Not on my motor, but one of my colleagues has a 2013 Audi Q5 2.0 diesel. Basically, he's just come and told me how much he's paid for an oil service comprising of fresh oil, an oil filter and a new sump plug. The labour charge of 1.3 hours was £159.00 which include the oil change and visual checks, and the total bill came to £389.00!!!!!!

So that means the oil, filter and plug cost £230.00!!! Now maybe I'm out of touch as to what is considered the norm for main dealer servicing and that engine probably has a big sump that takes 2 gallons worth of oil but fuck me £400 for an oil change just to have that all important stamp that some Audi fuckwit changed the oil for you. They also quoted him to change the pollen filter and quoted £60 just for the filter and labour was additional! Couldn't believe it.
Dread to think what brakes and other service parts might've cost!
