Hi, I'm new here and have a very limited knowledge (if any) of maintenance so am entirely at a loss on what the heck is going on here and how to remedy it but here's the problem as acurately as I can describe it :-

The car is an Octavia vRS Y reg, I purchased it around 2 years ago and have had no real problems, anyway about 4-5 months ago a problem started that has gotten worse as time has gone on, it started off one morning when I went to pull off my drive, I started the engine and sat there for a short time and it was as if the car was very gently accelerating itself every other second, the revs guage was showing that this engine 'pulse' was going to just over 1000 revs and then back to almost zero, after a short while, maybe 45 seconds this seemed to fix itself.

Over the next few days this happened again once or twice but no other problems. The next symptom was a bit more worrying and still happens today, I can be driving along with no symptoms at all and then if I accelerate quickly passed another car or drive at a high speed this seems to trigger a reaction - when I then slow down to a stop or very low speed, as soon as I go to pull away again the car starts to judder and kangaroo and I have to get the revs right up to try to pull off , if I dont do this then the car doesn't stall but there just seems to be no reaction from de-pressing the accelerator at all, then all of a sudden, maybe after 5-10 seconds I get some reaction from the accelerator and I can move again.

I have had the problem looked at and the guy plugged a small computer into my dash board and it showed 21 faults ???, the guy then attempted to fix this, he did find a few things wrong and sorted them out, 1 was a valve somewhere on or near or relating to the turbo and the 2nd was a greenish looking rubber band looking object that had split, when he replaced these items and cleared the 'orange light' engine fault indicator from the dashboard the car did seem to run better but that was about a month ago. Yesterday I was coming home and accelerated a little hard passed a line of traffic, I then reached an island and attempted to pull away and the car juddered and almost stopped after only moving about 3-4 yards much to my horror as a large artic was about to plough into the side of me, all the way home then if I tried to accelerate it was as if there was a 4-5 second delay before it reacted and the same symptom at islands and junctions.

Hope I've described enough for someone to know what I am talking about and sorry for the lack of technical jargon, can anyone help please ?

Would love to know answer to this. My vrs Oct 02 plate. Judders or idles rough now and then. I don't know the answer to this but few months ago a coilpack went. This symptom is similar but not as aggressive. Could it be another coilpack breakdown. Any answers would be great.

It would help if they gave you the codes they found, then you can look them up on the Ross Tech wiki.

The fact that the idle is hunting after a cold startup suggests there's either a problem with the secondary air injection system, or the coolant temperature gauge, both will cause the idle to fluctuate after a cold start if there's an issue with them. But with 21 fault codes it could be loads of things combining to cause the problem :S
