just brought my first audi. now these are the questions if anyone can help? What oil should be used as heard you should only use a certain type? Is it worth putting a oil catch tank on as i like the look of them in the bay and if so which one should i buy? I want a dump valve but heard you need a recirc one? the forge 007, does it make a dumping noise or cant you hear it? a rough price on a cambelt change? 300-350 pounds sound about right?? anyone got a link to a good fmic for the a3 and also a guide or information on how to do it? last but not least the exhaust, i am going to take it for a remap after all is done, i dont want it to be loud though i would rather it purrr if you know what i mean? any ideas on what to do? I think that is all but if anyone has any good ideas on what else to do as in upgrades before a re-map that isnt to much money please let me know. the audi is a 2003 AUM engine and is a sport with the k03s turbo. cheers in advance tom.
