2012-2015 BMW 320i 2.0L I4 Turbo N20
Description
The pressure drop across the intercooler exceeds the expected threshold, indicating a restriction or leak in the charge air path.
Symptoms
- Check Engine Light
- Reduced boost pressure at intake
- Turbo works but power is still low
- Hissing noise from intercooler area
- Oil residue around intercooler hoses
- Poor high-load performance
Common Causes
- Intercooler internal blockage
- Intercooler core damage
- Charge pipe leak or crack
- Intercooler hose clamp loose
- Debris impacting intercooler core
Diagnostic Steps
- Measure pressure at turbo outlet and throttle body
- Pressure test intercooler system
- Inspect intercooler hoses and clamps
- Check intercooler core for physical damage
- Look for oil contamination in intercooler
Repair Notes
Replace or repair intercooler. Tighten or replace charge air piping. If oil contamination is excessive, check turbo shaft seals.
