Flat spot at 5200rpm on 2.0T - Does yours do it?

[cuprak1]

I have this on my car too and i have always thought (and been told by revo) its the ecu holding back,,, i was advised to get the fuel pump but even people with the fuel pump are having the same issue.

you can actually see the flat spot here on my graph

Seems a common issue with a few of us over on SCN with Revo. There was a misfire issue bulletin from Revo on 08 engine I'll try and find it.

This is NOT a software issue;

this will be related to the TSB VAG currently have out on the valve springs in K04 cars..... depending on how old the vehicle is and how restrictive your exhaust is will depend on if the issue is apparent on the vehicle, our K1 has no such issue, none of the cars i have setup have had this issue unless they are within the said VAG TSB.

sorry to be blunt but i want it to be clear for you all so you are all well informed! 

[CarrG]

Yep sorry i didn't mean it was Revo specific. Just the bulletin came from Revo.

Carl are you able to post more details from the TSB - specifically the build dates of the cars effected? I'm looking at K04 cars at the moment, so would like to be aware of any potential issues.

I just copied and pasted this from a TT forum, maybe it is related

sorry for caps i just copied and pasted...

"REMOVE VALVE COVER AND THE COLOR OF THE VALVE SPRINGS IS WHITE & YELLOW. REQUIRE REPLACEMENT.

FOLLOWED ELSA PROCEDURE TO REMOVE HIGH PRESSURE PUMP. CYLINDER HEAD COVER. TIMING BELT. CAMSHAFT ADJUSTER. CAMSHAFT GUIDE PLATE. CAMSHAFTS. R&R VALVE SPRINGS AND VALVE KEEPERS. FOLLOWED ELSA TO REMOVE VACUUM PUMP AND CAMSHAFT ADJUSTER.

REMOUNTED ALL REMOVED PARTS IN RESPECT TO ELSA INSTRUCTIONS AS IN TIMING BELT. CAMSHAFTS. CAMSHAFT ADJUSTER. GUIDE PLATE FOR CMASHAFTS. CYLINDER HEAD COVER.HIGH PRESSURE PUMP. REFILLED COOLANT SYSTEM. CLEARED ALL FAULTS. TEST DROVE VEHICLE. RE SCANNED AND NO MISFIRE FAULTS PRESENT."

So, if your valve springs are White and Yellow, they are the wrong ones, apparently.

So its the valve springs then, and if I get them changed the flat spot should go away? How comes you guys havent made this aware to your dealers? Also I emailed you guys about the flat spot and there was no mention of it possibly being related to the valves

Good option to go and get supertech valvetrain fitted then

Im starting to think maybe im better off getting rid. Absolute love how the cupra looks and all the stares it gets, but the 2.0TFSI is just too tempermental a engine for me. Plus stage 2 plus isnt quick enough for me either, so perhaps its time for me to think about stop throwing good money after bad and just get a evo x and throw money at that instead.

[robdf2]

Am thinking exactly the same thing.
but not an evo

....A friend recently bought an Evo X SST on 14,000 miles for £22k. I've driven it and it's a superb car but only when you drive it very hard. Even then it badly needs a louder exhaust and lowering. When just cruising you've got time to take in the interior - It's comfortable but terribly ordinary and feels like a very average family saloon car.

It'll cost you serious money to mod it into something really tasty imo.

The 2.0T FSI when tuned right is an absolute animal..

Tuning an EVO is no easier (apart from fueling) there are just more parts readily available and its more developed as a tuned engine making it appear that way..

To get either engine to 500hp would be very similar in costs

[Pummy]

Given your experiences and coming out the other end with some decent cars, would it not be more prudent to leave it for a year and see how this latest TSB turns out?

What have you got in mind? I have a few candidates, e92 m3, evo x, tt-rs. Or option 2 being keep the cupra as it is, and get another car like evo 8 and strip it and tune that, or a vauxhall vx220 or lotus exige. But will see once im 21.

Well the cupra only gets driven one way, I have no real need for a car. Also all the critiscism of the evo can be laid on the cupra also.

Both need lot of money to mod into something tasty.

Thing is though the evo has a better chassis and drivetrain. Im a VAG boy down to my socks, but they are just too tempermental.

Cant say I have ever had issues.. But guess I may have just been lucky..

I would argue the chassis side.. The Supercopa Cup cars are proof that when fitted with proper dampers its an absolute peach and for the drivetrain the Evo's blow transfer cases like there going out of fashion once there running decent power
