Measure
•

DTC’s P008700 and/or P008800 are evident within the master and/or slave engine control modules. The DTC’s are related to fuel
vaporisation within the fuel delivery rails due to the winter fuel blend

NOTE: This issue occurs soon after the engine has been started (engine close to normal operating temperature or at normal
operating temperature) or at idle (typically within 30 seconds after starting the engine) the issue is unlikely to occur on first
engine start of the day as the issue typically occurs after engine restart (up to 30 minutes)
•

Immediate key off (abrupt stop) could cause high fuel pressure retention which could cause the issue on the next restart (restart within 30
minutes)

In the event the afore mentioned symptoms are evident please conduct the following:
•

Clear the applicable DTC’s and ask the operative to attempt to reproduce the reported issue. In the event that the issue cannot be

reproduced the operative MUST top up with fresh summer fuel (if available) and clear the applicable DTC’s
Fuel Vapour Lock

After a long idle (typically after 20 minutes or long periods in city traffic (very low speed)

•

Exacerbated by winter fuel blends combined with exposure between 5 Degrees Celsius (41 Degrees Fahrenheit) and 20 Degrees Celsius
(68 Degrees Fahrenheit) ambient temperatures

•

Normal engine running temperature

In the event the afore mentioned symptoms are evident please conduct the following:
•

Clear the applicable DTC’s and ask the operative to attempt to reproduce the reported issue. In the event that the issue cannot be
reproduced the operative MUST top up with fresh summer fuel (if available) and clear the applicable DTC’s
