So a bit silly, I hoofed it out of a junction in sport mode pretty much from cold earlier and the EPC light came on and stayed on and the engine felt and sounded absolutely awful, like a constant misfire, juddery and down on power. I also thought I smelt a few oily/burning sorts of smells. Had to carry on a for several miles but stopped asap and turned the engine off. After 5 minutes or so I restarted and it seemed absolutely fine, no warning light and performance back to normal. 

 

Did I just trigger a limp mode by being a bit of an idiot, or could I have harmed the engine? Surely hard throttle in sport must be designed into the running tolerances, even from as good as cold? This was on V-Power by the way

Any comments on this folks?

check your plugs as a start and get dealer to scan for any errors

 

had any oil issues? have you checked oil recently?

How many miles done?

 

A Scan might not even show the Misfires.

No Fault Codes.

 

Spark Plugs most probably,

needs a new set,  2nd plug from the left as you look, drivers side.

 

Do not risk keep booting it unless they are checked.

This is on about 22k miles, it's a March 2012 registered car. Oil level was fine last weekend. Sounds like I may have the spark plug issue then? Will get it in the dealers asap.

Probably blew out a spark - if there was a code stored I'd guess at "multiple misfires on cylinder x".  Could be plugs past their best although if you take it to the dealer, you'll probably get a "if it does it again, let us know" answer.

as others have said, first thing i'd do is check the plugs.

Well apparently there is a known issue with the EPC light coming on under hard 6k+ revs acceleration which causes irregular running, which as long as it resolves itself after restarting the car, dealers won't be interested in. If this is the case, why on earth program Sport mode to pretty much redline??

Who told you that gem?

Funnily Dealers are not interested in much and then wonder why there are engine failures, common on Twinchargers

probably due to those Dealers that repeat constantly the same sh!te.

 

The known problem is caused by a spark plug arking.  it is a misfire,

you need to inspect the plugs.

 

So do we know what your plugs look like yet ???

, not just the tip, soot or oiling,  the ceramics closely inspected.

 

That EPC light coming on under hard 6+ revs acceleration is more liable where there is 95 ron Unleaded being used,

Did they ask you what fuel you use?

 

Recommended 98 Ron, or better and Good Spark Plugs,

& early cars having had an ECU update if not already done.

A Skoda main dealer from a technical bulletin. Car has almost exclusively only ever run on V-Power, they didn't ask this though. 

 

What sort of tool is needed to remove the coil pack? I would try this myself but I really don't want to work on this car for fear of messing things up, I'm happy to try and tinker on a 20 year old MX5 but not a 1 year old car with loads of modern tech!

The correct tool, or one 'Like i Made Earlier'.

 

If removing the 4 Coils and 4 Plugs i would be Fitting new plugs and not putting the old ones back in.

 

Easy to mess things up, so take care, & i seriously suggest you get the Spark Plugs changed.

£60-£80 well spent, maybe at a VW Independent , not a Skoda Dealership. They are too greedy. IMO

 

These plugs are over £60 to buy, but the VW Standard ones are under £40.

I might just take it easy, which i nearly always do anyway, and request plugs to be changed next service, which is due in a couple of thousand miles, so early next year.

Your choice, but if that was the first you booted the car and the EPC light showed and that is after over 22,000 miles, 

i would not be putting off, 

or just not booting the car until you do know how the plugs are.

 

If your MPG is getting worse, that might be an indication of a plug on its way out.

 

?? Have you ever been aware in the previous 22,000 miles of misfires or EPC light showing with hard acceleration over 6000 rpm?

It's not the first time I've thrashed the car, but the first time I stupidly did it from near cold. A spark plug issue would raise its head at warm/hot too surely? Yes, ideally I'll get the plugs out and check them.

 

Fuel economy seems to have very slightly dropped recently according to my fuellog app, but that may just be the colder weather etc.

Edited 7 December, 201312 yr by TeebsVRS

?? How cold have you been having it wher you are,?

it is -1*oC here now, 12.30 pm,

 and an ickle snow on the Ground.  Great Temperature for good MPG with a Twincharger.

 

Colder weather has a Twincharger running better, more efficiently, nice fresh cool air feeding the engine.

(Just like why people fit a bigger intercooler and different air intakes.)

unless you count sitting warming up and de-frosting,

& accepting on short journeys that it takes longer to get the oil warm. Then you might burn more fuel.

 

My mpg average improved by 5 mpg after the winter spec Tesco Momentum was available from the 15th October and 

the temp dropped to nearer 6*0C and below almost every day and night.

And that was driving the same routes and much the same speed unless really cold roads.

My car had new spark plugs recently and yet was still limping around. Just now I have a permanent epc light and serious limping. Booked in to get diagnosed...

@MRA13

See your other thread.

Do not pay them an hours diagnosis if it needs a new water pump, belts and coolants. (seals).

If they are getting the job to do no need to fleece you for £60-£100 over and above. They have done well out of you already.

Next diagnosis time with main dealer is free after my complaint to skoda UK. I am going to get an independent check too locally as the private dealer I bought from also provides a warranty. I will pursue a claim for the spark plug expense separately with skoda UK and the dealer given my car was no better, worse off as I drove home.

 

Can you just confirm, how many miles has your car done and when was it built.

The Water Pump does need doing on some from about 5 years old.

Symptoms can be a slight coolant loss, not always though, then the Exhaust Emissions light on or the EPC light, or both at once.

Sometimes in Cruise Control the lights might come on and the car go into Limp Mode.

 

It is just how they are and any dealership that deals with Twinchargers should be aware. Not as though an unknown issue. 

Charges for the Water Pump getting replaced varies around Dealerships.

Be sure the 2 belts are being replaced.

2 Year Warranty on parts and labour if you pay towards it, or a Warranty does, not if an Original Manufacturers warranty though. But yours is not the Manufacturers Warranty.

It's done around 32400 miles now. May 2011 build I think, Sept 2011 registered new.

I have skoda extended warranty from tomorrow. Private dealer warranty for 2 more months.

Thanks for the tips and advice.

Who told you this?

 

 

Sounds like you've blew a spark plug/coil by hammering it when cold, Saying that though if there no permanent EML light you may have got off lucky. The coils are pretty easy to remove if you have any form of tool box....I usually use a flathead screwdriver and some grips.

What plugs did you fit?

 

Standard plugs from dealer. My car is in at a specialist now who is taking a look at it today. His first impression is more likely to be ignition coils etc. Let's see. Cheers.

@MRA13

Did you ask the technician about the possibility of the issue being the water pump / supercharger magnetic clutch?

Hi, I mentioned the water pump as a possibility and other comments from the forum. I forgot to mention the supercharger magnetic clutch. He thought the water pump would be unlikely. I said I run it on v-power and use redex injector cleaner. He said to stay away from injector cleaner.

I’ve only had mine a couple of years and there’s been countless story’s of dealers fitting the wrong plugs, In that short time I’ve owned mine I’ve learned never  to trust skoda  dealerships with these cars.

 

IMO the best  performing plug for  standard mk2 VRS have been proven to be NGK BKR7EIX.
