Is my car a lemon or are 92 faults normal from OBDevelen?

[jeeeefff]

I've just brought a OBD11 pro out of interest as my recently purchased 2021 Seat Leon FR EVO 1.0tsi has had quite a bit of issues.

My initial aim was to find out the OCU version to see if it's due a firmware update in hope to rectify SOS, pop clicks and sat nav issues so I can bring it up at a possible future SEAT service.

However I was a bit shocked to see all these faults and wanted to know if this is normal or should I consider returning the car and not go through all the hassle or if this was the norm for these cars.

I'll have a deeper drive into these error codes in detail but wanted to know if its worth clearing them to see if they resurface and see it they were just old issues or leave as is for future reference.

Thanks for any advice and help on the matter.

 

[jeeeefff]

After a bit more investigation on my part, running some searches on passive errors and from what I understand, clearing all those errors via OBDeleven app seems perfectly safe, in doing so I've reduced the errors down to 4 Red errors, mainly to see if the passive ones I've seen before and have documented happy again.

I'll slowly look for the passive issues should they fire up again.

According to my OBD11, should this be of major concern?

I've seen this from an Audi forum, will compare to see if they are similar:

This is the log before I cleared the error codes but doing some quick looks at the passives I've seen some known fixes i.e. the window one being holding down 10s, then holding up 10s.

This car does high mileage discrepancy but I'm hoping its mainly down to major user input error and OBD11 mileage check paints it more inline with what it says on my dashboard but i'm happy for any advice should it might have been tempered with. It certainly doesnt look like a car thats done 81754 miles condition wise, inside in out. Very happy for advice on tips and if its even possible for me to correct this record if its legit and correct.

The norm has been to not have any errors anywhere.
In my experience VAG cars, 2020 and onwards, tend not to follow this ideal.

My 2021 Leon shows lots of databus missing message, databus invalid message entries as well.
Some Audi A4 I recently checked: something regarding Ethernet.
All this in various control units, they randomly come back after clearing, without any noticeably issue.

In your case, it looks like battery was low or disconnected.
Check which errors come back after clearing.

thanks for chiming in @leonmax96, yes this is how I see it with my limited experience with older cars. Still a learning curve. After doing more digging I think passive errors are fine to clear but will keep tabs if they keep coming back.

I've tried 3 times last night to clear errors and once again just now. It seems like I keep getting the same 7 red faults after each drive upon clearing. Will try a 4th time to be sure and post here what they are shortly

 

[jeeeefff]

I was getting the same 7 red errors, I attempted to clear just now, battery seems green and fine according to the ODBeleven VAG app. After Clearing just now it did warn of a much longer read time, saying hrs as it was attempting to scan 233 things, I did let it sit for 15 mins but was nearing the end of my break. I will let it run the whole way through when home, is this normal? my previous clears last night didn't seem to result in doing a full scan that long.

I does say no faulty control units but just show up as red with fault codes and seems same thing each time I do clear the codes

a pic of it scanning 233 things:

will past the report shortly if it helps

[cairus]

In my experience this is unfortunately normal for MQB EVO

 

[jeeeefff]

That's a little more reassuring to know if that's the norm, Thanks for letting me know @cairus. I am keen to keep the car and wasn't sure about how safe it was long term as I'm not only driving myself but family too.

So those red errors aren't something I should stress over and consider taking to a SEAT garage for? I'll try to let it run the longer scan later tonight.

 

[cairus]

The question is, what errors are left after deletion?

 

[jeeeefff]

The question is, what errors are left after deletion?

ah good shout. I will find out soon after work when I have more time to allow the full scan to run, I think the app warn it could take hrs. I will try though

 

[jeeeefff]

Back again, this is the report after clearing all error codes, I've removed things that say 'No trouble codes found' and only posted the trouble code parts in hope it makes it easier to see. Im going to cross-check with older logs to see if its always the same thing, for now it looks that way. Only this time I'm seeing more null things in 75 Telematics:

OK, I wouldn't ignore some of these errors anymore. The car drives without the warning light active?

 

[jeeeefff]

Hi Cairus, Thanks for the wise warning.

That's right, no yellow lights on the dashboard or even when looking for car alerts on the touchscreen unit, I was trying to look for the section for warning alerts but assumed because there is non I couldn't find it, nothing popped up even short drive:

The only warnings I do get are intermintant, seem to happen when using andriod play for navigating, sound pops, map freeze, SOS yellow warning lights. This has happened once so far on short errand runs and 4 times now on longer 30+ min drives. The info unit did randomly shut off too once, then boote back up. Apart from these issues, no other warnings both on the dash or in the info screen. Operates normal too.

 

[jeeeefff]

Just making a note of errors prior to clearing all codes, just car on, not engine, keeping only the error parts:
