Hi all
i have 2010 a4 2.0 tdi caga engine 136hp at low rpm im getting what sounds like the drive shaft bearings cracking but its nothing to do with the drive the sound is lower pitched and seems to only happen below 2000 rpm .At first i though it was a kind of pinking noise as it happens in every gear when the engine is under load but its hard to describe . i know it will be due a clutch soon as the pedal is a bit high and also its due a timing belt replacement but as i am new to the 2.0 tdi i was just wondering if anyone had any idea as to what could be causing the noise or a way to check and rule out other possibilitys .
kind regards graham
