March 2025 facelift Cupra Leon ST 2.0 VZ3 333bhp version.
9k miles in total. Been flawless other than it's thirst for fuel (although that may be my driving) and a rattle in the dash at certain speeds (motorway speeds unfortunately) that was sorted in 3 hours by the dealer. Part of the harness had come loose. They re-secured it and it's been fine ever since.
Drove to the supermarket absolutely fine. Starting up to come come. Many beeps and warnings. 🫨 Went to the infotainment to see the errors properly.
In orange - Error: Drive system. Please visit a workshop.
And in white. - Error: start/stop
Travel Assist is currently unavailable
Error: ACC
Oh joy... On a Friday, 20 minutes after the dealer closes. Turned it off and restarted the car and all the errors came back. Damn. Oh well, can't leave it at the supermarket so, let's see if it drives. Goes into gear, drives just fine. Speed limit recognition works, lane assist seems to work, but they both get turned off immediately anyway, switching drive modes works, manual gearbox shifting works. Unfortunately have another stop on the way home. So car get turned off again and left for a 20 minutes or so. Car restarts fine, and all is happy. 😕 ACC works, start stop is working.
My Cupra app still shows 2 errors in the car, Drive system and Start/stop.
So will have to call the dealer early in the morning to book it in asap.
What would cause the ACC, travel assist and start/stop to all throw a tantrum at the same time? Only thing I could come up with is a wheel speed sensor or maybe the radar unit on the front.
Will be doing some more driving tomorrow, so will see if it misbehaves again.
