📋 Procedure
ℹ️ Torque figures below come verbatim from workshop data — always cross-check against your vehicle's factory manual before final tightening.
Notes:
Different versions of burner element and glow plug with flame monitor -Q8 (attachment with bolt or clip)
Between start of production and 06.99, glow plug with flame monitor -Q8 was attached in burner element with bolt -A- (gradual conversion).
Between 06.99 and 11.01 (gradual conversion), glow plug with flame monitor -Q8 was attached in burner element with clip -C-.
As of 11.01 (gradual conversion), glow plug with flame monitor -Q8 has been attached in burner element with clip -B-.
The design of clip -B- is such that the dissipation of heat at glow plug -Q8 is better than with clip -C-. Exclusive use is therefore to be made of burner elements where the glow plug is attached with a bolt or clip -B-.
As of 02.03 modified auxiliary heaters are gradually being introduced into production featuring burner element -C-, clip -B- and glow plug -A-. These components are matched and must always be installed together (do not combine different versions).

.
Remove bolts -A- (or clip).
Pull glow plug with flame monitor -B- out of burner element.
Notes on installation:
Bolt -A- is only to be tightened to approx. 0.5 Nm; greater torque could damage glow plug.
Check burner element and replace element as well in the event of a defective glow plug if deposits have formed in burner element which would affect operation and cannot be removed using workshop equipment.
Fix wiring in position in clip -D- and route as shown.
Check proper positioning of grommets -C- after installation.
Check non-insulated part of wire to glow plug before installing combustion air blower; wires must not make mutual contact or come into contact with other components (danger of short circuit).
In the case of burner elements where glow plug -Q8 is attached with clip -B-, pay attention to firm fit of clip and make exclusive use of burner elements where glow plug is attached with a bolt or clip -B-.
As regards version gradually being introduced as of 02.03, pay attention to correct installation position (Fig.) and firm attachment of clip -B-.

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.
