Suddenly +while driving down to the city of Porlezza itself, a "ticktack" sound +appeared, while driving in the corners. + +First it came to my mind that maybe a stick or a leave or something +similar was caught in the wheels and I did not pay too much attention +to it. + +The following days the sound would not vanish and about 2 years later, +this is still the case. + +## The sound + +First of all, this is not the noise caused by [the Ackermann +effect](https://en.wikipedia.org/wiki/Ackermann_steering_geometry)). +Porsches have the strange behaviour that when the whell is fully +turned and the tyres and not warm, there is a sound from rubbing. + +That's not what I am talking about. Instead it as a coming and going +"click" sound, as if something is hit by something turning. Imagine a +plastic slightly bended, that you push to its extreme and the with +force it gets back into its original position and hits something. + +That is roughly the sound I am talking about. + +It is temperature, wheel, speed and angle dependent. + +## Temperature dependency + +Initially the sound would only manifest if it was warm weather. So I +suspected something might be influenced to be more loose or might have +grown due to temperature effects. + +While in the beginning it was only audible at higher temperatures +(above 25C), over the two years that the sound came and went, it also +appeared at all temperatures between 0C and 35C. + +## Wheel dependency + +Initially only the bigger summer wheels would cause this noise. Later +in 2024, the winter tyres (different rimms, different tyres) would +also start to make the same sound. + +## Speed and angle dependency + +Now this is a simple one. The faster you go, the stronger the angle +is, the louder the sound is. If I drive straight on a parking lot, +there is no sound. If I drive left or right on parking lot, the sounds +is there. + +If I exit a highway (long fast corner), the sounds is very loud. + +## Repair tries + +Since 2023-08-20 the [Porsche Center +OZS](https://dealer.porsche.com/ch/obererzuerichsee/de-CH) +has been repairing this and took various approaches: + +* Change wheels - to ensure it's not a problem in the wheels. + Initially and strangely this helped when switching from summer to + winter tyres. Later to be happening on any wheel. +* Disassemble the summer wheels - the wheels have covers, which can + accumulate dirt and according to the Porsche center it is possible + that dirty causes that sound +* Disassemble the brakes - as well as the wheels, the brakes can also + collect dirt and again, same story, are potentially making the + sound. So in June 2025 the brakes were cleaned. + +## Full History + +This is a very particular issue, because the failure started on +**2023-08-20** and has not been fixed as of **2025-05-24**. + +In 2023 when the problem first appeared, the car was on summer +tyres. After several tests the Porsche center concluded that the +problem must be dirt below the cover of the wheels, because +the wheels of the Taycan have covers to make it more +aerodynamic. Great stuff in theory. + +The Porsche center disassembled the front wheels, cleaned them, put them +back together and send me a bill of about 2000 CHF. A few days later, +the sound reappeared. + +Unfortunately I had to change to winter tyres soon after, which are +are smaller wheels (20" instead of 21"). During the winter the sound +was gone, so the Porsche repair center reasoned it must have been the +summer wheels. My assumption was that something of the wheels is +actually touching other car parts. My assumption has not been rebutted +yet, however the one of the Porsche repair center has been: + +After several repair tries in 2024, a replacement of the front wheels, +the winter season of 2024 started. And interestlingly, the sound did +reappear with the winter tyres now as well. + +After switching to summer tyres in 2025, the sound was gone for a few +days, just to reappear. As of writing this article on 2025-05-24, the +car is again back in the repair center. + +A bit more background to the sound: it sounds like a ticktack with +something stopping (like a plastic), being bended and then popping out +to make a sound. Almost like an unpleasant instrument. When you drive +down the mountains of Switzerland and you drive through 180 degree +corners, it as very loud, even louder than regular radio music. + +It is also audible at low speed when the steering wheel is fully +turned or when one leaves the highway and the highway exit is a +corner. So essentially one car hear it at a speed of somewhere around +5 km/h up to somewhere around 100 km/h. + +Someone suggested this might be a (known) problem of Porsche ceramic +brakes, but this theory was rebutted by the Porsche repair center. + +As of today, the Porsche repair center did actually clean the brakes +and says it has been fixed. + +## Current state + +After the brake cleaning in June 2025, I did not have the possiblity +to drive the car again, I will report back back here in July 2025. + +## Review + +So many things wrong and so much effort. It is for me hard to believe +how difficult it seems to fix such a simple problem. + + +[[!tag porsche car]] diff --git a/blog/nicos-porsche-taycan-experience.mdwn b/blog/nicos-porsche-taycan-experience.mdwn index 022b33ce..ada7319b 100644 --- a/blog/nicos-porsche-taycan-experience.mdwn +++ b/blog/nicos-porsche-taycan-experience.mdwn @@ -40,6 +40,9 @@ How [does it actually drive, if it drives?](/blog/nicos-porsche-taycan-experience-part-3-driving) Unfortunately, the driving cannot be enjoyed so much, if there are [quite some rattling and squeaking noises](/blog/nicos-porsche-taycan-experience-part-4-rattling-squeaking). +While those have mostly been fixed, there is unfortunately more to +fail and generate noise: there is for instance +the [so far unsolved ticktack sound when turning the wheels] More to come soon... @@ -51,7 +54,9 @@ For easier access: * [Part 2 - The suspension failure](/blog/nicos-porsche-taycan-experience-part-2-suspension-failure) * [Part 3 - driving](/blog/nicos-porsche-taycan-experience-part-3-driving) -* [Part 4 - rattling and squeaking](/blog/nicos-porsche-taycan-experience-part-4-rattling-squeaking) +* [Part 4 - rattling and + squeaking](/blog/nicos-porsche-taycan-experience-part-4-rattling-squeaking) +* [Part 5 - ticktack wheels](/blog/nicos-porsche-taycan-experience-part-5-ticktack-wheels) * [The key battery replacement](/blog/nicos-porsche-taycan-experience-key-battery-replacement)
