Constant oscillation of the solenoid regulator valve in the bore creates wear, which can reduce solenoid feed pressure, resulting in various shift complaints in VW/Audi 096, 097, 098, 01M, 01N, 01P units. In addition, wear at the solenoid regulator valve can reduce balance line pressure at the main regulator valve, which will result in low line pressure or no line rise. Sonnax oversized solenoid regulator valve 119940-06K restores solenoid feed oil pressure. Adjustment of the ratcheting end plug on the boost regulator valve may be needed after servicing the solenoid regulator valve. Sonnax recommends the adjustment tool [119940-TL9] for proper adjustment without damage to the plug.

• Oversized valve restores solenoid feed oil pressure
• Hardcoat anodized aluminum valve combats premature wear
• Valve is recalibrated to restore OE pressure specifications
