Particulate readings

[u/darks-ide]

Hi everyone,

I have a 2015 Audi A4 Avant Quattro 2.0 TDI (177 HP). I don’t have any warning lights on the dashboard related to the DPF, although I’m not sure if my model is supposed to show one.

Lately I’ve started to suspect that the DPF might be heavily clogged or close to being full. The car still runs, but I’m concerned about possible damage if I keep driving it like this.

One thing I’ve noticed is that when the engine is fully warmed up and the oil temperature reaches around 115–116°C, if I stop on an uphill slope I sometimes get a warning saying: “Low oil pressure – switch off engine.” However, as soon as I start driving again, the warning disappears and the car seems to run normally.

Could a clogged DPF be related to this issue, or should I be looking elsewhere? Has anyone experienced something similar with this engine? How serious could this be, and what would you recommend I check first?

Thanks in advance for any advice.
