@Stevey Y hoping you maybe able to help please

Took off air intake pipe today and where it connects to EGR/manifold/turbo unit I have seen some oil and debris/dirt build up. is this normal from the breather or should I be concerned? Air filter is in good shape and clean. 2015 Audi a6 c7 2.0 TDI with CNHA engine. thanks

Hi I’ve just done a static regen on my 2015 A6 C7 2.0 TDI following which without issue. Showing some strange figures though. On completion it showed: - particle filter soot mass calculated 1.95g - particle filter soot mass actual -7.27g (negative reading) - oil ash volume 0.11L Should the actual mass value be a negative or minus figure?

So I bought my 2015 A6 C7 in January 2022 with 50,000 miles. Bought it from a reputable main dealer (not Audi) and since purchase I’ve had the following issues: windscreen replaced/leaking, considerable ingress drivers upper right of screen into headlining - February 2022 New battery - April 2022 New throttle - February 2022 Dual mass flywheel/clutch failure and replacement - February 2022 Previously reported excessive vibration and gearstick shaking through manual gearbox (mounts all checked) - 3rd/4th/5th gear most obvious - august 2022 Jumped timing and timing belt water pump replaced - September 2022 Brake issues - sensor cables replaced. Originally replaced rear pads April 2022 but continued and ended up replacing brake sensor cables. Engine/gearbox mount inspection - august 2022 Gearbox/engine seals repaired/replaced - oil leak on top of gearbox - cleaned after repair - August 2023 Intercooler pipework resecured? - August 2023 Had the car back 1 week before it appeared to be running rough again and was taken back in on 14th august 2023 for 6 weeks. Currents issues: Turbo exhaust gas leaks under actuator with carbon deposits visible On occasion blowing smoke on acceleration Oil leak around cylinder head cover/pcv Can consume coolant regularly Still vibration in gearstick and squeaking when gear changing Vibration/juddering when driving - obvious on motorway in 5th/6th gear at 60mph plus car is going into Audi now on Tuesday 17th October for diagnostics so will be interested to see what they find! needs resolving asap. turbo issues:

So I have nothing in the ashtray, centra cup holder or arm rest, have driven with glove box empty too and annoying noise still there - just in case anyone states the obvious and thinks I’m just stupid haha! All door pockets are empty as are the two trays under the seats. I’ve literally emptied everything out the car as well as removed the whole centre console including CD player and radio control and arm rest, mmi controls, gearstick etc and still cannot find this…. when I steer there and annoying noise that sounds like it’s coming from centre console or right behind the dash which sounds like a marble rolling side to side depending on which way I steer! For the life of me I can’t !Removed! find it. any help or suggestions…..I can’t think what else I can physically remove from the car to try and find it and nothing obvious ever been dropped into the vents
