    sounds like a fuel pressure problem.. can't imagine a fuel filter replacement causing that.
    do you have the correct Diesel filter?? maybe the Gas filters are different? Sorry I can't be more help

SOURCE: Fuel filter

There is no need to change it frequently. If there is a loss of engine power or if throttle cuts out then may be its the time to change fuel filter. It is recommended by peugeot to change fuel filter (but depends on fuel purity) after every 36000 miles.

You can clean it yourself
Dipp the whole filter body in carosine oil tank and leave it in there for about 20-30 minutes
Pour some petrol in filter with the help of plastic piped and apply a slight air pressure (use a piece of pipe to blow) in the reverse direction (marked with arrows) of fuel supply to clear residue and heavy oil composite that clogged in filter.
Repeating the cleaning process 2-3 times will clean the filter to reuse it without the need of a new one to buy.

What type of oil do you recommend for my 2005 6.6 Durmax. And should I change the fuel filter at every oil change.


Rotella T 15w40 is the standard for diesel engines. I would highly recommend changing the fuel filter every oil change.

Bmw diesel wont start


I'm guessing that you got an air lock in your fuel system as a result of your changing the fuel filter... I certainly don't know about a BMW diesel, but in most semi-truck engines, there is a priming pump just for the purpose of getting the air out ... and the fuel into.... the fuel system. I've even been known to fill the filters with diesel fuel before screwing them onto the base.. This is risky because of the possibility of allowing some foreign, unfiltered debris to get into your pump and/or injectors, just because of your putting unfiltered fuel into your filter... Check and see if there is some kind of priming pump close to the filter. Also, a possibility is that you may have an electric fuel pump.... as to where all you may need to do is loosen a fuel fitting on the pressure side of the pump and filter.... and allow the electric pump to purge the system of air.. I confess to my lack of knowledge on your BMW.... but, I do have some basic understanding of most diesel systems... Good luck..

I just bought an 03 td4 gs freelander and the oil on the dip stick is black, this is my first diesel car so not sure if this is o. always had petrol and it's like golden syrup in them? :-)


diesel engines do run dirty if this was my car i would change the oil and oil filter as a mater of corse, at lest you will know its been done then, also change the fule filter and have a look at the air filter as well
diesels dont like dirty fule or partly blocked filters, for what they cost its well worth the effort if you have only ever run a petrol engine you will find that the diesel need more servicing more often if you leave it unserviced the engine wont last as long as it could so dont skimp on the servicing or you wont be saving pennies you will be spending pounds

Volkswagon carravelle failed m.o.t on gas emmisions tried lamba sensor no improvement any ideas. 1995 model


is it petrol or diesel?-if its petrol try removing air filter-if its diesel you will have to change oil filter,oil,oil filter and fuel filter in one job lot-this usually works! if not as a last resort find the diesel screw on the fuel pump and turn it down(anti clockwise i think)-note how many turns-you will notice a horrible loss in power,but you can reset it after the test,because no-one will care then

The most critical things in owning a diesel are the air and fuel filters. Irregardless of what the owner's manual may say change the fuel filters at least twice a year, spring and fall because the oil companies change their additives in the fuel twice a tear. The air filter should be done at least once a year. Keep a close eye on the water in fuel warning and fix it when it shows up, your owner's manual should have the steps to take. Most diesel's call for 15-40 diesel oil, there's no reason not to stay with it. Pick up a copy of Haynes Diesel Engine Repair Manual, part # 10330.It will save you a lot of time,money and headaches. It costs about $20 at the auto parts store.
Before you make any decisions to start tinkering with it to increase power do your research. Diesel's work well because everything is balanced and even though supplier's may claim you won't have to change anything else, don't bet on it. Bank's is a reliable authority on diesel performance to judge decisions on. Hope this helps.

Sounds like an ECU issue.  check your fuses, see if you can get an error code from a scanner, they have one at most checker auto stores that you can use for free.  Could be a Intake Air Temp sensor or a Throttle Position Sensor.  Thats what I would start with.  Good luck.
