Engine oil in charge air coolers
Transaction No.: 2050222/4
Customer statement / workshop findings
Liquid glugging noise evident from engine charge air intake system - Excessive oil discovered in charge air coolers. Low engine oil level may be
displayed in the driver information panel
Technical background
A specific level of oil residue is expected in a charge air cooler. Currently the level of oil being seen in some Bentayga charge air coolers is excessive.
Investigations are taking place to identify the cause
Production change
TBA
Measure
Bentley Engineering are investigating this phenomena
Any oil found in the charge coolers should be drained off, any remaining oil residue should be cleaned from the charge coolers and hoses, the vehicle
should then be returned to the customer.
Should misfires be evident within the engine control module/s after the previous process has been conducted and a DISS query is
raised please also ensure the poor engine running complaints (Misfires) TPI 2051187 is conducted. Please also refer to Service
Operations Newsletter - Issue 19 – April 2017 Snap-On BK5600 Borescope – Best practice guide, refer to the Bentley Hub for this
documents
If after a road test of the vehicle the ‘Engine management light’ illuminates, check the fault memory of both engine control modules
for either of the following DTC’s;
•
Address 11-Engine Control Module 2
“P2A0B00: Manifold Absolute Pressure Sensor "B" Circuit Range/Performance”
Or
•
Address 01-Engine Control Module 1
“P010600: Manifold Absolute Pressure or Bar. Pressure Sensor Circuit Range/Performance”
If either of the DTC’s is stored, remove the relevant MAP sensor (G429 or G71) and check for oil contamination in the sensor. If found to be
contaminated replace the affected MAP sensor.
