V50 Electrics : Volvo v50 1,6D (06) DPF issues

[KanonTerje]

Hi there.

I was trying to figure out what's wrong with my volvo v50 1,6D (06mod), and I stumbled upon this forum and some related issues.

It all started with a clogged DPF.

Had it changed, and the pressure sensor, and the rubber pipes.
And the additiv tank refilled.
The engine also have had service (Oil, diesel filter), and the glow plugs have been measured, and are Ok.

But still it goes into limp mode for some reason, with no warning and lights in dash.

I check it with diagnostic tool and it tells me code 2A20, particulate trap faulty signal.

When the car runs idle the pressure sensor shows 0hPa (it's new), and I've even tried another, and same. But when I pull the plug it suddently jumps to 120 hPa...why?

Done some voltage Reading, but not sure if it's right...?

Strange thing is that the DPF exhaust temp sensor is also acting weird, it's like stuck on 99,96 C .. this is the old one. Could this be faulty and causing all these problems? ..And when I pull the plug it still shows 99,96 C ( and even when the engine is cold).

Any ideas?

I have some pictures maybe someone could take a look. Can send em e-mail.

Could it be a short circuit?

Best regards, Terje
