Question about 2001 Audi A4

1 Answer

When I start up my 2002 A4 Turbo Quattro there is a very loud noise coming from the top of the engine where the oil goes in and I am now getting severe loss of power. Could this be due to me overfilling with oil?

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.

Why does my 2002 audi a4 quattro blow white smoke from the exhaust and from oil cap?, i replaced the engine head and turbo not long ago and it started out of nowhere


Sounds like a cracked piston ring to me. If you didn't do a re-ring when the head and turbo work was done, you probably should have. Now it may be too late.

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....

It appears that the bearing and seal on the turbine shaft of the Turbo have failed causing the noise of a worn bearing and oil leaking past the seal into the exhaust system. Continuing to drive it will eventually remove all oil from engine if not topped up. The Turbo needs repairing urgently before any more damage occurs.
Turbos get very hot during brisk driving and need to be allowed to cool down before turning off the engine to prolong bearing and seal life. It is recommended to allow engine to idle for at least three minutes before switching off to allow the circulating oil to bring turbo down to a reasonable temperature.

I have a 2001 audi a4..When I crank it up the turbo makes a awful screaming sound for 2 to 3 minutes then it stops.How can I fix it?


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.

2002 audi a4 oil light issue


There are potentially two different problems here.
1. A fault with the actual oil pressure.
2. An electrical fault with the switching circuit.

If you are confident the problem is not with the oil pressure, disconnect the wiring from the switch for a period of time. If the light still comes on periodically the fault must be with the wiring circuit shorting to earth. There will be no fire hazard to this approach as the voltage will drop over dash lamp.

However if the problem is with the oil supply system, the danger with this approach is you are potentially unaware of a serious problem

Such as the oil filter collapsed or the oil pressure release spring could be jammed open/closed which would cause the engine to not have the correct operating pressure.

ThenI start my engine it sounds like diesel and no power


how is the oil level and pressure?, how many miles on engine? is this a loud knock or rather a clatter/ticking noise? knock is engine rod or crankshaft bearings, clatter loud ticking is valve follower noise. how long before it (the noise) goes away?

Knocking when first start engine


Depending on the period of time and intensity of the knock ? If it is a rapid short ,loud knock then disappears altogether you may be dealing with a cam chain tensioner that is loosing oil pressure when the car is standing. A loose cambelt tensioner can increase the noise .
