Peugeot 807 Exhaust particulate filter is clear elois fluid half full, very sloe acceleration till about 3000 rpm when turbo boost cuts in and then it speeds up but not when in 4th gear or going up hill. Engine tends to die going up hill regardless of dropping down gears to increase rpm, turbo boost hardly occurs up hill. New turbo boost solenoid valve fitted, maf sensor renewed, no fault codes show up on diagnostic tool. Normal road diesel makes it worse, top of the range diesel produces a slight improvement. Did redex, no change. Egr system all ok as are emissions.

does it get worse as it runs? this would indicate exhaust problem. could be mass air flow

SOURCE: RPM Oscillating

have you had the vehicle speed control reprogrammed if not that could be your problem

SOURCE: P1401 still after replacing EGR pressure and EGR valve

Yes that is what is wrong the intake manifold is plugged with carbon restricting EGR flow you need to clean out the ports to correct the problem if you run the car to long you will burn the DPFE ( the EGR pressure sensor ) out agian

SOURCE: fault code p0245 puegoet 406 turbo fault

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

Testimonial: "cheers for that x18wheeler60 thought it was low pressure not voltage,dont suppose you no which selonoid might be causing this nightmare."

Hi

It could be a number of things, I would check the EGR valve first as that is quite common on the HDI EGR "exhaust gas recycler" reuses any unburnt fuel in the exahust gas and forces it through the engine to keep your emmissions down and improve economy. often these get mucky so you can remove them and spray them with carb cleaner! do not use anything else to clean them.

To check also any air pipes that have splits. tears, rips etc have a feel around the underside of each air pipe as again this can ause that fault.

Lastly check the air mass sensor going into the air box, I cannot reacll where it is on that model but they are very obvious once your looking at it. normally a wire going into the main air intake of the car, unplug or unscrew it and again clean with carb cleaner and refit.

try these before you pay anyone, lastly it could be an injector leak sucking in air, you can test this if you can get to the injectors, poor a little water around each one and see if they blow out any water or bubble up and **** the water in, this can be a cheap fix but the labour invloved may be expensiove, in all honesty buy a haynes book as its pretty simple just takes a while.

Hope this helps, if you are unsure what I mean then get back to me and I will explain.

Dan
