Yesterday I had my A/C bolt recall taken care of by my dealer. While waiting for my car there was another couple there also waiting. The "Service Advisor" came in and told the couple their car was ready but she then discussed how they had inspected their car's engine air cleaner and pollen air filter and they were both "dirty". She gave them a cost (for both over $120 or so) and gave them numerous reasons why they should replace both of these filters. The couple discussed it for a second and agreed to the change. This was an EXACT repeat of a similar conversation I witnessed a while back while having warranty work at the same dealership. This is also why I do my own minor maintenance. I can't see them taking the engine air filter out, inspecting it, re-installing it and going to the customer recommending a change. I also can't see them doing it with the pollen air filter. Don't know if this is a common practice at dealers but it apparently is at mine, which I try to stay away from! Just posting so you are aware of it and maybe you have a comment or two. FWIW.
