German term

kaudern

German to English Tech/Engineering Automotive / Cars & Trucks car engines
Anti-Kauder-Funktion - just in a list related to VW cars.

It refers to a noise coming from a car engine.

For example below, from: https://community.dieselschrauber.org/viewtopic.php?p=208003...

Aber unser BLS kaudert nicht, er dröhnt nur etwas, wenn man ihn so richtig schaffen lässt, ihn also knapp über ZMS-Rubbel-Drehzahl drehen lässt und dann volles Drehmoment fordert.

There are a few other references from similar forums. I've tried "rattle" or "hum", but I don't think either of them really capture it. And it sounds as if it is an accepted term to refer to precisely this noise. Any mechanics out there? Or with better research skills?!
Thanks

turbo whistle

See links and google. Alternatives are "turbocharger whistling" and the like. "Whining" is also used, but my feeling was that "whistling" is the more common term. It is basically excess air pressure from the turbocharger that flows back and forth in these turbo hoses.

You are right! Perhaps its a spelling mistake and "zaudern" (hesitate / falter / waver) is meant, which does seem to fit better.

Thanks Alexander. Yes, like Kauderwelsch, that's the only time I've heard "kauder" - but in this context I'm not sure.

to swish

"Talking gibberish" obviously doesn't work for an engine noise; "chattering" might be possible but I don't think that's the noise that is meant here. These two links seem to refer to the same noise. It's obviously to do with an odd air flow and it seems like it's a sort of grinding/swishing/scraping noise. There's almost certainly no set term for it, as all the references seem to be onomatopoeic.
Note from asker:
Thanks Tim - great references. Also good to hear that there doesn't seem to be a fixed term (but also disappointing!). Swish is my favourite so far - even though I would expect something like "zischen" or "sausen"...and "kaudern" is clearly a term often used on car forums/by mechanics.
Peer comment(s):

agree Vere Barzilai : The front brake affects directly the tire of the front wheel with a rubber-pad, whereby a characteristic grinding noise comes up.

hissing / rumbling

Ich fand eine technische Erklärung: "Kaudern ist laut Audi ein Strömungsgeräusch hat fast jeder 1.9/2.0 TDI Motor . Beim Beschleunigen wird knapp oberhalb von ca. 2000 U/min der maximale Ladedruck erreicht. Bei Drehzahlabfall / Lastwechsel des Motors durch Gaswegnahme entsteht nun ein Rückstau der angesaugten Ladeluft und somit eine Rückströmung der Luftsäule. Dieses Strömungsgeräusch (kaudern) ist nur für kurze Zeit zu hören.
So this is a short, "rumbling" / "hissing" / "harrumphing" noise in the air-intake tube, when you quickly reduce load to a much smaller value, e.g. switching a gear.
Example sentence:

bei Gaswegnahme bzw Lastwechsel höre ich ein unschönes Kaudern.
