I own a 2007 307 s 1.6 HDI 110bhp with approx 77000 miles. When I first purchased the car it became horribly chuggy down low and would flutter under acceleration above 1800 rpm. Having read these forums I decided to change my EGR valve. This cured the chuggy feeling down low and made the car run a lot smoother to 2000rpm but then the car would not accelerate past 70 and would begin to flutter and vibrate almost lie it was missing slightly. In all gears except 5th the car would rev happily past the 2000 mark. However when I interrogated the fault codes with a basic scanner I got fault p0299 (turbo pressure low). Suspecting that I had not seated the EGR correctly I removed it and installed it again using a new clip and gasket. This has not effected the fault the car still fails to accelerate past 70. Having investigated more I have discovered that the p0299 fault only occurs when attempting to accelerate past the 2000rpm mark in 5th gear. The car itself I found to be over filled with oil when I bought it and also I have found what looks like diesel the air side of my turbo, this seems to have come from the breather half way up the intake pipe as its oily from there onwards? The oil level has been returned to the correct level and hasn't used a drop in 1000 miles? I myself am puzzled. If the fluid were oil I would expect a levels drop? Also there are no signs of oil burn under acceleration I get no smoke no matter how hard I accelerate? Any help/ advice would be greatly appreciated.

I did get the fault codes using a generic fault codes reader and every time I get p0299 after attempting to accelerate past 70mph

Can I then assume the solenoid and vacume are ok? I've noticed slight nick on the first stage blades if the turbo would this cause low top end boost?

If you cannot go over 70 even though you legaly can't :) you have something more than boost control wrong unless vacum is droping off once moving we have had this before on our taxis but they can then only do 50 !!

Do you get decent acceleration up to 70 sorry but your post above is too hard to read with no gaps.

Acceleration using the band of rpm up to 2100 is fine. Above that it stop gaining. Most noticeably in 5th gear. I even got cruise control to attempt to go from 70 to 75 and it tripped of registering p0299

Been and had the car put on the diagnostics system at the local Peugeot specialist and they seem to think the fault they found a fault with the turbo electro valve sticking. I'm assuming this is what actuated the turbo solenoid? Therefore it could be this I've also read it could be an air metering issue so I should try driving the vehicle with the MAF disconnected ?

Is an electro valve another name for a turbo solenoid? And what are the approx locations on a 307hdi 1.6?

Thanks

Silly question but is that the right hand side of the car when you are sat in it looking fwd?

With the car idling I pinched the vacume pipe at the bottom of the turbo and the valve arm was very slow actuating out is this normal?

Thanks for the help

Ryan

Also I've found a pipe with a lot of play in it on the turbo that if moved in the wrong direction leaks oil is this normal ? A photo is attached of the pipe.
