View Full Version : Revo chipping 2.0T FSI. Strange whistling noise

The car has 10 k miles and was chipped at 3k miles with Revo on 91 octane program. Lately, the car has been making a whistling sound coming as it appears from the turbo itself. Their is a noticeable lag and power shortage. A few days ago, the car was diagnosed at the dealership but they couldn't find anything. The smoke and dye test were performed to find traces of any leaks. Their were no leaks detected. CEL light is not on. A friend of mine said that it is the noise of a turbo grinding. Has anybody experienced the same sitiation? I can need some advice from you guys since I am upset and frustrated. Is the revo program that unreliable?

i got almost 35k miles.. and chipped since around 1500 (REVO stage II)
no problems whatsoever.. but i never drive hard..
i got a whistling sound right now coming out of my speakers.. but thats because i just installed a DVD player.. where is your sound coming from? did you install anything else in your car?
you cannot blame the problem 'entirely' on the software. there's other things you need to also factor in that cause this misfortune...driving style, inappropriate warm-up/shutdown, other modifications, etc...
best way to check is probably pulling the turbo out.
good luck.

The car was driven hard but with proper warm up and cool down procedures. Mods are intake and exhaust. I still think that a k03 should last longer than 7k miles chipped

^^^^^^^^ I agree with LAS.
I'm an APR fan myself, but I think that it's inappropriate to come on the forum and bash REVO because you hear "a whistling sound".......and because a friend of yours told you that "it's the turbo grinding". [rolleyes]
There could be a million other factors at play here.
Have you gone crazy with the settings on the REVO?
Have you been driving the ever-luvin' piss out of the car? (sort of just answered above)
Have you maintained a healthy amount for all of the fluids in the engine?
Have you let the car cool before you turn it off after a round of spirited driving? (just answered above)
Have you had any other engine related issues before this?
Do you live near powerlines?
Have you ever eaten paint chips?
.....etc.

the sound of a failing k03 is fairly distintive and goes with the loss of power you are mentioning. if that was the case though, the dealer should have been able to tell. when failing the turbo gets extra loud and tends to fade in and out, sometimes spool, sometimes not. but thats just in my experience.
do some logging, see what comes up.
and yeah, blaming it on revo might be a little premature. granted, running extra boost is def. not turbo healthy, it doesn't mean it's shitty software. then again, i know you can raise boost higher with revo than with other vendors (ex. APR), depending on how high you were set, it may not have helped your cause.

revo since 200 miles hehe =]
and revo stage II since 1k miles
i currently have 10,300 miles on my car and no problems!

The car only has 10 k miles, keep that in mind so fluids are very fine. (double-checked). The settings were the ones that came when they chipped the car. (I do not have sps module).

as mentioned on audiworld, you need to check your DV, it would be a much more likely failure with basically the same symptoms (as it is impossible to describe the difference in turbo failure sound and a dv whistle online)

x2. my money is on the dv. and that's a hell of a title, considering you have no idea what's wrong. a dealer tech would have definitely diagnosed a blown turbo. on the other hand, any good one would've check the dv. but still check it out.

X2 on the DV. Check it as the factory one is known to fail on chipped cars.

wow the assumptions are running thick in these forums today...
I really hope this title gets edited.
If you had a blown turbo you would notice... you would have an ungodly grinding sound in your engine bay - horrible performance and flashing CEL's everywhere.
The DV gasket failure is pretty common and happens on a lot of chipped cars due to increased boost. It sounds like your dealership just over looked this. There is no way they would get away with 'missing' a 'blown turbo'....

Check your blinker fluid... I go with the synthetic... It's a little more, but the performance makes it worthwhile.

But with a worthwhile point, I don't think its the same sound, but theres a crazy whistle at full throttle coming from what sound like my exhaust, I'm guessing its a leaky DV... Gotta get it checked out.

x 5 DV...PCV Breather pipe...it's all in one package.
If you are hearing those whistling sound and if you can find engine oil pumped out near your oil cap. it is most likely the same problem that I had.
Just got the car back from the dealer. No more whistle sound.
It will be covered under your warranty.[wrench]
too bad. I have to go ICS again, b/c they flashed my programs...[=(]

recirculating valve malfuction N75 and 3 out of 4 coil packs are defective
glad to hear it wasn't your turbo. If you don't mind me asking, how much was it to replace everything?
Hmm, maybe I should buy an extra DV and coil pack just to in case.

Well unfortunately I have bad news. The dv was replaced and all 4 coils but the lack of power seems imminent. The noise isn't gone and sounds like the "dentist drill". The car didn't show ant leakage with the dye test. I really hope it is not a k03 failure at 10 k miles.

A buddy of mine blew his k04 on a mk1 TT 225 a few years back. Sounded exactly like a dentist's drill.
Good luck [up]

Well went to the drags to see what my car is capable of doing. My 3 runs were consistent 15.7s @92 mph. The car is 6 speed manual revo stage 2, intake and exhaust. I am guessing the turbo is at its dying stages.

So no luck, I don't have access to a vag-com. The engine is shaking at idle, the car sometimes shakes a lot and a louder exhaust note is heard. Cel light is on and sometimes flashes. Their is also lack of power and a whistling sound coming from the engine bay. I am frustrated because the dealer can't seem to find the problem. How do you know if your valves are bent? What symptoms should I look for? And also, would vag-com tell me if I had a boost leak?

Sounds like an intake air leak. A bad turbo won't cause shaking idle.
I've had 2 turbo's go out, one on an Audi, one in a Mits. Neither shook at idle. In fact, both idled normally. Power seemed a bit flat just before they died. When they died power was no more. It feels worse than the stock engines, obviously. However, no shaking idle or rattling.
Check the heat shields for sources of rattling, and have the codes read again. If there are codes then there are problems with a flag.
Take care of that first.
Check the clamps to the IC's, in and out.
You can test for an intake lead with a can of propane, like the kind plumbers use, or the Audi tech can do it. You can also use compressed air. While the car is idling you spray some propane around the intake manifold and associated areas where air can get it. If at any spot the engine surges (rpm goes up) you have found you air leak.
If you use compressed air, just keep a look out for changes in idle and rpm. If you find the air leak, repair it.
I had an air leak on my turbo and the idle was poor and shaky, and there was a slight whistle especially when giving some throttle. It whistled as the air went through and in the leaking area.
I had to take the intake manifold out and put on a new gasket. Problem fixed.

fast_audi I feel your pain. I have a 2007 2.0t with Revo stage 1(not pointing any fingers, just showing similarities). I was chipped at around 3500 miles. I now have about 12k on it. I noticed a small whistle from the left side of my engine bay when I would accelerate. I also noticed a lack of power in the lower rpm range. I went to get my oil changed, and the technician called me to show me all the oil around my filler cap(not at the dealership). I took it into the Audi dealership and they called me to tell me "the filler cap is not sealing". They replaced it yesterday and I went to pick up my car. I got home from work today and smelled oil burning. Pop the hood and more oil around the filler cap. The invoice the dealership gave me says they just replaced the valve cover nothing about a filler cap, just read the invoice today. Needless to say I will be spending my Friday morning at the dealership.
fast_audi please keep me posted on your situation and I will do the same for you.

Well, I had the same thing oil around the oil engine cover cap. They said it was the oil cap seal and they changed the seal and brought me a new oil cap. For now that problem is fixed. My Dv got replaced last week as it was torn. I just got a call from the dealer and they said that the wastegate of the turbo failed. They will cover 100% under warranty. I am happy with their service but Its annoying to be there all the time.

yes the kk3 turbo OEM Audi was blown with a revo chip and exhaust after 1 -2 months of chipping. It could have been an coincidental situation, maybe the turbo might have gone bad even without a chip. who knows...
