2015 passat need help with P2102 & P3243 and fuse location for Throttle Valve Module J338 !

Well other day i had GP Light started flashing on my way to home, but there was no noticeable loss of power. however when i came home, turned off the car and from that day and onward engine started shaking while turning off the car. so did the VCDS Scan and it showed, let me paste it from fault portion of Scan:

I am assuming you are looking for information on the J338 regulating flap?

It is the one going into the intake/intercooler assembly.

The part number is 04L-128-063-P

It is below the adapter, which is against the EGR valve, which is what is bolted directly to the intake.

It could be bad, it could be severely gunked up although I doubt it, or you could have a wiring harness problem. I have not had to mess with this on a CVCA engine yet, so I don't have any other tips for you, sorry.

thank you Oilhammer!, I ordered it..

my initial thought was battery might have been low so changed battery and "Cleared codes". ran scan again but code has not appeared again. but funny thing is engine still shaking while turning off the car.. one can think valve might have stuck open. i have electrical diagram from ERWIN (nearly 600 pages pdf) but don't know how to read, as i was trying to find fuse for that valve, if somebody can help to read i would appreciate it!.-thanks

changed J338 regulating flap aka Throttle Body Actuator. Car does not shake anymore while shutting down. Flap was stuck open, although it was very clean. it was done by TDI mobile mechanic, also member here known by his username " FredSo ".

Glad you got it fixed, and thanks for following up, as these threads are most helpful in the future for people searching if an actual resolution was posted.
