Hi, I am having a 2010 TSX, I got B123 service code too. When i went to the dealer he quoted me 900$
Replace air filters, replace dust and pollen filter with A/C frigi-fresh, Brake fluid exchange service (once every 3 yrs), fuel/air induction system clean-up service, power steering fluid exchange service.
Since i had tire rotation done in last week when i changed my tires and transmission fluid changed last year, they were ommitted this time.
But i am thinking 900$ is too high. Please suggest.
