I've fallen at the first fence again; trying to unfasten the two retaining bolts of mass air flow sensor but they are apparently Fillister 5x20 bolts. A torx T20 doesn't match - Could anybody tell me the bit I need to fit these and where I could get one? Porsche say they can't help but only after they sold me the £400 part! Thanks for any help - Mark[/img]

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

The original screw has a Torx 20 (6 point) security head (the raised point in the middle makes it the security version. Yours has a Pentalobe (5 point) security, so the sensor screws must have been replaced at some stage. https://www.amazon.co.uk/Anytime-Tools-5-POINT-TAMPER-SECURITY/dp/B0026WMIV4 https://www.machinemart.co.uk/p/draper-14-7-piece-square-drive-48mm-long-tx-/
