🔧 Nissan Qashqai in for a full health check to investigate an EML light and lack of power.

On inspection, we found the main intake pipe had split just after the MAF sensor. This was causing the loss of power and also triggering a MAF sensor fault code on the diagnostics.

A new intake pipe has been ordered, and once fitted, this Qashqai should be back on the road and running exactly as it should by the end of the weekend. 👌👌
