BMW E90 Tensioner and Idler

aydan9879 · 04-27-2018, 08:50 AM

Hi all,

My BMW E90 320D 2008 has a slight squealing sound coming from the engine. Yes it's a diesel, but you can hear the noise coming from a particular part of the engine bay.

I've been advised by a local mechanic I may need to replace the fan belt tensioner and idler/pulley.

BMW Peter Vardy are charging £150 for both parts, is there anywhere else to purchase these two parts from? And has anyone else experienced a similar problem?

Cheers

This is a common problem on the n5x series engines, and I would guess a similar tensioner was used on the diesel.

You can part the parts kit from a number of different vendors. This is the parts kit for the gas engine, you'll need to input your make/model/year to get the right parts.
