I'm extremely surprised by this. The 4.2 FSI is supposed to be bulletproof. It has been tested and tried in many of Audi's cars... it is about as widespread as the 2.0 TFSI, which is a very reliable engine. However, you're not the first to have experienced massive engine failure... but two in a row?

 

There are plenty of blown rotaries from Mazda, and blown up Toyota Tundra engines when they first came out. A lot of Dodge engine failures to be accounted for, especially from the Durango and the late Stratus.

 

Thats what i thought too, but speaking with the head mechanic at the dealership I was surprised to find out that 3 other cars have had major engine failure and 2 others had transmission failure and a third is showing symptoms of it, I dont know but im guessing these cars realy cant handle this weather we have hear in kuwait with the constant dust storms, could be a bad filteration system or something......ironicly we have alot of lambo's here with no problems at all....

 

Wow.....sorry to hear that get a V10.....

 

First off, there are always two sides to every story. Have you raced? What aftermaket things have you done to the car? What has the dealer said after inspecting everything? It's not just a matter of, "my car broke, I want this or that." The dealer and manufacturer needs to see and investigate this.
If all pans out legit, I'd make them get me a new car. Or at this point, I'd likely not want another R8. The fact that you want another, but with a bigger engine, scares me a little.
Good luck and keep us posted.

 

Superior German Engineering at its best! Why have the engine replaced if it's a sure shot it'll blow up again? Quit wasting your time and get something much more reliable. The R8 is a beautiful car and it looks fast standing still, but that's all it has going for it.

 

Again, we hardly have any context to this issue at all. IMO you can't make blanket statements like the ones above w/out more behind this. The 4.2FSI engine has been used for years in a number of Audi vehicles, including mass market ones.

 

I have done 2 track days on my FIRST engine and audi knew about it, they were simple track days and not a race, and for modifications the only thing done to it is a stasis exhaust, which the dealer installed for me, Stasis itself is sold throught dealerships in the US ( kinda like dinan for BMW ) and my dealer honored my warrenty with the exhaust installed since they installed it themselves......honestly the only reason I want another R8 is because the car is that good even with all the issues Im having, and the V10 is just a better version of it, I truly do love this car you cannot realy discard it till you have tried it on and off the track, thats when you realy appreciate it

 

yeah i wouldnt discount the 4.2FSI engine right away since that engine has been used in many models before like the RS4

but hope you get a nice chunk of credit towards the V10

 

Did you have to pay anything to replace the engine either time? If not, just let them replace it again. #3. Then after that complain a little more.

 

What is it with that freaking motor!!!! My brother in law blew his 4.2L in his S4 twice.......

 

The 4.2L Audi V8 has been around for a while, could it be the the FSI version is dramatically different than the Motronic/KE-Jetronic version in the fact that direct injection requires a cam-operated fuel pump? There's also been reports or hearsay that VW's having cam follower issues on the 2.0FSI as well.

And to add to that list of engine failures, let's just say GM is still having piston slap issues on the Vortec V8s and intake manifold gasket failures on their OHV V6s due to Dex-Cool eating the gaskets. Ford had some teething issues with a nylon intake manifold.

 

dont care it blows out 100 times still love me some R8...

 

Sounds like the 4.2FSI engine has a common issue... http://www.bobistheoilguy.com/forums...Number=1325647

 

Carbon build up behind the intake valves is a common with all direct injection engines.
The problem is that, with a direct injection system, the fuel is introduce in the combusion chamber, therefore the detergent in the gas cannot get behind teh vlaves to clean that area like a regular fuel injected engine. The exception is the Lexus direct injection engines, which use both direct and port injections.
