Hi guys,

I own a 2001 patrol Y61 3.0 d.

Bosch just replaced the diesel pump.

Since then the turbo wont kick in.

We checked the switch that supplies the vacuum to the turbo. It seems that there is no current to the switch.

Can anyone please tell me what to look for. Can it be the ECU, where does the electric pulse or current that switches this switch originate from. What can cause be the possible cause. Any ideas please.

Any assistance will be appreciated.
