Good evening all. I'm having an issue with my clutch not holding pressure. Symptoms such as creeping forward in first gear after a minute or 2 of having clutch fully down and biting point being right at the bottom. Also if holding pedal down for a long time it doesn't always spring right back up without pumping it. I'm going to try and bleed it at the weekend but I suspect I may need to replace the slave cylinder as well.

I looked at my boot sticker and it has a GSH gearbox code. My mk1 fabia is a 1.2 htp. 

I was looking to see where I could source the part. The Sachs one that came up on euro parts had fitment detail of MQ 200 but doesn't mention GSH code. So my question is the GSH gearbox a varient of the MQ 200 as couldn't see a slave cylinder specifically for this gearbox code.

If this doesn't fix the issue I'm guessing master cylinder could be at fault. Car has only done 56k.

Thanks in advance 😁

https://skoda.7zap.com/en/cz/fabia/fab/2006-453/7/721-721025/#30  #30 but you'll need to find the PR code as there are 3 versions listed, the PR code will be on a sticker in the boot (spare wheel area normally) or in the service book if you have it 

Pretty sure it's the 6QE721261 number you need, or aftermarket equivalent.

PR=0EM means MQ200 box. That code isn't on the sticker of our very similar car, but is in the full car data of it.

corrected part number 'anagram'

I think all the small petrol engines have the same slave, even my 2.0 looks the same as that, I replaced master and slave on my 1.4 16V and the parts were generic, I seem to remember using Sachs parts and I needed an eezibleed to get all the air out.

Thanks guys there is no mention of MQ 200 on my sticker. Also Euro parts don't list part numbers or aftermarket equilvalent codes other than their own product code... https://www.eurocarparts.com/p/sachs-clutch-slave-cylinder-137440240

 

Nothing is ever straight forward is it 😂

Thanks yeah I have a pressure bleed kit. Even that confused me as says don't exceed 20psi so I assume I need to deflate my tyre down from 30 before I use it? Previously used a hand vacuum pump but didn't have great results from it tbh and takes quite a lot of pumping 😁

Your problem sounds more like the master cylinder, unless you are losing fluid and/or can see fluid weeping from the slave cylinder I would concentrate on the master cylinder, seal wear in that can cause the problem you have without any fluid loss.

I didn't bother lowering the tyre pressure, I just connected it straight to the OSF tyre, I ignore all that sort of legal guff and make my own decisions about things.

Yeah I was thinking of trying the easiest things first. I've never done a master cylinder I assume it's a more long winded job has anyone ever done one at all?

Yes, I replaced both at the same time because they're plastic nonsense and would both have completed exactly the same number of cycles, if one had failed the other was about do the same. MTBF people.

Master was trickier to do.

On the Yeti yes, don't know if the Fabia is the same.

 

Not too difficult the 3rd or 4th time!!!!

 

 

I always think of MTBF whenever I read one of the frequent outpourings saying  the tamping wopple on my 4, 6, 8, 10, 12 year old Skoda with 40, 80, 120k miles surely should not have failed so early, it must have been a manufacturing fault and surely they are liable!

GSF appear to do slave cylinders for about half what that ECP one costs, e.g. this comes from an ebay search of the genuine part number:
