- ⚠ Always wear eye protection and gloves when removing and installing gas discharge lamp!Eye protection and gloves are necessary because the glass bulb of the gas discharge lamp is mechanically very sensitive and the interior of the bulb is under a pressure of 7 bar (cold) to 100 bar (warm) and the temperature around the lamp bulb can reach up to 700 degrees Celsius. — Carefully pull out gas discharge lamp. [Note: Do not touch bulb glass when fitting a gas discharge lamp. Fingers leave traces of grease on the glass, which evaporate when the gas discharge lamp is switched on and cause the glass to cloud over.Take great care when handling the gas discharge lamp (ensure the bulb is not stressed mechanically). The bulb glass is extremely fragile and has a high internal pressure.]

Who makes these pages, and how
TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.
The figures on this page come from manufacturer workshop documentation and are shown as they are. The page is assembled automatically from that data — it is not written by an AI. The AI works in the chat, where it answers for your specific car. It writes nothing here.
Variants of the same model differ. Cross-check torque against the factory manual for your engine before final tightening.
