BMW VANOS Repair in Chattanooga

VANOS is BMW's variable valve timing system, and when its solenoids or seals wear out you'll often feel it as rough idle, hesitation, or lost low-end power. At Inline Autohaus in Chattanooga, we diagnose VANOS faults accurately and restore your BMW's smooth, responsive performance.

• Rough or uneven idle
• Hesitation or stumbling under acceleration
• Loss of low-end power or poor fuel economy
• Check-engine light with VANOS or camshaft timing codes

Over time VANOS solenoids get clogged or fail electrically, and the internal VANOS seals harden and lose their ability to hold oil pressure. Either issue disrupts valve timing, hurting smoothness and power. Cleaning or replacing solenoids and resealing the VANOS units restores correct operation.

1. Diagnostic scan and live-data review to confirm a VANOS fault
2. Inspection of solenoids and oil supply
3. Cleaning or replacement of solenoids and reseal as needed
4. Re-test to confirm timing and smooth operation
