My Superb 1.8T is facing problem . It started with sudden loss of high end power and it is struggling from 3000RPM up to max of 4000 RPM . From 2500-3000 RPM onwards, I can feel some jerkiness in the engine. And the maximum rpm it can go is around 4000 RPM traveling at 150 km/hr. It seems like the car stuck at higher traveling speed from 120km/hr onwards. And the gear change takes long duration.

For slow driving at around 2000 rpm every thing is fine. There was no error codes or any signals appear.

I sent my car to Skoda workshop for VAG scanning and here is the result:

16684 po300 035

Possible ECU fault...a huge shot in the dark but it may be sending out the wrong error codes..this happened on our work car a while back. As it was faulty you could only do slower speeds as it had effectively "tripped" itself out

You are right. They just key in some code and reset the ECU. Everything is fine now. Thanks.

Wow what a guess...glad to be of help:thumbup:
