Hi,
For anyone with the 3.0L TDI engine. 
1. If you use a monitoring tool for the DPF have you ever noticed a sudden jump (>15%) in soot% for the calculated soot mass?

 VCDS STFT and LTFT not updatingHi,

In blocks 001, 032 and 033 the lambda % will never change and stays on 0%. If I introduce a lean condition (cam cover...Last edited by sambb; 13-04-2018, 05:37 PM.

 9N3 GTI Downpipe and Lambda SensorsHi all,
 
 VAG-COM tells me the CEL I have is due to error "16414 - Oxygen (Lambda) Sensor B1 S1: Heating Circuit: Malfunction (Open Circuit?) P0030" which from what I've read here and elsewhere is the pre-cat sensor. Before I race off and order one, I just wanted to check that...
