2.4 TDCi 56 2007 115 ps Diesel knock engine tapping

Postby Rob hemlock » Sun Mar 10, 2013 5:20 pm

Hi I have a tapping/ knocking sound, it sounds like when injection trimming Is out to my knowledge, of corse it's commonrail so timing is not the fault seems to be when accelerating it kicks in and its worse when cold.
It's done 100k fsh I did hope it would cure with a service, I change all filters and oil still the same!
Checked injector coded correctly done self learn ect no change
Changed air mass no joy

Many ideas some as follows
Some my ideas as trained mechanic some from reading here!
From the bellow or indeed if you can think if something else I would like to know if some one else has had same symptom on same engine?
Where do I start ?
My thoughts:
Air leak fuel housing
Air leak intercooler or pipes
Wiring knock sensor harness
Timing chain or tensioner
Rocker/cam followers worn
Thankyou

Most likely wants a prv on the fuel rail, suction control valve on the pump, and then a pump learn, pilot learn and PCM update on Fords IDS system.

Hi have you sorted your problem yet I got the exact same symtoms on my transit but mine is a 2.2 tdci my problem is the fuel metering vavle on the fuel pump but ford wanted to change the whole fuel pump instead of the fuel metering valve don't know if that helps but that's the problem on my transit

This is a realy common problem on the mk7 transit, you nead to change the fuel metering valve on the pump and the preasure relife valve on the fuel rail. then get someone with suitable diagnostics to learn them to the van.rgds Andy

all good sound advise thanks, I am since lead to believe its a common fault on most transit models.

I have priced up from Ford TCH Dealer
@10% off retail cost for trade

£51.11 + VAT - PRV - valve
£75.00 + VAT - Fuel metering valve

so unless anyone recommends buying else where
I will order these and fit this week.

been offered use of special socket to remove metering valve
and also timing chain holding tool if I decide to remove the pump to fit on pump away from engine bay
for those that have done before would you do the job under bonnet in the engine bay or remove pump to get better access?

Now fixed, fitted fuel flow sensor back of pump and pressure relief sensor on common rail
Ran better but not quite right, did the pump learn on launch x431 spent ages trying to get it to successfully complete pump learn, but no joy, then I tried a friends snap on machine it completed pump learn first time van runs a dream.

Thanks to all for your help
And Thankyou Andy for your tips over the phone I am very grateful.

I just need to sell it now was my first van purchase this time round, I am getting back into vehicle trading again
Never use to be this hard.
