Hi all.

Yesterday I had a new clutch kit, flywheel and slave cylinder fitted to my 2016 2.0 TDI 190.

Took a day as the first flywheel they were given was the wrong one. Apparently the 190 has an updated one.

Anyway, they got the right one. It was all fitted. They rang me and said it test drove ok and was ready to collect. I duly did that and I drove it home. The pedal felt slightly soft. But worked ok.

This morning I got in it to come to work and pressed the clutch down, started the engine lifted my foot off the clutch and the pedal came up slightly but not fully. I pulled it up with my foot. Did this 2 or 3 times and the pedal started to work. Still felt a bit soft.

Rang the garage and they said it could be air. Drive it today and see how it goes, any issues get back in touch.

So I've driven it to work. Got along the motor way and pulled up to some lights once off the motorway, pushed the clutch down, into neutral and the clutch was slow to come back up but it did. Pumped the pedal a few times and it felt more firm and came up ok.

I've just tested it now I'm on lunch and again it felt soft but it came up ok. I have pumped it a few times and it is behaving better again.

So, could that be air, or some form of leak? I can't see anything on the floor under the car. Im a bit worried as we go away tomorrow towing our caravan. I may ring them in the morning see if they can squeeze it in before we leave.

Anyone had an issue like this before?

Thanks

Adrian.

Pedal feel and response improving when it is pumped would strongly suggest air in hydraulic system to me. Does the fluid level in the master cylinder look as if it has dropped since the repair?

Nu it does not. Am I right in saying it shares the brake fluid?

yes.

I checked that yesterday. It is a bit awkward to see. But I'm pretty certain it's topped up.

The fluid level won’t necessarily drop if there’s air in the system. Just get it back to the “garage” ASAP - they should’ve just told you to do that. Oddly, it’s not going to become sentient and resolve itself.

I recently got a device, it's actually a hose with a non-return valve, it's aluminum and after each use you have to disassemble and wash it, but it works great, one side is put on the bleeder valve and fixed with a string and the other in a container.

you pump the brake - or clutch until the bubbles stop coming out. you tighten the bleeder and that's it. all together not even 5€
