Fog Lamp Bulbs and Exhaust System

The left fog lamp went out. After dismantling the “non-serviceable” housing, it was found that moisture had entered the control unit through the power cable. The driver was repaired, and the lamps worked for another month.

Soon, the left lamp failed again, this time taking a 10A fuse (driver’s side No. 26) with it. Moisture was again the culprit, causing almost everything inside the block to burn out.

The same type of lamps was ordered.

During installation, the wire entry point into the control unit was sealed with silicone, suspecting that liquid entered from the headlight washer hose.

Preventative measures:

Anti-corrosion update on beams and welds / Dinitrol 4941
Headlight washer hoses, sealing rubbers, and wires were coated with silicone / LiquiMoly 3312
All bolts were lubricated with WD-40

Although a lux meter wasn’t available, subjectively, the lamps are bright. The fog lamps were adjusted at the service station, not causing glare. The color is white, without any hint of blue or yellowness.
