Question about 2006 Audi A4

06 A4 2.0t and the engine sounds like a diesel

I have an audi 2006 a4 2.0t and the engine sounds like a diesel, and makes tapping noises, i had it inspected by 2 different audi dealerships and they told me to ignore it until it gets worse or a engine light comes on. I didnt really believe what they were telling me so i took it to my own mechanic who does import cars, he told me the engine should be very quiet, and something is mechanicall wrong with the engine, like a piston for exp.. and that i would most likely need a brand new engine. However, I heard the mechanics at audi hate warranty work and will avoid it because they dont make as much money from it. Anyone having the same problem or has had this happen? any solutions or what it could be?> thanks

    So i took the car into Audi, they had to basically take the whole top portion of the engine apart, anways it ended up being the camshaft! the car still does feel like i have to hit the gas hard to get it moving.

It may be a lifter tick, HOPEFULLY not a rod knock. However you would not need a brand new engine if either of those were the case. If you find someone that can rebuild the engine, that may or may not be cheaper depending on the dealer and parts that need to be replaced. It could also be the timing belt. The shop told you to wait for a check engine light because they dont know what's wrong with it, without plugging it into their computer. But you should NOT ignore it. Hope this helps.

    Rod knock is very much not likely with an engine in a car this new. BUT it happens, it is esentially rod bearing material that has been worn away, allowing the piston to whack the cylinder head in addition to the big end of the connecting rod banging on the crankshaft rod journal. Let's hope like I said that its not a rod knock. The best bet would be yeah, take it to the dealer and tell them no you won't ignore it. They want it to get worse so you do more damage to the drivetrain so in turn they can charge you more to fix the problem.

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.

Audi a4 1998 tapping noise only when idles under valve cover

Sounds like a bad valve lifter or a valve out of adjustment. It's probably a bad hydraulic valve lifter. In idle, when the oil pressure is lowest, it is not filling with oil. When the motor revs up, oil pressure rises and fills the faulty lifter.
If you do have mechanical lifters, the valve is probably out of adjustment. If you do car work, pull the valve cover and see if it's adjustable. Of course, you'll need the specs from VW/Audi.
Otherwise, it's probably a shop job.

I have a 2006 audi a4 with 2.0 turbo engine.I am the first owner of the car, right now it has 43000 miles on it.Sometimes when I start the car I hear a high frequency ticking sound same as the sound the...

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.

I have a 2006 Audi A4. Weird noise.

Could be a broken motor mount, so that one of the pulleys is scraping a shroud or some other fixed item.
Examine the area around the pulleys and see if there is bare metal below one of them.
If so, have the motor mounts checked.
