Please bear with me. I know this has been discussed multiple times before.

Last mouth I bought a 2022 seat leon. The car is amazing and drives so smooth. Everything is great except for the infortament system which is buggy / laggy.

The current software installed on my leon is Software version: 1803 Hardware: H56

According to seat themselves I should be on 1896. The issue is the car won't update OTA and I can't log in to become primary user. (it just gets stuck on the loading screen)

I've taken it into seat themselves today and they have said "we can't update it" we have no idea why it's not working. When we plug the computer into it, it's not even reading the car! (basically saying they have absolutely no idea what the issue is, they have never seen it before and told me to go back to Arnold Clark)

Arnold Clark have agreed to pay for this diagnostic as its within the 60 day warranty so luckily it's not costing me a penny.

The chap at seat looked online and he said the previous owner has never updated the car since day 1 so it's on the original software from 2022 out of the factory.

He suggested that maybe the car has been remapped and that's why the infortament software isn't updating and is incredibly slow / buggy. But they have no way of checking this so it's just a guess.


What are my options here? Should I push on for seat to fix it / replace what parts are required (although they said if it's proven that it's being remapped they will not help in any way shape or form and refuse to work on the vehicle)

Or just return the car to Arnold Clark and demand a refund.

The issue is the trim is the excellent lux DSG model so not hugely popular so I'd want a like for like replacement (if they agree)

Thanks
 
A remap wouldn’t stop the infotainment system from updating. A remap isn’t able to void the infotainment warranty or provide them with a reason not to touch the car. They’re talking out of their backside

However, bring it to us and we’ll sort it
100% this.

Even if it has been remapped (which a dealer can check and confirm), a remap, be it engine, gearbox or both will have no implications regarding your warranty on the infotainment system.

I'd find a more competent dealer.

DM me your VIN and I'll look into it for you.

Be warned Arnold Clark are among the worst dealers to reject a car to.
You can expect very heavy resistance if you demand a refund or replacement.
You may have more luck if you insist they pay for a repair and software update.
They may fight you regardless but a repair is better for them compared to you rejecting the car so they may do it to shut you up.
Also if you didn't remap the car yourself and the car is still exactly how it was when you bought it they can't refuse regardless (even if you had an engine issue) however they may still try to resist.
In regards to it not allowing the update this sounds similar to my car.
I had a specialist look at mine. They contacted Seat Technical who provided instructions on how to repair it.
Zero parts needed to be replaced on mine however It did cost a fair bit of labour. Lucky I work for the dealer who sold me the car and have the authority to approve repairs on behalf of my employer.

I want to be clear however, save your emails.
Keep a copy of what Seat told you
Make sure all further communication is in writing.
And most important tell your finance company if applicable.
If you're financing the car then the finance company may help you.

Fingers crossed for you to get this resolved, make them pay for it, you are legally entitled to this repair. also not sure about Scotland but if you are in England or Wales its actually 6 months they have to repair any issues. (Even after 6 months they have to repair any issues if you can prove the fault was present at time of purchase.)

Good luck.
Ps Dealers are useless for diagnostics. They don't like doing it. Find an auto electrician such as @East Yorkshire Retrofits however speak to Arnold Clark. They may have specific 3rd parties they like to use and they can legally insist on doing the repairs themselves or taking it to a garage of their choice. If you ask them to pay in retrospect they may refuse.
