Vauxhall astra L diesel 2022 model timing belt interval and air filter and diesel filter
Our answer:
Hi Derek,
The air filter and diesel filter should be changed at least every 60,000km or four years - whichever comes first. The timing belt should be changed at least every 180,000km or 10 years - again, whichever comes first.
