Flashing engine warning light

[Fleejay]

I had my 52 reg 1.4 Sport MkIV Ibiza fully serviced and MOTed about two weeks ago and I started her up today to find the engine warning light flashing and the ride lumpy and with generally lower power.

I was told that they replaced all 4 spark plugs during the service and I understand that this can cause the coil pack to go?

Does that sound about right? I can get hold of a VAG COM system - will that be able to tell me if it is the problem?

If it is, how much should I be paying to get a new coil pack fitted?

Thanks in advance!

EDIT: It's done 111k miles by the way.

If its a coil pack the vag com will say mis fire on cylinder 1 or which ever number it is. I pay about £23 for a coil and fit it myself as it only takes 2 mins. unless your with the AA then they come out and fit a new one and chatrge about £50

Thanks for your help Rich, I've got the VAG COM on it now, the codes are:

16684 - Random/Multiple Cylinder Misfire Detected
16686 - Cylinder 2: Misfire Detected
16688 - Cylinder 4: Misfire Detected

I've reset them all, I'll go for a drive around the block and see again what comes up...

EDIT:
16688 - Cylinder 4 Misfire Detected

has come back up again.

One more question: is it safe to drive like this? Or am I going to be damaging the engine?
