P0471, P2178 and P2187 errors for Audi Q3 1.5 TFSI

[Tawfik]

Hello,

I’m new in the forum. I need your help please.
I replaced the engine of my Audi Q3 1.5tfsi two months ago. After replacement I got immediately the check engine error and the following codes:
37320 - Capteur de pression 1 des gaz d'échappt (G450) Signal implausible


P0471 00 [0363--


Intermittent - Non Confirmé - Testé depuis RaZ mémoire


2822 - Banc1


P2178 00 [0391 - Syst. de dosage du carburant trop riche à partir du ralenti


Non Confirmé - Testé depuis Raz mémoire


4105 - Banc1


P2187 00 [101] - Syst de dosage du carburant trop pauvre au ralenti


Non Confirmé - Testé depuis Räz mémoire

I already went to Audi and they replaced the G450 sensor but still getting the same errors/ check engine.

Is any one have an idea about this ?

Here bellow the auto-scan I did yesterday:

Removed.  Data from a clone/pirate copy of VCDS is not acceptable in Ross-Tech's forum.

First and foremost the Forum Rules dictate that you Scan your vehicle using the "ENGLISH" version of Vcds. Not a Translation - Will not be accepted !

You are using the FRENCH version ? Keep that on your PC.

Now download the English Version from this link https://www.ross-tech.com/vcds/download/current.php

@Uwe

Perhaps this can be "Simplified" - May or may not be simple to implement - I dont know !


Could the English version not be piggy banked on to the other language versions ?


For example, when our friend @Tawfik downloads the French Version he gets the English version sneaked up his shirt for free ?

I am assuming he has a Legit VCDS

Hi Sheldon,

Thanks a lot for your quick answer. I will download the English version and do a complet scan in English.
