Does anyone know how long does it take and how hard is it to get to the turbos of the Allroad. I have heard you have to remove/lower the whole engine. Thats a first for me, always had turbo cars where the turbo is very easy to remove.

Re: Turbo repair and replacement
Yep, you've heard right - the easiest way is to actually remove the engine from the car. Because it's a biturbo V6, the turbos are snugged up under the heads, and are virtually inaccessible from above or below without significant disassembly.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

Get it back to whomever did the job. Or maybe take it to someone who knows what they're doing. Turbo line is obviously leaking. If it's not cranking even with a jump you may have seized he engine. 2.7's are not cheap!
the firing order for 2004 Audi Allroad Quattro 2.7 liter DOHC V-6 Turbo (BEL) is :--------------------------------------------
1-4-3-6-2-5. ------------- 321 on left bank side and 654 on right bank side. ---------------------------This will help.Thanks.
I will just make a suggestion, I am not familiar with your system. The chamber that routes the exhaust gas should have a diverter valve or plate in it. There should be a type of operating valve plunger similar to the EGR which would open to reroute the exhaust back into the turbo.
I am thinking the valve is stuck open(carboned up) or burned through so that it no longer controls the boost. Otherwise you would be looking at electronic controls that may need to be reflashed(reprogrammed) back to factory specs.
If you look on the internet, you may be able to find these Turbo parts and valves at least advertised for sale with photos that may be useful. Then you would know if you can attempt to clean or replace the defective area.
Remember, what is heard as turbocharger noise may not be caused by a noisy
turbocharger. Before replacing a turbocharger perform the following diagnosis.
A. If a loud whine or whistle is heard during acceleration
and increases or decreases with rpm and load. This condition is most often
the result of a loose clamp/hose at the turbocharger compressor outlet, charge
air cooler inlet, outlet or at the intake manifold.
1. With the engine running at idle and the transmission
in Park or Neutral with the parking brake set, feel for boost air escaping
at each connection between the turbocharger compressor outlet and intake
manifold. For limited access areas, spray soapy water on those connectors
and look for bubbles.
2. Check the exhaust manifold and exhaust system for
hi what was the code (p 0244)sounds like you need to replace the the turbo wastegate valve .sounds to me like its overboosting as if the charge from the turbo gets too hot the engine will misfire thus causing damage to engine ,the waste gate valve is there to prevent over pressurisation
