Octavia problems!!

:confused: First off I'd like to say hello to every one, this is the first thing I've written on Briskoda.

I am the owner of an 02 reg Octavia Vrs, and have had the car for about two months. In that time the Engine management light has come on 6 times!

This first two times I took the car to my local Skoda dealer as i was near by so thought it best to get things check asap. They told me there was nothing wrong with the car and that it was probably just a one off (twice)!!!!!

The third time I took it back to garage where I purchased the car, and in fairness to the gargae they have been very good about things. They dissmantled the exhaust re-sealed and re-built it and the car ran fine for a couple of days and then the light came back on again.

The fourth time I took it back again and the mass aire flow sensor was changed.

The fith time i took the car back they sent the car back to the main dealers who changed the oxygen sensor??

I picked the car up yesterday evening and this morning the warning light has come again.

Has any one heard of a problem like this before, and does anyone have any idea what could be causing this problem? I would really appreciate any advice, other than these problems the car is fantastic, not quite as quick as I'd hoped but still fast enough. The general build quality seam excellent and the space is very impressive.
