Well spent the day changing the front and rear pads. Had to use vcds to wind back the rears, which was nerve racking as I'd heard you can fool the module if not done right, due to a software issue.
Disabling them I got a Handbrake malfunction error, but once I'd re-enable them, it was fine. Was scary at first though seeing that error.
Next up was to change the air filter and oil filter and oil. All went fine apart from one thing. As a precaution I'd bought a new sump plug and seal. So removed the old, drained the oil and put the new one back in, nipping it up tight enough.
Did what I needed to do and then rolled the car down the ramps and filled up with fresh oil. Didn't think anything of it. I then decided to give it a quick wash. Then when it was time to leave (I'd done all this on my parents driveway), there was a pool of oil on the floor. So back up on the ramps, engine cover off and low and behold, the new sump plug was leaking like mad. Tried nipping it up but it just wouldn't seal. In the end I had to put the old one back on. Difference between them is the washer, the old is a thin possibly aluminium one, the new is a thicker (about double thickness if not slightly more) and made of copper. It's the correct plus and washer (its just a washer), so no idea why it just wouldn't seal.
Other than that it was fine, I'm just baffled by the new oil plug.
