you can rev the vehicle and easily squeeze the rubber intercooler pipe could the waste gate be constantly open or is there anything else we could try

Yes; you can start with the engine code - RH... something?

What is the actual boost pressure compared with the target boost at the same moment?  Boost deviation flags a code very quickly.

Check the MAF readings too - it won't boost much if it thinks there's not much air coming in.

No wastegate - VNT turbo; but many other things can cause a loss of power - even a blocked air-filter.

We have had lots of problems with the 307 2.0 HDI. We only have problems with RHR engine code which is the 136 bhp.

They suffer alot from turbo's not working but also the turbo actuator pressure sensor which is a pain to fit. The symptoms we mostly have is that the vehicle whilst being driven will hestitate on partial throttle in any gear around 1700 rpm. When you have the bonnet open with the car stationary, if you hold the revs around 1700 rpm so the turbo starts to boost. The top intercooler pipe will start to bulge as the turbo starts to hold a little boost.

They also suffer from the small vacuum pipes splitting which connect all the turbo pressure sensors and EGR pressure sensor. Also make sure the black plastic housing which bolts to the inlet manifold is clean inside around the two butterfly's if if has the hot intake and cold intake. We have had to change them on Volvo's which use the same engine.

We have not had much problems which Air Mass meters but you never know. Keep in mind if the vehicle is running a diesel particulate filter. Peugeot have been using them for a while. They have been known to block.

angus has stated there is no waste gate, i can suck the pipe going up to a diaphram which operates a lever going into the exhaust side of the turbo and this will increase the pressure in the intercooler pipe, how does the other type of turbo work from the vacuum provided from the elec valve on the front of the engine, are all the elec valves for the butterfly,egr and turbo the same

What is the engine code? I don't think they all have a VNT, I think most have normally open wastegate turbo.

In the chassis/vin number are 3 digits. The first two should be RH - we need the following digit

HYUNDAI/PEUGEOT TECH = GLUTTON FOR PUNISHMENT. IF YOU WANT HELP PLEASE SUPPLY THE LAST 8 DIGITS OF YOUR CHASSIS NUMBER
