Are these two issues inter-linked?

Post by rtd » Sun Jul 19, 2009 10:36 pm

Did Vagcom this morning which threw up the following fault code;

1 Fault Found:
16622 - Manifold Pressure / Boost Sensor (G31): Signal too High
P0238 - 35-10 - - - Intermittent
Readiness: 0000 0000

then ran the 032 feature and got the following readings;

Group 032: Lambda Control (Mixture Adaptation)

1.9 % Adaptation (Idle) Bank 1 Sensor 1
-17.2 % Adaptation (Partial) Bank 1 Sensor 1
2.1 % Adaptation (Idle) Bank 2 Sensor 1
-16.4 % Adaptation (Partial) Bank 2 Sensor 1

can't believe that i may have another boost leak having had one fixed by doug a week a go. could it be that i am getting the above fault code as a result of the suspected boost leak?

I would clear the DTC, and then see if it re-appears as it says intermittent

Although yeh does seem you have a boost leak.
