i have 300tdi its lost power not sure why but it does not do it all the time check all the thing we can think of but still know joy. if anyone thinks they have any ideas please share.
-
have you checked the fuel lifter?
-
Sounds like you could have an intercooler pipe that's delaminated on the inside, partly blocking the intake.
Or check that the wastegate moves freely, it could be sticking and not allowing the turbo to give you full boost.
The wastegate is located under the exhaust manifold, there is an adjustable bar connecting it to the turbo which is held on with a "C" clip. If you remove the "C" clip then you can check the wastegate movement. :wink:

going to replace air filter anyway but it ok. to me something seam blocked but it,s a case for where is it blocked. have try the back feed all clear.could it be the fuel pump ??if so why does it work lol or at slow speed anyway hehe
-
Clouds of smoke when you boot it or travel at fair speed on a motorway?
My money's on turbo hoses.

I have had a similar problem,started about a week ago,Found problem: split in fuel line, at the front on top of chassis 6†or so before fuel line curves up to lift pump, happy - no, why, becouse i had a new fuel lift pump fitted Tuesday Grrrr. I should have been off - roading today in Snowdonia, but had to turn round and come back home because it was losing power.
-
no smoke at all . but i will look at every thing that has been said. cheers
-
have fitted new fuel filter have check all pipes and they are fine only one of two things i can think of and thats is exhaust or the fuel pump itself how will i know ?
-
another common thing on discos is the fuel sender where it comes out the tank. the pipes corrode and drag in air, lift the boot carpet, little round plate in the floor . unscrew that and have a look ,youll see the 2 pipes check em over .good luck alan........

i have been working on my discovery 300tdi for 2 days and still not found the cause of the problem.
-
what i have look at and done so far is this i have replace the air filter and the exhaust and clean the pipes refitted the lift pump and done the sedimenter ,bit of crap but not bad. not sure what to do next but i have no joy there still behaving badly it idles fine.
and it runs well for a 100 yards then only 10 mph it cut out. anyone else got any ideas as i am at my wits end with my husband lol :cry: :evil:

As I've just posted in Needbeer's thread. The fuel pipes are prone for rotting on top of the fuel sender. Remove the plate in the boot floor and take a look.
You'll probably find the pipes are coated in rust. Try a coating of vaseline, if that makes it run better, replace the sender unit (around £50 from Craddocks).

cheers i'll try that now and let you no the out come ive tried every think else
-
cheers gents all sorted now there was a blockage in the fuel line near the tank.
