Hey,
Multiple malfunction lights but 1 code
Dsc malfunction
Scbs malfunction
Tpms malfunction
Eml on
P0472 exhaust pressure a circuit low, Ive already replaced the sensor and no change
Any ideas ??
The car is running ok and if anything I had my brakes replaced 2 days ago

Some people report destruction of the ABS cables. So you could return to the garage and ask them to have a look.

Could you explain how a faulty ABS cable would cause these issues? I'm having almost identical symptoms to the OP but I can't wrap my head around an ABS fault causing an exhaust pressure warning. Thanks

Not sure about the exhaust pressure warning but this might possibly explain the other lights:-
"The indirect method works with the car's ABS and stability control sensors to read the speed of each wheel, and report when one is consistently faster, meaning it is low on air."
As far as I am aware, this is the method used by Mazda.

Sorry, I should have put that this relates to the different methods for TPMS

Thanks for the reply. I managed to get to the bottom of the issue on my car, luckily it had nothing to do with the brakes for me it was just a faulty/blocked exhaust pressure sensor. I wrote more about the issue here:
