My 2-bits worth: if the K&N is an oiled filter your MAF has a film of oil on it now and needs cleaning. Cleaning the MAF is tricky. I was advised not to touch it if there were no problems faced, when I was thinking of cleaning it as my car had run 30K+ kms. A boost leak would be apparent right from 2K rpm but you have stated that the car pulls cleanly upto 4k rpm. If the service station proposes to clean the throttle body, make sure they have a new gasket in stock BEFORE they detach the throttle body. Otherwise your car will be taking some "time off" till they get a new gasket.

If the engine is not at all responding after 4K rpm i suggest the first thing you do is plonk in a new ECU and check. It could be some error in the ECU which makes it kick in the rev limiter much earlier that it actually should.
The ECU should be the first thing to check.

Plus your theory is flawed. Rev limiter is a digital setting. Not a dial that could have slid down to 4000 rpm.

Pls check your turbo plumbing. A leak in the same could lead to this situation. To be specific, the intake of the turbo needs to be checked.

to be honest when i started this thread i knew i'll be bombarded with couple of factors causing the problem i'm facing. And as expected some of the factors were really giving me goose bumps and some of them were a relief(yeah in a negative way).
Well i was slowly making up my mind...saving money, collecting more money. I just wanted to save more and more before taking the plunge to get rid of this problem. I was fearing an expense in excess of 20-25K or even more. I had already cut on my pleasure expenses. And MOST importantly i was fearing that skoda might 'instigate' me for one reason or the other
But now i can say that this all is history! The problem has been rectified.
Ok the first step i took was to reset the ECU by disconnecting the negative of the battery and then drove it for couple of kms. I cud now feel the engine reaching upto 5K rpm after some effort but still it was not upto the mark.
Now just yesterday i got my K&N typhoon intake air filter cleaned and oiled properly and the problem is completely gone now baby! Its back to its usual acceleration and brute force. And it redlines to glory everytime i try it!
My only concern is the smoothness of power delivery. Though the acceleration is typical of 1.8T engine but somehow its not as smooth or linear. I'm suspecting the throttle body as it might need cleaning as well. Any precautions should i take before getting the throttle body cleaned??
Total expense at the end was Rs.300. Now all the saved money will be pumped into partying. Special thanks to 'performance zone' who did a good job of cleaning my filter. Thanks Dikshit & Yatharth.
Thanks a lot for your responses guys.
