Electrical issues in the E-Class can stem from a few key factors:

Battery and Alternator Health: A weak battery o r failing alternator often causes flickering lights and electronic glitches.

Wiring and Connectors: Exposure to heat, moisture, o r poor road conditions in Pakistan can corrode o r loosen electrical connectors.

Aftermarket Accessories: Non-genuine o r improperly installed accessories can interfere with the car’s electrical system.

ECU Electronic Control Unit Problems: Sometimes the car’s computer may need a software update o r repair.

Solution: Regularly check battery health, use genuine parts, avoid water exposure, and have authorized service centers perform diagnostics to fix ECU o r wiring issues.
