Hey guys, I have a 325D M57 Engine and I have noticed that my car makes a very small Squeaking sound, like of a timing belt, but it only lasts for like less than a second when I start the engine.

Like I click the button, the engine cranks and when it starts I hear that sound which is literally less than a second and then the engine runs great.

The car has 180k km, timing chain has been changed by the previous owner at 160k.

My mechanic only told me that the glow plugs need changing, but he told me to change them in 2-3 months since it's pretty hot these days anyways.

Any ideas?

Nobody?

Could be pully's? Or if belt related fluid on it? Could be many things. Sorry I can't be more specific.

On a side note, you need to get your glow plugs fixed if you have DPF. It won't regen if there are glow plug faults...
