Product Information

Full details

This Bosch glow plug (0250603026) is designed for diesel engines requiring reliable starting performance, especially in colder conditions. Its key benefit is the after-glow capability, which aids in post-start combustion. A potential caveat is the specific voltage and thread size requirement, necessitating careful application checks. This pencil-type glow plug features a 7V rating, M 8 x 1.0 thread, 120 mm length, and a PIN port connector.

FAQs

What is an 'after-glow' capability?

After-glow means the glow plug continues to heat up for a period after the engine has started, helping to maintain combustion temperature and smooth running, especially in cold conditions.

How do I know if I need to replace my glow plugs?

Common signs include difficulty starting in cold weather, rough idling, increased exhaust smoke, or a glow plug warning light on the dashboard.

What does 'Duraterm' mean?

Duraterm refers to a specific type of glow plug technology known for its durability and efficient heat retention.

Can I use a 12V glow plug if my vehicle requires 7V?

No, using a glow plug with an incorrect voltage rating can damage the glow plug, the engine control unit, and potentially cause starting issues.

What is the correct tightening torque for this glow plug?

The specified tightening torque range is 6 Nm to 10 Nm. It is crucial to use a torque wrench for accurate application.

Is this glow plug compatible with my non-VAG vehicle?

This specific glow plug is designed for VAG vehicles (Audi, Seat, Skoda, VW) and their associated OEM part numbers. Compatibility with other brands should be verified using cross-reference numbers or by consulting a parts specialist.

Troubleshooting

Engine fails to start in cold weather

Check glow plug electrical connections for corrosion or looseness. Verify the glow plug relay and fuse are functional. Test individual glow plugs for continuity.

Rough idling or engine misfires

A faulty glow plug can cause incomplete combustion. Test each glow plug's resistance or remove and test for heat output. Ensure the tightening torque was correct during installation.

Glow plug warning light remains illuminated

This typically indicates a fault in the glow plug system. Scan the vehicle's diagnostic codes for specific error messages related to glow plugs or the glow plug control module.

Pros and Cons

  • Direct replacement for specific Audi, Seat, Skoda, and VW models.
  • Meets OEM specifications for reliable operation.

Cons

  • Specific 7V rating may not be compatible with all diesel systems.

Setup, Compatibility & Care

Compatibility: This glow plug is compatible with various VAG (Volkswagen Auto Group) vehicles, including AUDI, SEAT, SKODA, and VW models, with OEM part numbers N10579803 and N10579805. Cross-reference part numbers include BorgWarner (BERU) CGP003 and NGK CZ304. Always verify fitment with your vehicle's specific make, model, year, and engine code.

Installation: Installation requires removing the old glow plug and screwing in the new one. Pay close attention to the specified tightening torque range of 6 Nm to 10 Nm to prevent over-tightening, which can damage the cylinder head, or under-tightening, which can lead to poor sealing. The fitting depth is 30 mm.

Care: Glow plugs are not user-serviceable components. Their lifespan is dependent on engine operating conditions and electrical system health. Regular engine maintenance, including checking the electrical system, is recommended to ensure optimal glow plug performance.
