Possible HP Fuel Pump issue with CASA/CATA engines
Whilst visiting my local Third Party VW Specialist yesterday, They informed that they have had two CASA V6 Tdi engines with catastrophic High Pressure Common Rail Pump failures in the past two weeks.
Both engines had done over 200,000 km and in both cases the HPFP had disintegrated resulting in metal fragments and filings being forced through the injectors, This resulted in total loss of not only the pump ( about AU$ 1,200 ) but also the injectors ( about AU$ 600 each ) resulting in a repair bill of over AU$5,000 plus labour.
The vehicles involved were apparently stock standard and had not be subjected to any apparent abuse. They don't have enough information as to the root cause but suggested that it may be related to fuel quality. They also stated that I may be interested in looking at Diesel Fuel treatments as a form of insurance. Understanding that they DON'T sell such products, and were only thinking out loud as to what may be useful.
At this stage the failure of two engines may be simply bad luck, which I sincerley hope is the case. I think it is something I will be following closely to see what more information I can find.
