Hi guys, please help me, I can not figure that one out... :thinking:

Yesterday, I was on my way home, driving in 50 km/hr zone and noticed weird metal like clinking/rattling noise, its somewhat similar to brakes. Only happens on 2nd gears and higher, does not appear on neutral or while van is standing still.

Driving 30kmhr+ between 1400-2100rpm is the only time when it appears.

Only when you apply the accelerator, and remains for 0.5 of a second upon release.

The van is late 2012 316 auto and is still pretty much brand new.

Any help will be appreciated :thumbup:

Thanks:
Arthur

Does it happen when the gas pedal is kind of being middle positon... maybe you are apply just a few PSI of boost, but not full load? sound go away when you press full on, or release entirely?

I'm going to call it an exhaust leak. I'm not familiar with the model, but if it has a metal gasket anywhere in the exhaust system pre-turbo (manifold to head, manifold to turbo, manifold to EGR, etc) a leak will cause the gasket to vibrate against the joint and create a very loud metallic screeching sound under load.

Just look for black soot telltale signs around all your manifold joins. Or spray some soapy water around all the joins when cold, you should see bubbles where the leak is.

Mine makes the same noise. I've traced it down to turbo vanes.

I have the same noise on a 2013 since brand new. I've accepted it as normal

Get it back into the dealer, it's under warranty.
