Hi All,

I’ve got a very occasional metallic squealing/chirping noise. I think it’s coming from the clutch as I’ve only experienced it making the noise in 1st gear when pulling away, only makes the noise at biting point. (Doesn’t make the noise in neutral and doesn’t make the noise when the pedal is fully depressed)

Just wanted to get some ideas for all the possibilities that would be causing this noise. This noise has been going on for a few months now and doesn’t seem to have gotten any worse or better. What action would you take if it was your car? Thanks in advance

Golf MK7 1.6 TDI 5speed

Age of the vehicle?
Mileage?
Has it had a new clutch at any point in its life?

High frequency metallic squeal from the clutch generally indicates release bearing, however I would expect it to do it in neutral and in all gears when the clutch pedal is pressed so it'll probably develop in time..

Eventually you're in for a new clutch kit including the slave cylinder which is probably integral with the release bearing and possibly the flywheel depending on what is found when it's inspected.

In the mean time the release bearing will cause increased wear to the fingers of the diaphragm springs on the pressure plate, but that is replaced as part of the clutch kit so no worries there. If it's left to collapse entirely you might find the clutch doesn't clear properly which will start to give the gearbox a hard time. You'll probably notice a crunch on reverse first, but the bearing will be screaming embarrassingly by this point!

If left until it goes bang potentially the release bearing and/or the fingers on the drive plate will destroy each other & you'll need a recovery.

Done a couple on other cars, the bearing was in bits, the ends of the clutch fingers had either broken away on the wear area or were nicely twisted & one had damaged the release lever for good measure.

2014 just over 50k miles, and not that I’m aware of.

Thankyou for your detailed responses, very helpful. How long would you expect it to take for the release bearing to go from a slight chirp to failure?

That's a 'how long is a piece of string' question. Impossible to predict.

FWIW the clutch on my youngest's 2.0 Pug 307 started to squeal - he told me it had been doing it for a couple of weeks - & I had it done by a mechanic friend as I was too busy to fit it in. When he took the gearbox off the release bearing promptly fell apart. IIRC around 70k.

It can also depend on how the vehicle is driven. Some years I fitted a new clutch to my wife's 205 which was then passed onto my eldest. The clutch went - as in ends of fingers worn through which then trashed the release bearing. Had done around 15k miles. She habitually drives with her foot resting on the clutch pedal & no amount of telling has ever made any difference.

Without having heard it and assuming average use I'd guess we're talking a thousand miles or more rather than a hundred. A winter will probably finish it off if it lasts that long.

Feel for vibration through the clutch pedal when you depress it

Also if the gearbox starts feeling stiff when engaging gears or crunching into reverse it is time to get it fixed before you damage the synchros.

I predict you will replace it out of embarrassment due to the awful noise before it actually strands you.

Also we need second opinions in this thread, because it's odd that it only does it in 1st gear... makes me consider whether it could be a belt noise.

I had a shed Saxo which I ended up putting a clutch kit in and then a shed Peugeot 206 which I didn't like as much. The Peugeot I just continued to drive as the bite point got lower and lower. It got worse in steps as the fingers of the springs got machined to nothing and pinged off. One day I got in it and the clutch pedal was completely ineffective. I shunted it off the driveway in 1st gear and proceeded directly to the scrap yard. It was a pretty stressful drive but I did pass 'Go' and collect a very generous £165 for my troubles. Fortunately the battery and starter motor in the car were strong.

Thanks again for all the detail, definitely welcoming second opinions as I’m hoping for a cheaper fix than a clutch job but I kind of think it’s enevitable at this point!

Talking of the biting point lowering, I can’t remember if it was lower or higher but I have noticed the biting point moving, only for one clutch press and it’s only happened a couple of times and not recently either. Not sure if my car has a self adjusting clutch or not
