2005 Citroen C5 chattering noice at startup

Running Rough, Starting & Power Loss
When I start the car in the morning there is a chattering noice for about 2 sec.Sounds like it is from the top of the engine. Sound dissapears after 2 sec. No crank-bearing-noice under load. Sounds somtimes less sometimes more, but after the first start the noice is gone. Have had 120000km service but the rep found nothing.Engine have no power loss. Oil is ok. Has been gradual coming on over time. Have prescribed oil in the engine, and have also tried STP to test if it is oil-dencity related, but seems not to be. Can this be a problem with the oil-driven intake camshaft advance mecanism? Have changed both controlvalves, but bo improvement. Have talked to Citroen consumer assist here in Sweden and 3-4 shops but no one can advice!
Quite distrot!!
