hello I have a 2010 audi A5. Consumer Reports shows the engine as well as other components as having the lowest rating. I brought the car to an independent audi mechanic, flushed the transmission fluid at 36K miles. The mechanic pointed out some components that are known to premature failure and provided sources on the internet to confirm. 1) the PCV 2) the turbo, specifically its wastegate and actuating rod 3) the diverter valve for the turbo, it has a diaphragm that rips causing an underboost condition 4) the timing chain tensioner, which, if it fails will cause massive damage because it is an interference engine
the repair of all the above = $4K ! the car is valued at only $13K
the car works perfectly and looks very good
is spending $4000 now on the car to avoid future potential problems advisable?
should i just trade it in and buy the 2018 A5 which appears to have the bugs worked out?
or, just keep it as is, and maybe make repairs when the parts fail?
WHEN DOES ONE CUT THEIR LOSSES ON A USED CAR REQUIRING YEARLY REPAIRS?
