updates of my beloved 2016 Leon FR

I added bigger brakes, coilovers from ST Supsensions and a bigger wing! Also changed the front lip and had some work done on the front axle! Many upgrades are OEM Parts from within VAG!
Wish I could slap a 5 Cylinder in this!
First is the most recent, last is the oldest!

Seat Leon mk3 2.0tdi 184hp losing coolant

Hi, I bought My 2014 seat Leon mk3 2.0 Tdi about a year ago now, been a great car in general and have had few issues other than burning some oil, and mainly randomly losing all my coolant, it’s happened 4/5 times now where I’ll go to start the car in the morning and the reservoir will be empty, it’ll usually only need topping up of about 500ml to a litre and it’ll then stay that level exactly only to dump another 500ml a few months later, I’ve had it checked out by my mechanic who says he can’t find what’s wrong, another mechanic told me it might be the water pump but that was done only about 50000km ago so it shouldn’t really be causing trouble, this hasn’t ever really bothered me that much because the car still drives perfect and never overheats but I’m thinking of selling the car and don’t want someone to be stuck with this issue, the radiator fan also sometimes stays on very very loud after I turn the car off, I’ve had people come telling me I forgot to turn my car off when it’s actually just this fan that occasionally stays on for 3/4 mins after driving

Digital Cockpit upgrade

I currently have an analog cockpit and looking to swap to digital, but I’m finding it extremely hard to know if the part is suitable. On paper I think it is, I have a 2019 Seat Leon FR 5F Auto, the digital cockpit is labelled as 2017-2020 5F0920790A Seat Leon FR. Does anyone know if this will fit into my car?

Thanks

Liquid leak seat Leon 2016

Hello , I am far away from home , i saw a leak under the engine part , looking to the level of the cooling liquid it went a little under the MIN level after hours tha car raised an error about it.

Going back home in 2 days (500km away) , i will just add to max level and check it every hour to add more if needed.

Do you think this is safe ? I'm in an empty area where finding a good mechanic is impossible! So i want just to arrive home safe and make the checks with my mechanic.

Thank you

MIB3 SEAT/CUPRA MOI3_EU_SE_R9400L_MU1940_575919360AN – Stuck in Red Menu after firmware update

I hope someone here can help me with a MIB3 LG issue.

I was in the process of updating my infotainment unit from:

MOI3_EU_SE_R7800L

to:

MOI3_EU_SE_R9400L_MU1940_575919360AN

This is my first time updating one of these units, but before starting I spent around 50 hours learning about the system through YouTube, Reddit, forums, and other sources, so I tried to understand the process properly before attempting the update.

Unfortunately, when I reached the actual update process, it started failing on some of the files, and now the unit is stuck in the Red Menu.

I am now unsure what the correct next step is.

I have tried searching for a solution, but I cannot find anyone with exactly the same issue.

I would like to ask people with MIB3 experience:

  1. Has anyone experienced errors while installing:

MOI3_EU_SE_R9400L_MU1940_575919360AN.7z

from MIBSolution?

  1. Is there a way to recover the unit from Red Menu using a correct firmware package?
  2. Is the problem caused by the firmware file itself, or should I have followed a different update path/version sequence first?

I understand that I may have missed something, but I really tried to prepare myself before doing the update.

Right now, I am honestly very frustrated because I managed to get this far, and now I am stuck without knowing how to move forward.

Unit information:

  • SEAT/CUPRA MIB3 LG (MOI3)
  • Starting firmware: MOI3_EU_SE_R7800L
  • Update attempt: MOI3_EU_SE_R9400L_MU1940_575919360AN
  • Current status: Stuck in Red Menu

I would really appreciate any help from someone who has experience recovering a MIB3 unit from this situation.

Thank you in advance.
