Recently bought an Audi A4 2.0 TDI 170 Quattro Manual on an 09 plate. The car has done 164k miles so it’s not exactly low however Iv had an issue since, when the car is both cold and warm it shakes on idle.

There is no smoke, loss of power or warning lights, in fact it moves quick. However it shakes a little and sometimes feels like a shudder, anyone have any idea what it could be?

Thanks

Mass airflow sensor maybe 

That happened to me just before the timing chain went on me, best get it looked at….if you have breakdown cover get them out.

Hello Zeeshan,

Does depressing the clutch when idling, make any different to the shuddering? 
Kind regards,

Gareth. 

Check your timing belt and make sure its in good condition, and does it shudder when you raise your clutch pedal

It could be an issue with your mass airflow sensor or maybe something else with your fuel air flow mixture set up 

Well, all rather academic now, since the original poster hasn’t returned to the forum since he placed the post.

This is the thing, I did try seeing what happens if I press the clutch up and down as I was trying to pin it down to being the flywheel.. it didn’t make any difference

The alternator pulley is starting to make a noise now and after taking a look it seems the belt around it has seen better days too
