Reached the bottom of my lane , warning on screen light on dash , ive been waiting for this , my outlet manifold is blowing which i think has caused said fault codes , were leaking gas were gulping air... Any pointers if i maybe wrong,

Egr is new original part. Ive soot upside the turbo which leads to outlet manifold and this is the route its taking.

Codes:

Fault Code:	P0238
Description of Fault:	Turbocharger pressure signal : Short circuit to positive. Short circuit to positive or open circuit Value too high (Above 4.8 V)For 1,2 second.
Conditions for Fault to clear:	Ignition on
Downgrade Modes whilst Fault is active:	Default value for the air flow as a function of the engine speed and of the flow injected. Inhibiting of the diagnostics and air flow sensor plausibility. Cutting of the EGR butterfly (turbo air cooler), EGR valve and bypass butterfly (inlet air heater) in all operating modes.
Symptoms:	Noise Diesel fuel consumption a bit higher Lack of power
Suspect Areas:	Turbocharging pressure sensor Turbocharger position copy sensor Vacuum problem Variable geometry of the turbocharger jammed in the "maximum turbocharging" position Faulty turbocharger

Fault Code:	P0401
Description of Fault:	Air system fault : Measured quantity of air higher than the setting. Discrepancy for 10 seconds between the air flow setting and the measured air flow. - Engine speed between 750 and 2750 rpm
Conditions for Fault to clear:	Vehicle driven for 5 minutes, remaining below an engine speed of 3000 rpm
Downgrade Modes whilst Fault is active:	Deactivation of diagnosis of coherence on the flowmeter
Symptoms:	Noise Diesel fuel consumption a bit higher Lack of power
Suspect Areas:	Electric exhaust gas recycling valve Air mixer Air flow meter Air leak after the compressor Air flow sensor information incorrect Vacuum problem Variable geometry of the turbocharger jammed in the "maximum turbocharging" position Turbocharging pressure sensor Clogging of the exhaust gas recirculation circuit

Fault Code:	P0409
Description of Fault:	Electric EGR valve position copy signal: Valve sticking during the initialisation. Valve sticking for 8 seconds during the initialisation of the powerlatch (between switch off using the key and the ECU going to sleep). The following conditions have to be met: - The engine coolant temperature should be between 10 and 100 ° C - The battery voltage has to be between 10 and 15 volts
Conditions for Fault to clear:	Driving for 5 minutes
Downgrade Modes whilst Fault is active:	-
Symptoms:	Jerking/stalling Smoke from the exhaust Lack of power Starting problem
Suspect Areas:	Electrical harness Connector Exhaust gas recycling valve Engine ECU Fouling

Thats give a few answers to what im experiencing , looks like a few hours tinkering is due . Thanks for the code tables marc very useful.

Im smoking when i pull away ive that grunt blowing sound the smoke is dirty ,it clears fast. Im thinking oil is passing through the turbo so it looks like i might have to have an oil catch can before the turbo. Im not losing much power the turbo kicks in nice when needed.

Works when the car is immobilised, kids in the area love watching it slowly sweep side to side.

Started the tinkering today , top & bottom nuts on the front manifold one was finger tight the bottom was half way out a lable on the new dpf had nicely burnt off covered everything with ash , ive oil here there and everywhere to sort out photos tell what sort of a morning ive had. Having a break now a cup of tea & let the shower pass then back out to clean up and put everything back in. So much to move to get to work on this car its unreal.

As a fellow 1.6 HDi in a 206 tinkerer, I can confirm, yes everything is crammed in. Notably highlights include a bolt between gearbox and engine block that needs the DPF removing to allow access. Air filter is a pain to get at (though it's worse with the 1.6 HDi in a Citroen C4 though - tucked even more under the windscreen!)

Unless you have already removed them, you've a couple of heat shields missing - one above and another below the exhaust manifold. Actually that's another "how the heck is this supposed to come out? That big heat shield running down the front of the DPF is such a pain to get out too!

It's a lovely engine in a nice little, light 206 - good fun

There are ways of improving access of course.....
