GTI feeling flat above 4000RPM

Because it feels really punchy low down and it tails off around 4-5k right to the redline. The car drives fine with no funny noises.

No guarantee I'm afraid! Maybe someone else could shed some light on it but if your dv is split which would be common if it's a few years old now then that's a typical symptom.
Scan it first and see what it says I suppose then throw the results on here for people to diagnose
TyGTI:
Mine is similar, has a dead spot around 4000rpm and picks up again at 5000rpm :stupid:
I have a gfb dv so shouldn't be that... I'd be interested to see if you can get to the bottom of this!

Just our of curiosity, is your car tuned or are you running on really slippery tyres? There's no way my stock GTI will spin the wheels in 2nd gear (it might of course do that with cold tyres and in cold and wet conditions) on tarmac. I do however have quality rubber in good condition under my GTI. I still feel like it would need a whole lot more power to _easily_ spin the wheels in 2nd.
If the DV is faulty, it should feel especially sluggish when the boost starts to build up and would hit the max at around 3k rpm.

My car is completely bog standard and the tyres on my car are cheap worn rubbish so I'm not surprised they spin up like they do especially in the wet!
I took the car out again last night and give it a good hard drive and to be honest I'm not sure if it's underperforming now. I think it might be partly due to the linear power delivery of the engine that is making me think the power is dying off at higher rpm when it probably isn't. I'm use to petrol engines which are quite peaky in that they deliver most of their power on the top end but I guess the GTI isn't like that?
I came from a remapped Audi A4 130TDi which obviously felt much quicker than it probably was due to the torque but the GTI doesn't feel that much quicker tbh...

A standard GTI is pretty much like that. The capped linear torque output makes the car feel a little underwhelming at the top end because the low end punch makes the car feel more powerful than it actually is. Nonetheless, the GTI's real life performance is awesome due to the large power band and the fact that it does still pull harder than a diesel at high revs. I really like the GTI engine the way it is - to me it feels like the power output starts "dying" after 5k rpm. Between 3k-5k revs it pulls alright regardless of which gear you're in. (And of course it sounds way nicer than a diesel, excluding idling haha.)
