BMW 3-Series vs. Audi A4 / S4 / RS4 Reliability Comparisons

You won't find BMW 3-Series or Audi A4 / S4 / RS4 reliability information like this anywhere else. Actual repair frequencies, not just vague dots, to make it clear how much the BMW 3-Series and the Audi A4 / S4 / RS4 truly differ in reliability.

These stats are promptly updated four times a year, to much more closely track BMW 3-Series and Audi A4 / S4 / RS4 reliability as the cars age. Others tell you how reliable the BMW 3-Series and the Audi A4 / S4 / RS4 were a year ago, when the cars were a year younger and had 12,000 fewer miles on them. Only TrueDelta tells you how reliable the BMW 3-Series and the Audi A4 / S4 / RS4 have been recently.

BMW 3-Series Reliability and Durability: Pros

2012 4dr Sedan turbocharged 240hp 2.0L I4
8-speed shiftable automatic RWD
I traded in a 2005 BMW with 92,000 miles on it, if the realiability of the old one is any indication to the experience I hope to have with the 2012, then I have little to nothing to worry about.
2011 2dr Coupe turbocharged 300hp 3.0L I6
6-speed shiftable automatic AWD
All things aside it boils down to reliability. I previously owned a 2009 335 (same color combo and options) and didnt have one issue. This one however: the water pump went last month @ under 50k miles, the fuel pump also went approx 2 months earlier, the VANOS bolts needed to be replaced, an oil leak after the dealer serviced the vehicle (and no they still charged me) and there was one more episode of limp at home mode which I don't recall. The plus side it's a cpo so the bulk cost nothing. The last few trips cost $50 plus tax a pop. I would not ever recommend anyone purchasing this car without the CPO warranty. example the water pump and labor hovers around a grand to replace. Wheels And Tires - the summer tires are especially prone to road damage. I replaced all 4 tires not due to wear but due to potholes and other hazards... To which any other normal car wouldnt have an issue...
2009 0 My car has been very reliable. I got a cerfited pre owned so all things a free at dealer. If you are buying one, then get a cpo one. well worth it.

Have owned this car for 5 years; have had two replacement high pressure fuel pumps; replaced steering rack; new turbo gaskets (both turbos); replaced articulating hard top cables - all in the first 3 years and all under warranty! Nothing has gone wrong in the past two years so perhaps this was relatively new model growing pains.

I'm a little nervous about repair costs and frequency. I keep reading about 4-figure repair bills, but there are others who say they've done well with just normal maintenance. Consumer Reports gives the 2010 328i a lot of red dots which is a goo
2010 4dr Sedan 230-horsepower 3.0L I6

Small things keep breaking or failing. The engine and drivetrain are solid though.

More prone to breakdowns than the Japanese competition.
2009 4dr Sedan turbocharged 265hp 3.0L I6 Diesel

Always a glitch or two.
2009 2dr Coupe turbocharged 300hp 3.0L I6

Fuel pump, oil cooler, and run flat tire issues on the 335i turned me off. Will likely be covered by warranty, but met multiple people who had week long+ repairs for these issues. After warranty, 1,200+ for each of these issues is apparently common.
2008 2dr Hardtop conv. turbocharged 300hp 3.0L I6

Average is not good enough for a $40K+ car.

This Car is like a bad Girlfriend, Very Exciting, take her places, give her status, give her lots of money, Lots. And give her love, lots of Love ... and she just won't love you back. Two complete engine failures due to rings. And this car was maintained meticulously with 5w-30w Synthetic Oil . Complete engine Replacement at 89,000 miles due to piston ring failure in Cyl. #4. $9,000 Complete engine Replacement AGAIN at 116,000 due to Piston Ring Failure in Cyl. #2. This is a 2013 car. 3 years old. 2.0 Turbo Engine A new Audi crate engine is about $7,200 just for the engine. Then of course there is dealer labor and add ons. Just now quoted at $3,700 labor. You do the math. Here is the double cool part. A factory engine in a factory car has a 50,000 mile warranty. A factory engine installed by the Audi technician at an Audi Dealership, 12,000 mile warranty. If I was racing this car on the track I could accept those kinds of engine failure numbers. But I'm an "old guy" just doing average city and freeway driving.

2006 4dr Sedan turbocharged 200hp 2.0L I4
6-speed shiftable automatic AWD
Dont walk; Run from any 4 cylinder Audi. There are many better alternatives. The engine block is solid; Everything attached to it is waiting to fail, usually with collateral damage. 5,000 USD has been spent over years 2013-2015 for service with a Audi/VW ASE INDI shop charging conservativly (due to the frequency I was forced to visit). Many interior trim pieces, while soft to the touch, are begining to seperate and fail. Sunroof rattles all the time. Power seats worked in some directions. Handy under storage seat bins were a nice addition. Timing belt service requies removal on the entire front clip, headlamps, crash bar, radiator, etc. The 2.0 also employs a timing chain on the rear of the engine driven by the exhaust camshaft (itself driven by the timing belt), which drives the intake camshaft and houses a variable valve timing unit. The chain and tensioner assy. are prone to failure after 110k and should be replaced along with the high pressure pump's cam follower. This 15-20$ follower is the achilees tendon of the entire cam-tower & pistons, I've seen the black protective coating worn away within 5k miles on my car. After the black surface coating is worn away, the cam lob begins shave the metal surface of the cam follower, dropping the metal shards into the oil flow. Fuel also mixes with the oil commonly at this pump due to seal failure inside the pump housing. Oil change intervals should not exceed 5k miles for this engine. Evap emissions system is effectively useless as the manufactorer has shipped/contiues to ship known sub-par components (leak-check pump & assy.), which causes intermittent MIL warnings and continued, pending OBD codes.Eventually, after 10-15k miles the vacuum's check control pump fails completely and requires replacement or a constant check engine lamp and lowered MPG's/hp. The faulty system will not pass an emissions inspection until replaced with a new, less broken unit from the dealer.

Not reliable, lots of dealer visits,

Do not buy one of these used unless the timing chain pre-tensioners have been replaced. There are a lot of complaints of these breaking at 100,000 miles. Mine went at 99,100 miles and the dealer quoted me $10,000 to fix. I had to sell this car at a loss. What a waste!

The two cars I looked at were low mileage 2005s, CPO, and both had full service history, of which there was a lot. Both cars noted cooling issues and problems with the steering system repaired under warranty. Also numerous electrical problems.
