Question Name/PartNO for this part?

Full of questions i am..

Under the hood there is some kind of black plastic cover over the left and right suspension tower, my car seem to be missing those.
Can anyone identify a partnumber for them so i can buy new ones.


NOT my car on the images (mine never gets this dirty)

BTW
I just replaced my DPF pressure sensor for the third time ( in 4years) cause the car started acting up again.
Symptoms was Limp Home mode, High rpm before changing gear and felt out of breath. Sometimes a CEL. It was possible so solve the problem temporary by shutting down and restarting the car but the problem occurred more and more often.
so i replaced the sensor took care of the problem fully.

Does anyone know why this breaks so often?

Limp mode more important than plastic covers. I don't have these tower caps either.

Are you positive the DPF sensor triggers this ?

High back-pressure is from plugged up dirty DPF.

built to deliver

Some Limp-modes can disappear with a quick restarts. Then repeat sometimes later.

Troubleshooting is not easy - At least it shows up like clockwork so you can gather live data.

These systems are designed with premium issues.
