Were is the turbo boost on a peugeot 607 2005 2.2 hdi

it could be an indication of a problem with the turbo system. The sound you are hearing could be from a turbo wastegate, which controls the amount of exhaust gases that enter the turbocharger and can make a sound similar to a blow-off valve.

Check the hoses between the turbo to intercooler and on to inlet manifold. They split.. No boost, no go.

Check egr valve system, check turbo boost solenoid, is it hot ? It should be war but not hot. Check turbo waste gate. Remove the black assy that hold the butterfly valves inside that the turbo air hoses connect onto to and make sure they work by sucking on the tubes to activate them, they are sring opened or closed and the engine vacuum system opens or closes them.

Take it to a citroen agent. the 2004 and 2005 had faulty turbos and thats the fault. Citroen parts are the same but cheaper.

i have a peugeot 407 hdi 2.0 turbo 16 valve engine and i wont to now more about timing markes where is

Clean/Change air filter, fuel filter, air filter, turbo filter. Clean and check EGR valve and Turbo gate. Check the hdi fuel pressure. Open the injectors and clean it. Give it a try and may be you can save 600 euros.

My book shows that P0245 is the super/turbo charger solenoid "A" voltage is low.

Chech the solenoid that operates the turbo, its located beside the EGR solenoid on the bulkhead, I had one where the vacuum pipe was blocked where it connects to the brake vacuum pipe.

You have a bad injector sir.

Hi, I have a 2.0HDI Expert which was doing the exact same thing as yours, blowing thick black smoke, sluggish and loss of power on gradients, a hissing sound and surging. I replaced the air flow meter but that didn't help. I was told to replace the turbo but a turbo expoert told me not to as it would blow white smoke if it was faulty. I was then told to replace the injectors but a diagnostic test showed them to be functioning fine. I was then told to look at the intercooler which had thick sludge at the lower left pipe. I replaced it today - Sunday 12th July and it is now driving like a new van. It now pulls me up gradients with ease in 4th and 5th instead of having to drop gear to get to the top. I got a replacement from Euro Car Parts for £147 inc VAT. To tell if this is your problem, look through the gaps in the lower section of the bumper at what looks like the radiator and look for sludge over the inside of the bumper and all over the pipe where it joins the back of the radiator (intercooler). Also open the bonnet and look down behind the grille for the same sludge. Hope this sorts it for you. Barry, Newtownards, Northern Ireland.
