5 days later and still no noise. Appears the gasket was the issue. Anyone know what the vacuum should be?

So I've changed out the oil separator with a genuine one and found the gasket was leaking, as evidenced by the oil leaking around it. Comparing them again I can see the orifice for the genuine one is much smaller, so it's plausible this was causing an issue. Test drive has resulted in no more squealing! However, I'm not convinced I've resolved the cause of the high vacuum, as the cap is still being held on tight, simply resolved the symptom. Anyone know what vacuum I should be reading on this engine? I have a vacuum gauge I can hook up to check it.

We're thinking along the same lines here. I've examined the system as far as I can without removing major items. All pipes are clear and the NRV or check valves work as intended. I'm going to order a genuine oil separator and inspect the rest of the system whilst I'm switching that over on my next weekend 04E103464AM I think is the one I need.

So clutch/pressure plate and release bearing changed and still making the noise... However, the bloke at the garage noticed the noise stops when you take the oil cap off the engine! Looking into this further if you block the pcv pipe were it goes into the air filter box the noise gets louder so he's on to something here. I switched the PCV valve with the one from the wife's 1.0 seat (advantages of having 2 vag cars) and no difference. The oil separator is only a few months old but I cheaped out and bought a pattern part. It's only a baffle maze with no diaphragm which I compared with the previous so I'm reluctant to think that's it. Will have to check the rest of the breathing system tomorrow. Hoping it's not the RMS as the gearbox was just off..

I'm hoping it's a release bearing as it's far easier to get to than the input shaft, which is a gubbins out jobby. I'm going to get a clutch kit and have a look whilst the box is off. Do you know if these are DMF? Cheers

In the video I go from: Clutch not pressed Clutch half pressed Clutch fully pressed Repeat. You can hear the noise changing at each stage.

Ok so I've run the car from cold and just let it idle untill the noise appeared. At around 25mins it lightly appeared. Then 20mins after it was at full squeal. The strange part? The clutch pedal is affecting it now?? When half pressed it changes the squeal slightly, then fully pressed it goes away? Tried a few times with same results. So now I'm thinking input bearing? https://youtube.com/shorts/BZBu2Krn44M?si=92dvbLsgEfHXVi4W

Can't say with certainty, but it started the same time as the other squeal so assuming it's the same. Lasts for about a second, also coming from the bell housing area. Sounds louder under the engine rather than on top. Also no lights on the dashboard if that helps. Thanks

Hi all, I've been having an issue with a loud squealing/chirping noise coming from the bell housing. Car is 2015 1.2 TSI 110 cjzd (belt driven) 107k miles Symptoms: It's never present when cold, only after driving for 10ish mins. It appears to be coming from the bell housing. Only present when idle or cruising at around 30mph. If I blip the throttle it will go away untill revs drop back down. Pressing in clutch makes no difference. When I turn the engine off you can hear a continuous squeal that's slows to nothing with the engine stopping. I'm going to try get a video today. Any suggestions? I'm looking to book it in for a clutch change, it's still on the original one. Appreciate it

Appreciate the reply, This is what I'm finding as well. I'm guessing the 1.2 tsi 110 rapid exhaust would also fit ? The original one has lasted me 10 years/100k miles so I guess if I go dealer I'll have that peace of mind knowing I "should" get that again.

Evening all, Annoyingly my exhaust fell off on the drive home from work today, it's a 1.2 tsi 110 Toledo. Does anyone have a recommendation on where to get a good replacement from the cat back? Thanks,

Hi all, I am currently tracing a parasitic drain in my Fabia MK2. Ammeter shows a drain of 159mA, which drops to 45mA when fuse 20 (r/h drive - 4th fuse in from the right, on the top row, on the smaller micro fuses) is pulled. My research suggests this fuse is one of many ECU fuses. Is there anyone that confirm that the fuse is for the ECU and help point me in the right direct of what part of the ecu it may connect to? Thanks for your help EDIT - Car is a 2008 fabia 3 mk2, 1.6 petrol, automatic.
