Technical product information
Water leaking from the mechanical water pump - Low coolant level warning displayed - W12 TSI
Transaction No.: 2065919/3
Customer statement / workshop findings
Workshop findings:
•
Coolant leaking from the mechanical coolant pump
Or
•
Coolant witness mark on the mechanical coolant pump although coolant is not leaking/dripping from the pump
Or
•
Low coolant level warning displayed
Technical background
The operative MUST ensure the instructions within the Measure section are followed, the instructions differ slightly depending on the part
number of the mechanical coolant pump (B or C suffix)
NOTE: Warranty payments will not be authorised unless the mechanical coolant pump has been authorised for replacement via a
technical DISS query
Production change
The following part numbers are affected
•
07P 121 008B
•
07P 121 008C
Measure
1) On receipt of the vehicle - Take a photograph of the coolant level within the coolant reservoir
•
Using ODIS check to confirm that no DTC’s are evident relating to low coolant issues - Save the current ODIS log
•
Take a photo of any coolant related warnings which are evident within the DIP
•
Take a photo of any suspected coolant leaks
2) Referring to Rep.Gr 19 - Pressure test the coolant system to confirm if a coolant leak is evident from the mechanical coolant pump
VERY IMPORTANT: In the event the mechanical coolant pump is leaking/dripping as a result of conducting the coolant pressure
test - Record a clear video of the leak (whilst carrying out the pressure test)
Refer to the video located within the Bentley Hub reference TPI 2065919/- this video shows an example of a coolant pump with
no leak although there is a small coolant witness mark evident (Figure 1) in this scenario the coolant witness mark should be
cleaned off (using a suitable cleaning agent) to the condition shown in Figure 2
INTERNAL
Figure 1
Figure 2
3) Conduct a road test
•
On return conduct a visual check to confirm the leak is no longer evident
•
Should no leak be evident, no further action is required
•
In the event there is no visible coolant leaks from the mechanical coolant pump and the coolant level is to specification as per Rep.Gr 10 DO NOT replace the mechanical coolant pump (No further action is required)
However
•
If a visible coolant leak is evident when conducting the pressure test the operative should continue with the remaining instructions to
completion
4) Check to confirm the part number of the mechanical coolant pump
HINT: If 07P 121 008B is fitted - Continue the repair as required and replace the mechanical coolant pump as per Rep.Gr 19
INTERNAL
NOTE: For this scenario only (07P 121 008B fitted) No further feedback or confirmation is required via DISS
Ensure all procedures within the Repair manual are followed including any alignments/calibrations which are required (Depending
on vehicle specification)
Or
If 07P 121 008C is fitted the operative should conduct the remaining instructions to completion
•
The operative must raise a technical DISS query or respond via an already open DISS query ensuring the following is attached to the DISS
query:
•
Clear photo of the coolant level
•
Clear photo of the mechanical coolant pump part number 07P 121 008C (Figure 3)
•
Current ODIS log
NOTE: the photo shown in Figure 3 is of a C level coolant pump removed from the vehicle for photographic purposes only a borescope may have
to be used for photos of the coolant pump fitted
Figure 3
•
Record a clear video of the coolant leak whilst carrying out the pressure test
•
Request permission to replace the mechanical coolant pump 07P 121 008C due to a leak from the mechanical coolant pump whilst
conducting the pressure test
5) Once permission has been given via the technical DISS query, replace the mechanical coolant pump - Refer to Rep.Gr 19
Ensure all procedures within the Repair manual are followed including any alignments/calibrations which are required (Dependi ng

on vehicle specification)
NOTE: Do not discard the mechanical coolant pump (07P 121 008C) as it may be requested for analysis
