My Vauxhall Zafira 1.7 cdti ecoflex engine, cleaning the Exhaust Gas Re-circulation valve.
Over time this gets clogged up with carbon/exhaust deposits and becomes sticky. If left too long it will jam either open or closed and reduce engine performance.
The EGR is there to re-burn exhaust gases to reduce noxious gasses being emitted from the exhaust.
This video I show how to remove and clean it on the 1.7 diesel A17DTJ engine.
