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.

I'm wondering whether on my 2003 (B6) S4 4,2l V8 cylinder n. 4 is the fourth one (front to rear) on left bank or the second on the right one. This just to understand the real firing order. Thank...


Firing order for 2003 (B6) Audi S4 4,2l V8 engine is: 1 - 5 - 4 - 8 - 6 - 3 - 7 - 2
Cylinder no.# 1 is first one from right front side of the car, and cylinder no.# 4 is the fourth one (front to rear) on the right bank of cylinder block. See picture below:

2005 Audi A4 1.8T QT, cylinder 4 misfire p0304


I too have the same problem on my 2005 1.8t B6. I noticed a hole in the breather hose coming off the valve cover that runs to another port under the intake manifold. I have the hoses on order and should be here on Wednesday. I'll post again if that fixes my problem.

Fuel pump squeaking, filter resticted or pump failing?


Yes, it could be the fuel filter, but the pump may be on the way out also. Change the filter first. I have seen the pump get replaced and a noise still exists. It usually caused by the fuel filter.

Bad catalyc converter! audi s4 b6


Sounds like **** to me. Did they do a compression test to determine this? Cat Converter can't cause a misfire on one cylinder. It is more likely a plug, coil, or fuel injector. Get a second opinion!

the car might still be under warranty. if you bought it as a certified used car they add on 25,000 miles to the existing 50,000 miles. If cylinder 1 is coming up misfire and your mechanic sees something wrong in that cylinder there most likely is some truth because if the cylinder was not firing right (detonating and discharging raw fuel) this would blow out the catalytic converter. The best way to see if it is a bent or broken valve is to buy a leak down tester which is part of a compression test. basically depending on specs you crank engine over grounding coils and see if all cylinders put out the same compression within 10psi of each other. it is usually around 160 -200 psi per cylinder. now to do a leak down test just leave pressure in and see rate of decreasing pressure and compare to other cylinders. if everything checks out i dont believe to be anything wrong with cylinder. Oh i forgot to ask any check engine lights on besides a cylinder 1 misfire P0301?

Very weird, a bad cat should not make it mis-fire, if it is just one cylinder it is mis-firing on, its worth checking the coil pack for that cylinder

I have a 2005 audi S4 B6. I just bought it with 37,000 mile on it. I just got it on the road and me and a buddy were beating on it. when driving hard the oil pressure light would go on but then turn back...


Sorry for the bad news i have for you, sounds like you dropped pressure to the top end which would mean that the Hydraulic lifters one or more have failed, could be that your intake or exhaust valve may made contact with the pistons at TDC. In any case oil pressure problems are known with that car, we found that one of the ckeck valves in the short block may cause that problem.
Solution would be new Motor at about $15000 with $4000 core unless warranty will cover. make sure you do not have an intake or exhaust system on the car cause they will not cover anything. Other option is to spend about $10000 to do a complete overhaul. First check your oil filter and see if you can see any metal shavings. But according to what you have written i would not longer drive or start the car. Sorry bud, i think your motor is done!!
