My Range Rover Sport keeps going into limp mode

Hi everyone, I’ve recently bitten the bullet after years of pining for a Range Rover Sport and traded in my much loved but outgrown focus for a Range Rover Sport. I found a dealer fairly local to me and got a really good trade in for my focus. The Range Rover is 2009 2.7 with 84,000 on the clock. It’s came with a years Mot, service, 1 years breakdown cover with the AA and 3 months warranty. The car has been well looked after and in immaculate condition. Ticks all the boxes for us as a family, safe, higher up the road, bigger boots space for all those football matches and holiday trips etc etc. Anyway it’s been a pleasure to drive until 10 days after I purchased it. I knew buying a Range Rover meant higher running costs and I had heard about the electrics but I didn’t expect to have the engine failure message come on whilst driving home yesterday. Range Rover went into limp mode and poodled home at about 30mph. When I pulled up on the drive I switched the engine off and restarted. The error message was gone??. I driven in it today several times and it’s gobe into limp mode again. Again I pulled over restarted the engine and the messages disappeared and car was restored to full power again? So basically no error codes are being stored and vehicle seems to correct itself on a restart. I can’t however cope driving like this it makes the car feel unreliable constantly worrying weather I will make it from Ato B. I’ve contacted the dealer and they are more than happy to take the car in and try to get to the bottom of it. Trouble is they said with no stored error codes and it happening intermittently the Range Rover May perform perfectly whilst their mechanics are in receipt of it? Any ideas or thoughts on this? Took a photo whilst it was in limp mode earlier.

Hi Marnie, Welcome to LZ.
This section is for the "Hi, this is my beloved Landie, and here are my Pictures...." etc. etc.

The Rangie section for asking for help and avice is over here.... https://www.landyzone.co.uk/forum/range-rover.10/
Just copy and paste your stuff above in a new thread there for maximum exposure to RR junkies who can help.

As above and welcome...get dealer to put it on diagnostics or get them to come out when fault occurs...

Hi and welcome

Op has indeed done a thread over in the rangie section

Thank you for all your suggestions and making me welcome on this forum. Just a quick update. I took it back to the dealer and they had their own mechanics on site test it. They put a diagnostic machine on and there was no stored faults, they tested the battery and apparently the battery is on its way out hence all the random messages and faults popping up. It’s seems strange a battery would cause all that. Anyway they are ordering me a new battery.

All Rangies (but especially the newer ones) really need batteries that are in tip-top shape.
By all means get them to replace the battery and see IF your issues go away. If not, then at least it is one item you can discount as the cause of trouble (maybe).
Good Luck.

If I’m honest I think it’s a load of B@llocks. I’ve been told that all codes whether they disappear or not should show up on a code reader. So either their code reader is broken or they are wanting to keep repairs under their warrenty to a minimum. The latter being the case. If I pick the car up tomorrow and it goes into limp mode again then like you say at least I can eliminate the battery. What I will do is take it to a garage that specialises in Range Rovers get the codes and take it back to the dealer insisting that ever code is investigated as it’s more than the battery.

Battery can cause this issue if dying, not uncommon even for my 1995 model.

The gearbox, engine, alarm/immobiliser - everything is connected with bloomin computers. LR seem to have this way of interconnecting them so if one goes .....domino.
Kills Batterys as they are active even when not running. This is why no RR likes being stood for too long or driven short runs only.

If you ever you get a code read with diagnostics - get the actual code ; not their interpretation of what it means

removed as I forgot it was the intro section
