Hello there
I have a nice 2009 Honda Accord 2.2 i-dtec 8th gen. with 117.000 miles driven.
4 weeks ago it gave me the "DPF clogged with an explanation sign". I pulled over, and the car was transported to my mechanic. He sent the DPF to a professional cleaner, changed a temperature feeler in the DPF and I was set to go again.
One week later it again showed me the "DPF clogged with an explanation sign" I gave my mechanic another visit and he spent a lot of time with his tester (a proffesional tester that is - not the one you buy on Ebay!) but there was no errors to find.
Only thing he found was a warning for the inlet manifold shutter valve not working as it should.
He took the entire inlet system apart and cleaned everything, both the EGR-valve, the inlet manifold shutter valve and the inlet manifold shutter valve housing.
He drove a long trip using various driving styles and everything worked perfect.
I picked up the car the day after, and after only a few miles the warning came back.
Again, back to the mechanich, he did a lot of stuff, resetting etc. but still no errors. Another long test trip where the car drives like a dream.
When I got back behind the wheel and drove a few miles, the warning once again came back.
When the warning comes, the car goes in emergency programme and looses all its power.
Changing the inlet manifold shutter valve is of course an option but it is extremly expensive and it takes a lot of time to change it.
Does anyone have experience with other solutions? What can actually be wrong with the inlet manifold shutter valve? Honda says it is non-repairable, but perhaps they just want to sell me a new one?
If its possible, can a used inlet manifold shutter valve be found and is it recommended?
Actually my mechanic thinks that the inlet manifold shutter valve is working fine since the computer doesnt report any errors, and it is some kind of wrong-value somewhere in the system that causes the car to show the warning and go in to emergency programme.
According to the tester the DPF is working like it should regenerating every time it needs to.
