I was under the (mistaken ?)impression that the 105bhp version did it as well.Also as the VAG 2.0 TDI 140 is basically the same engine,does it suffer too ?.If there is fix for one it should work on the others too whilst remaining Euro 1V compliant.I'm sure there must be a rather more elegant engineering solution than drilling holes in EGR gaskets. Perhaps some ECU work in controling the timing of the EGR valve in combination with the 14.5mm gasket would have been the fix VAG should have pursued,but i'm not an engineer. It just all feels very crude,like something i would have done to my mini in the seventies.

As I mentioned earlier it all boils down to emmision regulations,The reason for recircing the exhaust gas is that it keeps the Nitrogen oxide content low in the combustion gases,It also helps to regulate combustion temperatures and thus the regulation of the catalytiic converter.

Its all very well fitting reduced sized gaskets i.e below the req'd size of 14.5 mm but it will eventualy lead to the egr pipe and related components becoming prematurley blocked resulting in low flow of the egr and thus the engine management light coming on.

Just a little technical background for you guys !

I think your theory is a little over exagerated. If the waste gasses don't pass through the EGR and back into the engine they will go to the exhaust. If you read the service bulletin it states that the best happy medium is 14.5mm, that's not the original design intent.

We all know that EGR's clog up regardless of what size the gasket is that is fitted.

The one fitted to the ASZ engine is 547 A which is a different size yet again.

Aside:

Is it possible (easy) to remove and clean the EGR valve and put it back on?

Where is it? What does it look like?

Bit like the DPF on the Superb which clogs up & stops the car, progress is such a wonderful thing.

Ive heard Merc are scaling back Diesel research as they believe it might not be the fuel of the future due to the emissions problems, California I believe are trying to ban diesels altogether

Is there a direct relationship between EGR flow/mass and the management light coming on ?.I was under the impression that as long as the ECU thought the EGR valve was operating normally it wouldn't trigger the management light even if there was little or no actual EGR gasflow, as would be the case if the transfer pipe was almost or completely blocked. Looking at the rather slim transfer pipe fitted to my 04 fabia,i would be surprized if it wasn't substantially restricted after 3yrs and 40k miles. I stripped a Merc 6cyl diesel a while back and was astounded at the amount of EGR gunk in the inlet manifold,must have been 80% blocked. Is the actual amout of EGR measured in any way upstream or downstream of combustion?. Must be getting lazy in my old age,really ought to pop the bonnet and have a look myself. Think the furby is the first car i've owned where the sum total of the maintainance i've done myself is check oil and coolant, hasn't needed anything else.

Not exactly sure how the management system measures the flow but I know that on the 1400 16V petrol engines it can work out insufficient and excess egr flow rates and you wouldnt beleive how horribly clogged they become,some to the point of complete blockage.

I will research further into the BLT egr system and post my findings in due course.

Aside:

Its on the front of the inlet manifold has a shiny silver round capsule on top of it and a vacuum pipe,early ASZ engines have a vac operated flap,whereas the later BLT has motorised unit on the side of it.

As for ease of removal and cleaning out etc really depents on how competent you are ?,can be a bit fiddly getting to the base of the unit to remove/refit the egr pipe bolts.

Wouldnt reccomend removing the later one however as Im not sure if unplugging the motorised unit would cause complications and require adaptation ?

I suppose the question i really wanted answering was - Is the management light is triggered on the Euro 1V car if the EGR gasket is replaced with the earlier 9mm gasket from the Euro 111 car to cure the stutter . I've seen a couple of conflicting posts on this - some say don't do it, the management light will come on.Others have actually done the job with apparently no ill effects.

I would have thought any measurement of actual EGR flow would have to be taken upstream of combustion but will be quite tricky to interpret, as the flow will be changing constantly as commanded by the EGR valve.Condition of the pipework will also play its part.If low EGR mass triggers the management light,you would expect to see a rash of people with glowing management lights as the mileage built up and the system gradually became restricted with exhaust gunge,not a problem i remember hearing about.That made me doubt that EGR mass was measured,but i have been known to be wrong ......

500 miles later and the engine management light came on for a full day! 200 miles in that day. Left her overnight and started up today, 200 miles and no engine management light.

My Euro 4 compliant Skoda is now probably at a lower resale value than an 05 VRS. Anyone care to swap?

Facts = Remapped VRS so EGR probably turned down, and the engine management light thing didn`t show up till later. Apologies if everybody has rushed to buy a gasket, but i thought this would fix the problem. On a side note car does NOT stutter,

I give in!

PS. Nice to see posts from Techies.

By the way, is there a stutter on the 'new' Seat Ibiza?

Yes.

the rest of VAG do no have the 130 spec TDI since Euro IV emmissions regulations, all the 1.9 TDI's are now 105bhp

There are still Ibiza's being sold with the 130bhp motor and they have the same issue except they have a dealer approved (warranty compliant) remap that gets rid of it. The 100bhp engined Skodas, Seats and VWs also stutter and it's not hard to find people complaining.

I don't mind that it does it, I do mind their negative attitude to getting it fixed. They wonder why the fabia dropped from top 5 to top 30 in the recent satisfaction survey? Because the cars aren't as good as they were, that's why. The dealers are forgetting who they're there to support in their steel and glass edifices and SUK really do need to remember who pays their wages. They had a diabolical reputation before and they worked hard to get it back. But you can blow a lot of good will in a very short time by acting the way SUK are acting currently. And now they have decided that they will restrict the supply of spare parts? Mental.

As for driving round about the problem I refuse to rev the nuts off a diesel in every speed limited situation

To avoid the stutter I need 2nd in a 30 zone, 3rd in a 40 or 50 zone and 4th in a 60mph zone. Maybe you like to go work at Skoda with your head buzzing, but I want to be able to hear the radio thanks very much. And if you drive the car the way you suggest you cannot get anywhere near the fuel economy figures that Euro III car was capable of.

You can absolutely bet that every car survey that comes out, I'm giving them bottom marks as often as I can. And I would strongly suggest everyone else does the same.

perhaps the stutter 130 tdi is the reason why the fabia MK2 dosnt have a hot diesel VRS version. they dont want the new model to be a flop

So can the Seat Flash update be applied to the Fabia ?,I wouldnt object to paying a small sum if it erradicated the problem.

:confused:

Am I right in assuming that new build 2007 Bacon, Lettuce & tomato engine is getting the revised so called "fix" gasket replacement at the factory? or are they still waiting for people to report a fault and have it done at the dealers?

I have just recieved my special edition vrs, and having covered only 97 miles i am getting this stuttering in the lower gears, i will go back to the dealer to see if they can help?

Mmm.... would like to hear from anyone who has fitted the gasket to the standard Euro 1V car.Maybe your problem is a combination of gasket and remapped ECU.The fact that it didn't come on straight away suggests something is just outside limits for triggering the light.Fancy going back to the standard map or would it be too much of a wrench ?.

If you feel comfortable doing it, i would be tempted to drill the gasket out 1mm at a time i.e. refit it after every 1mm drilled and see if you can reach a point where the stutter is kept in check with no management light issues appearing.Could take a while,but might be worth it in the long run.

Just to deviate a bit,i picked up my Ltd Ed a couple of days ago - first time i've driven a Euro 1V car. Straight out of the dealers into quite heavy traffic and it ran like a dog - stutter/flatspot/hesitation.Almost turned round and went back for my 04 plate!!.Perseverance has paid off though,within a couple off miles it improved markedly and by the time i got home (about 70 miles) it was only just there , even when deliberately provoked.Not much mileage since,but feels ok when cold then throws a bit of a wobbler at around 70C coolant temp but improves as temp reaches normal.Strangely i can't escape the feeling that somehow this one feels more powerfull than my 04 even though it's still new and tight. I dismissed this as a figment of my imagination till today when i had a root around under the bonnet to see what had changed - lots of bits and bobs,but one thing hit me straight away, the trumpet and inlet pipe to the filter box are the larger Ibiza Cupra 160 items -much greater diameter than the ones on my 04.Did they run out of 130 spec engines and slot in the 160 from Seat !!!!!!

Just day dreaming - it does have the BLT engine code.

Let's know how you get on Mouse - don't give up,i think you're on the right track.

P.S. Did you drill the gasket at all or leave it with the 9mm hole ?

Right,

car flashed back to standard now. Gasket at 9mm. No engine management light for me as yet. Will be racking up some miles this week so will see how it goes.

Bought an EGR gasket yesterday and fitted it (part no 028 131 547B)

Skoda look like they have changed the part No and possibly the part itself. I would look back over the last couple of pages of posts before i fitted one though.Worth waiting a while till the dust settles over what will work and what won't.Don't want to cure one problem and give yourself another one.Three cheers for Mouse - he seems to be on point duty !!

So guys,is the 9mm holed gasket a worthwhile mission overall?

Please advise ta lots

Part No for the gasket is 028 131 547B and that comes with a 9mm hole in it,fitted one to my car on Saturday but modified it to 14.5mm as the bulletin instructs and my car is cured !

Well, 200 miles,later. With standard car. NO remap and 9mm gasket. All appears well. Will report back if Engine Management Light comes on. Over and Out!

Keeping fingers,toes and everything else crossed.Free cheese for life if this works !!

Its not tricky to confuse me !!! Do I go for the 9mm or 14.5mm?

The race is on for the best updates !!!!

Over to you guys, ta lots
