Warning lamp

[ERIC3451]

A yellow warning lamp has just appeared in the instrument cluster of our 2013 Leon Mk3 1.4 SE Technology. The warning light is showing continuously. (not flashing)

The lamp shows a yellow outline of an engine block and the user manual (looks more orange to me though) states that this shows a "Fault in the emission control system".

The car is driving perfectly normal with no unusual emissions from the exhaust.

The car is due and booked with my dealership for a minor 3rd year service next week.

I have read that this might be down to a faulty or loose oxygen sensor and that the fact that it is not flashing is good in that it only indicates a minor fault.

Has anyone else experienced this or can anyone advise me as what I should do in the short term?.

The owners manual is pretty useless for diagnosing this fault. Warning lights which are Red are the major faults.

Have you tried turning the car on / off a few times to see if the fault clears itself? If its driving normally and its booked in next week then I'd prob speak to the dealer now to see if they can shed any light on the problem and get them to look at it ASAP.

Out of curiosity, which dealer is it booked in with for the service?

 

[ERIC3451]

One of the first things I did was to try turning the car on and off, but no joy. Tried again when car cold, but warning lamp still up.

Have brought my service forward to tomorrow Friday 19 August. Taking it back to Agnew Auto Exchange Ladas Drive where I bought the car as new, and had the car serviced in past two services.

The error light won't go now until the fault code has been erased. Tomorrow the dealer should be able to get a fault code which should tell them what's wrong with the car. I assume it's still under warranty since its having the 3rd service now?

Yes it is still just within the 3 year warranty which ends on 24 Sept 2016. I have had it serviced at the Seat Dealership according to "Seats UK Warranty recommendations" during its first two services.

The service it is currently booked in for is the 3 year minor which, according to Seats service schedule, will just be "serviced to Seats UK Recommendations" (no mention of "UK Warranty recommendations" since at the 3rd service it should be approaching the end of its warranty.)

Might this be covered under the warranty, or is it possible that any repair/replacement could be put down to wear and tear?

 

[Jarre]

Without knowing the fault code I couldn't give you a definite answer but I'm almost certain it'll be something that will be covered under your warranty.

Its likely it will be covered under warranty as emission control system is not something you could really mess up. Hopefully it will just be a sensor.

Would be different if it was something like brakes or suspension which do wear out so they generally aren't covered under warranty.

Update us tomorrow with what the fault was - probably good it has happened now and not just over a months time when the car will be out of warranty.

 

[ERIC3451]

I should have mentioned that I did remove the fuel cap and replace it again, but the warning light still stayed on.

Couldn't get a good inspection of the cap at night (its secured with a line), so will have a better look tomorrow to see if it is cracked or damaged.

I would think faulty o2 sensors, or mass airflow sensor should have fault free operation for the life of the warranty as well, although these things can fail through use overtime.

Either way I will comment again after diagnostic checks at the dealer.

 

[chrisRibiza]

So what was the diagnosis?

 

[ERIC3451]

Faulty O2 Sensor diagnosed and covered under the warranty. I think I was quoted the No1 O2 Sensor !?.

Part ordered and appointment made to fit it next Wednesday. So hopefully that will do the trick.

Don't feel any difference in that car seems to drive fine and warning lamp is only indication that something isn't right. Been told that it is OK to continue to drive the car in the meantime, so hopefully no harm to cat.

 

[ERIC3451]

Ops!. Started the car up to reposition it on the drive and noticed the warning lamp has gone out. It still lights on start up and goes out along with the other warning lamps as is normal.

Haven't driven it any distance yet, and probably won,t until Wednesday when I take it back to the dealers workshop to have the O2 sensor replaced.

 

[chrisRibiza]

The light will go out after a couple of restarts if no fault is detected, that's why I wondered if you tried turning the car off / on a few times originally.

Still worth getting the sensor sorted now while it's still under warranty.

I had the yellow emissions light flashing on my ST a few months back, along with a message on the MFD that said 'Start/Stop: Error'.

The RAC said it was a 'Cylinder 2 misfire' according to the code. Then on the third restart it totally disappeared, all returned to normal and it has never played up since. The dealership took a look at it and couldn't find any fault to rectify.

I just put it down to gremlins and forgot about it to be honest, there's so many gizmos on these cars nowadays it's hardly surprising they play up. It might just have been a bit of crud that made its way past a sensor on its journey from the fuel tank. I wouldn't worry unduly, in my experience SEAT aren't too bad with warranty work (although I know others complain).

 

[ERIC3451]

The warning light did not reappear before taking it back to the dealer. Got the Bank 1 Sensor 1 replaced under the warranty. All will hopefully be well from here in.

 

[ERIC3451]

Just as it did last August the"Fault in the emission control system" yellow warning lamp has just appeared again (outline of an engine block). Back then the No1 O2 sensor was diagnosed and replaced.

Off to the dealers again for a diagnostic check.

What with faulty rear light units and a repeating emission control system fault- VERY DISSAPOINTING

 

[ERIC3451]

Dealer squeezed me in for diagnostic check and Bank 1 O2 Sensor, that was replaced in August, was again diagnosed as the fault. Seat dealers workshop sceptical that this is the problem, probably because the warning light inexplicably cancelled after the diagnostics.
Booked again for 3 weeks time to further investigate. In the meantime will have to wait to see if the warning light stays out.
Anyone else have a similar experience?

If it's the same one you had replaced the parts should have 12/24 month guarantee on them as a starting point

Good point marty_34.

I was thinking along the lines that it was an issue that happened within the 3 year Warranty period, re-occured (not satisfactorily resolved) and still would be considered under the original warranty.

Problem is though the dealer has not yet recognised that it is the Bank 1 O2 sensor again, and has booked me in for more planned investigation, before taking it any further.

Parts replaced under warranty do not get the same cover as ones you pay for, They are covered to the same point as the OE ones, ie after 3 years old the car is out of warranty. If serviced within the dealer network and a part fails early but out of warranty a goodwill gesture of free replacement is quite common.

 

[ERIC3451]

I didn't know that Seastormer.
Important that I realise that it is an issue of goodwill on my dealer or Seats part . It will influence my attitude with my dealer in that goodwill is in play here and not a contractural or consumer right that I have.
