There are several cars I know of now that seem to be having or have had issues with spark plugs, specifically NGK plugs. These are now standard fit on2.0TFSi engines (CDL code) on the S3/Leon Cupra/Cupra R.
My car with only a few thousand misifres and runs terribly and a lad on here with a Leon Cupra with a BWJ engine is using the same newer style plugs and he has reported problems too. Another lad I know has a CDL code 2010 S3 and it could not get past 60mph until the NGK's were swapped out for Bosch's.
I have new VAG Bosch plugs to go in mine, and I know that the other two cars run much better now with the Bosch plugs than the NGK plugs. On my last car, I never had any issues with plugs at all and would have skipped a thread like this, but as I understand it, there issues on Ed30's with plugs too.
Interested to have thoughts and experiences on this.
-
I had some NGK plugs go recently. Although they had been in for 14k miles.
The OEM ones seem to be better but i have replaced with new NGK ones. Will see how they get on. I have a set of Brand New OEM ones just incase :happy2:
-
When you say they went on you, what exactly do you mean?
-
I had really bad misfires (no fault codes logged though) when accelerating.
Changed the plugs and the issue was cured :happy2:
-
Interesting. Exactly as mine is doing although I am getting some logged misfires.
-
I had Bosch super's in mine and only lasted 8k. The NGK iridiums seem to last well in my car.
-
Al, do you know what model NGK plugs you have in?
I've just fitted a set of NGK BKR7EIX..
-
I had them out on Sat and never took notice. Will see them when they come out again though, but thats gonna be after the next trip unfortunately.
-

I only knew it was misfiring (apart from feeling it) by doing data logging and seeing them happen. The problem is they don't stay stored unless you get to about 25 on one cylinder in a short space of time. Then it logs a fault. I was getting between 10-12 on diff cylinders but the counter would go back to 0 after a bit if I took it easy. Would only do it when accelerating not idling.
-
My car is in the same boat. Only see temp misfires when logging but they are never stored.

Same here, spark plug changed cured it - though unfortunately charged the coil-packs first :rolleye:
-
does any1 have the part numbers for the oem 1s for an ed 30
-
NGK BKR7EIX
-
OEM Plugs for all 2.0 TFSi engines is - 101 905 631 H - Bosch Longlife Plugs :happy2:
-
It seems that you have issue with double platinum NGK plugs, but it worry me because I have just bought a set of NGK BKR8EIX. :scared:
JKM Tuning provide NGK BKR7EIX and BKR8EIX, so I guess it is fine.
Does any body had them fitted on their car and can give a feedback?
-

Carl, my ETKA seams to say 06H 905 611 Longlife plugs (AXX, BWA, BPY, BYD)...
-
They are Longlife plugs whereas the ones i listed are Bosch Longlife ones.
The Bosch are the latest plugs they sell ( i bought mine about 3 weeks ago )

Just to show i'm not going mental :smiley:

Oh, I believe you, Carl.
Guess my ETKA's not as up to date as I thought :ashamed:
I've just fitted the ones JKM sell and all seams fine for now..

I had to go and check incase i'd put the wrong no. on from the box :grin:
What update are you on??
Mine is
ETKA 7.2
VW - 843/417
Skoda - 377/417
Seat - 371/417
Audi - 843/417
The 417 is just the pricing so don't worry too much about that but the first no.s are the actual update revison :happy2:
-
ETKA 7.2
VW - 842
SEAT - 370
Skoda - 376
Audi - 842
Guess I need to update :happy2:
-
NGK BKR7IEX's seem to work well on the FSi and ive not seen any problems with them so far. May just be the standard NGK's that have been an issue. I have had more issues with Denso and Bosch's in the past.
-
My NGK that went were BKR7IEX's
-
Gapped or standard 0.80?
-
Standard as far as i'm aware. They were put in by Skoda on it's last service. Only lasted 14k Miles :fighting:

Hi guys I believe I may have spark plug issue's or coil packs aswell just took my Ed30 a wee blast with my mate to let him feel my coilovers car was running for a good 5/10mins warmed up left his street 30mph then headed out of town onto a 60mph car was running my pump giac map and as it hit over 2500rpm the car began to misfire and judder we both thought coil pack but no eng mangment light on, So exited the roundabout tried accelerating the missfire came back along with the Eng mang light flickering on and off?!?!
I drove the car home safely there but have noticed that while idle at the traffic lights its not running right at all! I had the car out last night and it was running fine :smiley: Its done 25,500miles and still on original plugs and coil packs, I'm just going out to check the coil packs :fighting:
-
Well mine seems to be getting worse. Massive amount of misfire this afternoon, with the engine management light flashing with it. Roll on the fitment of the new plugs.
My new plugs are 101 905 631H (Bosch).

Whilst i had not noticed any misfire or MIL issues prior to my plugs being changed today, i must say that the car definitely feels and idles better with the new plugs fitted :happy2:
First plug change in 44K, won't be leaving it that long again as even Mrs Beddie could feel the difference straightway!

Why have I just fitted NGK PFR7S8EG's then not BKR7EIX or BKR8EIX? Mines only a GTI rather than an ED30 but even the NGK website lists the ones I have as the correct one, not the other codes?

My mates going to price me these up tomorrow hopefully cure my missfire :driver:

Most "racing" spark plugs are just colder heat ranges of the same street versions spark plug. Their internal construction is no different than their standard heat range equivalents. Racing spark plugs do not make more power in an engine, rather, they allow the engine to make more power. Meaning, after all the engine modifications are done that add power, a racing plug is better designed to operate in the torturous conditions created by those modifications. If you used a regular plug in a modified race engine, it would quickly be destroyed, while a properly selected racing plug would endure the extreme limits of that motor. Take that same racing plug, however, put it in an unmodified motor, and it would foul out within minutes.
The differences between a racing plug and traditional plug are not solely heat range. There are firing tip configurations necessary for survival in alternate fuel racing and situations of extreme boost/compression (such as retracted-nose insulators or surface gap firing tips), which would run very poorly in an unmodified motor. However, there are some very effective race plug design features including ultra-fine wire electrodes, gold palladium, platinum, iridium electrodes and cut back ground electrodes that are now available in standard non-racing heat ranges, these can maximize fuel combustion and improve performance in unmodified motors as well.

:signLOL:
Why not just post the link Jason hahaha

I wonder if the NGK plugs being one stage colder is whats causing mine to run like poop. Still totally stock and misfiring like a barsteward all the time now.

Hi Guys ,
thought i would post my findings on plugs , well my car has eaten 3 sets in a year (2 standard sets and 1 off the lower heat ngk range), symptoms are missfires with no codes stored , accelerating in 6th around 3,000 rpm cause jerky driving and loss of power.
Went to see Ben at Revo (top bloke) and he thinks i have oil leaking somewhere (possibly from the camshaft bearing cage) which is getting into my coil packs which is killing my plugs.
there is oil residue in my spark plug holes , you can feel it if you put your finger in :laugh:
i have written to SEAT with his Bens comments and im waiting on a reply.
i know of another Cupra which has the same problem but more advanced than mine to the point its killing coil packs.

Looks like my mate seans car is now the same. He said he was having to change plugs every 3k and it was going through oil like mad. Said his plugs are oily. Compression testing tomorrow

is this the guy who has posted needing a new engine?

Yes. I dont think a everyday driven car has seen more abuse than his. Its had more WOTs than mine and waynes combined albeit with more mechanical sympathy. His car was knocking on 80k so I suppose he did alright out of it. Prior to this happening he said he was having misfire issues. Still went well though at WOT, when I last went on a run with him 3 weeks or so ago.

Carl - Do these look like the right OEM plugs - http://www.vwsonline.co.uk/car_parts_bristol/vw/golf/golf5/electrical/101-905-631h.html (http://www.vwsonline.co.uk/car_parts_bristol/vw/golf/golf5/electrical/101-905-631h.html)

I think they are mate its got the same p/n just below in the quick view bit 101905631H as in the picture posted in page 3, but i got mine for either £32 or £34 from David at Sere on SCN might be worth droping him an email :smiley:
