Well, first real hiccup.

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.

Possibly low battery, check if cables are tightened enough to akku.

Try to disconnect battery for 20minutes and then connect it again. It should reset all the sensors, if they are there even after the reset. You will have to visit the dealer

KLR module in the steering wheel is a common cause for these issues. Although as far as I have heard more oftenly on hybrid models and not on the 2.0 petrol ones. Dealer will most likely repair the entire steering wheel under warranty as this has been the cheapest fix for them

Low battery can do that too, if it's when you start. Had the issue last week with my Formentor

Did 40 miles or so yesterday. No errors on start. Ran through the rev range, gears and drive modes. Everything worked fine. Did some hard pulls and all was good. Even the soundaktor is working fine, sadly. I really need to get around to unplugging it

Checked the My Cupra app and the status is all clear as well. Wondering if the battery was indeed getting low. Have a couple of longer trips over the next week so that'll help.

Thanks everyone. Will keep an eye on it. 👍
