Broken spring. I had 3 break between my 2010 & 2014 GSW. 2nd coil on all 3 broke off and made a "clunk" over bumps. My Q5 just started doing the same thing, have to jack it up this weekend and have a look.
Maybe for the island. Leave the safety of your little rock and up in the interior it has been $0.20-30/L more than RUG for the last 2yrs or more.
Last night all 3 or our stations here were $0.30/L more @ $1.999-2.039/L for D2.
