Just had my 80k service carried out yesterday by my local dealer (Edinburgh Audi) including getting the belts changed along with the waterpump. Also got a new radiator under warranty as the old one was leaking slightly. Was going through the bill this morning and noticed that they have charged me for 7 litres of engine oil - strange as I thought the engine only takes 6 litres. Also printed on the invoice was "tyre pressures set to 30 psi" a little odd as they are supposed to be 36 psi. I phoned the dealer to ask why they did this and was told that the engine takes 7 litres I argued that the handbook, previous service invoices and other dealers all say 6 litres - they refused to believe me and told me it is definately 7 litres. I then asked why they only put 6 litres in during the last service and he couldn't answer me, just said that the engine takes 7 litres. I then asked why they dropped the tyre pressures to 30 psi and was told because thats what they are supposed to be. I questioned him why the handbook and sticker on the fuel flap both say 36 psi and was told they must be wrong as they should be 30 psi.................... Can anyone please just confirm that a 1998 A4 2.8 30v quattro with standard engine and tyres (205 55 16) should take 6 litres of oil and have tyre pressure of 36 psi before I go mad at them.
