Reviews of OEM Audi oil pump

My 07 a8l is at 177k at 100k had to walnut blast then again at 170k. 2 ac valves went and last week an oil pump went.

I would add the chain driven oil pump to the Con side. The internal chain is more susceptible to failure and has higher maintenance cost. these motors are notorious for the chain guilds wearing out clogging the oil pump pickup and starving the head, turbo and motor of oil pressure causing an expensive repair. ask anyone you know who owns one. My friend with a 1.8T Audi has had this happen twice in 2 years. another thing to consider is internal timing chain = higher maintenance cost.
