Me not happy.
Less than 900 km after the forced regeneration of the DPF and a bath of fresh oil, the oil level is already too high - almost as high as it was before the last service and before the fresh oil got put in !
Oil analysis after a mere 3300 km / 2000 miles shows 6.5% oil dilution.
So that isn't the cause of the rising oil level.
It's either been overfilled, or hasn't been drained properly before being refilled, twice in a row !
There'll have to be some answers ....
Proper used oil drainage from these 1.6HDi engines is apparently crucial, according to the C4owners.org FAQ .

Same engines, same troubles.
