Thanks to Stephen (Samuir1974 for running VCDS on the Fabia.

Logged two codes on the 4th of April when it was running like utter $hit!

P0106 - MAP/Barometric Pressure Circuit Range/Performance Problem

I had this fault code before when Skoda themselves found a loose vacuum hose. Turns out it seems that, that is the case again. Fault codes cleared & will run another scan in due course to double check.

Again, thanks to Stephen & also George above for where to look & advice.

Hope this helps other Fabia vRS owners too. Car is running sweet and putting a smile back on my face.

Karl.

No problem mate - HTH; anytime!

"why do Skoda put '98 Super (95)' on the filler cap lid of a 1.4 TSI / TFSI 132-136 kW Twincharger.?" I would guess because the recommended fuel is 98 RON but to confirm that it will run perfectly well on 95 to 98 RON?

 

"98-100 ron widely available on Mainland Europe" - my emphasis.

 

As I said earlier - the vRS is designed to run on fuel from 95 RON (widely available) up to 98 RON. Running it on 102 RON may do it no harm, running it on 97 RON (frequently available but not as frequently as 95 RON) certainly will not.

There are Members on here that have run these cars for over 5 years now.

There are many that know what works and what causes issues.

 

You have been in this section now since 2014 and never bought or run one of these cars,

you have researched and written a pinned thread, so do you think it is all an internet myth, and that the cars do not run better and more reliably on Super Unleaded, 97 or 99?

 

Do you still stand with VW know best, their first Spark Plugs were wrong, the 2nd must be right, and the 40,000 Service Change is right?

 

Do you just think, believe VW, they know best, they never have issues, and if they do they will quickly sort it out?

All EU Approved Petrol Cars are designed and have to be able to run on 95 Octane.

That does not stop manufacturers from having Recommended Octane Fuels.

Fuels that may lower Emissions and improve a vehicles performance, (or reduce the reduction in performance)

even daily drivers driven at UK NSL's

A VW GTI is only maybe from 190-210-220 ps 1.8TSI or 2.0 TSI and yet VW Recommend Super Unleaded.

A 1390cc 1.4 TSI Twincharger can be producing 190ps as standard and benefits from Super Unleaded as well.

(if you want to run 95 ron Unleaded, then thats what you do.)

Not rocket science, & not rocket fuel, just the recommended fuel by the manufacturers on the Filler Cap Flap 

of a Mk2 Fabia vRS Twincharger. *Super 98* (95)... 95 being the minimum and safe to use, obviously.

Needs to cost no more than £2.25 a tank fill more than 95 ron, and then drivers can decide if worth while over time.

ie Less issues with cold starts or any other issues.

For the cost difference you might even find it pays its way.

Why anybody still continues to give credence to this self professed authoritarian of the Fabia vRS is beyond me!

 

Just ask yourself who is in a better position to understand the petty foibles & idiosyncrasies of the of the vRS:

 

A) Someone who doesn't & never has owned one but merely read a few reviews.

or

Devoted owners (some for 5 or 6 years) who know that the car definitely runs sweeter, performs better & delivers better mpg when run on at least 97 & preferably 99 RON (Tesco Momentum is my preferred fuel).

 

I know who I would rather believe.

 

I know this is a public forum & all views are welcome, but personally I think it's time Mr VXH26 bowed out gracefully whilst he still has a little credibility left.

The Mk.II vRS uses a petrol internal combustion engine with a turbocharger and a supercharger, not some mystical improbability drive.

 

This engine was designed to use petrol with an octane rating of 95 to 98. Claims that using fuel conforming to this specification will result in damage to spark plugs would be more credible (i.e. believable) if they were backed up by evidence.

 

 

ps - Tesco have a presence in Spain now?

Did you read the OP? 

The person that posted this thread has a Spark Plug, a OEM Plug that is gone at under 10,000 miles when running 99 ron minimum petrol.

 

That is the Fundamental flaw of the 1.4 TSI / TFSI Twinchargers. The Intake design has 1 spark plug getting cooked,

it happened with the CAVE & still to a lesser degree with the CTHE, and with the engines use in the VW, SEAT & Audi running 

160ps plus.

That can happen on 95, 97 or 99 ron rather easily before the spark plugs get to 25,000 miles, let alone 40,000 miles.

I will be & have been changing my plugs at 10000 or less and will continue to do so due to how these engines behave.

No matter what anyone says I will continue to use 99RON fuel to try and help the life span and keep the engine running as clean as possible. It's there to be used & recommended. Simple really.

Er? Are we reading the same thread here? I don't think anybody is blaming the short life span of spark plugs on the fuel, be it 95 or 102RON, rather it is the shortcomings of the engine itself causing the problems.

It is an absolute undeniable fact that SOME of the engines seem to devour sparkplugs far quicker than they should, and USUALLY these are the same engines that use oil at a vociferous rate, doesn't require a great deal of brain power to deduce that the two are inextricably linked.

Regarding the octane rating of the fuel I use - When in Spain I run on CEPSA or REPSOL 98RON.

When in the UK I use TESCO MOMENTUM. Not at any time did I say I ran exclusively on Tesco Momentum, merely it was my fuel of choice, but in any case I never run on anything less than 98RON.

And no we are indeed fortunate NOT to have TESCOS' in Spain, but we do have the rather excellent Mercadona - far cheaper & much more local fresh products.

Just a quick update on this guys, I haven't been driving the car much since being insured on the works van.

It was quite intermittent with the rough running but still got on my nerves. I've been away too so haven't been driving the car much. When scanned it threw up a p0106 fault code via vcds.

Changed the MAP sensor yesterday and had my mechanic scoot round for any loose hoses.

Turns out the MAP sensor was at fault and the car now runs as it should. Quite shocking how a sensor can go after only 33000 miles but hey ho, it's fixed.

I'd just thought to update incase anyone else is suffering.

Thanks

Karl
