The existing tool roll that came with the Porsche has some great tools but not everything I wanted to carry. I purchased a nice, little tool bag from Harbor Freight to hold additional tools, supplies and parts.
A nice guide from Petrolicious.
Your list may differ from mine but this is what I have:
Glove Box
- Flashlight
- DME Relay (Porsche)
- Fuses
- Multi-Tool (Gerber, Leatherman or similar)
Tool Roll/ Bag
- Adjustable Wrench
- Metric Allen Keys
- Utility Knife
- Screw Driver(s)
- Needle-Nose Pliers
- Channel Locks
- Wire Stripper
- Select sockets/ box wrenches
- Zip Ties (2×6)
- Steel Wire (10ft)
- Elec Wire (14ga, 2x4ft)
- Electrical Tape
- Multimeter
- Fix-a-flat
- Jumper Cables
Porsche Tools (in the OEM kit)
- Spark Plug Socket
- Tire Iron
- Screwdrivers
- Wrenches
- Pliers
- Allen Keys
- Alternator Belt

BMW Tools
The BMW had a jack and tire iron but no tool kit. So, I built one with the general tools and some similar to the Porsche kit. Some were placed under the rear seat and others in a box attached to the trunk wall.
