I made the mistake of not coming here first for some insite into what to look out for when buying an Audi. I have driven A3 for years but not owned any of them, so I have a fair idea. The funny thing is I started experiencing problems almost from day one. It went into limp mode after 30 miles (EPC) and blowing on three cylinders, coil blown and spark plugs needed to be replaced. The dealer agreed to sort it out. I have a couple of questions, I have noticed it is consuming oil at a heavy rate at 1ltr in about 200 miles and it I get a puff of smoke in 2nd at 3000. Now the garage who I called said that it needs a thicker oil instead of 5w 30 they would throw in 10 20. Is this a wise move? The dealer has said that it is under warranty, but with all things like this is proving that there is an issue. He's asking me to monitor how long 1ltr of oil lasts. When I put it into reverse there is a slight judder when steering in both directions, the dealer attributed that to it having big wheels on it. I look forward to hearing from any body who might be able advise me. The mileage is 50k.
