On the way home tonight, the car blinked the glow plug light and advised 'workshop' in the DIS. I used my OBDeleven Pro to clear the code, which came back up reasonably quickly. When we stopped at the grocery store, I cleared the code once more. Hasn't reappeared... yet. So ~100 km.
From the Rosstech wiki:
Same thread mentions two TSB's to be aware of, which I'll keep in mind when we take the car into VW for the #dieselgate settlement repairs.
VW TPI 2012601
VW TPI 2026831
Anyone know off hand what those TSB's relate to and/or have handy some links I can peruse?
My hunch is that this code is related to a previously posted issue of mice chewing through the rear 02 sensor wiring between the NOx storage cat and the H2S cat. (http://forums.tdiclub.com/showthread.php?t=477765, and no not fixed yet... been busy with the farm )
New codes:
P2452 - Diesel Particulate Filter Differential Pressure Sensor static
P0135 - O2 Sensor Heater Circ.,Bank1-Sensor1 Malfunction Lower limit not static
P0141 - O2 Sensor Heater Circ.,Bank1-Sensor2 Malfunction Lower limit not static
Old codes:
P0136: Oxygen O2 Sensor Circuit Low Voltage (Bank 1, Sensor 2)
P2271: O2 Sensor Signal Stuck Rich Bank 1 Sensor 2
But I'm new to diesels in general so I'm probably off base lol.
From the Rosstech wiki:
Got home, did some digging. This fine forum provided me a good nugget of information as a starting point, essentially suggesting to clean the contacts first as advised in the Ross-Tech wiki above:wiki.ross-tech.com said:18000/P1592/005522 - Altitude Sensor / Boost Pressure Sensor: Implausible Correlation
Possible Symptoms
Malfunction Indicator Light (MIL) active
Limp Mode active
Possible Causes
Ground Spots corroded
Wiring from/to Boost Pressure Sensor (G31) faulty
Boost Pressure Sensor (G31) faulty
Possible Solutions
Check/Clean Ground Spots
Check/Replace Wiring from/to Boost Pressure Sensor (G31)
Check/Replace Boost Pressure Sensor (G31)
Special Notes
When found in 2.0l TDI-PPD, check for matching TSB/TPI (i.e. VW TPI 2012601 and/or 2026831).
Check/Clean Ground Spots
Check/Replace Wiring Harness for Boost Pressure Sensor (G31) and Intake Air Temperature Sensor (G42)
Check/Update Engine Control Module Software/Firmware
