Hi,
I manage to get some scans on my audi, problem is that: Glow plug(intermitent light) and dpf symbol on dash. Cars runs fine, can be rev up to 5k with no problem, but dpf does not regenerate anymore, the g450 was replace with one OE, but same readings. Dpf was cleaner with hot air, also with chemicals, very clean was. Also egr valve opening is always 100%. this opening shouldn't be 100% just when I press accelerator pedal ? This can cause the dpf not to regenerate? Also soot is around 66% and goes up. Already 4 regen failed. Also pre-dpf temperatura rarely gets over 350 *celsius. No other dtcs, just p2002.
This car has egr cooler ? Could be this my problem ? How to test it ?
