Yup... Fuck Audi. You should see what it takes to get to the turbos on the S4. Or the o2 sensor on a W12 A8.

These cars are made to last as long as the first owner will have them and not much longer after that. Because Audi's target demographic isn't people that buy used cars. It's people that buy new German luxury cars.

Audi both needlessly overcomplicates things and then uses cheap materials in the process. Basically the worst of all worlds.

top car/engine isn't the same as the bottom. the top pic is the procedure for doing a timing belt on a trash pile v6 audi/vw

the v8 timing chains are senselessly over complicated, and eventually fail. 30 hours of labor book time including pulling the engine. yeah, fuck all that.

But ya I don't know that I would want to go beyond the cpo warranty and most on this site don't keep cars for 6 years or rack up 100k miles depending where you picked it up at.

The Certified pre-owned program offers 6 years or 100,000 miles (whichever occurs first) of limited warranty coverage.

I'm assuming this is an interference engine too?

Yes.

What the fucking fuck. The only way that could be worse is if Audi did it with a belt so you had to change it every 60k miles.

Funny you should say that. Audi took that challenge right up until 2007 with the 4.2. Pre-2007 cars had a timing belt that required replacement every 75,000 miles.

This is why electric is the future regardless of cost. It's infinitely simpler, doesn't have the same maintenance requirements and is smoother than any gas engine. I mean you look at that picture and just think of all the things that can fail. Audi uses garbage plastic so just one broken chain guide and you're going in there to do all that work. When my janky electric motor breaks they'll pop the subframe off, bolt another one in and bob's your uncle.

This stuff looks downright archaic.

Don't have to preach about the ease of maintenance.

My RC cars all run Brushless electric systems. The torque and response is lightyears better than any nitro-methane engine. Though I miss the noise, but nothing else.
