Thanks to our program member from: Woodbridge, ON
Vehicle: 2011 GMC Savana 6.6L Duramax
Condition:  Cannot do the Diesel Particulate Filter regeneration, has code P24A0.
Agent recommendation: Check TSB and also make sure that, after the vehicle is left overnight, the 4 temperature sensors (2 for the exhaust and 2 for the engine) are within 3 degrees each other.
Solution: Technician has checked the TSB and read the temperature sensors with scan tool and found 1 exhaust temperature sensor was off by 10 degrees. Replaced the sensor and was able to do regeneration.

Thanks to our program member from: Scarborough, ON
Vehicle: 2011 BMW 323i automatic transmission
Condition: Engine oil leak from the engine oil pan. The technician requested the labour operation time for the procedure.
Agent recommendation: Have checked many places and in the available online service information for this vehicle, there were no labour operation times.
Solution: Always check with us first for labour operation time availability but be aware of some limited information due to their service information structure.
