Hi Folks had my head under the bonnet for a bit today and down by the battery I've found an electrical connection not connected to anything and a pipe clearly broken off something.

The car seems to run fine but on the basis Nissan didn't put spare bits and jokes in could someone please tell me what they are.

the other end

 

Many thanks in advance

connector is probably of the AIV or EGR solenoid (in first picture you can see one of these solenoids at the right of your hand)

The hose should probably also connect to one of these solenoids...I guess AIV-soleoid, but looks a bit unclear as to where it originates from in the picture.

 

Both AIV and EGR are there for emission improvement purposes and won't really do any harm when not connected or disabled.

The engine will run fine without it.

brilliant thanks

always a worry when you find this sort of stuff

just realized I made a mistake...I had RHD/LHD mixed up.

Anyway.. in a RHD car, that connector should most likely be connected to the FPR-control solenoid (the solenoid at the right of your hand in 1st picture)

This solenoid can be bypassed without any issues, although in that case it's best to "loop" the fpr lines as you can see in this picture:

 

The hose could be from a number of things though...it could be from the FPR solenoid, the AIV system or the boost-sensor (if the boost dial on your dashboard doesn't work, then the hose is from this sensor)

 

if you start the engine and let it idle and there's no hissing noise from this hose, then it probably won't do much harm to leave it disconnected.

But you could check where the other end of the hose is connected to, to figure out what it is for and what it is supposed to be connected to.

Thanks again I'll check for hissing later and then probably panic :lol:
