Hi Guys,
I randomly decided to plug in the MB Carsoft tool into the car and ran through the diagnostics.
It showed the following two fault codes as stored:
I have noticed it drinking a bit more fuel than usual (it's not fuel efficient anyways) and a many weeks ago I do recall seeing the check engine light which extinguished itself the following day. I also tried replacing the fuel filter a few weeks back but gave up as I couldn't remove the Clic-R clips and thought maybe the slight increase in fuel consumption was perhaps down to a slightly loose fuel line in the fuel filter after my failed attempt to remove the clip. This could of course have nothing to do with it and is just pure speculation on my part, but thought it's worth a mention in case.
Would be grateful for any advice as to what the issue may be.
Many thanks
