Oil for Audi/VW 1.8T

[v6ter]

Hope someone can help

In my manual for the A3 it states that the recommended oil is VW spec 503.00 or 503.01

In Halfords Castrol 5W-30W is £45.00!

The question I have is I have also seen Texaco Havoline 5W-40W Which is vw 504.00, I have heard that this supercedes the previous numbers and is ok to use, is this correct?

Thanks for that

I have found a TPS in Stoke, so will try there. Thanks again

UPDATE

Just called them and they say they only supply to the trade and I need to go to Audi!
