Where a repair range is shown, treat it as a rough estimate. Actual pricing depends on the vehicle, diagnosis, parts required and repair scope. Message Auto Imports for an accurate estimate.
HOW WE DIAGNOSE BMW 335I OIL LEAKS PROBLEMS
Different faults can create similar symptoms. Our diagnostic process can include:
- Scanning the applicable control modules for stored and pending faults
- Reviewing live data under the conditions that reproduce the complaint
- Inspecting the affected mechanical, electrical or fluid system
- Pressure, leak, electrical or mechanical testing where required
- Confirming the exact engine, transmission and system configuration
- Verifying the failed component before repair
This approach separates a known model pattern from the actual fault on your vehicle.
SERVICE AT AUTO IMPORTS
Once testing confirms the cause, we build the repair around the failed component and inspect related parts where labour overlaps.

BMW 335I OIL LEAKS EDMONTON (N55 ENGINE) FAQ
Q: What causes oil leaks on a BMW 335i N55?
A: The most common sources of oil leaks on the 2011–2015 BMW 335i N55 engine are the oil filter housing gasket, valve cover gasket, and timing cover seals. The oil filter housing gasket is particularly notorious — it fails with age and heat cycling, causing oil to pool under the front of the engine.
Q: How much does it cost to fix a BMW 335i oil leak in Edmonton?
A: At Auto Imports, oil filter housing gasket replacement on the N55 typically costs $600–$900. Valve cover gasket replacement runs $800–$1,200. We often recommend addressing both at the same time to reduce future labour costs. Contact us for a specific quote.
Q: Is it safe to drive a BMW 335i with an oil leak?
A: Small leaks may be manageable short-term, but any oil leak on a BMW N55 should be addressed promptly. Oil on hot engine components creates a fire hazard, and if oil level drops significantly, catastrophic engine damage can occur. We recommend inspection at the first sign of oil under the vehicle.
Q: Does the BMW 335i N55 have the same timing chain problems as the N20?
A: No. The N55 single-turbo engine has different characteristics than the N20. N55 timing chain concerns are less acute, though chain stretch can occur at very high mileage. The N55’s primary issues are oil leaks, charge pipe failure (the plastic turbo pipe cracks and causes boost loss), and electric water pump failure.
Q: What is the BMW N55 charge pipe and why does it fail?
A: The charge pipe connects the turbocharger to the intercooler. On the N55, this pipe is made of plastic and can crack under the pressure and heat cycling of turbocharged operation. When it fails, you lose boost pressure and experience sudden power loss. Replacement with an upgraded metal pipe is the permanent fix. Related Services
