Airflow sensors

The amount of air entering your engine is a  mesaurable value.
This  undertaken either by a moving vane air sensor or more commonly a MAF or mass airflow unit.
The early MAFs were literally a  heated wire,the amount of air  was detected by the level of current needed to maintain the wires temperature.
All a bit hit and miss and prone to a lot of failures. Todays MAFs use thin film technology giving far quicker responses to changing air flow conditions

Full basic health check

how well is your engine running?
good bad,hard to start either hot or cold.
Starting issues are often the sign of  deeper issues developing,way before your engine  fault light appears.In  fact it may never illuminate and still the car will strand you.

A basic check is via the exhaust using a pulse sensor,and no bonnet lifting even needed

Coil on plugs

These are way better than traditional caps and spark plug leads but,the continuous heat soak buried in the engine takes its toll on them.
Cheap ones are the worst culprits,and they can fail without warning
we recommend replacement of them all at 30 000 miles to avoid that

Snap secondary testing

In a steady state engine running condition the ecu assumes full control.
A snap test  allows issues with certain components to reveal them selves.
As a subject its advanced and powerful one we will be entering in much more detail

fuel filters

Fuel filters are a vital part for regular maintenance.
A clogged or partially clogged  wil put a lot of strain on your fuel pimp causing it to fail.
