Finally received the oil filter in the post. Weeks late!
Took my car down for an oil change (I provided the oil and filter). Garage was busy, so they dropped me off back home, said would drop the car back later. They did not, so no car for the evening...
Eventually got it back next morning, and they waived the labour cost (only £15 + vat) due to the inconvenience. Nice one! Every little helps...
