Intermittent (horrible word) TD5 loss of power.

Just when I decide to sell - someone up theirs having a laugh!
Its like limp mode if I keep the hammer down it will eventually clear and accelerate like the turbo kicking in - if I change down gear it stays limp until revs pick up. If I pull over and restart the engine it does clear it 9 times outta 10 initially.
It did happen a few years ago and I replaced the fuel filter with a Mahl and it cleared for a few weeks. Now its back. I did replace the fuel filter again with a Mahl last year. New injector seals last year. Recent new fuel pump. Bit of oil travel to ECU. People suggest a better fuel filter replacement?

Just remembered I do have a fuel leak on the far right pipe at the fuel pump - someones done a DIY on the pipe in the past and now it leaks - would this cause the loss of power?

If fuel can get out, air can get in and produce the symptoms you describe. Definitely worth fixing the leak first.

Wise words thanks.
