hello,i own an audi TT 225hp which has now a muggianu turbo kit for 400+ hp
the old internalls are gone,i use now forged pistons
my problem seems to be n112 code error 17830
can anyone help?

 

If you have a 400hp car and you think the pistons are the weak point of the engine, i hope you didnt build it. The stock pistons have been shown to go to 600+hp. The rods on the other hand have been known to play peek-a-boo at a little 300-350ftlbs of torque. (depending on how low in the rpm band and torque spikes.)

the n112 is the secondary air pump, its either gone bad or has been disabled in some way. Without the secondary air pump your car does not have an adaptaion in place. So you might wanna get that fixed.

17830 / P1422 = secondary (AIR) valve/solenoid - short to pos+ faults could be wiring or AIR valve/solenoid
