Below is a recent problem experienced with my 2001 A3 T Sport, can anyone give provide any advise to where I stand? Any help would be appreciated. *Spark plug cross-threaded in cylinder 2, which has caused thread in the cylinder head to be stripped* On 28 April 2006 I was on my way to work when there was a bang and my car started to misfire badly. This happened at the roundabout near Crawley Audi. For convenience I decided to pull into Crawley Audi to get them to look at the problem. This is also the garage where the last service was carried out. The problem was diagnosed as a loose spark plug in cylinder 2 and I was charged £60 to fix it. Three weeks to the day on 19 May 2006 I was on my way to a meeting in Slough for work when I again heard a bang and the car started to misfire badly. This time I was on the M25 and was forced to pull onto the hard shoulder. I had no breakdown cover so had to call and join the AA. £160. The AA diagnosed the problem as a loose spark plug in cylinder 2 so it was exactly the same problem as before. This time however the spark plug could not be tightened as the thread had been stripped in cylinder 2. I therefore had to get my vehicle recovered and decided to take it back to Crawely Audi as they were the garage to last touch the car. Crawley Audi was extremely unhelpful and denied any wrongdoing what a surprise! They did however concede that spark plugs rarely come loose so the problem should have been investigated more thoroughly on 28th April. This would have prevented the £160 expense incurred by me to join the AA and have the vehicle recovered. At the very least I would have expected Crawley Audi to refund the £60 charged to supposedly fix the problem in the first place as clearly it wasnt fixed and as a gesture of good will take some money off the cost to rectify the problem. However, Crawley Audi refused to refund the money and their gesture of goodwill was allowing me to store my vehicle there until I decided what to do. What a joke! The bill to resolve the problem was £650 to remove the cylinder head and re helicoil cylinder 2. However, I fail to see why I should incur this cost as someones incompetence at an Audi main dealer has caused the problem in the first place. The car was purchased used from Aylesbury Audi in December 2004 with Full Audi Main Dealer Service History. Aylesbury Audi serviced car in November 2004, prior to my purchase. This is when the spark plugs were last changed. The car has been serviced and maintained by Crawley Audi since purchase. I do not feel I should have to foot the bill as the problem has been caused through no fault of my own. Somewhere along the line the spark plug has been crossed threaded in the cylinder head. This was either done when the car was manufactured, by Aylesbury Audi at the last service when the spark plugs were changed or by Crawley Audi when they tightened the loose spark plug in cylinder 2. Any idea where I stand compensation wise?
