Choosing the Right Fit for Your Porsche

Where Lucas is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side or position, and connector type where relevant.

• Typical reasons to choose Lucas parts include resolving intermittent electrical faults, restoring reliable starting, charging and lighting, and keeping older Porsche models dependable.
• Common electrical symptoms include intermittent electrics, weak charging, flickering lights, misfires and faults that change with moisture, vibration or temperature, often made worse by poor grounds or corroded connectors.
• As a practical check, many technicians will inspect and, if necessary, renew tired relays and fuses, especially if they show signs of heat damage.
• Cleaning and protecting electrical connectors is often worthwhile, as poor connections account for many so‑called “mystery” faults.
• It is good practice to check battery health and main earth points first, because low system voltage can create false errors across multiple vehicle systems.

If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the wording grounded.

Engine Electrical — Engine electrical components are replaced when there are starting, charging, ignition or sensor-related faults that affect how your Porsche runs day to day. Typical issues include intermittent no-start, rough running, misfires, poor charging, warning lights and heat-related failures.

• Before replacing components, it is sensible to confirm faults with basic tests such as battery load testing, checking power and grounds, and inspecting connector condition.
• Electrical diagnosis is more reliable when you use live data and simple voltage-drop checks rather than relying only on stored fault codes.

Starter Motors — Starter-related parts are selected when the engine cranks slowly, intermittently or not at all, even with a healthy battery. Real-world reasons for replacement include worn internal components, heat-soak issues near exhausts, or high resistance in the starter feed and earth paths.

• If you experience a single click with no crank, or slow cranking, it is worth measuring voltage at the starter during cranking and checking main power and earth cables.
• Load testing the battery and checking voltage drop on the main earth strap can help you distinguish between a weak battery and a failing starter.

Lighting — Lighting components are chosen to maintain visibility, safety and compliance. Owners often replace or upgrade lighting to improve night-time vision, refresh tired or yellowed lenses, address condensation issues or meet local regulations.

• If lamps mist up, checking housing seals and vents and clearing blocked drains can reduce water ingress; pooled water inside the unit usually indicates failure.
• When upgrading to LED bulbs, use suitable CAN-compatible parts where required and ensure they remain road legal and correctly aligned.

Indicators Front — Front indicators are renewed when lenses crack, units leak, bulb holders corrode or when refreshing faded amber lenses. Clear, bright indicators are critical for visibility, avoiding test failures and maintaining the car’s appearance.

• Fast-flashing indicators usually point to a failed bulb or an LED conversion that lacks the correct load or CAN support.
• Cleaning contacts and renewing seals can help prevent hyperflash and water-related faults in front indicator units.

Light Bulbs — Bulbs are routine service items and are replaced for reliability, visibility and legal compliance. Many Porsche owners also upgrade to higher-output or more modern bulb technology, where suitable, to improve night driving and overall clarity.

• Replacing bulbs in pairs helps keep colour and brightness consistent from side to side.
• Frequent bulb failures can indicate issues such as over-voltage, poor earths, vibration or moisture in the lamp housing.
