Audi a4 turbo chirps when car is started

Immediately after starting my car in the morning I hear 3-4 chirps coming from the rear right side of my car. The chirps sound similar to the sound when the car is locked and alarmed. Any ideas?

    I have had the same problem. More than a chirp. Loud whining. I have been told that it is the fuel pump which is in the right rear section.

Could be the belt(s).

If not that, could be a loose hose coming from the turbo. If it build boost and the hose is loose, it'll chirp. At least, it would on my turbo bike. Sounded like a balloon releasing air when the neck is pinched.

A6 turbocharged. Whyu does it smoke when it covers a 120km per hour?

I am going to say 'blown turbo'. As I understand it, they needs replacing every few years. They are susceptible to heat and incredible revolutions. They have to be lubricated, the seals go, and you get smoke.

My Audi A4 2009 makes a rattling noise on cold starts which resolves in less than 30 seconds. Dealer says its an air pump. This doesn't seem correct. The noise comes from the front of the care. Does not...

READ THIS (happy ending so far...):
audi a4 2L turbo quattro, manual transmission with 98,000 KM. Perfect conditions, no oil leaks whatsoever.

Left the car off for two weeks in very cold weather (-10C down to -25C). When I restarted, it started immediately but with heavy rattling noise due to camshaft adjuster not getting enough oil pressure. After 3 minutes of warming up (outside temp.: -12C) at very low rpm (below 2,000rpm), I start moving the car. Still hearing heavy rattle noise. As soon as I pass 2,000 rpm, I get a scary red warning, low oil pressure. Turn off the engine immediately. In 1 minute, I re-start the car and the engine lights check ok, so I drive in first gear super slow (1,200rpm) hearing the same rattling noise. After another minute, finally the noise all the sudden disappears and the car starts running just fine.

Called Audi dealer and they told me that in extreme weather conditions, I should warm the engine for 10-15 minutes if necessary before start moving.
Take away: luckily, I didn't screw up the engine since I was using it at extremely low rpm (easy to do with clutch and manual transmission) until the oil reached full pressure. I am pretty sure now that the problem was leaving the car off for such a long time in freezing weather. All the oil flows back to the bottom, and when I restarted it, the cold oil with high viscosity took a long time to reach all the parts of the engine, specially the camshaft adjusters that are actuated by using oil pressure. Next day, the car started at -9C perfectly without making any noise (as usual). Basically, the longer you leave your audi in cold weather, the longer you might hear the rattling noise until the oil reach full pressure inside the engine. My car took 6 minutes to fix it after couple of weeks in cold weather. This makes sense to me; in fact, in the past I only heard the rattling noise after leaving the car off for a couple of days in the winter.
So far, this has had an happy ending....

Well I would make sure that whoever is changing your oil is using an oil filter with an anti flow back valve. I had the same problem with a few of my car when I used filters without the anti flow back valve. I can't stand that noise when you first start it. Now I always use anti flow back filters and I never hear it anymore.

this is a common problem with volkswagon and audi cars they have what is called a secondary air injection motor which usually only works at start up .this motor goes bad and makes the sound you hear it must be replaced .it is held on with 3 ten millimeter bolts and two air plastic lines that you have to squeeze to remove and an electrical connector. goodluck.

you have a worn turbo bearing.I would get a replacment turbo before you do any damage.When you start the engine the bearings in the turbo are dry of oil.Has you start the engine the oil will reach the bearings and the noise will apear to go away.

Chirping sound after starting

Here's some info I found.
If it's when you lift off the gas, its the dv (diverter valve), it is normal. If you take the airbox cover and filter out you can hear it better. If it sounds like a splash or psshhh, its fine, if it sounds like a rapped goose, you have a blown/torn dv and it needs replacing.
If the sound is coming from the rear it could be a fuel pump.
You can get the trouble codes scanned. Many auto parts stores will have a free loaner meter you can use. Try Advance Auto, AutoZone, VIP, CarQuest etc etc.

2003 Audi A4 Cabriolet ...cooling fans come on at start up

Yes this car should have a temperature sending unit that tells the fans to kick on. If it has two fans one of them is for you Air-condiontion, and it will turn on whenever the ac is being ran. One other possibility is if you bought the audi used the owner before you may have hard wired the fan to run whenever the car ignition is turned on. The only reason someone would do that is if they were to lazy to fix it properly.
