Touareg 7P, P214900, Need Help

[Roberto 68]

i urgently need your help.
VW Touarg 7P, MY 2013, engine code: CRCA, 180 kW.
Every time I press Kickdown the car goes into emergency mode and shows:


P214900 Fuel Injector Group "B" Supply Voltage Circuit Open


It only happens during Kickdown!
I have already replaced all 6 injectors and checked all cables from injectors to ECU, without success.
all wires are OK. Tested from ECU to injector.
ECU removed, is dry inside and looks good. All resistors and transistors tested as far as possible. All 6 outputs from the injector have the same capacity.


If any of you have had this problem before or can give you a repair tip here?


Please help.

So either software at fault or weird chaffing

Can you get car on rolling road or on somebody else’s ramp

try kick down then, in therory the engine “wont move” so if chaffed
stop the fault.

if still faulty on rolling road, then implies from your DK stats you might have pile of DK thanks
