17840 - Secondary Air Injection Solenoid Valve (N112)
P1432 - 004 - Open Circuit

How can I decipher which 'bank' the code is for?

I checked the fuse (for bank 1) and swapped the relays for each sai pump, no change.

Anyone dealt with this? Could it be the pumps, the hoses, or the actual 'combi' valve itself that may be the culprit?

If it's the combi valve, good part # to replace? Same as any other VW/Audi?


Thank you

 

Anyone? Could it be the valve itself?

 

Well.. researching the 'N112' appears to be this electronic type solenoid/valve for bank 1.

Secondary air inlet valves N112 and N320 are two 3/2-way solenoid valves and are switched by the engine control units. They activate the combi valves via a vacuum line.

I believe it is part# 037906283C

Does anyone know the location of this part on the Bentley engine to replace?

 

@Johnny Hotspur GT Hey Johnny hope you are well. Are you able to assist with the location of this little N112 valve? Thank you!!
