Your particulate filter is experiencing an issue; this could mean it is blocked or that it needs replacing entirely.

Front Brakes

Your front brakes are approaching the wear limit and should be replaced. SRN Motor Services will also assess brake disks to ensure safety.


Every time your oil is serviced, you should get your microfilter / pollen filter replaced.
