MOT Failure Spraying fuel. TD6

spitfire · Dec 18, 2012

Hi, Had a call from the garage testing the car to say it is spraying fuel over the back axle, not managed to get over there to look at the offending part. Had a look at Rave and from the testers description it sounds like the bi metallic valve. Has anyone ever changed this item, is it a common failure part. Many Thanks Ian

If it is more to the O/S of the axle then I would hazard a guess at the FBH pump

if its over the back axle could be either the pipe from the lift pump to the inline fuel pump or the fuel tank return from the injection rail.

Thanks for the info, managed to get over to the testers today. It is the additional (in Line) fuel pump which has failed, the mechanic tried to prise off the rubber fuel pipe and the pump literally fell to bits it was so corroded, good job it didn't fail whizzing down the motorway. Well spotted by the tester, and to think they were considering 2 year gaps between tests. My car is a 2003 model and I suggest if your vehicle is as old, check the pump it's a swine to get to but seems very prone to corrosion. The car also failed on the rear hub bushes, both sides, £30 from the stealer but hundreds to fit and with a tyre I think its going to be a £1000 MOT.

Hope the kids don't want anything for Christmas.

Yes Type A is the one. Have ordered one off the bay not quite the same but £100 cheaper. Garage took it out and bypassed the pump to get it off the ramp. Ran fine without it, is it really necessary?

Woah Tiger !!!

Block it up DO NOT simply join pipes back together

Thats the FBH Auxillary heater metered fuel pump

Your FBH under the N/S/F inner wing will now have the possibility to flood once fuel syphons to it (as you have no in-line pump connected) and be a fire risk if and when the FBH attempts to "fire-up"

The FBH pump has no bearing on the vehicle running

Blimey i've heard of these heaters but didn't realise i had one fitted, do you know how I can get any info on how it works, I thought they had a seperate control on the keyfob. I'm going to try and download a photo of the pump for confirmation. Cheers Ian

Over the last week or two when you started your TD6 from cold in the morning did you get an "on dash" message saying Pre-Heating ?

Well your pic certainly looks like the O/S of your axle

Ceegar for me please !

Well you best not as there may be diesel all over the floor in the morning

spitfire · Dec 19, 2012

Yes, but assumed it was glow plugs going through ignition routine.

So this is the wrong pump and a complete waste of money?

Showed the photo to the Parts chap at Land Rover who told me this what what I needed.

Nope - that is the message to state that the FBH (Fuel Burning Heater) is operating and warming the vehicles water system quicker than the TD6 engine can

Whilst "pre-heating" takes place your "leaking" pump would normally be sending metered amounts of fuel in "small pulses" to the FBH under your battery

If your garage has simply joined your pipes together then you no longer have a metered amount going to the FBH

Gravity or capillary action will eventually syphon fuel to the FBH and at best you will have a floor covered in diesel or worse when you turn on ignition in morning (well lets not go there)

OK heres what I would do at 20:48 at night

Open glovebox

Pull off fuse cover

Look on list (I think it is fuse 59) Auxillary heater

Remove fuse

This should disable the heater so as to reduce any risk of fire

Go back to garage in morning get them block off BOTH pipes and ensure no leaks

Replace pump once "in stock"

And now u can stop panicking !!

That looks like my example Pump B

If this had failed/leaked then I would expect engine running problems

Also that pump is not fitted where you have shown your leak

2.0_hippo · Dec 19, 2012

The "pre heating" message is the glow plugs heating up not the fuel burning heater

Hence you should wait for the message to go out before starting the engine

The message should only stay up for a couple of seconds

The fuel burning heater actually takes a good couple if minutes to fire up once the engine has been started

And there's no message that tells you when the diesel heater has automatically come on

Thanks Dave, The car is in the garage with the rear suspension stripped out, I've texted the owner to check for leaks before starting the car and to blank off the pipes before carrying out any more work. Any idea where I can get a pump other than L R and would you have a part number. Thanks again. Ian

On this occasion I have to disagree (hope someone can accurately put either of us right ?)

The coil light is the "tell-tale" that the engine glow plugs are "pre-heating" !

The in-dash warning stating "Pre Heating" only operates at temps below apprx 7 degs and indicates the FBH has kicked in

Oh right

Never noticed the coil light to be honest

I'll look at rave now to confirm
