Thanks, main mistake was that i broke Y switch so i bought another with 2 new hoses, one from turbo i connect to Y and i see that it goes to something else, it will be very helpful that you provide me photo of line from solenoid that goes to turbo, this from vacuum pump to solenoid is good.

ill get you some photos first thing in the morning (about 12 hours from now)

If I remember correctly the "top" (domed end) connector is vacuum feed and the lower one feed to EGR, Turbo etc

You're right, I have one, comes from a Volvo, but it is the same as Peugeot, top is vacuum and lower is out to actuator

The solenoid valve connectors are colour coded Turbo Grey Plug, EGR Blue Plug and Black for Doser valves.
The hoses should be colour coded one hose should have a white strip/dot which goes to the valve connector with the dot by it.

Right, but i need where bottom line goes

Actually iv just spotted it in the photo

when I ran my fingers down the pipes to check them that y connector snapped off compleatly

View attachment 92458

This Y i broke and replaced but not sure what lines go in

 

[THR0BIN_WOOD]

right ill get a flashlight... gimmy 20min

 

[THR0BIN_WOOD]

this one goes to here

 

[THR0BIN_WOOD]

this one goes to here

its attached to the y connector

 

[THR0BIN_WOOD]

the other side of the y connector leads up here

Hi, just follow the vacuum hoses, from the vacuum pump the hose go to the vacuum reservoir, under the intake manifold, on the engine block, from this one the hose comes out and split:

• one hose go to the valve on top of the A/C compressor and out to the actuator of the inlet manifold flap
• other one go to the valve near by vacuum pump and out to the turbo actuator

 

[THR0BIN_WOOD]

is that what you needed?

 

[SrdjanN]

is that what you needed?

Exactly, thank you

I will try for 1 hour.

 

[SrdjanN]

Ok,

good news is that i am not getting safe mode after 15 minutes of driving, and lines are now connected well.
but i get black smoke, on idle it is unstable and when driving it sometimes stops turbo boost and it change my rpm's

Did you consider taking the car to a mechanic? You obviously don't know what are you doing and you could make it worse.

 

[SrdjanN]

here are codes i get from ECU,

P2565 Turbocharger Boost Control Position Sensor Circuit High.

I am again in safe mode, but now i am getting it after 15 minutes driving,before it was on 2 minutes.
But now my car is much more unstable on idle...

 

[SrdjanN]

Do i need to fix this lines connection with shells?

and also on solenoid?

It is T switch instead of Y.

 

[SrdjanN]

I have blocked EGR, so few last codes are because of blocked EGR, also i was empty tank yesterday, so some codes are because of that i think.

 

[THR0BIN_WOOD]

 

[THR0BIN_WOOD]

some of those codes still relate to the solenoid valve. have you cleared the codes after you fixed the pipe?

Not sure if i can clear codes by this cheap ELM327 , but it is not still fixed, i am getting safe mode, idle is unstable, black smoke, etc...
Maybe because I didn't tighten the hoses?

>> p0490 <<<

OBD II fault code P0490 is a generic code that is defined as “Exhaust gas recirculation (EGR) system –“A” circuit high” and is set when the PCM (Powertrain Control Module) detects an abnormally high voltage in the EGR (Exhaust Gas Recirculation) valve's control system

thats a glow plug they are extreamly hard to change on this car
they are right at the back of the engine and you have to work blind

dont worry about this one right now

strange to get this code on its own? normally comes with p1435 Additive system fault

>> p0098 <<<

P0098 Generic Intake Air Temperature Sensor 2 Circuit High Input

check these sensors are plugged in. that could cause blacksmoke and poor idle

>> p0406 <<<

P0406 means that the exhaust gas recirculation (EGR) sensor A has high circuit voltage. The ECU detects this high voltage and sets a Check Engine Light. The Check Engine Light will be illuminated on the dashboard.
What causes the P0406 code?

Failed EGR valve
Excessive carbon buildup
Open or short in the wiring harness
Poor electrical connection
Leak in the vacuum line to EGR valve

>> p0409 <<<

The P0409 code is set when there is a malfunction in the exhaust gas recirculation sensor A circuit. Low voltage from sensor A is detected by the ECU. This causes a Check Engine Light to be shown on the dashboard.
What causes the P0409 code?

Faulty EGR valve
Open or short in the wiring harness
Carbon Buildup on EGR valve
Failed EGR solenoid or position sensor

>> p1471 <<<

Excessive ash accumulation in filter
Faulty MAF sensor
Exhaust differential pressure sensor fault
Modified exhaust system
Faulty EGT sensor

check this sensor is plugged in
