2009 Audi Q7 4L 3.0 TDI cranks but doesn't start
Recently picked up Q7 3.0TDI with 75k kms on the clock. It has an ABS and ESP error that piped up soon after tire rotation and alignment work being done.
Saturday last week,, while I was overtaking at about 80/90kms speed the car just died. It cranks but doesn't start ever since.
I don't have a VAGCOM but I did scan using Launch X431. Below are the error codes. The scan says there are 8 errors in total
008213 - intake manifold flap position sensor bank 1
000135 - fuel rail / system preasure
05405 - ( 24, F1, 15, 1D) please refer to relevant tech manual
001393 - break switch (F)
01423 - sensor for leaking lateral acc.-G200
01487 - system function test - value of resistance too great
01486 - system function test activated
00778 - steering angle sender G85
from google, I understand that none of these should have lead to the car stalling while driving.
have any of you experienced similar issues, should I be checking the crank position sensor. I see that the RPM needle move while cranking. Does this me an that the CP sensor is working.

Have done the following
1) removed the bank 1 and 2 to clean and re fix the swirl flaps. Bank 1 has play so am using a rebuild kit to fix both the banks.
2) cleaning the intake manifold, EGR and throttle body
Hope the clean and refit plus the siwrl flap kits fix the issues.

Open the engine cover
look for the fuel mechanical high pressure fuel pump
there is a fuel metering sensor on its right side
remove the sensor. Check for metal particles. If found then that is the reason the car is not starting.
you will see error codes for fuel pressure
