Hi,

I'm looking to change the fuel filter under the bonnet on the Mondeo. The filter is quite a large metal jobless and has a couple of click on connectors. Seems the system needs priming afterwards and Ford done have a priming pump - you have to use an external bulb, which I don't have.

Does anyone have experience of this, same as the 1.6 Hdi engine. Could I just turn the ignition on/off several times before starting?

Thanks - Rob

I think it'll self bleed Robert.

If you don't have the primer bulb on top of the engine under the tdci stamped cover then its probably got a lift pump intank so as already  said ignition on off a few times

Hold up!
If it's later model with metal filter then the top cover has a primer button built in (the top is reused on the metal filater type)

[henryd]

Having had a Google its seems the ford type filter top doesnt have the primer button that its cousins from frogland do so would suggest intank lift pump

Ignition on and you should just be able to make out the sound of the pump running, let it run until.it times out (30 seconds or so), repeat a few times.and the it should just start

I seem to recall, that when the fuel filter was changed on my 1.6 TD Mondeo.....the blokey that changed just cranked it over till it started.....tho he did have a booster pack on the battery whilst doing so......so no priming needed it seems 
and probably the advice of just turning the ignition on a few times would likely have to same effect 

[Marks DTM Calib]

He's a bloody Muppet then!

[TD]

He's a bloody Muppet then!

As are most "mechanics" but that's they way of things in garages.....only cranked for about 10secs or so before it started 

Bout to get stung again....as cba.....breaking at 30-40 ish is uneven.....and breaking at 70 produces steering wheel shudder....I reckon its warped disks.....not had that on a car for a long time.....but maybe Ford disks aren't as thick as other makes

I had Brembos on my last Mondy, which was a 2.5T 5 cyl. I think GSF have them on offer this weekend.  This one was a Lex lease car in its life before me - I got hold of the full parts history - had new Motocraft discs/pads fitted just before the end of the lease.

I chickened out in the end, after reading horror stories on the Ford forum. 
I had a spot of luck though, popped into my local Ford dealer on Saturday morning with said filter - said I needed help & could I book it in for them to change. They offered to do it there & then for me whilst I waited  . It all worked out nicely in the end .......

These modern engines need priming via software, I've done a fuel filter change on the VW. 5 screws and sub 5 mins to change the filter, once new one is in I had to activate the pump via software and run it for 3 mins to bleed air out.

Started on button afterwards, picks up better low down now. Apparently fuel filters every 60k, mine had done 30k, could feel the difference.

VCDS/VAGCOM does come in very handy....

Seen most diesels need to be primed via software? Unlike old 1.9's and non common rails were ignition off/on works.

Why is this any different to BMW diesels or Vauxhalls lumps? All still need priming. 

Also a damn site nicer job than Omega fuel filter

Most common rails can be primed with ignition.  Its older systems that generally need priming/bleeding.  Having to need access to dealer level equipment - i.e., more than a simple service reset tool - to do basic servicing is unacceptable in this day and age.

Given electric hand brakes, no dip stick engines, not even an engine temp gauge on a BMW 235i....

It's a fact of life sadly now, also given Hybrids appear to be the new diesel I doubt you will be able to access the spark plugs in a few years. Without having to strip half the engine down.

Again, most electronic handbrakes don't need dealer level equipment.  In fact, when I ran out of brakes in France in the Insignia and rang back to blighty to get a mechanic mate to bring pads and tools with him (as he was joining us in a few days), the first thing he said was "it's not f****** VAG shit, or I'll have to bring the computer thing"

[Lincs Robert]

The priming was done by the Ford guy using a little handheld bulb thingy with an air bleed non-return valve in series with the fuel system, so needed the correct fittings & after he'd tipped the half litre or so of diesel into the body of the new filter. He then removed the bulb thingy & it started first time. I suspect only a teaspoon of fuel was lost in the whole process.

Most modern common rails will self bleed with the in tank fuel pump, maybe VAG are going the way Merc did a few years ago and making it all software based (not a good thing!) for even the basic functions.

I suspect there is a way round it though, you just need to find the fuel pump relay

Forums suggested you could do without software, but had typical discussions of some saying it caused damage, others said it was fine. Same with rear brake pads, you don't need software. I suspect there are ways around it, but as I have VCDS might as well use it.

Regardless of how the system works, from a DIY perspective and having the software it was nice easy little DIY job.

[Marks DTM Calib]

You may well be seeing a forum with a bit of a lack of understanding and hence default to the obvious. 

Common rail setups have in tank pumps because if you rotate the high pressure pump without fuel in it then they can get damaged very quickly as the diesel is the lubricant.

So when you fire up the electrical systems then the system electrically primes, repeat a few times and its ready to go....no laptop needed  (which has GOT to be easier!)

Are VAG expecting you to seek dealer-level diagnostic supoort when you run out of fuel too?

[Nick W]

Are VAG expecting you to seek dealer-level diagnostic supoort when you run out of fuel too?

Would a German allow themself to run out of fuel?


So your question is redundant.

Oh, I've worked with German engineers for too many years, believe me...

I would imagine it's against the law to run out of fuel in Germany!

Ford tdci filter is a bitch to bleed,much prefer changing the fuel filter on the discovery.
