BMW 5 Series F10 F11 F07 Headlight Refurbishment & Repair From Water Damage
Is your F10, F11 or F07 headlight suffering from...
These are the most common signs of water ingress in the BMW 5 Series headlight.
Water ingress is a widespread problem on F10, F11, and F07 halogen, xenon, adaptive xenon, 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 5 Series headlights, regardless of headlight variant. Have a look at an overview of our process.
Thorough check of connectors, internal wiring harness, casing, lens, and internal cosmetic shrouds & surrounds for corrosion and damage.
Full disassembly of the headlight down to the barebones with all wiring, projectors, reflectors, and all other internal components removed for assessment.
Chemical cleaning and decontamination of all internal surfaces, projectors, reflectors, and components.
Every internal electrical component is checked and tested via bench testing for damage caused by water exposure - both short or long term.
Brand new lens fitted and headlight sealed with professional OEM grade adhesive, then fully bench, functional, and water tested.
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.

Delivery & fitting options
Mainland UK only, excluding Highlands, Islands, and Remote areas. You can mix service levels per side - for example, standard on one headlight and full refurbishment on the other.
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.
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.
We check our calendar and schedule you in for exchange, fitting, or postal refurbishment - whichever suits your situation. A non-refundable 25% deposit secures your booking.
We assess your headlights, confirm the refurbishment type (standard or full), and flag any additional costs such as control units. We'll get your authorisation before proceeding.
Your headlights go through our full refurbishment process. Once complete, we contact you with photos showing everything is fully functional.
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).
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
~2 hrs

Exchange at KYCS Oldbury

Sending/dropping off to KYCS Oldbury
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. Adaptive LCI xenon and adaptive LCI LED headlights are not available on exchange - these follow the 3-day turnaround as we refurbish your own headlights, and we prefer to have the car on-site due to the complexity of the headlights involved. 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.
Shipping with DHL Express
Anything larger than 50x45x40cm will need a custom quote from DHL. We'll confirm all shipping details with you after booking.
Core Exchange Programme
Same-day turnaround when fitting at our Oldbury location. We use our in-stock headlights to build yours to spec, then take your current pair in on exchange - minimum downtime for you.
Inventory headlights
Exchange criteria
Headlight(s) you provide in exchange must meet all of the following:
If your headlights don't meet the exchange criteria
Don't worry - we'll always do our best to help and find a solution. If your headlights don't qualify for exchange, we can look at purchasing from our stock inventory at list price (subject to availability), or in worst case scenarios we can source headlights on your behalf and bill accordingly. If neither option is available, you'll need to either leave the vehicle with us for the quoted turnaround time, or we'll refit your original headlights. Fitting rates and non-refundable deposits are retained in all cases.
Payment & how to order
All bookings are secured with a 25% non-refundable deposit, automatically applied at checkout. The remaining balance is invoiced once the work is complete.
Industry-leading coverage on F10 F11 F07 refurbishment & repair

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 iDrive and instrument cluster.
Functional failures & symptoms
- Water ingress
- Heavy condensation & excessive misting on the inside of the headlight
- Angel eyes not working
- Eyebrow not working
- Indicator not working
- Orange 3 LED corner marker not working
- Adaptive not working
- Vertical aim not working
iDrive & instrument cluster errors/warnings
- Side/daytime lights fault on the iDrive and instrument cluster
- Daytime/parking lamp malfunction on the iDrive and instrument cluster
- Turn indicator front failure on the iDrive and instrument cluster
- Adaptive headlights failure on the iDrive and instrument cluster
- Headlight vertical aim control failure on the iDrive and instrument cluster
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 iDrive for lighting system failure/adaptive system failure or the following exterior lights aren't constantly working (angel eyes, eyebrow, 3 orange corner dots, indicators), this typically points to a faulty water-damaged TMS module. We can additionally fit a new TMS that's supplied to us at the same time for no additional cost. We only supply brand-new genuine TMS modules from the main dealer and don't recommend using aftermarket suppliers or products. This service does not include any exterior components such as the TMS or angel eye drivers. 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. However, we do hold them in stock.
If your TMS socket is corroded or water-damaged, we now have brand new aftermarket replacement internal harnesses covering the external headlight plug and TMS socket for the following headlights:
- F10 F11 F07 pre LCI xenon
- F10 F11 F07 pre LCI adaptive xenon
- F10 F11 F07 xenon
- F10 F11 F07 adaptive xenon
If a new harness is required due to the constant water ingress for an extended period of time without any resolution steps being taken, we will notify you when the TMS socket is inspected. Depending on your headlight variant, harnesses will either be brand new aftermarket, or your OEM harness rebuilt using aftermarket components.
Replacement components used in the refurbishment service are aftermarket unless specified.
Commonly Water Damaged (External) Components
On the pre-LCI xenon/adaptive xenon headlights, the following items are usually water damaged and may need replacing based on our previous experience:
- TMS module (high likelihood)
- Angel eye drivers (low likelihood)
- LED indicator units (very low likelihood)
On the LCI xenon/adaptive xenon headlights, the following items are usually water damaged and may need replacing based on our previous experience:
- TMS module (high likelihood)
- Angel eye drivers (high likelihood)
This is a generalisation, and components may or may not apply in your situation - if you'd like to have a chat to have a better understanding of what would more than likely be applicable in your case, please get in touch and we'll schedule a call with you.
