Change in design of TFSi engine. Important issue with fuel pump and engine wear

[Chris_Cupra]

yup, leon cupra

I've never heard of a Cupra/FR 2.0 TFSI engine with the new design in driving the fuel pump ...!!! Has anybody any information about that ...??? I think that in Europe, the only VAG car at present with the new 2.0 TSI engine is the VW Tiguan 2.0 TSI and the new A3 Sportback 2.0 TSI... Some Golfs V GTIs with the 2.0 TSI engine are in the US market...!!!

i'll post some pictures when I get back to Europe from USA (next week)...

Hi guys.
So, on which LCR's (year modell) is the new pump,or newer engine?
Is there a LCR with an engine without this problem or you should just replace the pump along with the other stuff when you make remap ?

 

[CupraSport]

I think it's only the Scirroco getting the new engine design at the minute

Already surfacing in the Golf from this model year, Leon is expected to be using it too. It's essentially the same engine, just a revised fuel pump system. Chain driven rather than driven directly off the cam. I doubt they'll announce it, as its to fix a design problem something few manufacturers are quick to admit to. They'll just start shipping them with the revision.

As I said previously, my car was a 2007 model and it was fine, but its a low miler. From most reports it's 05/06 engines that have had the problem more than others. But some newer cars have also been affected. As long as they are inspected periodically, there shouldn't be anything to worry about.

Doesn't affect the Mk1 Leon Cupra R, different engine and model type entirely.

Unless you mean the Mk2 Leon Cupra which isn't a LCR

Pretty much any Leon running a 2.0TFSI engine since 2005 can be affected. So that's Sports, FR's and now the Cupra. The Cupra does use a different variation of the engine though compared to the Sport and FR and therefore may not be as affected. The problems were first identified on 05/06 cars running this engine and that's across the brands VW/SEAT/Audi

However the Cupra shares the same basic design principal of driving the pump off the cam-shaft like earlier models so therefore is likely to be affected in the same way. The Cupra shares it's engine with the Golf ED30 and some elements of the Audi S3 also

at the end of the day its a metal part rubbing against another matal part. unless both parts are exactly the same hardness one is going to wear. and since its made by pedro on a budget and not the mclaren f1 team the odds are were all going to suffer from this to some degree.

 

[G!zmond0]

You got me. I meant the new cupra.
That is a major screw up.Your car doesn't have the problem because the mileage is low no doubt about that.
Damn, a sports car with problematic fuel feed.How worse can it get

Indeed, well they teflon coat the cam bucket, but that rubs off and then it wears through the metal eventually.

Can't really blame the spanish for this one, they get supplied the engines by Audi. Usually built in the companies purpose built plant in Hungary I believe.

Not at all the same engine! The chain driven 2.0TfSI is from the EA888 series/family. While the older 2.0T(&2.0FSI) are essentially bored out 1.8T's yet lacking the nice 20v head design... Oh & part of the EA113 series/family that were essentially reworked EA827's from the early 70's!

 

[G!zmond0]

It's just irritating.I mean this car costs almost 25 000 euros.OK i agree that Audi is the more expnisive variant and you have to pay more to get the better quality but engine problems .come on
A fuel pump does not cost extra 25 000 euros (audi s5 for example.)


P.S. PEDRO

I've been getting some starting issues to add to the list of blips of S3 ownership so I'm getting them to check it at the next service. I won't be keeping this car much longer. Can't make up my mind what I want next, but for the first time ever I'm starting to watch the running costs.

I'm sure the 'new' facelifted S3 / Sportback released last month have the newer fuel pump as the CO2 / MPG and BHP figures have altered slightly.

Our car was 221g/Km, but on the DLVA checklist the new S3 shows at 217g/Km.

Odd that, the TT-S with 272ps engine has a co2 of 190 something !

It's a fair bit lighter (100kgs or so), as its half aluminum floorpan and much smaller body area panels on the TT. The S3 is nearly 1600kgs.

s3=199g/km, s3 sportback=201g/km .

I wouldnt have thought weight would make any difference to how much co2 it puts out though, surely a more powerful version of the engine would kick out more co2 unless of course its fitted with a more restricitive cat.

No, the new S3-Sportback (the 5-door version of the S3 hatch, and slightly longer) has exactly the same engine design [belt driven camshafts, and intake camshaft-driven high pressure fuel pump, and no the newer Audi's Valiable valve lift (AVVL) system]. Essentially there is no revision for the K04-type turbo bearing 2.0 TFSI engines (S3/Cupra/Ed30) at the moment. There is a rumor, that these revisions will start in the after mid 2009 production models...

I have a leon fr 2 litre petrol turbo with no mods and 17000 miles on the clock, today whilst joining the motorway i did i admit give the car some welly accelerating in second and then third to the red line though not exceeding it when suddenly no power at all the car would not even rev i coasted to the hard shoulder tried starting the car but though the starter motor turned etc no firing up of the engine, i tried one last time and it rather lumpily started like it ran out of petrol and has run fine since.

Does this sound like the fuel pump/engine wear problem?? There were no engine management lights etc on after the incident so would it log a fault code if i had a dealer look at it?

CO2 is measured in g/km - so the heavier the car the more the engine has to work, meaning the CO2 levels are increased. The figure is worked out for each car, not each engine

oh ok, yeah that makes sense
