Product Description
Coolant Hose 06E121030B For Audi A6 C7 A7 3.0T — OEM Engine Oil Cooler Pipe
The Coolant Hose with OEM reference number 06E121030B is a verified direct-fit replacement for a wide range of Audi vehicles equipped with the 3.0 TFSI V6 supercharged engine (engine code CGXB) as well as the 2.8 FSI V6 naturally aspirated engine. This pipe is a critical component of the engine oil cooler's coolant circulation system, responsible for transporting coolant to and from the oil heat exchanger to maintain optimal engine oil temperatures.
The engine oil cooler uses engine coolant to regulate the temperature of the engine oil, preventing it from overheating during high-load operation and ensuring it reaches operating temperature quickly in cold conditions. A leaking or blocked coolant hose can lead to oil overheating, reduced lubrication performance, and potential engine damage.
This OE-spec replacement coolant hose is manufactured to original equipment standards, ensuring a perfect fit and reliable sealing. It is a genuine Volkswagen Group part with HS CODE 40093100 and is backed by a 2-year international factory warranty.

Common Failure Symptoms
| Symptom | Description |
|---|---|
| Coolant leak | Visible coolant puddles under the vehicle or around the engine oil cooler area |
| Low coolant level | Repeatedly needing to top up the coolant reservoir |
| Engine overheating | Coolant loss leads to inadequate cooling |
| Oil temperature warning | Engine oil temperature rising above normal due to insufficient oil cooling |
| Coolant warning light | Dashboard warning light indicating low coolant or cooling system fault |
| Failed non-return valve function | A small non-return valve is fitted in the coolant hose system; flow must only go towards the reservoir and be blocked to the engine |
⚠️ Ignoring a failing coolant hose can lead to:
- Engine oil overheating and reduced lubrication
- Premature engine wear and potential failure
- Coolant loss and engine overheating
- Costly engine repairs

Installation & Maintenance Recommendations
⚠️ IMPORTANT: Coolant system work requires mechanical competence and proper coolant handling. Professional installation recommended.
Installation Guidelines (Reference Audi workshop manual for complete steps):
- Safety first — allow engine to cool completely before starting work
- Drain the cooling system — capture coolant for proper disposal
- Locate the coolant hose at the engine oil cooler — follow the routing from the oil cooler to the coolant system
- Remove the old hose — note the position of any quick-release couplings, clamps, or O-rings
- Compare the new hose with the old unit — verify part number (06E121030B) and routing match
- Inspect all connection points for damage or debris
- Install the new coolant hose — ensure all connections are fully seated
- Secure any clamps or quick-release couplings
- Refill cooling system with the correct Audi-approved coolant (G12evo/G13 spec)
- Bleed the cooling system to remove air pockets — critical for proper cooling
- Start engine, bring to operating temperature, and check for leaks
- Verify heater operation and proper temperature gauge reading
Pro Tips:
- If replacing the coolant hose, consider replacing the coolant at the same time
- Use only Audi-approved coolant — never mix different coolant types
- When replacing the hose, inspect the non-return valve function if applicable
- Check all coolant hoses and connections for signs of wear or damage
