Friend bought a used S4..

Forgot to ask the year because I was so bewildered... I believe it's 2004 or older.. Oregon plates, (rust alert) shitty black paint on what used to be gorgeous wheels, stock muffler hacked off and a flowmaster muffler has been bodged on (complete with unevenly spaced chrome DTM tips) 150,000 on the odometer, I noticed an odor of burnt oil when he surprised me by diving into my driveway last night. There's an odd whistling noise from the drivers' side of the engine bay which occurs when you're getting up in RPM's, when youi should be building boost. Will not boost over 5psi. I don't see any smoke from the exhaust, and it's not leaking oil as far as I could tell.

Friend knew this before buying it, assumed that it was a simple "boost leak" (as in, a hose or coupler is loose.) Other friend pointed out that if this were the case, he would *definitely* have thrown a check engine light by now. An opening in an intake hose would absolutely trigger a check engine light.

S4 gawds? How badly did my friend dick up here? He purchased the car intending to apply this simple fix and use it for transportation to the slopes while he dumps money on his Impreza project.. $4800, $136/month... It's a gorgeous car inside and out, paint is basically flawless... Just a hideous unpainted lip spoiler on the trunk and some light denting on the drivers side rear passenger door.

I'll have pics in a few hours.

The turbos in those were prone to failure. IIRC when they started to go they made a dentist drill type noise.

Boost leaks were also quite common.

Have you checked for codes yet? Maybe the check engine light burned out.

hadn't considered that... Would the CEL flash or come on momentarily while starting the vehicle just as kind of a bulb checking measure?

Yeah, It should. I was just considering the mileage and cheap "upgrades".

How are you measuring the boost as well?

Better to data log it and see what the computer is seeing.

He should probably invest in this if he is going to keep the car: http://www.ross-tech.com/vag-com/index.html

That will allow you to check and clear codes and also data log boost and other engine parameters.

That's what I used to use on my old S4 of the same type and what I use on my new S4.

Could be a boost leak, and that probably wouldn't cause a CEL.

do this:

Also get it checked with VCDS.
