Let me put this straight. I have no complaint about the service I have recieved. I am however very surprised that, given the state of my filter, that it is not on the 'replace' list on a 20thou service. I would have been driving with this airfilter for another 8thou miles if I have not checked it personally. As the title states, check your air filter. You check your oil, water and other fluids. Given, in my opinion, that most folk who buy these cars tend to look after them, I thought id point out a possible flaw in the servicing schedule.
