Symptom : 603300 No Start
Content : Issue:
Non start, poor idle, rough running, P0089-7A and or P1169-00 logged.
Cause:
Potential water in fuel tank. A small number of service replacement parts have been returned to engineering for inspection and in each case the breather / vent line has been blocked with water / mud / dirt. A blocked breather / vent line would cause the fuel tank to vent via the fuel cap. Engineering testing has highlighted evidence to suggest water is collecting inside the fuel cap, (via the fuel cap lock barrel), and is then drawn into the fuel tank during the breather / venting process.
Action:
This will depend on the severity of the contamination, the quality of the engine running / performance and whether or not any DTC are logged and what they relate to.
Please follow the steps in the attached pdf doc to determine which course of action to take.
NOTE)
Any vehicle presented to the dealership with DTC P0089 and P1169 must have the fuel pump and rail replaced.
DTC other than P0089 and P1169 are not so important in contamination cases and do not necessarily mean that parts should be replaced. Please follow normal diagnosis procedures for other logged DTC. Please submit an ePQR for reference.
New fuel tank with updated breather location introduced for Defender 90 at Vin 760582. Defender 110 / 130 at Vin 760304. See attached pdf.
Curiously I've not been able to find this on GTR so I can't vouch for its veracity. Although there is a Special Service Message for what to do if contamination is suspected.
