Hi folks I have a 2017 Eco-Diesel that's GDE tuned and runs great, but I just have one concern - it has a fairly loud tick or knock when cold, which gradually quiets down and when it's warm it doesn't sound abnormal - actually pretty quiet for a diesel. I've never had a diesel before - Is it normal for them to run noisy like this when cold? I still have some warranty coverage on the drivetrain as I'm at 61,000 Km so if this is abnormal I should get it checked out before the warranty runs out, but I don't want the dealership touching it if it isn't necessary as I'm afraid they may flash the ECU and I'll lose my tune..... Also I just changed the oil and had an analysis of the old oil done by Wearcheck - they said everything was normal - "Metal levels are typical for a new component breaking in". Any thoughts?
