2000 Audi A4 quattro with abrupt gear shifting & low oil pressure

My gears started shifting with delay and very abruptly in my 2000 audi A4 quattro, after oil change. Also, last week while I was driving, my low oil pressure light came on, so I stopped as advised by the manual, then got back on the road and sign would come back on and off. Then two days later I noticed that the engine started rattling, even though the oil level is good. Now I see a white smoke coming out of the exhaust with engine still rattling. So now I am afraid to drive the car and damage something else. What do you think could be the problem(s)?

    So you do not think that it might have something to do with the oil pump, do you?

I hope that you had the proper weight oil installed, at your oil change. If your oil is up to the proper level, and it's rattling ,this is VERY bad. White smoke usually means steam in the exhaust, and that means a blown head gasket. Check your coolant level. I wouldn't drive it anymore......until someone knowledgeable can diagnose it!!!!!

    I really think the problem is overheating. When the engine get to hot. the oil thins out, and the oil lite will go on and off. The transmission operation relies on proper vacuum to shfit correctly. If the car is overheated, the vacuum becomes irratic, thus the transmission operation does too.

1998 audi a4 quattro sticks in first gear when drifting down hill, shifts with pressing on gas pedal a little


Check your transmission fluid. If you have not changed it in 75,000 miles change it. This is the cheapest fix before you look at more expensive repairs.

The transmission of my A4 2.4 Audi does not shift. I replaced the gearbox speed sensor. However, I experienced the same symptoms after 30 miles driving. Please your assistance is highly appreciated.


Make sure you have sufficient gear oil (ATF) in the transmission, an Auto box uses oil pressure to shift gears. Often after the trasnsission has been removed and re fitted it will work out all the air within the first test drive thus the oil level drops too low to shift gears.

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....

A4 Transmission shifting


Fist thing to do is change the transmission fluid and filter. Audi says the transmissions have lifetime fluid, but that's bull - change it first and see if that helps. If not, have the car scanned by a shop and have the chassis codes looked into. If there's a true electrical control problem, there should be at least one code stored (which may not trip the check-engine light).
