    Try having to buy 8 of them! chances are if ones failed then the others aren't far behind. Also might be worth seeing when your spark plugs were last changed and put new ones in at the same time. I only use audi or tps as well

    GSF do a BERU 'Made in Germany' coil pack which they say is similar to OEM quality.

    They're approx £27 each, I've been running four of these in my car for 6 months with no issues after my cylinder 1 coil pack went. I've kept the old three for spares and always keep one in the boot just in case!

    Very easy to change, just need to be careful not to break the plug from the loom when removing it.

    i got one today from VW. £34.90.
    fitted it and my light too is still on. if it was a dodgy coil pack causing the emission light to come on, should it reset itself now, or will it need vagcom??

    You need to clear the fault code in vagcom and it will get rid of the check engine light
