Doctor Monster
Leave it with me. I'll have a word with it.
Doctor Monster is the repair-first mindset: diagnose properly, prove the fault, clean or repair where possible, and only replace parts when the evidence says so.
"Leave it with me. I'll have a word with it."

Ask Doctor Monster
Choose a symptom. Get the first diagnosis steer.
Doctor Monster recommendations for the common faults that make diesel owners panic. This does not replace a proper workshop diagnosis, but it gets the next step clear.
DPF warning lights need pressure readings, sensor checks and root-cause diagnosis. Do not keep forcing regens or replacing parts blindly.

Check pressure, sensors and root cause before cleaning.

Inspect boost leaks, actuator movement and bearing wear.
Check injectors, turbo health, boost leaks and oil contamination.
Test injectors properly so DPF issues do not return.
