1999 Tdi Power Problems Again

[fredthomas]

after many days of trouble free motering this infernal machine has yet another fault,

it now starts and runs ok, it still vibrates on pulling away but i just live with that but now when you get to 2100 revs in 4th or 5th gear the power just dissapears. makes for some hairy overtaking. it is not going into limp mode cos if you slow down it pulls hard til you get to 2100 revs again, also refuses to rev over 3500 revs, otherwise the car runs and drives fine,

if you go through previous posts you will see that i have had some major problems with this car, most have been sorted.

just to clarify i fitted an oil pressure guage to the car after seatkids warnings about oil pressure and this is within acceptable limite for the age of the car,

it has an afn engine and dome 162k miles, not i think very high for the engine,

 

vag com says it has an oc temp sensor, always has no problem with that,

lately another fault intermittant memory module error, comes up

i believe this relates to the pressure pipe from the intercooler delivery tube leaking but i blew it and it doesnt seem to be leaking,

 

any ideas any one

the only alternative is to scrap it but i like the car, i want to drive it, my lad and grandkids love in preston and i live in anglesey its a looong walk,

Did you inspect/change the small pipe inside the ECU when you was having problems before.

no not got that far yet, i just blew up the pipe and it seems to be holding pressure, i need to go to manchester sunday and i work long days (arriva) to time is a problem, i have been crawling about under this car for as long as i have had it, it would be nice to just drive it for a change, but this fault seemed to come out of the blue, it was going very well til this appeared
