Multiple simultaneous warning lights

[cowgoesmoo69]

2015 T6 Highline. Was driving along a couple of days ago when multiple warning lights came on simultaneously.

TPMS light was flashing with a message on the screen saying something like TPMS currently unavailable. ESC and ABS lights solidly on.

Also saw a message on the screen saying auto stop/start was unavailable, and indeed I came to a stop somewhere safe and put it into neutral and it didn't stop. Had a quick look around it, couldn't see anything obviously wrong.

After a few minutes, all the lights disappeared and everything went back to normal. It did it again about ten minutes later on the same journey.

I gather this is most likely one or more wheel speed sensors? Would that also affect the auto stop/start?

I parked up overnight and it did the same when I started it for the first time yesterday morning, again sorted itself out after a couple of minutes. Drove a few hundred miles home in the afternoon and it was fine the whole way

Will I see anything if I put my basic OBD reader on it? I'm guessing not because the check engine light isn't illuminated indicating there's a stored error code to look at. Presumably I'd need something a bit more advanced that can actually interrogate modules rather than just seeing pending/stored codes in the ECU?

Wheel speed sensor probably.

It has memory and will recall the fault code, you should get enough info to know what wheel is the cause

cool, i'll plug it in later and see if there's anything there.

I had exactly the same a couple of weeks ago;

Yesterday I got the unwelcome ABS / Traction control / TPMS amber lights on the dash - which suggested a wheel speed sensor failure, it would come and go, so not likely chewed wires.
Local garage couldn't fit me in for two weeks but very kindly, and for some beer tokens, offered to code read the van for me as soon as I could get there.
It showed rear right wheel speed sensor failure so I popped to a nearby motor factors and picked one up.
It's a bit of a faff getting the old one out and I ended up shearing it off then driving a wood screw into the remaining bit and using a claw hammer to pull it out.
Anyway, job's a good'un, the lights all went out within 20 metres of driving out of the shed.

If you can identify which wheel speed sensor is the problem it's a fairly easy DIY job.

I had the same a couple of months ago and yep, it was a wheel speed sensor so hopefully an easy fix for you
