Check the transmission shift quality | Description: While driving, pay attention to the 7G-DCT gearbox. Hesitation or jerky shifts at low speeds in cars of this age can be a sign that the mechatronics unit or the clutch packs are approaching the end of their service life.
Listen closely to the cold start | Description: Start the car from completely cold. Listen for a momentary rattle from the engine bay, which can sometimes indicate the timing chain tensioner may require professional inspection to ensure optimal engine longevity.
Test the infotainment and electronics | Description: Check this by cycling through all menus on the screen. Flickering displays or unresponsive rotary controllers are worth noting, as electrical gremlins can occasionally crop up in these units as they mature.
Inspect the sunroof and window seals | Description: During your check, look for any signs of dampness in the footwells or headliner. It's common to consider clearing the sunroof drains periodically to prevent water ingress, which can be an annoyance if left unaddressed.
Consider a major service including spark plugs and transmission fluid flush.
