Lambda replaced, N75 issues?

Post by **teambeer** » Mon Mar 05, 2007 3:16 pm

Well got around to replacing the passanger side lambda the other day(which was fun)
But still only getting a maximum of 63% on the N75 duty cycle.It's much improved over the previous 10.2% and the car feels much better but this still sounds a little low to me, any ideas?

Where did you get the percentage values from?

Can you log MAF flow and boost @ WOT in 3rd through the rev range

003 and 115 on VAG-COM

Those values where from group 114 as far as I remember

Will get some logs from the Maf as soon as I can.

Ok just got some more logs, throttle position is on the x axis and airflow peaks at 121.25

Hmm just had another check and it's also throw up:
17536 - Fuel Trim; Bank 1 (Mult): System too Lean
P1128 - 35-00 - -
So looks like the Maf is faulty?
