When you think of unreliable Audi engines, which ones come to mind? Off the top of your head, you’re probably thinking of the B7 Audi S4’s 4.2 liter V8 or the B5 S4’s 2.7 liter twin-turbo V6. Typically, modern 2.0 liter TFSI engines aren’t considered unreliable, as they’re typically considered to be relatively simple, durable engines. However, according to Consumer Reports, the B8 Audi A4 has actually a rather problematic engine.
More specifically, it’s the 2009-2010 Audi A4 models with anywhere between 107,000 and 153,000 miles. Admittedly, that’s some high-mileage, so its no surprise that a few things go wrong. However, CR noted an extremely high number of claims from customers with this engine.
This is honestly news to us, as we haven’t heard a ton of complaints for the B8 Audi A4. Not that that means this report is wrong, as we aren’t saying that at all, but it proves that even cars without long histories of unreliability can be problematic.
What’s interesting is that CR only reports that the 2009 and 2010 model year cars were really bad. So it’s possible that there were some issues that Audi remedies after a few years, possible after the mid-cycle facelift.
The B8 Audi A4 is a good car and one that’s coming down in price drastically as of late. You can find nice examples for well under $10,000 and it’s also the last generation of A4 Avant in America. So if you can find a nice B8 A4 Avant, from 2011 or later, it’s absolutely a car worth getting. According this report, just stay away from 2009 and 2010 model year cars. We’re also assuming that the B8 Audi A5 Coupe from those two years is in that mix, being that they’re mechanically almost identical. After 2010, though, this report seems to claim that B8 model Audi are just fine.
