BMW F20 F21 Headlight Refurbishment & Repair From Water Damage
We'll completely overhaul and rebuild your headlights with our 15-point process, which includes new lenses, upgraded headlight gaskets, new seals, a chemical clean, and more. This will leave you with refreshed headlights that exceed factory specifications and stop the common water ingress issue for good.
Please read this page to understand this service and its limitations. If you have pre-existing module issues within your headlight, this service will not resolve them. This service does not include fixing, repairing, or replacing any external electrical items such as LED drivers or control units. It's accepted that if you have water ingress in the headlight, there is a strong chance that components will have been exposed to water and caused some sort of damage, whether it's short or long term.
Service Information
Symptoms
Is your F20 F21 (pre facelift/LCI) headlight suffering from one or more of the following?
- Water ingress
- Heavy condensation & excessive misting on the inside of the headlight
- Angel eyes are not working
- Eyebrow not working
- Headlight lighting system failure/headlight adaptive failure/vertical aim failure on your speedo & iDrive system
If that's the case, we've got you covered - our refurb and repair service will get your headlight back to how it should be without buying new ones.
The Cause
Water ingress is a widespread problem on the F20 F21 xenon/adaptive xenon headlights. It's usually from the factory headlight sealant failure, seals' degradation, or blown gaskets.
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/vertical aim error or the following exterior lights aren't constantly working (angel eyes, eyebrow), 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 can rebuild the existing harness for additional cost.
If a rebuilt 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.
Replacement components used in the refurbishment service are aftermarket unless specified.
