    hi i have a 100 avant with a 2.8 v6 24 v in it it is a new ish engine cos the cambelt snaped on my old one what i want to ask is what should the oil presser gauge reade on it cos my is well over 5 bar or psi what ever it i just that with my old engine it would sit at about 5 with revs and 4- 4.5 on tickever so if any one could tell me if the gauge need resetting or if each gauge need setting to each engine

    The gauge gets its reading from the sender unit, and that simply measures the pressure. You will probably notice a drop in pressure once your new oil gets a few hundred miles use. If you are worried about it, have a word with your local Audi dealer.

    Whats the mileage on the engine you got ?
    The 2.8 which i have just sold yahooo!! the oil pressure sat about 5Bar when cold and 3Bar when warmed up (ticking over) and thats standard for that engine when run in
    Note make sure there is not to much oil in engine because that can cause that to happen
    Sounds like sender unit problem if anything
    With all the stuff you doing on car you will be master of that model,Did you fit the engine yourself?
