Help please… misfire detected

[Blue2021]

Hello, I’m new to Skoda (not cars though and have had many different makes and models) having bought a fabia one month ago. Yesterday I had engine light come on, with juddering and a strong smell (burning/eggy… my sense of smell not good but was v string). Took it back to sales point, ran diagnostic check (but didn’t provide me with a copy, but I did get screen shots of errors P030000, P030100, P1300A00) then they cleared messages. Returning car to me they said can’t do anything as no warning light/errors on dash when they took it (the engine was still lit). I’m not happy as reading here I think they should have at least checked spark plugs/coil… they said as no warning lights they won’t do anything… but they cleared them! Leaving a very bad feeling that I’ve been sold a dud (never had this before) car is 2018 (month out of manufacturing warranty) and has 12k on clock? Cynical side to me thinks they know what the problem is but don’t want to fix it under my warranty… any help/ advice much appreciated folks! Thanks

MBF - You can get error codes which don't also throw warning lights.

So, you have bought a just over 3 year old Fabia with 12K miles on the clock from a dealer/trader a month ago and it is becoming troublesome - did it not can with some form of warranty that you can use, or at least it should be fit for purpose being as it is being troublesome a month after buying it.

 

Which engine and output power has it got in it?

[mark999]

The dealer is responsible for any faults within 6 months of purchase. You also have the right to reject the car. I suggest getting advice from trading standards or through any legal cover eg home insurance etc.

Mark.

I still have 2months on my warranty but the trader says they can’t do anything as there are no warning lights on now (they cleared them), I have spoken to the manager today who is going to look into it. I know something has happened and I want someone to look at plugs / coil anything else that might have caused this (from info gathered on this site), they just seem very reluctant to do anything. It’s a 1.0L engine, I’m not sure of the power. I don’t know if this is a common thing (bought it on a whim really as was looking for a vw polo (had 2 in the past), but this seemed to tick all the boxes. Thanks for any help!

The obvious question to ask you is was the car running normally after they looked at it for you and if so what is it that you are expecting from them?

 

I suggest having an independant VW specialist check it over for you including scanning for fault codes would be money well spent in giving you piece of mind and having something tangible to present them with as a warranty claim.

I’m looking for reassurance from them… I don’t think it is asking too much for them to check the spark plugs/coil, replace any if burnt out… my car is still in the 3 month warranty so I don’t want to spend the money myself as I think they should cover it… still waiting for a reply from the manager, and have sent another email…I will progress with head office tomorrow if I get no response, then citizens advice.

The first two are misfiring on cylinder 1. The last code shows there is multiple misfiring causing the ECU to shut down fuelling to the faulty cylinder in order to avoid damage to the catalytic converter and or DPF.

A quick check on line says "check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

 

My guess is that it is a failing coil pack. Get an independent check on the catalytic converter too as it is still under warranty.

I wonder; just how does a dodgy cat produce sulphur, in order to produce hydrogen sulphide?

[J.R.]

A bad diet, well its what happens to me so cats ought not to be any different

 

Topinambour is my biological weapon of choice.

@pikpilotWhen you could smell eggs from brand new petrol cars the Cat was certainly not due to be replaced.

To Ken and my fellow ebiker, the answer is the power of the internet.  I copied a comment from an ODB2 codes site https://www.obd-codes.com/p0301

Beware the American internet experts who look knowledgeable.

If the car is no longer misfiring then no coils are burned out, what do you think that the C.A.B. can do for you, reassurance?

 

To repeat what I suggested earlier:

At least that way you would have something tangible to ask them to replace or have the reassurance that you are seeking.

I shall, I shall. However, as I am not USian, I shall repeat. Where is the sulphur to make the hydrogen sulphide coming from? Not from the desulphinated fuel obtained from a UK filling station I think.
