A Genuinely Important Point Worth Knowing Before Attempting a Motorway "Regen" — Toyota Auris Exhaust System
If your diesel's engine management light has already illuminated, this is genuinely important to know before spending time and fuel on a hard motorway run: a proper regeneration cycle generally can't occur while the engine management light is on, since it indicates an underlying fault the ECU needs resolved first. Attempting to "drive it out" at this stage is often genuinely futile — the fault causing the light needs diagnosing and fixing before regeneration can succeed.
It's also worth knowing that a recurring EGR-related fault code that returns despite cleaning points toward the valve needing replacement rather than further cleaning.
Toyota Auris Exhaust System: The Part That Announces Its Own Problems
On the Toyota Auris, this is one of the few parts where your ears will catch a problem before your eyes do — a new rattle, a drone, noise that simply wasn't there a week ago. That's a genuine advantage, since it gives you an early warning most other faults don't offer.

Toyota Auris Exhaust System: What It Does
On the Toyota Auris, burnt gases leave the engine through the exhaust system, which quiets them via the silencer and treats emissions through a catalytic converter and particulate filter before anything exits the tailpipe. Petrol and diesel versions frequently use entirely different systems, since their emissions treatment needs aren't the same.
