🔧 Q5 - Headlight Bulb Replacement

On your Q5 Prestige, headlight “bulbs” may not be replaceable like older halogen systems. Many Prestige headlights are LED (sealed or module-based), while some setups use HID (xenon) for low beam—each has a different repair path.

Difficulty Level: Intermediate | Estimated Time: 0.5-2.5 hours

⚠️ Safety & Precautions

• ⚠️ Turn ignition off and remove the key before working near headlights.
• ⚠️ Let the headlight housing cool; it can get hot.
• ⚠️ If your Q5 has HID/xenon, the igniter produces very high voltage—do not power the lights with parts unplugged.
• ⚠️ Avoid touching any glass bulb with bare fingers (skin oils shorten bulb life).
• ⚠️ Battery disconnect is recommended if working on HID/LED modules.

📋 Before You Begin

• Park on level ground, set the parking brake, and turn the headlights off.

• If your Q5 has HID/LED modules (common on Prestige), disconnect the battery negative terminal using a 10mm socket (negative is the “-” terminal).

🔨 Step-by-Step Instructions

Before I give the exact steps, I need 2 quick details so I don’t steer you wrong:

• Which light are you replacing: low beam, high beam, or both?
• What headlight type do you have: LED or Xenon/HID? (You can tell by the headlight label under the hood, or send a photo of the headlight lens and the back of the housing.)

Tip: Many Prestige LED headlights do not use “bulbs.”

If you reply with those 2 answers (or upload a photo), I’ll give you the correct, exact step-by-step for your Q5—including whether it’s an access-cover bulb swap or a headlamp/module removal job.

✅ After Repair
