Does anyone out there know whether there is a known weakness of the coil pack fitted in the Polo 1.0e AUC engine, 1st registered Sept 2000. The car, belonging to my other son, has just experienced it's second fault of a misfire in 3 months. It has just been rectified by fitting another lead to plug number 3. The first fault was rectified by fitting a full set of leads. New plugs were fitted as well. Thankfully, we used genuine parts and this time it was replaced under warranty, but we still had to pay for the diagnostic and labour. Just wondering if it would be wise to get a new coil pack, we do not want this to happen every 3 months! Has there been any mods by VW that we are not aware of? The car has now done about 65,000 miles. It is still on the original pack. Do these 'wear out'?
