Ball in a can kind of sound from back of engine? What's going on?

[sakimano]

Does it not sound like a broken guide to you? It sounds exactly like apat’s car did

Don’t fool yourself, the timing components are a major flaw of this engine, and you can’t just overlook them because you think it’s a rare issue that only happens to a fraction of S4’s.

I never said any of that.

I said you’re obsessed.

I think the ECMs used in the B7 and older cars use older technology so it is harder for Audi’s background software to realize changes have been done. If I remember right Audi’s TSB said something about the 2008 models were where they started the checking and other models would be added on later. Think about it this way: most all the 2007s should be out of factory warranty by now and CPO repairs have stricter guidelines so most of the warranty claims are going to be for B8 models and newer where their software can pick out the ones that try to squeeze by.

I wonder what the deal will be on this. I spoke to a tuner and they laughed at TD1 as it relates to the B6/7 saying that it can be made to show Audi whatever the tuner wants Audi to see.

Not sure on the B8 S4 and so on.

But…as you pointed out to me, or reminded my senile ass, a quick log while driving an RS will determine right quick if it is tuned. Throttle posisition % below 5Krpm, I/M flap position below 5K etc. I realize a dealer probably won’t do this to determine if the car has a tune but it seems like an obvious somewhat quick check, no?

sounds like a cam adjuster struggling. and that would explain the choppy idle and stalling. i really doubt it’s a broken guide.

There was an engine torque test that I had to do like three times before I left the dealership. It made you drive the car WOT to see if the engine torque went over what it should be. None of those cars were modded so it didn’t show anything past the spec but it would be interesting to look at the measuring value block on a heavily modded car in turbo mode using a vag-com. I wonder how far off the measuring value block is from what you are actually putting down.

Wouldn’t he have the typical code that goes along with that, and probably a flashing CEL for the misfires?

[Coderedpl]

The only codes thrown were related to o2 sensors and idle rpm too low

[tyler]

is it drivable?

I guess so but I am thinking more with respect to flashing back to stock before service

‘actual torque’ is a field you can log in Newton meters. It reads a bit lower than crank torque and higher than a dyno proper

I logged it on my car and converted to lb ft and then made a torque and HP plot

Somewhat.

is that measuring block in the engine or engine 2 module?

the older cars have it in the abs module (along with lots of other cool fields) but moving it to the engine 1/2 is interesting

[Apat]

The reason for me not thinking its a timing failure is a couple of things. The sound isn’t rhythmic and it went away. My sound was consistent, rhythmic and much louder.

Who knows though. Its a very odd sound and I’m sure not all timing related failures sound or act the same. I was lucky enough to have a failure that didn’t even throw codes. Engine ran great just made a weird ticking noise after the oil was warmed up.

I hope its something easy fingers crossed

Yes, I will confirm later which one. I’ve used it to confirm I went flashed back to stock before driving in to the .dealer. I also checked throttle position etc. I find it very useful and am happy i was told how to do this via vagcom.

Sorry Codered for the thread jack.

Keep us posted.

makes sense given the strict torque control

[Coderedpl]

Still at dealer and still no word.

[sakimano]

this will be an interesting test of TD1T10 or whatever it’s called. Basically JHM makes NO attempt to hide their tune on these cars. They change the name of the vehicle to say JHM 4.7 (or 4.8 or 5.0) right in the title so that techs will see it and the weird displacement will jump off the screen at them as weird.

[Coderedpl]

Still no word from the dealership on what the issue is.
I did call them and the guy said they are still in the diagnosis stage.

I thought maybe it’s the actual chip in the ecu but I did nothing out of the ordinary. And if it would of screwed up it would of done it a long time ago.
I was getting a load of o2 sensor codes and I forgot to disconnect them to see if it would run different.
