Warnmeldung Stop Bremsflüssigkeitsstand | Posts 16+

Hi,

Could the float be shorting against something? Perhaps a wire is frayed (which is not unlikely given your tight installation) and occasionally touching the body of the car, which acts as ground.

You might temporarily wrap the wiring harness in potentially problematic areas with electrical tape to rule out this issue.

Regards,
Sure.

Here is the translation of the text from German to English:

"Guste" means "gust" in English. It can also be used as a verb, meaning "to gust."

Hello,
It turned out that a filter screen, which holds the float tube in place and prevents it from slipping, had simply been forgotten to be reinstalled by ATU (a German automotive service chain).
Unfortunately, I don't know why they expanded it. According to the Volkswagen master technician, it's also not necessary when changing the brake fluid.
Since the filter is not available as a separate part, the entire brake fluid reservoir was replaced (as that's where the part is located).
All things considered, the whole experience cost a hefty €141.
Now, ATU has to pay the bill.

Best regards, Jürgen.

Hi Jürgen, thanks so much for the feedback!

Even though I'm going to stick my neck out here...

I believe that the repair manuals from (at least) Audi stated:

Do not remove the sieve under any circumstances!

I've never tried it, but I've at least fiddled with it and I think it might even be permanently integrated into the container.

No wonder a new container was needed...

Once again, there's a reason why I always end up being wrong about ATU...

Okay, here's a completely different question:
"I also struggled with that filter last week. I was changing the brake fluid and wanted to extract as much of the old fluid as possible without introducing any air into the system, so that I would have the least amount of mixing between old and new fluid. Unfortunately, I failed to remove the filter properly, and then I forced as much of the old fluid as possible through the bleed valve before adding the new fluid. How do they do it at a VW workshop? Do they just use a pressure filler and then briefly open the valves? If so, that would mean quite a bit of old fluid is mixed in...? Because without removing the filter, you might only be able to extract half of the fluid from the reservoir."
The old Jettas never had anything like that.

Dirk.

Okay, so that company also removed this filter from my vehicle. I made sure it went back in, but it's best to supervise them while they're working. I didn't know that it wasn't supposed to come out at all. Anyway, I had already decided not to go there anymore. Once, I took my Golf to them for an axle boot replacement and headlight adjustment. The headlights were adjusted way too high, and the screws on the driveshaft (on the transmission side) could be unscrewed by hand! That's quite dangerous in a 174 hp Golf III! The TÜV inspector was very friendly, and even though he expressed his displeasure with them, he still gave me the approval sticker.

When changing brake fluid, you don't need to drain the old fluid first. You pump in new fluid from the top while bleeding from the furthest wheel. You keep pumping until the color changes and you're sure it's fresh fluid. You work your way forward like that. Then all the old fluid is out, or at least 99% of it, which is sufficient. According to VW specifications, I believe the amount of new fluid needed is about 2 liters.

"Now that I have my own brake fluid exchange device, I always replace the clutch fluid as well. However, workshops usually don't do that. In my opinion, there's also fluid in the clutch system that ages over time. I also use a little more than 2 liters of fluid to be on the safe side. It's not extremely expensive."
