V8 Engine Failure - Clanging / Slapping noise from engine during idle / rev

[Quack]

Firstly I wanted to point out two other engine failure posts on this site:

My R8 had low mileage on it when this issue occurred. Just 10000 kms / 6000 miles and then out the blue a faint clanging noise coming from the engine. The best way I could think to describe the noise was two pieces of large metal slapping together continuously. It sped up as I revved the engine so I assumed pistons/cylinder problems.

Anyways, it happened about 2 weeks ago on a perfectly clear and sunny Sunday. I had just washed the car and was driving it around when I heard the sound. I called Audi South Africa and they sent someone around to see if they could solve it without having to bring it into the dealer's workshop. The guy couldn't solve it so he recommended they flatbed it to the dealer.

The dealer then started the investigation which took 1.5 weeks to find the problem. They said they found metal filings in cylinder 4. They had to insert an endoscope into the engine to finally get to the potential fault.

So it's a new engine for me. Took 5 days to arrive (10 days was the max they said it would take to arrive). Should have it back in 1.5 weeks.

My advice is ask your dealer to look at this post and start off with an endoscope into the engine to see what the problem is so you can speed up the solution. I had the same wait with the dealer trying to find the problem then communicating with their head office and then finally to germany.

Audi South Africa have been brilliant throughout this whole experience though. Organised a courtesy car and when I asked that they upgrade it they gave me a choice between an S5, Q7, S6. I'm a TT fan so the closest I could get to a small car was the S5

I'll try to get some pictures of the engine filings but i think they're probably going to be the same as the above picture. I'll see if I can get a recording of the engine noise which should help some of you identify the problem.

Hope this helps.

Thanks for the post..as you might already be aware I lost a engine in exactly the same way.

Glad to see Audi was excellent... like in my case

Would be good to see if these problems are coming from a particular build date.

What year is your R8 and do you know what month it was built?

Sorry to hear about that Quack. I am glad you have had a swift resolution and will be back behind the wheel soon!

threads like these scare me re: getting a SC or TT

Hi guys,

Sorry I've taken so long to reply. It's been a busy week.

They've started the install today. I should be getting it back this week

Can't wait.

I incorrectly put in the second URL for the engine failures. Here's Gazza's post:

Will update you guys as the news comes in.

dont know if uve seen my thread but ive already gone through 2 engines and the car is on its third......i guess the v8 is having major engine faliures

[Quack]

That's not good news. Well the engine they're putting in now is the 2010 engine so I hope they've worked out the kinks by now.

I don't get it though. They've had this engine around for ages with RS4. Why the issues now. I haven't searched for RS4 Engine Failures but it just seems odd that an engine that's been around for that long would have this problem on a different chassis/gearbox.

Well, right now. I just want it back. Hope you're going well with your third engine. How's it been so far? Have you had any issues with the installation?

quack, i no longer have the car the dealer opted to buy it back and im upgrading to the v10, i realy dont know why the major engine problems it could be the engine was not designed to be a dry sump engine.....i think my second engine problem was actualy caused by the dealers install rather than a faulty engine, ive heard that if an engine was not mated to the tranny properly it would cause stress on the crank shaft and it will eventualy break.....and thats exactly what happened to my car......so instead of waiting and seeing if they got it right the third time around i went with the V10 instead
