I am a newbie here.

My wife drives a 2009 X5 3.0i and has 26,000 miles on it. The other day, the dealer sent my wife an email recommending a fuel filter/system service and wheel alignment service on her vehicle. My wife called them and they said this is not covered under the BMW maintenance. I drove it yesterday for around 15 miles and I did not experience any problem as far as drivability is concerned. I would like to ask for your opinion if we should have it done. Thank you.
