I purchased a new A4 from an Audi dealer on 10/1/2005 for £23,000.
The car was brand new and came with a 3-year warranty. On 3/8/2007 I took a further warranty through the dealer for a further 3 years for £700. To keep to the terms of the warranty terms I was advised I would need to have it serviced at Audi dealerships. I have done 182,000 miles in my Audi and have always had every service and any work has always been done at the Audi dealer I bough it and the warranty from. It has been serviced at between every 15,000 and 20,000 miles whenever the service light came on. Any work that was needed was carried out straight away by the dealer apart from tyres.
I have actually spent £8,600 on servicing and remedial work. This works out at £1,700 a year, which is a lot of money. My Multitronic transmission has now failed and the warranty underwriter has now told me that my warranty is invalid as I have not followed the correct Audi recommended oil changes on my Multitronic transmission. I do not know a thing about cars, yet the Audi dealer says it was my responsibility to make sure the oil in my gearbox had been changed. My reply was if I was told to have it done I would have said do it straight away. I have been told by Trading Standards there are consumer laws about reasonable care and attention.
