Pajerosport 3.2 4x4 Engine Light illuminate

[GavJacAML]

Hi My name is Gavin Horne,

We recently bought a Pajerosport 3.2 4x4 2010 with 235000km on the clock.
We currently faced the engine light illuminated and the garage had a look and cleared the airlock in the pipes.

After the airlock was removed light went off last week.

Today the engine Light illuminated again today.

is there maybe any advice why the light could be illuminating again.

Thanks Gavin
