All warning lights on

MRO said:

Love to get any advice.

After driving up and down a rough track which required all diff locks, bellying out in peat and getting quite thrown around, all my warning lights seem to have come on. Messages are ESC and ABS not available, downhill and uphill assist, power steering error etc.

Was impressed with how it did on the track.

Drives fine.

Have called the AA but I am a long way from civilisation.

Had a similar thing with a lot of very short stop start trips in 1 day (rubbish tip runs) 1/2mile max. All lights on no speedo. Rear camera stuck on, had to turn off manually.
Short run and restarted and all cleared. Could be just a glitch? Never happened again but I've not had to do the same journeys in 1 day since. As they were all warnings rather than red I didn't worry---too much

Those lights are all amber. Personally I’d drive that home. And then to the dealers in the morning if the lights haven’t gone off. Have you lost power? I’ll be interested in the feedback on this one.

Home is 735 miles from North Coast Scotland to Devon. I probably will but it is a decent hop home.

OK. Stirling Trailer Centre - Ineos Service Partner - absolutely brilliant. Sarah-Jane..... Baron Von Teuchter speaks highly of somewhere in Huntly, and I've seen mention of somewhere in Dingwall?

Thats assuming that turning off. locking up. Go for a coffee. and then try again doesn't re-set the system

I'm sure I saw an Ineos garage in Inverness

Local mechanic diagnosed a rear left wheel sensor issue. Why does every warning light need to suggest every major component on the car is about to explode? I think Ineos has fallen victim to the usual nanny state rubbish rather than choosing this themselves. Can we have a button that switches off nanny?

I had a similar problem. I caused it myself by mucking around with too many buttons and stuff just seeing what does and doesn’t work. Obviously the grenadier wasn’t broken!

I bought the innova 5110 diagnostic device on Amazon. It arrived in a day and took me all of 2 minutes to diagnose no issues and clear all the codes! It is was simple! Here is a photo of it. Worked like a charm.

Glad you have a solution.

Not to dismiss your annoyance, but amber lights indicate degraded performance. There was nothing in that light stack that was stopping you from driving home. That's my hindsight from living with this vehicle for a while.
With the exception of the power steering error, which is the odd one out, those other systems all rely on the wheel speed sensors for correct operation. It's not just Ineos. I have seen a few other big brands throw errors after a wheel ring (ABS ring) was damaged or full of mud. I had a Hyundai that would throw an ABS error after driving through a puddle if water splashed onto the wheel ring.
Where Ineos are making it hard is in their custom DTC codes. Talking to my dealer recently they had a similar issue with a vehicle presented by a customer who had completed a big off-road trip. The DTC code was meaningless, but their experience told them to check all the wheel rings. Sure enough, a stone had put a dent in a ring so the gaps between two adjacent segments was no longer symmetrical. 3 of 4 rings were giving valid wheel speed data but the damaged ring was generating the wrong frequency because of the gap variation. That was enough glitch to send all dependent systems into an amber melt down. This looks dramatic on a Grenadier because there are many reliant systems, mostly for off-road assistance.
