HDi consumption problem

Post by 406 V6 »

Hi!
Guys, i took my C5 some 4 weeks/2000kms ago to the 25000kms overhaul at the importer.
I asked them to upgrade the software, but i don't trust them...
Anyhow, i used to make around 8.8L/100kms, virtually the value didn't change. Only once i made 9L/100kms.
As it came i noticed it a bit more torquey and powerfull. Also, the consumption is now 9.5L/100kms!
Could it be a shot MAF sensor?
Oil and air filter changed along with the oil.
I have an OBD interface around and will try to plug it in to see if the MAF values change.
Thanks!
