Steuerkettenproblem beim 1,2l TSI noch aktuell? | Posts 16+

However, to be honest, I'm surprised that you decided on a chain drive even after your research.

Um... a car designed for women doesn't prioritize the engine as much as practical usability.
And after the Rapid Spaceback with automatic transmission was supposed to be available, the 1.4 TSI seemed like the relatively least bad option.

So, wir sehen ab, wie unser CAXA funktioniert. Wenn er uns mehr Probleme bereitet als Vorteile, wird meine bessere Hälfte wahrscheinlich bei der nächsten Autowahl mehr auf meine fachkundigen Ratschläge hören.

Okay, with currently around 1200 km on the odometer, the CAXA made some strange noises today during a partial start-up (stand time: about 3 hours, uphill with the DSG in P-position): a dark grinding or muffled knocking sound, occurring several times in a second-long interval, coming from the engine compartment.

Does anyone know this and have a possible explanation?

After we were home and had unloaded the car, the warm-up for the drive to the garage was completely uneventful.

Edit:
Oil level is in the maximum range.

....The warm start is usually silent. Only the cold start (really cold) is noticeable. It is characterized by a rattling sound, lasting approximately 2-4 seconds. Interestingly, not only TSI engines are affected, but also unloaded 3-cylinder engines (unfortunately, I don't have the specific engine code). Of the TSI engines, I have at least seen a chain replacement in 3 out of 4. The maximum distance was almost 3.5tkm in extremely short-distance operation. Specifically, if the vehicle is not level, but tilted, it can very quickly become unstable.

Thank you

...of the chain or to skip links. That's why there are also modified chain cases or chain tensioners that should prevent this.

...Sorry for the missing part...

Okay, thanks.

As far as I know, the improved chassis and other components have already been in series production for quite some time, and we can hopefully drive one of the mature CAX models . . .?

....have you been able to hear this rattling/thudding noise again (only on cold start) ??? Regarding maturity... either hope or CAXA dies last...

PS: How is the terrain?

The Rapid is usually driven by my better half alone. I ask them all a few days apart if they have heard it again - so far, no.

Approximately 2 x 20km daily, plus occasional additional trips (shopping, etc.). Long-distance only very rarely.

...would still like to be there in the morning at the start and check if anything is rattling. Women are sometimes a bit "deaf" in that regard...

The noise seemed to be back yesterday, this time I heard it from the outside.
Actually, there's no rattling, but rather more of a slow "wupp" sound, as if the engine is swaying in its bearing

I will try to anticipate the next occurrence (it seems to occur more frequently after about 3 hours of inactivity) and then have the hood open when the engine is started.

...also, wenn der Motor "wuppt", passt das Gerät normalerweise nicht zu einer geraden Steuerkette. Denn es klingt eher nach einem mehreren Hydrostösselklappen...heller Klang und relativ hohe Frequenz. "Wuppen" sounds more phonetically like a lower frequency...
