Title: Ticking Noise Issue
Post by: fsgti on July 17, 2022, 01:25:14 pm

Apologies if this is the wrong place, still relatively new to forum.

A ticking noise comes from the car whenever I am off the throttle and still in gear. As soon as I get back on the throttle (even if slightly) the noise goes away. If I remain off the throttle but switch to neutral and coast, the noise goes away also.

I suspected that it could have been the turbo wastegate fluttering initially but am not sure anymore after finding the noise goes away when I coast in neutral. Surely it should remain if it was turbo wastegate flutter.

Car is a 2007 MK5 GTI, BWA engine

Any ideas and suggestions are appreciated.

If it's on the driver's side, it could be the N80 evap purge valve resonanting in the carbon can.  Mine has made a quiet ticking noise for years, which comes and goes depending on throttle position at town speeds.  That is the only thing I can think of as it sounds very 'solednoidy'.  I only normally notice it around town because the noise bounces off walls etc.

Hmmm, will take a closer look.

Thanks

Does it make the noise when the engine is cold, or just when it's hot?

If the latter, it's probably something mechanical.  Hydraulic lifter lash, VVT noise, Chain noise etc.  Something of that nature.

It's definitely not the turbo.

Happens regardless of temperature the car is.

Better get it diagnosed at a garage then.  A "ticking noise" could literally be 1 of 100s parts on the engine.

If you trace it, be sure to report back!
