You have trapped air in the system, did you fill the fuel filter up with clean diesel before you installed it. If not remove it and fill it up

    You have air trapped in the fuel line due to not filling the filter before installing, this is outlined in the factory service manual, now that air has migrated into the supply to the injectors you may need a dealer to get it purged out of the system.

Why cant my car reach top speed. the reves also can not pass 1.5

sounds like you are either not getting enough fuel , re-prime the fuel filter, ck the air filter , take it out for a run and see if it makes a differance , a air filter will do this for sure, even new ones , oil filter should have no affect on the running of it at all ,either air or fuel problem with is ,

You might have an air lock in the fuel system. The lines from the injector pump possibly need broken loose at the injectors and cycle the fuel pump several times until nothing but pressurized fuel comes out.

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..

Need to tune up my truck what will i need to replace

Hi Jeffery, You forgot to say if it has a petrol or diesel engine. In the case of a petrol engine, replace the the oil filter, fuel filter and air filter, and the spark plugs. Other than these items there is little else to do, as the engine performance is entirely controlled by the management system. The only difference between diesel and petrol powered vehicles during service, is that with diesel there are no spark plugs. Remember in the case of a diesel to fill the fuel filter with clean fuel before fitting it to the housing. Doing so will help in expelling the air from the system and make start up easier. Also fill the oil filter with the same multi grade engine oil used in service, so that on start up the engine is lubricated more quickly. Regards John

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.
