Audi Q7 fog light: replace a cracked or fogged-up unit without going to the dealership
This front fog light matches the exact cutout of the Audi Q7 bumper from 2010 to 2015 and corresponds to manufacturer part numbers 4L0941699 for the left side and 4L0941700 for the right side. On this generation of Q7, these lower units are the first to suffer: lens chipped by gravel, tarnished reflector, condensation after rain. Replacing it with a complete unit solves the problem in one go.
Why replace the entire fog light unit
- Complete unit: lens, reflector, and housing are new, not just the bulb.
- Two bulbs included: one halogen bulb and one LED bulb are supplied with the unit, with the base depending on the model.
- Original part numbers: matches 4L0941699 and 4L0941700 for a fit without modification.
- Sold individually or as a pair: you only pay for the side you need.
- Original connection: connects to the vehicle's existing connector.
Q7 front fog light: left, right, or the pair
A fog light shines low and wide, just below the fog line, where low beams only reflect a white wall. On the Audi Q7 4L, the two units are not symmetrical: part number 4L0941699 fits the driver's side and 4L0941700 the passenger side. Three options are available: the left and right pair when both lenses are worn out, or a single side when a parking collision has only affected one unit. Check the part number on your removed lens before ordering.

Installation and maintenance
Access to the unit is through the lower grille of the front bumper: unclip the trim, remove the mounting screws, disconnect the connector, then insert the new lens into its housing. Allow 20 to 30 minutes per side with a screwdriver and socket. Before closing everything up, turn on the fog light and check the beam height on a wall: a light that is too high will dazzle and lose all usefulness. A regular rinse of the lens is then enough to maintain performance.
Frequently asked questions
Which part number corresponds to the left side?
Part number 4L0941699 designates the left unit, driver's side. The right side has part number 4L0941700.
Do I need to buy both sides?
No, each side is available separately. The pair is recommended if both lenses are the same age, to maintain an identical appearance.
Does installation require removing the bumper?
No, access is through the lower grille of the bumper after unclipping the trim.
Which bulb should I use, the LED or the halogen?
Both are included. The LED gives a whiter, more modern light, while the halogen provides a warmer look closer to the original.
Why was my old fog light full of condensation?
The housing seal eventually hardens and lets moisture in. This is irreparable on a sealed unit: only a complete replacement solves the problem.
Give your Q7 a clean front end again: a new unit, twenty minutes of installation, and low beams become truly useful again.
