Car Holding Back At 3 Thousand Revs

[carl]

Hi

My 57 plate 1800tdci galaxy is juddering at three thousand revs ... does anyone have an idea what this ... could it be a fuel filter problem .. thanks

[big_kev]

Hi Carl,

 

Sounds Turbo-ish to me.......however hopefully one of the MK3 guys will confirm this ( or not).

 

 

 

 

 

Can one of the Mods pop this into the MK3 section, ta

. thanks for the quick reply but i dont think it is the turbo (hopefully) i thinl that kick in at 2 and a half thou revs becuase it has loads of power until hard acceleration , when it satrts ti judder i hold back on accelerator and it picks up gradually.. could this be the fuel filter?

No, it isn't the fuel filter.

 

If I had a fiver for every time some buffoon suggested changing the fuel filter as a solution to a problem I wouldn't have to work half as hard as I do.

 

The fuel filter is a service item much like the oil filter or the air filter, it is designed to protect the delicate injection system from damage caused by possible particulate contamination in the fuel.

 

In practice the fuel pumped in this country is pretty clean and the fuel filter doesn't have to do that much work, nevertheless it has a minimum service interval so that the manufacturer can guarantee the longevity of the fuel system in all the countries where the vehicle is sold or can be used.

 

Your 1800 TDCi is a modern common rail diesel and as such has two fuel circuits, one low pressure mechanical (where the filter is situated) and a high pressure unit injection system which is electronically controlled by the ECU.

 

Your fault sounds distinctly electronic to me, you'll need a diagnostic scan to find out exactly what is wrong.

wastegate actuator on the turbo could be stuck

 

some other things to look for in the rear view

 

BLUE SMOKE from exhaust - Causes: Engine is burning engine oil, injection timing is incorrectly set.

 

BLACK SMOKE from exhaust - Causes: Too much fuel is being delivered to the engine or the fuel that is being delivered is not correctly atomised, Exhaust Gas Reciculation (EGR) system has failed or is incorrectly set of has become clogged with soot.

 

WHITE SMOKE from exhaust - Causes: If the ambient temperature is low, steam which is normal and usually clears, if the smoke never clears, water is entering the engine (cylinder head, head gasket, liner problem).

 

GREY SMOKE from exhaust - Causes: Injection timing is incorrectly set, fuel is not being atomised correctly,

something other than diesel has been added to the the fuel tank.

 

METAL PARTICLES FOUND IN FUEL FILTER - Cause: Injection components have begun to disintegrate.

thanks for that ...... the only reason i thought it could have been the filter is because a very similar fault happened with my 2ltr tdci mondeo . and peoples changed the filter and it worked perfect ,,, i will get it on the diognostic comp aswell

thanbks for your explantion i have no excessive smoke at all ????

Isnt it under warranty?

Well that maybe what the service manager told you, but it wasn't the filter causing the problem, only the tech who fixed it would know what he did to fix it. :)

it WAS the Fuel Filter ,,,,, i spoke to 3 diferent ford dealers and they all said 90% of power faults is the fuel filter .....

so who is the BAFFOON now

[seatkid]

Its spelt BUFFOON. :rolleyes:

 

I'm inclined to agree with Sepulchrave, I don't believe a lot of what dealers say. Not that I'm particularly interested in Mk3s but I believe the majority of running issues with these diesels are to do with software and injector problems. If they fixed it, it was probably because they updated the ECU software at the same time they changed the filter.

Hi carl i have worked in a well known electrical shop for more years than i can remember .

 

When customers ask about there repair and I used give a full breakdown,there eyes often glaze over as turned into a long education to which the customer never seemed to return for new business.

 

 

so as i got older i realized the customer was in the first case only pretending to be interested to be polite as its better that the customer doesn't think that they haven't invested there life savings in screaming pile of poo

 

So in turn i am also polite ;) and say it's ready to use phases like "would you believe it was only the...."

 

Customers like you carl now return in droves

 

politics's eh :rolleyes: clear as mud B)

[sepulchrave]

Bingo, now help yourself carl 'cos I'm done here.

 

Byeee. ;)

Guys, stop picking on a newbie......

 

 

Carl, come back and let us know how the diagnostics went.

Thanks kev ,,,, it was the fuel filter holding the fuel back. when i took it off the whole filter was twisted ( like it was rung out ) its running great now... so to you and the guyds the guys who were supportive in this matter ....

Having owned a few Mondys Carl, it's not the filter itself that causes these symptoms. It's the connecting pipes to the fuel filter housing that are not up to the job and over time they bleed air in and unless you bleed it off and replace the pipe connecting clips, the problem will remain. By changing the filter, the air is bled off until the next time it occurs.

Quite agree!!

 

Some of these comments are outrageous!!

Funny thing email's and forum posts they never really show the body language or show the style of a cheeky school boyish glint in the eye so i think all comments should be taken with a proverbial 'pinch of salt' :D love you all hugs'n'kisses all round now could that be taken the wrong way ;) seriously lets move on and get back to the job in hand helping other fix stuff which i think is all our goal . Cant promise not to relapse to my inner child one in a while ;)
