Just got diagnostic check on new 2015 Bentley purchase. What are the recommended choices to replace the two batteries in the 2015 Bentley Flying Spur? Are there any videos available to DIY? Thank you in advance.

I'm going to start with the batteries, but also have a laundry list of maintenance items to replace so any links to DIY would also be useful:

• Engine air filter
• Pollen filter
• Spark Plugs
• Brake fluid exchange
