Manual or auto?

What's the condition of the battery? Has it been tested?

Yes, it's doing a regen.

Scan it for codes. Get the battery checked. Is it the original battery?

What's the error message?

Which media system do you have?

What engine do you have? The timing belt advisory replacement has been changed. It's no longer 5 years. There are threads on here about it. There is only one washer pump which does both ends. This is one of them.

Power steering is electric, no fluid needed.

Suggest you get it scanned and see what the error codes are.

Does it do it when stationary and you rev the engine and let it fall to idle?

Do you have an Octavia? I'm guessing not. The instructions given in the link are completely false.

If you search Hollowmanvid on youtube you may find the clip you're looking for.

Try and find a Briskoda member local to you who can scan for fault codes.

Glow plugs?

Such a simple job. Mine was blocked for a few years. A few days soaking in vinegar did the trick for me.
