hi Badger, you are not going to belive what has just happened, i think we may be looking in the wrong place. i gort in from work this afternoon and i had arranged to take the lexus down to have the injectors replaced, got in the car ( reader plugged in ready to go through the cycle of clearing the code in safe mode ) and drove off. as you can guess i am waiting for the inevitable. it did not happen , it is 5 miles to the motorway from my house it drove there fine then on to the motorway 15 miles later no lights average 39 MPG. drove for another 40 miles still the same. so what is different ? simple i filled it up with diesel on the way back from lexus, so i think that it is a vacuum problem most likely with the filler cap.... i will try it again in the morning and let you know if it is still ok.

that is strange, i have also been looking on other forums the toyota D4D engine seems to have a lot of injector problems, if i am coorect that is the same engine that is in the lexus. i have found a place that can repair the injectors so i think i will go down that road ASAP, its worth a punt at £400 fitted. i with you no more diesels for me they are all too much agg, good luck with the 4x4 , i have shogun sport, love it apart from the fact that it is 3l petrol and averages 22mpg,

thanks, if you do the pump and it works i will go for that, if it does not work i will get the injectors done first and see if that works

mine does not really go into limp mode it show all the lights and mot rev at all it will just sit at 1200 rpm until i turn it off and turn it back on again then it will be fine, except for the 27mpg and lack of power low down the revs. its gutless at pulling away. did yours start like this ?

the pump was £1500 on its own and then they said they had to take the engine out, i have been looking at some other forums and D4D engines seem to suffer from injector problems, so i think i might try them first, Badger, i will wait till tues hopefully yours will be sorted and that will give me a better idea you can get injectors off ebay for about £200 a piece, i might see what they are new? i dont think lexus want to go near the diesels to be honest, they know they are aggravation

hi , well the car is back from lexus, they have identified 2 possible faults, injector 2 and 3 drain off to high and internal fault possibly on fuel pump. they have quoted £4456.00 to repair ....... so the question is what to do first? i fancy the injectors so i think i will look around for an options on these, lexus quoted £1400 to replace. any advice will be very welcome...

VSC , Traction ect...

on the up side, all the light now come on the dash and it has no fault codes, how strange is that???

well the car is now with lexus, on the way there every now and again it would puff out a a small amount of blue and white smoke, it would happen every 15 mins or so at about 70mph . the car only averaged 30 mpg . so i am not hopeful of a positive outcome . they gave me a ct 200 as a loan car and i have to say it has to be the worst lexus i have ever drove.

it also felt like it was slightly misfiring when i first drove it ( very briefly) , a lot of toyota forums have pointed to leaking injectors ( manual) so i have a feeling that it might be down that route

any that goes more than 200 yards on a morning before it stops would be good, however yesterday it went for about a mile then lost all power. turned it off and back on and it was fine, it is so bizarre.

i wonder what lexus they are going to loan me???

good for you, should be interesting to see the outcome ,

off to lexus with mine tomorrow will let you know what they come up, as no doubt i will be parting with a substantial amount of cash

i guess now you know why lexus did not want to get into doing it... they will have been there before?

just a thought, now i think about it my pump made a slight noise on start up, you would have to listen carefully but it was there. it would disappear quickly . does yours do the same ?

i have always run the car with additives to stop the DPF from blocking up, i just wonder if that has caused a problem on the seals on the fuel pump???

Badger, you are a legend. it shows the level of the ability of a lexus technician( unless they just could not be arsed ). i hope this cures the problem. are they a pain to get off and did you have to take the bonnet off...

i hope they come off, i have seen pumps on e bay for about £250, i would also guess that most pumps would be ok as it seems quite rare looking at the forums. if you get it off i think you should bill them...

i am not convinced that they truly know whats wrong, mine is in next week so lets see if they come up with the same thing?

what about the ECU ?

if it is not the pump, what else could it be ?

good luck, you deserve some,

i cant believe that, so its the fuel pump, looks like i am in the same pile of poo, and just to make things worse my wifes car has blown a head gasket... i feel your pain

hi badger at this rate you will have tried every car in the lexus range
