One nice thing about the A4 (all Audi's I believe) is it had an oil level light that came on when down 1 quart. It also held a lot of oil (German engineering). I would check the oil prior to any road trip, but a couple of times I forgot and the light reminded me.A very good reason to check oil levels regularly.
There are issues in addition to running oil low and seizing pistons.
How many miles on the engine?
Did the plugs have any oil residue?
Any cat converter issues?
I worked my 1973 Datsun PL 620 hard, before installing a V8 in 1982.
Picture it loaded with two dirt bikes, pulling the I5 Grapevine at 80 MPH in 3rd gear (4 speed).
At 100,500 miles, that 1.6 L used less than 1/4 quart between 3,000 mile oil changes.
No engine service other than tune-ups...which were SO easy!
It then saw further service in a neighbor's newer Datsun.
never had any cat issues, plugs looked real good - only changed them once. I sold the car to my neighbor with 77,000 and he has had it for four years and still runs great.
I would have preferred that it not burned oil and I was considering a Q5 when I got the Soul and my service rep actually told me to avoid the 2.0T due too oil consumption and go with the V6. Maybe that was good advice, but there are a lot of 2.0Ts out there and people, including me, love them - even if they eat some oil.
