2020-2024 Porsche Taycan Dashboard End Cap: A Fix for Common Rattles
Your guide to diagnosing a loose or rattling dash end cap, what to inspect on a used part, and how to perform the simple replacement.
- The most common failure is a rattle or buzz, which is very noticeable in the Taycan's quiet cabin. A TSB exists for dashboard noises, confirming it's a known issue.
- When buying a used end cap, the condition of the rear mounting clips is more important than minor cosmetic scuffs. Broken clips will guarantee a poor fit and more rattles.
- A new OEM end cap is extremely expensive (often over $1,000), while a used OEM part can be found for under $80, offering massive savings.
- Replacement is a very easy DIY job that takes less than 10 minutes and only requires a plastic pry tool.
Symptoms of a Failing Dashboard End Cap
Since the dashboard end cap is a simple trim piece, it doesn't have mechanical or electrical failures. Instead, problems are related to its fit, finish, and the noise it makes. Because the Taycan cabin is so quiet, even minor trim rattles can be very noticeable and annoying.
- Rattling or Buzzing Noises: This is the most common complaint. A buzzing or rattling sound may come from the far left or far right side of the dashboard, especially when driving over less-than-smooth roads. The noise often stops if a passenger presses firmly on the dashboard end cap or the surrounding area.
- Poor Fitment: The end cap may not sit flush with the rest of the dashboard or the A-pillar trim. You might see an uneven gap, or one edge might stick out. This is often a sign of broken mounting clips.
- Visible Damage: The part may have obvious cosmetic damage like deep scratches, scuffs, or cracks from being hit by a seatbelt buckle or during previous service work.
Known Issues, TSBs, and Recalls
While there are no safety recalls for the dashboard end cap, Porsche has acknowledged issues with interior noises in the Taycan.
- TSB for Dashboard Noise: Porsche issued Technical Service Bulletin (TSB) #2201 for "mechanical noises from the drivers side dashboard" on the 2020 Taycan. This indicates that rattling in this area is a recognized issue. Forum discussions among owners confirm that rattles from various dashboard trim pieces are a common frustration.
- No Recalls: The dashboard end cap is not a safety-critical part and has not been subject to any recalls. Major recalls for the 2020-2024 Taycan primarily concern the high-voltage battery system and do not involve interior trim.
Pro Tip: Some owners have reported that dashboard rattles began after the vehicle had major service performed, such as a heater repair that required dashboard removal. If you are buying a used Taycan, ask the seller about its service history, as a misaligned dashboard from a previous repair could be a source of future rattles.
Buying a Used 2020-2024 Taycan Dashboard End Cap
Given the extremely high cost of a new OEM end cap, a used part is the most logical choice for a replacement. The key is to inspect the part carefully, paying more attention to the back than the front.
What to Inspect:
- Check All Mounting Clips: This is the most critical step. Turn the part over and inspect every single mounting tab and clip receiver. They are essential for a tight, rattle-free fit. If any of these plastic tabs are cracked, stressed, or broken, the part will not install securely and will almost certainly rattle. Do not buy a part with damaged clips.
- Inspect the Cosmetic Face: Check the visible surface for deep scratches, discoloration, or damage to the texture. Minor scuffs may be acceptable, but deep gouges will be noticeable. For Taycans with optional leather dashboards, ensure the leather on the used part is not peeling, cracked, or stained.
- Verify the Color and Finish: The Taycan was offered with numerous interior color schemes like Black, Bordeaux Red, Chalk Beige, and Slate Grey. Ensure the color of the used part matches your vehicle's interior. Part numbers often vary by color, so matching the part number is the best way to guarantee a match.

Replacement Guide (Difficulty: 1/5)
Replacing the dashboard end cap is a very simple task that most owners can do themselves in a few minutes. The only tool required is a plastic trim removal tool (also called a pry tool) to prevent scratching the dashboard.
Estimated Time: 10 minutes
Tools Needed: Plastic trim removal tool
- Open the front door fully to get access to the end of the dashboard.
- Carefully insert a plastic trim removal tool into the seam between the end cap and the main dashboard.
- Gently pry outwards. The panel is held in by several pressure clips. You will hear them pop as they release. Work your way around the panel until it comes free.
- Before installing the new part, look inside the dashboard opening to ensure none of the old clips broke off and remained in their slots.
- Align the clips on the new end cap with the corresponding slots in the dashboard.
- Press firmly and evenly around the panel until you hear and feel all the clips snap securely into place.
- Check that the panel is flush and does not move when you press on it.
Warning: Do not use a metal screwdriver or other hard tool to pry the panel off. The soft-touch dashboard and adjacent A-pillar trim can be easily scratched or dented.

Frequently Asked Questions (FAQ)
Is the left (driver side) end cap the same as the right (passenger side)?
No, they are mirror images of each other and have different part numbers. The right side is part number 9J1857176, and the left side is 9J1857175.
Do I need any special tools for replacement?
A plastic trim removal tool is highly recommended. Using one will prevent you from scratching or damaging the soft dashboard material or surrounding trim. They are inexpensive and available at any auto parts store.
Will a broken dashboard end cap cause any warning lights?
No. This is a purely cosmetic trim piece. It has no electronic components and will not trigger any dashboard warnings or fault codes.
Why is a new OEM end cap so expensive?
The high cost is typical for genuine Porsche interior parts. Prices can be even higher for versions with optional stitched leather, which can cost over $2,000 for a set. This makes finding a quality used OEM part a significantly better value.
