Makes no difference if the light is on or off, scan it for codes or else you could spends ages trying to fix it.

Codes dont always help! My Passat 1.8t is playing up big time and no codes showing!

Juddering is usually coil packs or ignition amplifier.

Scan it - if no codes come back then I would look at replacing coil packs or ignition amplifier. My V5 used to judder like mad under accel and didn't bring a code back. It wasn't until I changed the ignition amplifer that it solved the problem.

ignition amp would cause it to run on 3 most of the time...even of idle...same with a coil pack from experience.

Could be a really weak fuel pump.

Whats it do it you have it in 4th/5th gear and floor it from about 2000rpm?  Stutter then?

Not from my experience. It would judder under load then clear under cruise conditions.
