Review: WORKS PERFECTLY FINE FOR MY SKODA OCTAVIA VRS 2014 - Works perfectly fine, no issues at all.
Review: Rubbish - Absolute rubbish, I’ve only given 1 star as it wouldn’t let me give zero! Had to remove wheel, wheel arch liner, front bumper and headlamp to replace the ballast module, plugged the light in and it worked. Rebuilt and tried the lights, headlamp didn’t work. Very annoyed I thought it can’t the ballast as it’s brand new so ordered new xenon bulbs, stripped out whole front end again and changed bulb, still didn’t work, had to rebuild as car was needed to get to work. Purchased another ballast from a different supplier, stripped it all out again, fitted another ballast and worked straight away. I’ve wasted hours of my time and spent out on other items only to realise this product is trash! Steer clear and buy from elsewhere!

### ⭐⭐⭐⭐⭐ Fixes headlight issues
*by M***S on 10 December 2022*

Fitted these to my A4 headlight after it was intermittently going on and off and showing the bulb error warning on the dashboard. Moisture had got in and damaged the old ballast, so addressed the Moisture problem by drying out and putting extra seals around joints, fitted this and works great. P.s. it was exactly the same part as the original OEM VW/Audi part that came off.
