VCDS Serial number
C?ID=342531
got these two codes but no eml light on.....
are they related ?
will the particulate trap bank 1 error 19226 trigger exhaust pressure sensor 1 error 20169 ?
what would be the best way to determine using VCDS and values expected on a CRKB engine May 2015 ?
bit of a copy and paste below from log

Hi!
1) Post a full autoscan, in Code tags
2) Check measured value of exhaust pressure sensor with engine not running (just ignition on), engine idling, and @ 3000-3500 rpm

Open the engine ECU, select the function for Measuring Blocks (or Advanced Measuring if your controller is UDS) and choose the appropriate measuerment value

You have UDS based ECU, so You will have MVB grayed out. Use Advanced measured values instead. Use search window in this mode, type in "exhaust", for example

ok thankyou....
will have a look and see what values I get...
the other thing I did notice was it does not rev past 2000 rpm when engine is running and in neutral....is this a safety thing with Audi ?

got two readings....
at ignition on

and at idle
Code:

An offset of nearly 200 mbar seems really high for a differential pressure sensor, doesn't it?

Is the line contaminated to PSI sensor with negative deviation?

mmm....what is PSI and what exactly do you mean by line contamination with negative deviation ?
as posted earlier....its variable readings every time I tried a read

2 exact same coded sensors sit beside each other in a silver heat bag
but looks untouched and unmolested ......so
can I swap them round and see what happens ?
I am inclined just to replace both though
reading the codes with no eml ....just pending emissions codes and very random as when it throws the fault but never with an eml or any lack of driveability...
the 2 sensors are 04L906051 and have just noticed a single further towards the front of engine coded 04L906051 B aswell
