Possible popped motor in an APR S2 B8? Anyone heard or know anything about this?

B8 S4

Well according to our good friends at EC, it’s pretty much always the users fault…

“I personally have never lost a motor due to any manufacturers software, nor would I personally every put the blame on a particular software. Even if the software is less than safe to be operating in extreme conditions, it is ultimately the vehicle operators fault.”

That is fucking hilarious… Yep my fault I took my $1,500 tuned S4/6 to the strip and well unfortunately it popped… We(the $1,500 customer) should log first right, EC? Is that what you tell the folks you flash? Those tuners would never run anything unsafe, right? Wonder if he has ever seen Revo S4 logs?

Saw that too, didn’t expect it. I should have though. They are a shop and need to make it look like only idiots blow motors and their brands are all perfect.

#26

Not sure what he was getting at about cylinders being lubricated with fuel, lol wtf…ummm opposite thing…

But one thing I did notice, this

[QUOTE=Info@EuroCode;9087548]We have recently rebuilt three 2.0TFSI longitudinal motors, two of which were 100% stock and one which was programmed.

There is a known issue in which the injectors are getting stuck open, the end result is cracked piston rings. The longitudinal engine also suffers from oil consumption problems which are directly related to the pistons that were used in the 2009-2010 MY
[/quote]
The 3 3.0TFSI motors that were blown on REVO all had leaking FSI injectors, as told to me by both Audi and REVO. I think all 2010 cars…Wonder if the tune is causing damage to the injector itself…

Arin…thoughts?

#27

dunno

#28

This thread needs a title change.

My 2009 b8 a4 avant had its pistons replaced (among other things) under warranty. They used a redesigned version after excess oil consumption caused by ring damage, exactly as mentioned above. Didn’t know it was an injector issue.

#29

The oil consumption issue and injector TSB are mutually exclusive.

Early B8 A4 2.0T (valve-lift) used a piston that was lighter in weight than the transverse motors, and the piston itself is the culprit on the oil consumption. It changes shape/size under heat and the by product of this is oil blow by.

We have seen quite a few cars that suffer from the oil consumption issue, most of them are able to be repaired at the dealership under the extended warranty, we have done the rebuilds for a couple of customers that were out of the warranty.

The fix for this is to replace the pistons and piston rings with the pistons and rings out of the transverse engine.

The injector getting stuck is one Achilles heel on the long. valve-lift motor as well as the hydraulic timing chain guide tensioner.

#30

That is odd because I remember Audi telling the TFMs and the dealerships that the PCV valve would cause the early 2.0 TFSI piston rings to flutter.

They changed the repair procedure a few times for customer satisfaction reasons. But shortly before I left there was a updated TSB that came out saying to replace the PCV valve and front crank seal then do a software update to make it work right. Then if the engine still burned oil they would have to replace the pistons and rings from the updated engine because the damage was already done so to speak.

#31

They call that the part one oil consumption test, and in my opinion they are just buying time with the customer. It is a shame because the customer has to jump through many hoops.

When it is all said and done, replacing the rings and pistons is the only real answer. Audi should have reman long blocks ready to go to exchange out like they did with the sludge 1.8Ts

^^ we shld have your handle changed so that it reads “Greg@Eurocode”

This is shady man. The other sponsors on this site own up to who they represent. Not you, apparently.

#33

Clochner, It’s even worse on vendorzine where he posts under his EC handle and also under the 500HPS5 handle… You know this allows for more unbiased reviews of those 3.0 headers that make massive power or the intake that makes 15HP and increases fuel economy by 40 miles per tank… But hey Anthony and his crew of mall cops allow it so why not as I’m sure it helps sales of their products which is the only reason he is posting anyway… Don’t worry he won’t hang around here since no one will buy his sales spin… He’s just here to set us straight on his wife’s BS because none of us were smart enough to figure it out ::slight_smile:

#34

Just to go back to the title of the thread…eventually, someone’s gonna ‘pop’ another motor. Wonder if it will blow up into a finger-pointing blame game, will be fun to watch…:slight_smile:

Even from my experience of blowing a motor, I’ll never know if the tune was fully to blame, which in hindsight made it a decent reason to keep it off the forums and only tell a few people.

#35

Why does not that not surprise me. Most of the aftermarket is uninformed. On the OEM’s scale of paying for warranty repairs it is better to fix the cause of the problem then fix any collateral damage that is caused by the original problem. Plus it saves them money in the long run. But an aftermarket shop especially a shady one like EuroCode would rather Audi just dumps a brand new engine in at the drop of the hat but then they bankrupt themselves in the process.

Seriously own the fact that you are from EuroCode like changing your name or put it in your signature with huge font.

Well I won’t say who’s logs were shared with me but based upon the timing values I would say the tune was at minimum a major contributor especially since I believe that owner did quite a few back to back 1/4 mile passes… IAT’s kept climbing into the 70’s(almost 80’s on a few passes) as I recall and not much timing pull… That’s when the misfire detections started to pop up and up…

#37

[quote=“primetime,post:36,topic:4635”]

wait, so someone was logging and saw this and kept pushing the car? Or did they see this after the problem?

#38

[quote=“sakimano,post:37,topic:4635”]
Honestly, not sure I wasn’t there at the strip… If I am hot lapping which I try to do in the cooler months as the car perfoms better I don’t review logs until a take a break or go home… That would be my guess…

#39

[quote=“primetime,post:38,topic:4635”]

Lol…you guys have both seen the logs, I’ve sent to you too Sak. No I never looked at the logs during, I was too busy racing the CTS-V next to me, and getting some good GoPro vid of it. The terminal misfire came on the last of 3 hot lap sessions, 7th or 8th run total, it had cooled to about 20 degrees C by then. Even then, it made it through the run, and the misfire happened at the timing booth.

I wish someone would come up with a better logging solution than VCDS. It really sucks. Hint hint Arin what about that iPhone app…

#40

I don’t think you sent it to me (or that I looked at it)

this is you? Thought he was talking about something else.

#41

My email shows I sent it to you twice, most recently Jan 15th this year.

#42

^^^shows how interested I was

I believe around then, the NY guys (tsivas et al) posted REVO logs pouring through the parameters compared to APR GIAC, so that was enough for me.

#43

Sorry J, you mentioned getting the thread on track and I don’t think will hear from tracee’s husband again… IMO I think the tune was at fault but that is just an opinion… Yes, to your point the knock readings didn’t happen until later runs… Ill be honest I wouldn’t have caught them… Was a hot day if I remember correctly and i am sure iats contributed… Oh and I have other logs as well and pretty sure others do as well… ;D

On a side note if/when I blow the motor I would probably have one built…
