Hi guys, just about to change my engine oil, the screw (to release the engine oil) seems to be a special type of screw (flat head philips screw) within a special housing. Does anyone know how i can remove the screw without breaking anything? Thanks
 
Got it guys, it's a flat screwdriver, you need to push the screwdriver right you (on the face of it, it looks like a huge screwdriver is needed but you don't. Oh, also no need to remove any under tray. It as easy as jack up car and remove sump plug.

Plastic sump plug and plastic sump. Can't over tighten the sump plug as it has a locking tab and you can feel it click into place when fully tightened. Have to remove the under tray in a Polo 1.8 GTI!! Found an interesting solution - only need to remove 3 screws on the under tray and then use a short length of plastic gutter from the sump plug to the oil drain can over the under tray.:) Surprised at the amount of oil needed - 5.7l with filter!!
 
But why do they need changing? Are they a use once item, are they damaged/broken when being removed? Snapped or threads stripped?

They are meant to be a single use item, ie replaced rather than refitted. It's a "plastic" sump plug and a "plastic" (PA6 35% glass fibre reinforced) sump.

The design of the plug is meant to make it impossible (!) to over-torque when fitting and so damage the sump. The threads are coarse and there's an o-ring to help sealing, there's no need to torque the plug because the lug on it snaps into place to secure it. You can see it in this photo.

When people use a screwdriver to remove the old plug it often gets distorted, hence best to replace it, using the correct tool to remove it reduces the chances of damage, at the very least replace the o-ring.

Given the cost just fit a new plug... or use an extractor to drain the oil in which case the whole sump plug renewal question is irrelevant.:rolleyes:

Thanks for that, a clear concise description.
