Mercedes W205 Deseil Rattle From Cold Start
 

Hi I have a W205 2017 Deseil Mercedes Benz C Class OM651 Engine , and started to hear load rattleing type sound on cold start most morning etc , the weather has turned cold outside now so was thinking timing chain or just oil pressure builiding up , Ive recently had oil change and filter but was also hearing before that Ive used Castrol 5W-30 Mag Prof A5 And Mann Filter ,any advise welcome :-)
