Logged this - Fuel pressure is well off. Could the Fuel filter cause this or is it definitely the pump?

[johnhol78]

Ever changed your cam follower?

Yep when the internals were put in.

Sorry Ed didn't see your post.

Will order a cam follower today - is the sensor just called Fuel Pressure sensor? Part num?

Thanks

etka calls it Thrust Sensor and the latest part number is 06E906051K.

DIY job or garage only?

DIY job or garage only?

It's easily a DIY job with the correct size spanner.
I suggest first you relieve the pressure in the fuel rail by bleeding it using the Schrader bleed valve on the hpfp.

Awesome thanks....will try this first. Then if no improvement tackle the nightmare of taking the fuel pump off (banjo fitting) and checking the cam follower.

You should be aware that the sensor is around £48 from the dealers so IMO you should look at the cam follower and cam first to minimise unnecessary spending.

Sorry for the questions....but what does checking the cam entail? Cam follower I'm fine with though the cam?? not so sure.

Just run your fingernail on the cam lobe surface after you remove the follower.
If the follower is in good condition it should be smooth. If the follower is very worn down but not punched through then it's worth checking the cam for smoothness as a heavy scratched lobe can cause increased wear on the cam follower.
