My Q5 just died in Seattle traffic and I need it back by Monday for my commute. I saw videos about a $100 special locking ring tool but some guy said a screwdriver and hammer works fine. I'm scared of cracking the tank seal though. What is actually the best way to do this fast without the tool?
> I saw videos about a $100 special locking ring tool but some guy said a screwdriver and hammer works fine. ^ This. Also, you really dont need to drop a hundred bucks on that specialized Audi tool to get the job done. I remember being super stressed about my Q5 back in the day, thinking I was gonna crack the tank or ruin the seal. Honestly, I'm happy I didn't go the screwdriver route tho... those plastic rings are way too brittle for impact force and slip easily. I ended up using the Performance Tool W83001 Adjustable Fuel Pump Tank Wrench which only cost me about $20. It works well because it adjusts to fit the exact diameter of the ring and allows you to apply constant, even torque with a standard breaker bar. When I used it, the ring popped off without any drama or that scary cracking noise. No complaints about the tool at all for a budget option. Some technical tips since you're in a rush:
You might want to consider a Mayhew Pro 61350 3/4-Inch Brass Drift to distribute force. Be careful tho, those plastic rings are prone to cracking if you dont apply even pressure.
