Hello everyone.
I have a question regarding exhaust gas backpressure, and what is an 'within tolerance' reading.
Using BMWhat app, no error codes are thrown. Car seems to regenerate as expected, coolant getting to 91 or so during normal driving. So far so good.
However, exhaust gas backpressure readings, there are two options in the app, one is upstream of dpf, other is before dpf. Both are reading about the same, fairly consistent at around 1000 hPa (whatever hPa is)
And there lies my question, anyone in the know, know if that sort of reading is ok??
Many thanks for any help
Garry
