WARNING

Before fitting a new high-pressure pipe, lightly lubricate the nut threads with the oil from the applicator provided in the new parts kit.

Be careful not to allow oil into the high-pressure pipe.

Do not lubricate high-pressure pipes supplied without an applicator, as these high-pressure pipes are self-lubricating.

V - REPLACING THE HIGH PRESSURE PUMP

Note: For VDiag numbers before Vdiag 48, it is essential to reprogram the injection computer. If the computer is not reprogrammed, do not apply the procedure described below but prime the circuit using the manual priming pump.

Note: Never start the engine until the pump has been reprimed.

Also comply with the operation instructions provided to prevent the high pressure pump from being damaged internally, due to its running empty and with no diesel lubrication.

Note: The starting phase can last up to 20 seconds.
