Ive just returned from abroad (work) to continue the saga with the 04 plate TD4. Previously, I had the lack of power and the Management Light came on at only 3500 revs. Also, the P1260 fault code came on with diagnostic equipment attached to it and I've changed the fuel LP sensor, but that didn't solve the problem entirely. Following some good advice from on here, I fitted a new fuel pump (the one behind the OSR wheel arch) and filter. However, being a bit tight at the time, I fitted a non-genuine (cost £60 compared to a genuine LR pump at £200) pump and filter to the car. OK, power has resumed, although not great, and the management light doesn't come on any more but Im not convinced the problem is completely solved.
Although I have no problems starting the car and it ticks over nicely, Ive noticed that the gear change (automatic) is not as smooth as it was and it labours to get to top gear. On a 40 mph road you have to increase speed to 50 then ease up and it drops into top gear. Ive also noticed that the fuel consumption has increased.
Could it be that the cheaper pump is not sufficient or adequate for the job? Has anybody else had this problem? Could be a case of false economy!!!
Also could it be another problem; HP fuel sensor faulty? I would be obliged for any advice or comments.
