hi guy,

i got a bunch of code since 2 week. I'm surprise i dont get a 30ff like every week, my wastegate are rattling as hell and the even stay open or doesnt close really well. I'm on the liste for vvt s2b2. But i have to prepare the car and it left 60 day before i receive them. when i push the car just a little bit i got the half engin chek engine and got low boost


so here are they:

2f6c exhaust fume flap, input signal
2e8e intelligent battery sensor communication
2caa lambda probe before catalyst, temperature
2ca6 lambda probe heating in front of catalytic converter, fonction
2c9c lambda probe heating in front of catalytic converter, input signal
0000 failure location not implemented
0000 failure location not implemented
2a12 dmtl diagnosis module tank leakage, magnetic valve, input signal

my explanation:

2f6c the can flapis unpluged so its normale

2e8e look like the sensor on the cable holding it is not working really well but i dont find a part number of the sensor ?!? I just find that one 61129123571
but its not the sensor

2caa+2ca6+2c9c probably have to change both o2 sensor so its 11787558055 and 11787558087

0000+0000 have no fck'n idea why i have those code

2a12 have no fck'n idea why i have that code


so M'I right with the part number and my diagnosis ?

could you explain the other code ?!

greats

car have a jb4 g4

Okay

#1 Get those o2 sensor codes fixed. If the engine doesn't know whats going on with the AFRs (which the o2 sensors do) it's going to be very grumpy, and it could spit out your CEL when you try to get on it.

0000/0000 isn't a real code, so totally useless

2a12 relates to (after some googling, lol) the Evap system leak checking pump. They call it a DMTL pump. The one thread I found on this, buddy had a bunch of other codes with it as well. If you can find the DMTL pump, maybe there's something you can clean and see if the error goes away.

I was thinking that there is only one o2 sensor by down pipe but there is 2 by dp !

There's actually 4 o2 sensors in the N54. 2 pre cat (1 for each bank of 3 cylinders) then 2 post cat (again, 1 for each bank)

You will want to replace both of the pre cat sensors if thats what the issue is.

OK Thanks, could we know wich back it is with the code ?

All o2 sensor are the sa me or not ?
