I own a gray e82 120d manufactured 2009.

the other day while I was driving my car, this engine light appeared.

I could feel a low performance of the engine when accelerating while the light is on.

I had my car checked by just near home engineer.

error code was like

480A DPF being excessively clogged - History
- 4A6E DDE: GLOW PLUG, CYLINDER 1 , ACTIVATION - Current
- 4933 air to EGR mass flow, plausibility - Current
4DFF swirl valve controller position control - History
4E09 Swirl flap, plausibility: - History
3F25 boost air hose monitoring - History


I had whole DPF took out cleaned and flushed by a mechanic.

Now I'm not sure the engine light appeared because the pipe and manifold including egr is clogged or simply the valve is fault.

Please help me with a low budget.

Thank you in advance
