annoying squeal/squeak on a 06 plate Gti

Evening all,

It’s one of those strange noise threads again!

While driving along without touching the brakes I get what sounds like some brake squeal which chirps for a couple of seconds and goes away.  Generally a slight turn to the right or left can make it happen more often and when I let off the throttle it also seems to occur more.  It also only happens after ~7 miles, not from cold

Thinking it was the brakes, for the sake of 30 quid I rebuilt the front calipers seals, guides etc and found it had a rear sticky caliper which I have replaced but still the noise!
It doesn’t seem to do it on the motorway but does do it at 50-60 or lower speeds and sometimes I swear I can hear a faint continual sqeak.
It’s a rotary squeal not a momentary squeak which is why I have ruled out suspension etc but it’s starting to get quite annoying!

Anyone got any ideas on how to diagnose what it is?


Cheers
Dan

oh, the only additional thing is that it started soon after I replaced the CV boot, whole drivers side shaft came out etc

alternator clutch pulley checked - works fine, aux belt looks good and seems to be at right tension

its not the 'birds in my engine' cambelt tensioner noise and is intermittent

My Mrs has what sounds like the same noise on her scirocco and it's annoying as hell but don't know for sure what it is

Could be a lightly sticking caliper
