Rough running Tdi

did this start after your last refuelling stop?

Wolfie

injectors can suddenly go wrong. I had one suddenly stick open as i drove up a hill.

Could be something else in the fuel system. Have you checked the fuel filter? I have trouble with the pickup pipe getting blocked with crap gradually and you notice suddenyl when it reaches a certain point.

Maybe worth changing the fuel filter and funning a tank of fuel through with injector cleaner in it and see what happens to the problem.

Tom Woods uttered summat worrerz funny about:

Fuel pickup from the tanks also rot through on Discos and Rangies and can allow a small amount of air to be sucked in whilst showing no signs of a leak of fuel as it only happens when the pump pulls air and fuel through the pickup. That little gem gave me the run around for 2 years or so until it got to the stage you are at prior to the symptoms you now have it resulted in prologed cranking to start if the vehicle had been left a while as the fuel was able to syphon all the way to the back in to the tank other than what was left in the filter. This was on a 1990 Rangie around 2 years ago. May be wrong but another thing to consider if you start to draw blanks.

Not immediately. I'd done about 250 miles since the last fill when the problem appeared.

Chuck some injector cleaner in and see if that sorts it.

I think I will do that. It hadn't occured to me right away because I have always assumed that the various concoctions that are sold to put in your fuel tank are just snake oil. At this point it couldn't hurt though.

Roy

worth doing the fuel filter too like i suggested. they only cost a few squid and are an easy job.

Yup. Thanks for that suggestion too.

Roy Hi,

I have found that my 200Tdi started feeling more lively again and reduced its fuel consumption after changing the fuel filted (but then again it was not changed for more than 50.000 Km due to a mistake)

Injector cleaners do a pretty good job and a few diesel additives are worth their money also.

If you decide to change your fuel filter remember to prime it first with fresh diesel before putting the new cartridge in. This will save priming the whole system so as to remove the air babble. Tdi engines are supposed to be self priming but if you do prime the fuel filter this will also help the engine.

Take care Pantelis

I will be changing the fuel filter shortly, per the advice here, although it was replaced less than six months ago (so probably less than 9,000 miles).

Fair enough. I have already suspended my disbelief long enough to tip some into the tank this morning. We will see...

Today is a "suit and tie day". That'll have to wait till tomorrow. Thanks for the tip.

Roy

And don't forget to drain the sedimentor as well or the jellyfish will get upset ( assuming you have the buggers too) Derek

Its only unethical if you get caught

It should be changed at 6,000 - along with the other filters, and of course the water trap on the fuel filter should checked regulary..... like everyone does ;-)
