ESC TSA REDUCED BRAKING ASSIST NOT AVAILABLE FAULTS

[R14ONE]

Hi

I had the following faults all at once this evening which would not reset after three stops and restarting.

ESC not available
Vehicle stability reduced TSA
Hydraulic brake malfunction
Downhill Assist not available
Uphill Assist not available

Has anyone else had the same faults at same time?
Possibly of wiring fault or software?

Thanks

Has your Grenadier been modified?

This is a VERY common electrical issue. Will not hurt your car, but you will not have those functions available. Most of the time, a simple off/back on iginition will clear it (as in engine off, key removed, back and start it up. I get this alert about 1x per week since ownership (not yet had it back to dealer for that issue but it is on my list!).

Take it back in. It’s definitely not common. Maybe some sort of sensor issue with the brakes. It sucks when this happens to a new car but bear with it, once all the niggles are sorted it will be awesome.

Thanks for your message. The faults are now coming up on every journey. I will book it in with a dealer. We have a large road trip soon.

I had all of these come up one time last week. They'd disappeared by the next time I used the vehicle and haven't appeared again since. I suspect it's caused by a wheel position sensor error.

This happened to me on a long 1000km stretch crossing a cattle grate whilst with cruise control engaged. Error would clear after restart but returned after about 20mins. The next day on an equally long stretch never came up again. Spoke
To the agent and he thinks could be related to the wiring harness behind steering wheel. Apparently there is a campaign to fix this at the moment.

Hi,
Thanks for your messages.
I had a four wheel alignment carried out today. The steering wheel angle and tracking settings from factory were incorrect. The faults have now cleared. The steering wheel is now straight as it was originally cocked at 1 o’clock when driving straight.

Cheers

All this time and the factory can’t align a steering wheel or geometry correctly. I really don’t understand why.

Mine had the TSA warning today. I was sitting in a parking lot idling. 400 miles on it.

I just had the TSA not available WM amber warning come up on my drive home tonight. I was driving straight at about 35mph. Anyone know what that one is all about?

I hit 4 mud holes and a large dirt road puddle intentionally yesterday and got a bunch of these. Haven't tried to restart. My rear right wheel is packed with mud (now dried) and I just assumed the wheel sensor is probably dirty / muddy. I was going to wash it and maybe carefully powerwash the wheel / hub area and see what happens.

Reduced braking, TSA, AEB, etc.

I had all these messages and a few more. Turned out to be a stone bending one of the teeth on a rear wheel speed sensor. Happened on a rough track. Still waiting for confirmation that it is a warranty issue. Should not be possible given the design brief. What do you think?

I have had those same faults routinely, trying to work with the dealer to remedy.
