If you want to DIY it, you can do it for under $100. The only replacements are the oil/filter and the cabin filter. The cabin and air filter are at 30K, but I prefer changing the cabin filter more often since I have trouble with allergies. The rest are just checks and lubing the top. If you want instructions on the 15K items, you can click on my website link below.
If you want to do everything in the service (including reading the codes for the systems) you can order the
Durametric reader that attaches to a USB port. It reads the DME, alarm system, airbag modules and climate control codes for about $200.
