Hesitation Cupra 280

[MrJohn91]

Hi all,
I've just bought a Cupra 280, 14 plate with circa 35k miles on it. (Bought privately) I've noticed a good second hesitation at 2.5k revs, this is very noticeable in the lower gears.
The only fault OBDeleven is showing is a Haldex clutch pump, intermittent. Could this be the cause? And as a complete novice is this something to get sorted in a hurry?

What's the service history? Has air filter been replaced? Seats official line is change every 40k. A forum member had a similar issue with hesitation and still running original filter. Filter was changed and hesitation was cured.

I'd be amazed if that was correct as that code relates to 4wd system !

Haldex is the system VAG use on AWD models like Golf R and S3

 

[JohnWB87]

There is a chance that the Cupra's diff would show up as Haldex. I remember reading somewhere that it is essentially a left to right implementation rather than front to back.

I'm under the same impression... Cupra front diff is haldex system.

 

[MrJohn91]

Interestingly it's had a full dealer service history but looks like te fuel filter has never been done. Not sure if this is standard these days? Also in the service book there is an "additional tasks" for HALDEX clutch and this has never been done either.

From memory the Haldex needs an oil change at 20k and Filter / Oil change at 40k I am sure there was a thread on here but could not find it. The only stuff I could find on the fault code was on the Skoda in Russia and Germany and both said it was dirt in the filter. I would have a chat with your local garage and see if they can help out.

So is there is a possibility these 2 could be linked? My hesitation and this warning?

I would check with Garage, as I say its just memory that said 20k it may have been longer but best to pop in to a good garage they should be able to help.

While speaking with Will at VRS, he mentioned that the Cupra engine changes cam profile around that point and that can also appear as a hesitation.

I can verify the truth in this. It is more noticeable if you accelerate on part throttle rather than foot to the floor.

From what I've read about it's implementation on the golf gti PP it can be considered a "haldex" system as it is an electro-hydraulic activated clutch system that operates on a single output shaft.

But the code listed above relates to the pump for rear haldex clutches as used on AWD models. This particular code will be familiar to any early mk6 Golf R owner as pre may 2010 models had a faulty batch of that particular pump and lots were done under warranty.

From a purely engineering point of view I'd be surprised if VAG used the same code to relate to a front VAQ system

But back to hesitation issue. Even if it was VAQ related surely that would have a symptom more akin to clutch slip or Traction control issues rather than a flat spot in power delivery

Are you running any induction modifications and what fuel are you using on a regular basis?

No modifications at all and I was told previous owner always ran it on BP Ultimate or Shell V-Power and I always use the latter. It is very much like a flat spot. You can feel it up to and including 4th gear.

I've been thinking about this and having had an early 64 plate 280 previously I have a recollection of thinking similar in the early days. I also have a memory of a thread on here with others discussing it.

It could well be the map on the early 280s. I put it down to the boost not building quite how the ECU expected.

Thinking about it more whilst writing this it tallies with what I've read recently about why some of the turbos were failing in 14/64 plate cars with this engine. That was apparently to do with the impeller catching the housing. Perhaps whilst not all failed it added a bit more lag than designed for???

I certainly always found the boost came in very abruptly at around 3k and it is smoother now in the 300.

Could it be possible that this is simply the boost kicking in and I'm just not used to it? Embarrassing much if so!!

I have the same issue, my 280 seems to stutter a little at 2.5k rpm when lightly using the throttle. I've heard that many Cupras do this, also had the dealer check it out and they said it was all good so I have learned to live with it...

Yeah I would say it's more noticeable when driving lightly. This does make me feel a little more at ease for sure.

I had issues which turned out to be the variable lift system playing up!

Don't like reviving an old thread; But this has been very interesting.

I've forked out for a few diagnostics at my local indy and a seat specialist thinking i genuinely had a misfire or something along them lines because i was experiencing the same hesitation, even had some live data done which obviously shew no misfire count on a road test despite getting the hesitations.... at the same RPM as what a few folk have stated in here. - Truth be told it could actually just be a characteristic of the Cupra 280?

I wish i had found this prior to my worries lol..

I must admit I changed this in obd11 and while the hesitation is still there, it doesn't slap you quite so much.
