Have had car for about 5yrs with no problems. Oil pressure warning light has started to come on and it gets very insistent that I must stop etc. It may disappear for a while but then can reappear without warning. Oil and filter was changed as service was due shortly but light still came on , engine ok, took it to a Peugeot/citroen independent specialist but the diagnostics showed no fault and no logged faults. Replaced the oil pressure switch but the problem has returned. Anyone had a similar problem.

Anyone had a similar problem?
Probably everyone who owns one of these!
Carbon build up blocks the internal oil feed system.
Usually resulting in a failed turbo.
Which will happen to you if you keep running it.
You could try several oil flushing treatment but the best course is strip and clean the internal of the engine.
And I normally remove the injectors and re cut the seats.
