The third person had their car serviced exclusively at the dealer. 2 of those three decided to dump the S4 and take a massive hit on trade-in, while the third has an extended warranty. All three cars are in the 70-90k mile range, too. Parts alone run $1500 for the repair and labor is astronomical on that underaking. Yet another person I know owns a B7 RS4 with less than 50k and hes having timing chain issues, though the dealer and AOA are stepping up to the plate... pricetag associated with the RS4 engine replacement? $20,000. Makes me want to start hoarding late 32v and early 40v motors!
