Hi my name is***** you get this resolved or still need help?

Customer: replied 7 months ago.
Your the first tech to respond.
But, I did some research and found that the light that turned on means the dpf filter needs to be cleaned. So I have sent the filter for cleaning. I still don't know what the codes mean. Any help is appreciated

Check you turbo and intake piping for leaks and your bypass valve solenoid for proper operation.

Where is the bypass valve solenoid located.
Customer: replied 7 months ago.
When you say bypass valve is it the same as the turbo actuator?

Hi. Yes it is mounted to the turbo. Click on this link for the bypass valve replacement procedure and information on the valve.

I actually googled these instruction already.

Okay great. How are you making out on this?

I help on here in between jobs as time allows so if you need further help I will always respond back on my next available logins

I got the valve off.. But what do I look for on the vave its self. Is there a way to tell if it has gone bad?

Check to see if it is sticking or has excessive carbon build up and if so it is usually replaced as it is rare to get it functioning properly by trying to clean it

Customer: replied 7 months ago.
Ok. Should the piston inside move freely. Even with the touch of my hand. Right the now the piston doesn't move. It feel jammed.

Is the solenoid functioning that moves the piston? It should not be completely jammed but the solenoid is what moves it.

Customer: replied 7 months ago.
Valve seems fine. It doesn't stick.
What can I look at next?
Customer: replied 7 months ago.
The only thing I notice is.. Sometimes the metal ring with a orange o ring under the piston pops off sometimes.

Are there any leaks if you were to pressure test? This would cause low boost pressure.

Customer: replied 7 months ago.
I am trying to get a hold of pressure tester. But the are hard to come by unless you order and wait for it to arrive.

If you have trouble finding a set up you could always adapt low pressure regulated air to say 15 PSI or so and then spray with soapy water to detect leaks by air bubbles. Let me know
