Took the car out for a run last night and after 10 mins the traction control light and hand brake warning light both come on lit up yellow. Does anyone know we’re to start looking for the fault?
 
I have the same two warning lights... seems to happen more when its warm.

I know its an error of the dtc and dsc systems, but dont know where to start with resolving it. Should probably read the codes 🙄
 
It’s one or both of the pressure sensors on the master cylinder. Cheap and easy fix.
 
Daft as it seems, tap around the master cylinder under the bonnet with a screwdriver handle😉😉
It cured mine ages ago after reading the tip on here😄😄
 
Had the same last week - pressure sensors - two off eBay £30 - diagnostic pointed to pressure sensor 1, but replace both and saves the diagnostic. I couldn’t get the fault to clear initially, but after a little run, and switch on/off a few times all is now fine.

Have you got a link for the sensors?👍
 
Problem solved. It was one of the pressure sensors on the master cylinder. I got a pair off eBay for under £20.
Fitted it tonight, went a short run in it, pulled up, turned ignition on and of and the lights were gone👍🏻

I put a few pics up on PistonHeads a few months back:

Cheers, will do a bit more research as I am no brilliant spanner man,but don’t mind getting my hands dirty.
 
having just done the job, its a 27mm spanner you'll be needing, or, I found a 27mm impact socket fit over the entire sensor, and then a ratchet spanner to unscrew it.

expect some brake fluid leakage, make sure you have the replacement sensor ready to screw in as soon as the old one is out. also, gloves is a good shout, as brake fluid isn't the nicest stuff to get on your hands.

Really easy to do. Only took a minute and that’s with my 2 year old son helping😳 👍🏻

Is there anything critical I need to do or watch out for either prior or whilst doing this fix?
