    3.0TDi Lockup on startup when warm, no smoke at all though

    Hey guys, My 3.0TDi (BMK engine) has fairly frequent lockup on cranking when the engine is warm, roughly 5 to 10 minutes after switching off. Like when one pops into the shops and comes back out. It usually cranks, there's a "click" when it jams/holds, then resumes cranking and fires fine...

    What part is this? a6 tdi 3.0 quattro

    I believe it's the coolant valves for the HVAC system. They do go faulty and aren't too difficult to replace. There's also a video on youtube of a guy cleaning the valve plugs on one to get it working again, which can be done without removing the entire valve body:

    servotronic steering relay

    Here's a post from a guy who added a resistor to the circuit of his servotronic valve on his C6: https://www.audiworld.com/forums/a6-s6-c6-platform-discussion-58/adding-positive-caster-adjusting-servotronic-steering-force-2606518/ This suggests that the setting can't be adjusted in the module...

    servotronic steering relay

    I'm not 100% if the 2011 is the same, but on my 2006 there is no relay. The servotronic solenoid on the rack is driven directly from the central electronics module. I know this because I had to repair some wiring to it to get my servotronic back. I can try check on wiring diagrams later for the...

    PDC and Reverse Camera decisions!

    Hey, thanks for the reply, Ya, I have all those different PDC module part number listings which list their different attributes. So basically you're saying, if I want to install only rear sensors for now, I can get a module which supports 8 sensors and reverse camera and just code it for only...

    PDC and Reverse Camera decisions!

    Hi Guys, So my 2006 A6 Avant doesn't have PDC or reverse camera, which is a pity since my previous 2004 B6 Avant at least had PDC as standard! I have MMI 2G high. So I'd like to install either PDC or a reverse camera. But to help me decide which route to follow, can anyone answer the following...

    3.0 TDi engine removal

    Hi Christoph, The right of the engine is the right as it's driving forward. To replace the right side top tensioner you don't need to remove the turbo, to replace the left side top tensioner you need to remove the turbo apparently. By your explanation of replacing the left when looking at the...

    3.0 TDi engine removal

    Just thought I'd follow up for anyone who's reading these threads at any point. I replaced my top right tensioner and instantly the "death rattle" on startup is gone. So as per the Audi TSP in the "Phew! that's a relief" thread, the old tensioners are de-tensioned under reverse cam pressure when...

    3.0 TDi engine removal

    Hey Mike, Thanks for the detailed reply. I'm happy that everything went well for you. I've ordered a new top right tensioner from my local Audi dealer, who gave me a decent discount so I don't feel too bad not getting the Febi one. It's difficult to get the Febi stuff here in South Africa...

    3.0TDI Tensioner Replacement

    Hey Guys, I'm going to do my right hand side tensioner. But does anyone know if the left side can also be done with the engine in the car? Thanks

    3.0 TDi engine removal

    Hey MikesA4, So how did it go? I have the 2 second rattle on startup on my A6's BMK engine. I'm trying to decide if it's tensioner or lifters, but I'm leaning towards tensioner on the right hand side. I'm going to try replacing that one and see if it solves it. What were your symptoms? Oh, and...

    Do these IQ values mean I need to change injectors?

    Hi Guys, Vehicle: 2004 B6 A4 1.9 TDi, AVF Engine So I've been having the PD idle shake symptom, which seems to be fairly common when doing searches. Nobody has any definitive answers, but there are some common causes presented, such as worn cam, worn DMF, worn injectors, injection timing out...
