Took My Fabia 1.9 Tdi To Local Garage To Do A Mid Service Oil Change, The Sump Plug Just Kept Turning.they Refitted Plug, Said It Was Ok.noticed Oil Leak , They Drained Oil, Fitted Helicoil And New Sump Plug And Refilled Oil,said It Be Ok. Now I Notice It`s Still Leaking Oil. What Can They Do To Stop Oil Leaking From Sump Plug. I Want The Answer Before I Go Back To The Garage.

When they've tried and failed to Helicoil the sump, afraid the only certain solution is a new sump. If and only if they'll do it for free, they could try sealing with a little PTFE tape or preferably thread.
