Hi.
A4 B8 2008 CAPA 3.0 V6
Some back story.
So Im having problems with dpf. 870km ago I performed a force regen of dpf as it was so clogged that the car went into limp mode (blinking glow plugs). Today the particulate filter error poped up again. In the meantime I've replaced a faulty thermostat and throttle body. The original throttle had worn gears frobably from too much carbon deposits. I've taken a look inside the intake and it is not looking that great. The hole that comes from egr is clogged and is only about 1cm in diameter. I assumed that was the reason why the dpf got clogged the first time. If I recall correctly we tested egr when we were forcing a regen and it could be heard it was moving.
Tl:dr
As said today dpf error poped up and I'm thinking of guting it, block the egr, clean the intake manifold and remove the swirl flaps while Im at it.
Dpf shouldn't be a problem. Open, remove internals and weld it back.
For swirl flaps I'll use a kit to delete them
The question is what should I do with egr? Is blocking of egr enough or egr cooler and other componeents need to be removed as well? Deleting it from ecu is in plan as well as a tuning.
