I phoned audi in reading and they game me these details
OIL GO 52 162 A2 £11.93 + VAT
Filter 01 L 325 429 AA £36.55 + VAT
Seal O1 L 325 443 £2.66 + VAT
Gasket 01 L 321 371 £23.03 + VAT
so more inline with that IT said.
Any one know if there an equivalent to GO 52 162 A2, i think Esso LT 71141 is the only equivalent making it pointless as its not for sale anywhere.
http://www.ebay.co.uk/itm/Mobil-Esso...item1e6c4504bf this is only £1 or £2 quid cheaper. So audi oil seems best option regardless.
i can run a cheaper version for 5-10K and then dump it.
Would help if the audi dealers actually new in the first place.
