paul.h Posted July 4, 2022 Share Posted July 4, 2022 I would check it with a Citroen dealer since I suspect normally it might suck in air if the dipstick is pulled out and then possibly give a fault code. How many miles has it done, it might be the piston rings are worn. When I had a turbo fail smoke blew out of the oil filler cap and the exhaust smoked on a petrol Saab. A quick search suggests it is not normal. Quote Link to comment Share on other sites More sharing options...
paul.h Posted July 5, 2022 Share Posted July 5, 2022 I should have asked what year and model is the car. If it is a 1.6 hdi these have a reputation for turbo failures and if not found early can lead to engine damage needing a new engine. These need annual (or 12k miles if sooner) oil/filter changes with the Citroen recommended oil and filter. Quote Link to comment Share on other sites More sharing options...
