What Is Suction Control Valve (SCV) Failure.

SCV Suction Control Valve L200

What Is A Suction Control Valve?

The Suction Control Valve or SCV is responsible for the control of fuel pressure inside common rail engines. It allows only the required amount of fuel to be pumped through the system.
The SCV is a wear item, that is a good part to cross off your list of things to do – just like a cam / timing belt.

How Do I know If My SCV Has Failed?

The suction control valve is often overlooked when you are having issues with your vehicle.
SCVs can quickly become affected by contaminated fuel and dirt which in turn can cause a vehicles Electronic Control Unit (ECU) to cause surging and other symptoms, such as ‘limp mode’.

Milner Off Road Ltd stock Genuine Suction Control Valves for the relevant models .

Is There Anything I Need To Know About My New SCV?

After fitting a new SCV.  You may need to a  re-calibrate / relearn.
There is a procedure for it in the manual.

The ECU learns the relation between the suction control valve, of the supply pump drive current and the fuel injection volume.

The learning value is calculated from the suction control valve drive current and the rail pressure sensor output voltage.

You should run the relearn when the engine is idling, any one with a decent plugin diagnostic computer should be able to do it for you.

Nissan Navara Sagging Rear Suspension Issues.

Nissan Navara Rear Suspension Issues


Nissan Navara Rear Suspension Issues.

The model in question is the Navara NP300 2015 onward.

The vehicle itself gets a 4.5 out of 5 stars by AutoExpress, reporting  ”Small bumps are ironed out far more effectively and the floating feeling over sudden undulations is much better suppressed.”
However, while it brings some benefits when unladen, it has been criticised for struggling to cope with anything approaching its claimed load weight of 1 tonne. Further more Nissan state the NP300 has a 3.5 tonne towing capacity.

Despite the claimed stats, opinions from owners are coming in that their Nissan’s are ”struggling” with loads well under the claimed payload. Unmanageable steering and sagging springs are just a few to mention.
Vehicles that are used for work or tow large trailers are proving that the standard rear suspension is much too soft.

Here at Milner’s we developed a kit to abolish the NP300’s flaws / poor rear suspension characteristics.

The Milner kit will restore the vehicle to a more usable ride height when loaded/towing without compromising comfort when empty.

Kit Comprises of:
2 x Upgraded Coil Springs
2 x Heavy Duty Shock Absorbers

(The shock absorbers must be used to overcome the effects of the stronger spring.)
