300tdi disco problem

chatty203 · Oct 28, 2018

hi first time it happend today so just wondering what ur thaughts are so im not going in blind wen i take a look tomorow

So going up a steep hill today in 3rd gear and realised it felt like i was loosing boost and went completly flat on acceleration so i went into second had a little boost but then slowly started bogging down again went into 1st same thing untill i completely lost accelaration and the disco cut out so pulled over went to start it again it struggled to start but did after about a coupple of cranks now after that i realised if i changed gear early it was not too bad but if i take it to around 3000rpm i could feel the problem again

What are yor thaughts

on a really steep in too higher gear hill thats normal for a turbo engine as soon as revs drop boost goes and power drops fast ,but its worth checking fuel system, the pipes at the fuel sender under the panel in boot, the sedimenter inside of chassis rear o/s wheel and lift pump

it dose feel fuel related but its not like im letting revs drop im flying at 3000 revs then all of a sudden it feels like no turbo then the revs drop

Collapsed turbo intercooler hose???

My first port of call would be to check all boost pipes as mentioned above.

After that check the sediment bowl on O/S Rear wheel arch for gunk/grime/water. Also a fuel filter change of the filter in the engine bay might be worth it, making sure the correct bleed procedure of fuel is taken, do you have a copy of how to do this?

If it's none of those it could be the exhaust recirculation back into the engine causing the problem.

Fuel filter and sedimenter first, unless they have been done very recently

fixed it in the end it was sand in the air filter box was getting sucked up under load restricting air flow

Think outside, no box required.
