to sort it out, but from the replies I am wondering if it is best to take it to LR, used to have it serviced at Coniston LR, unless anyone can offer any alternatives even if I have to drive there at 30 mph all the way!

Brit Plumber we are a few miles from Keswick.

Andy K, you say the system needs to be re enabled - is this something LR have to do, and could it be (being highly optimistic!) that this could clear the red warning light and all will (may!) be well now the sensor has been changed?

Is the fact the suspension cannot be raised or lowered, just a chime when trying, a restriction because of the red warning light being on, so if the warning is cleared, raising or lowering the suspension then becomes available?

Thanks for everyone's continuing help.

I think you may find being unable to lower or raise the suspension is a sort of default mode if there is a problem, I would have though the only way to clear the warning is fix the fault.

Thanks again for your replies, proving helpful as it gives me more information to try and make a decision as what to do next.

Apologies for the questions again, the garage said on Friday after changing a height sensor they could not recalibrate because with the red warning light on " it says not to recalibrate". I am not too sure what the "it" is? As, from everyone's helpful replies, I now have a clearer understanding of the suspension being in a default mode and possibly why there is an ECU fault showing, do I let the garage recalibrate tomorrow even with the red warning light? My concern is, as Andy K has said, the car has twice been to the garage and all they have done is change a yellow warning light to red.

So my options appear to be:
1. Ask garage to recalibrate tomorrow and see what happens
2. Go to LR Coniston who may just do as above?
3. Go to an independent LR garage - has anyone used Kmotors, Leyland or Simon Huntingdon in Wigton or Mastora in Alnwick?

Thanks again

It’s probably a wording issue here. I doubt it says ‘Not to calibrate’ but more ‘Could not calibrate’ meaning there is still something to resolve and therefor it is not possible to calibrate. 2012 5.0 SC AB

Thanks Brit Plumber, that is a very good point and a question I will ask first thing in the morning when I speak to the garage. Although if it is could not calibrate that does dispel my thought that recalibration may be all it needs!!

Not necessarily, it could be the way they are doing it or the measurements they are entering are outside of parameters. If they use the default values for a Range Rover rather than a sport for example. 2012 5.0 SC AB

Once again thanks for the quick reply that helps explain further, I will ask for more info on exactly why the calibration didn't happen on Friday, in the morning.

Do you happen to have any suggestions of anywhere else to use if I decide to not let the garage keep the car until they fix it?
