Hi all I’m extremely new here so sorry if this is in the wrong place. I can’t quite find what I’m looking for so wanted to start my own thread. I have a 307 1.6 HDI diesel on a 07 plate, 170,000 on the clock and until lately has been perfect.
Last week I noticed a loss of power mostly on hills but it was intermittent then last night when I pulled up at some lights I noticed a small amount of smoke from under the bonnet, I checked and no fires!! I’ve also notice a strong smell of fumes outside the car but I’m 99% sure it’s not an injector as I had these done a couple of months ago and can’t see any of the signs that would suggest this. Also no lights or warnings on the dash. The loss of power now seems to be all the time. Please can anybody help? I know she’s old but without her I’m really stuck and would really appreciate some help and advice.

It sounds like the injector seals need a close look at as they were disturbed before and a possible diesel leak.I have traced fumes by running the engine when its dark and using a torch followed the fumes to the source...hope that helps and good luck..

Live data on PP2000 may help if you can't find see anything immediately obvious

ps....exhaust manifold gasket will be worth a look?

Thanks for the advice so far. I like the torch idea so looks like it’s gunna be a late night for me tonight. Also I went out at lunch and revved her up and if I gradually increase reves it gets to 3200 then drops back to 3000 and just bounces between the two but if I apply more pressure to pedal the revs go up but feels lumpy. ( I can feel a jerk / heavy vibration through the car) any further ideas?

A little update on this one, I ended up with the dreaded anti-pollution warning so from reading on here I started my investigations. First off, I checked turbo and clamps, all ok, then I had the fuel filter off, no problems there, then I noticed the breather from the crank shaft into the inlet pipe was lose. So as a temp fix to see if this could have been the problem, I pushed the breather tight in and have duct tapped in place and hay presto, no more anti-pollution or engine light. I have a long run with the hill I first noticed the issues on tonight so I’ll update how it is then work a permeant fix out if its cured.

The breather is a poor design on this engine, it isn't a tidy fit at all. Hopefully the gaffer tape has sorted it for you
