Misfire.....

Featured Replies

I have a misfire. Just wondered if anyone else may have suffered the following;

Driving back along the M27 last night coming out of Portsmouth, the engine started running very rough, the emission control light started to flash and then the EPC light came on permanently. The car continued to run and i was able to drive it but there was no grunt available. Obviously the car had set itself into 'limp home' mode to protect itself.

Called Skoda Assist and a nice chap from the RAC was with me within about an hour, which for a Friday night was quite good. He spent an hour or so on the car, changing coil packs but the problem would not clear. Had all the plugs out as well just to check. The fault code kept coming up with a misfire on number 3, so in the end we switched both the plug and coil pack from number 3 with those from number 4, hoping that the fault would at least then move to number 4. Alas that didn't happen and the fault remained on number 3. At around about 23:00 last night he gave up, apologising for not having solved the issue and left instructions on what to do to arrange recovery to my local dealer.

This is where my vRS now sits awaiting further investigation by the dealer on Monday morning when they open again.

So the question is, has anyone else experienced this and if so what was the end result.

Many thanks, JT

thats odd.... so it wasn't the coil pack or the plug? a bit worrying :(

Damn right oh rider of sharks. It is a little worrying.

My car had similar issues, was told it could be faulty injectors, but turned out to be the spark plugs. All the best, hope for a good outcome

I would guess at a dodgy valve if the coil pack and plug are fine.

Thanks P1TT8ULL, bringer of doom and gloom. In all honesty though the RAC technician did suggest this after we couldn't rectify the fault in the number 4 cylinder using the same coil pack/plug combo. Hopefully it is not as serious as that but you never know. I will though keep everyone posted on the outcome :)

Sorry dude. It'll be covered under warranty any way. One problem these engines do have is the amount of carbon build up that occurs on the valves. One reason for water Meth.

Well the dealer found time to have a look today and initially it is not good news;

1. Oil in cylinder no 3

2. No compression in no 3

They now have to wait for SUK to allow them to proceed.

Ho hum, its the wait and see game now.

damn, lost compression = knackered :(

Thanks Sharkrider, yep knackered. Last time something like this happened to me it was just a busted push road in a renault 5. 30 minute job to sort once i had got a replacement part.

Anyway, spoken with the garage this afternoon and SUK have agreed for further diagnosis to be undertaken, so 'off with its head'. Only problem now is when the garage can start work as they are fully booked for the next couple of days. May have an update by the weekend.

Which car is this? I see you have a VRs and 1.2?

Sorry to hear your woes.

The one that goes through oil, as if we are not running out of it fast enough as it is. Or to put it another way the vRS :)

oh hell, something else for me to look out for with ares then

James, the best thing to do is dont fret about it. Beleive it or not some of these engines are really strong and dont use a drop of oil i.e. sharkrders, others consume it as if it is going out of fashion i.e. evil magyi to name but one. mine was marginal on oil consumption. Others have already had piston rings, breather pipes or short engines (the bottom end) replaced, but i am certain that there are many more out there which are fine. Just look at VRSy, P1TT8ULL and others who have tuned thers with no reported issues. Like most things in life, there will always be good ones and bad ones and unfortunately i have a dud. the worst thing or perhaps the best, it was only serviced on Friday shortly before all the real trouble started. Probably just a coincidence, but at least i have proof that everything was fine just a few hours before the misfire started.

My Scirocco (1.4 Twincharger) was suffering with misfires/loss of compression; VW changed injectors (there was a suspect batch for early 2010 engines which mine was) as it was burning plugs up at a stupid rate. They even changed the ECU for some strange reason. Real reason was wrong plugs fitted at service time (VW computer was programmed with wrong ones for a Scirocco), but it cost them a head rebuild, new piston and rings, set of injectors, coil packs (I think), 4 or 5 sets of plugs (wrong ones plus finally a set of new ones) and about 6 weeks of car hire.

As it was just serviced, then it points at something they did (wrong)...probably plugs as you don't get much grace if it starts to missfire with a heavily forced induction engine like the 1.4TSI...

Ok, I spoke to my dealer/service dept today (| called them) and apparently I have burnt a valve out. They are currently waiting for Skoda technical to tell them what to do next.

However, how do you burn a valve out? I thought this was a thing of the past.

It can happen on these cars along with carbon building up on them.CCan't see why they need to wait to be told what to do. Surely replacing the valve is the ovious answer unless something else is amiss.

I guess the wait is for Skoda UK to allow costs to be incurred and will have ti be done. However, I hope they will look into a probable cause, spark plugs in 1,2 and 4 a nice biscuity brown colour. That from number 3 was heavily sooted. I wonder if this is where all my oil has been going?

Sooty plugs are usually due to unburnt fuel. Which could have ment you had high carbon build up on the valve which stopped it fully closing etc.

Ok, as the dealer hasn't been keeping me informed, and I am working from home today, I thought I would pop round and see what the status was on my vRS. Well, to my surprise they are just completing the installation of a new engine. Apparently they had a Skoda tech in on Monday to see about another issue, saw the state of the head off of my engine, and told them to install a complete new unit. Hopefully i may even get it back tomorrow.

So new engine installed, new breather mod and hopefully it will not burn anymore oil. Well I will believe it when it happens but hopefully they are correct.

That's win! I've had misfire problems a few times in the time I've owned mine but haven't got any further than "Skoda UK don't know what's wrong with your car".

My misfire was fairly terminal in that the ECU sent the engine into limp home mode. On analysis zero compression on cylinder 3, and when the head was removed a portion of one of the outlet valves had gone.

Hope yours doesn't give you anymore trouble though. Others have had such issues which were related to spark plugs so maybe worth a look through some of the older threads.

Yeah I've been into limp mode too. There's a video I put on Youtube of my car sounding like a bag of spanners in a washing machine. One dealer did replace the spark plugs which helped, but a blip is still there.

At the moment I seem to be having problems with the DSG. Occasionally power cuts out completely under acceleration, followed by the overwhelming smell of burnt clutch. Also had severe stuttering at low speeds as well as a flashing DSG number on the display but no power. Told local dealer who simply said there were no faults logged and they could not reproduce the issue.

Best of luck with your new engine :)

Just as an update, I received a call from the dealer this morning which I was fully hoping to be, come and get your car, it's all fixed and ready to go. But no, more bad news. Having now put the car together again, it will not drive and that they (dealer and Skoda) are scratching their collective heads to work out why. So no returned car for me :(

OK, just heard back again and car now fixed following a software update. BUT after carrying out checks post the road test, one of the CV boots has a hole in it so they have to hang on to the car for the weekend and hopefully sort it on Monday provided a new one arrives. :(
