Hi

About to purchase a 2016 S5 B.5 with just over 85k miles on it. From my research the CREC engine is supposed to be more reliable than previous years.

Is it worth the gamble of potentially getting into a big money pit or should I be daily comfortable that ownership shouldn't too be too bad, relatively speaking of course
 
The CREC engine was put into production 10 years ago but not in as many models (excluded from S4 & S5 in North America). Neverthess it does seem that Audi does seem to have improved reliability as it seems there are few cases of PCV problems (oil consumption). The other major issue was timing chain tension (cold rattle) but that seemed to be only on higher mileage engines so it may not be clear if that has been fixed. The CREC has the potential of being less susceptible to carbon since it has the extra fuel injectors. Some people have had trouble with the supercharger clutch. I've had no engine problems, but my car has only just done over 32K miles.

There was a recall done for the CREC engine (fuel lines) so check that it was done on that car.
 
In the states, these CREC motors were fitted into the 2017-2018 Q7 and it has been a nightmare. Between 60-80,000 miles they develop horrid oil consumption due to packed piston rings. The one you are viewing is at 85,000 miles. What usually happens is that the previous owners realizes it's consuming oil, and then quietly trades it in without mentioning the high oil consumption. Dealer has no way to put miles on it to detect oil consumption so it gets sold with a "clean bill of health" to unsuspecting buyer, who then realizes they are having to add a quart of oil every 1000 miles. Eventually one of the cylinders loses compression due to cylinder wall scoring or an exhaust valve fails because of the carbon deposits from the oil burning preventing the valve from cooling properly.

I'd stay far away from this motor beyond 60,000 miles without a warranty that will cover piston replacement due to excessive oil consumption.
