Get it checked for the fault code(s), the fault could be a simple fix like an 02 sensor or dirty maff, but there are various reasons why the eml comes on, you could get a scanner off ebay/amazon and check for the codes as long as the scanner has the JOBD protocol

I bought a scanner but it didn’t actually give me the exact problem.

it could of been vacuum leak , o2 sensor or maf .

I took a chance on a second hand maf on eBay for £30 , took 5 minutes to fit , no more engine light .

might be worth removing the maf sensor and giving it a proper clean , I reckon that would actually of fixed my problem, no need to buy a new one .

Mass Air Flow sensor. It's just downstream of the air filter.
