Is your 958 headlight suffering from...

These are the most common signs of water ingress in the Porsche Cayenne 958 headlight.

💧 Condensation inside the lens
🌊 Water pooling in the headlight
⚠️ Error messages in the car
💡 Flickering or dim lights
🔄 Low/High beam failure
🚫 Headlights completely non-functional
🔍 MOT failure due to headlights not functional or impacted beam pattern

Water ingress is a widespread problem on 958 xenon, adaptive xenon, LED, and adaptive LED headlights. It's typically caused by factory headlight sealant failure, seal degradation, or blown gaskets - and once water gets in, it doesn't get better on its own.

What's included in the service

Every refurbishment follows our full 15 point process which has been refined over thousands of headlights, regardless of headlight variant. Have a look at an overview of our process.

01 Full Inspection

Thorough check of connectors, internal wiring harness, casing, lens, and internal cosmetic shrouds & surrounds for corrosion and damage.

02 Complete Strip-Down

Full disassembly of the headlight down to the barebones with all wiring, projectors, reflectors, and all other internal components removed for assessment.

03 Decontamination & Clean

Chemical cleaning and decontamination of all internal surfaces, projectors, reflectors, and components.

04 Component Testing

Every internal electrical component is checked and tested via bench testing for damage caused by water exposure - both short or long term.

05 New Lens & Reseal

Brand new lens fitted and headlight sealed with professional OEM grade adhesive, then fully bench, functional, and water tested.

06 Final QC & Reassembly

Full quality inspection, reassembly of external components, and functional verification sent to you before the headlight leaves us

From light misting to completely non-functional - we repair any severity of water damage, with new lenses, gaskets, and seals included as standard.

⚠️ Important - Please Read

Understand what this service covers and its limitations before ordering.

New lenses, upgraded gaskets, new seals, & internal chemical clean all included as standard
Rebuilt to meet and exceed factory spec - we use specialist sealants and in house gaskets
New internal and external wiring harnesses available for selected variants if required
Does not cover external electrical items such as LED drivers or control units
Will not resolve pre-existing module or electrical components issues within the headlight
⚠️ Water exposure may have caused component damage beyond this service's scope
‼️
Control units or electrical components that have been exposed to water (no matter the amount or duration) are at risk of becoming damaged and/or corroded. We MUST be made aware of this if it has happened. Control units may fail as the internal PCBs are not water resistant. We take no liability or responsibility for any control units or electrical components which cease functioning at any time pre, during or post service due to contact to water.

How it works

Everything is booked in advance so we can guarantee turnaround times and availability. Get in touch first - don't just send headlights without a booking.

01 Get in Touch

Contact us to confirm your headlight variant and discuss your requirements. If your headlights have been previously repaired or tampered with by anyone else, let us know as this will affect pricing and turnaround time.

02 We Book You In

We check our calendar and schedule you in for fitting or postal refurbishment - whichever suits your situation. A non-refundable 25% deposit secures your booking.

03 Assessment & Confirmation

We assess your headlights, confirm the scope of work, and flag any additional costs such as control units. We'll get your authorisation before proceeding.

04 We Refurbish

Your headlights go through our full refurbishment process. Once complete, we contact you with photos showing everything is fully functional.

05 Balance Due & Collection

Remaining balance is due once the work is complete. Collect your headlights or car from us, or we ship via DHL Express to mainland UK (including Northern Ireland).

⚠️ Previous Repairs

If anyone else has previously attempted a repair on your headlights, you must let us know in advance. This will affect the scope and pricing of the service.

Turnaround times are based on pre-booked appointments that have been booked in advance where the headlight condition matches what was discussed, the headlight is completely dry inside and the headlight is complete. If additional work is required upon assessment, turnaround times may be extended. Headlights must be completely dry internally for this turnaround time, if the headlight needs drying out then this time will be added to the refurbishment turnaround time.

Full Symptom List


Depending on what your headlight variant is, you may have some or all of the failed functions and/or errors on the instrument cluster.

Functional failures & symptoms

  • Water ingress
  • Heavy condensation & excessive misting on the inside of the headlight
  • Sidelights not working
  • Low beam not working
  • High beam not working
  • Adaptive not working
  • Vertical aim not working

The Solution


As part of our refurbishment and repair service, we'll carry out the following:

  • Inspect the headlight to ensure that there's no corrosion on the headlight plugs/sockets
  • Pressure test the headlight to identify the source of the water ingress
  • Remove the headlight lens non-destructively and remove all of the old sealant
  • Dry the headlight out to remove all traces of water
  • Apply specific fluids and greases to remove light corrosion internally
  • Supply and fit a new aftermarket headlight lens
  • Replace all factory liquid gaskets with KYCS uprated gaskets that exceed OEM specification
  • Apply specific fluids and greases to the factory cap seals to replenish and revitalise them
  • Pressure test & water test the headlight to ensure that there isn't any water ingress in the future

If you have intermittent error codes on your instrument cluster or the following exterior lights aren't constantly working (DRL, sidelights, low beam, high beams), this typically points to a faulty water-damaged control module. We can fit a control unit that's supplied to us at the same time for no additional cost. This service does not include any exterior components such as the control units or electrical components. Our repair process is to the bare headlight as outlined above. If your headlight is water damaged, multiple components are likely water damaged/corroded and might need replacing - our repair service does not include replacement electric components.

Replacement components used in the refurbishment service are aftermarket unless specified.

Affected Vehicles/Headlights


  • Porsche Cayenne 958.1
  • Porsche Cayenne 958.2

Fitting


If you want us to remove and refit the headlight during the repair service, please get in touch to get our availability. Our fitting days are Tuesday, Wednesday, Thursday, and Saturday. We have AM and PM slots available.
