2003 r53 93,000 miles throwing a P0455 evap leak code. Light comes on intermittently, gas cap has already been replaced. Wondering If I should throw down 130 ish on a new LDP and hope it solves the problem or take it in for a leak test....

 

Could try removing the wheel shroud and then checking the rubber hose connections from the tank to the gas cap.

 

Check the little black canister on the front of the engine and the connection to it.
