Rough running, hesitation under load and exhaust noisy. No fault codes stored, live data reading
check showing the Vanos solenoid units not working correctly, suspect vanos sticking.
The fault was cured by carrying out a 1 hour Forté Advanced Formula Motor Flush and a 5 mile road test.
The oil and filter was then replaced and live data readings rechecked showing the vanos solenoids
were working correctly and the engine running smoothly.
Thanks to Rich at Auto Renovate MOT & Service Centre in Felixstowe, Suffolk.
Forté's Technical Helpline receives over 300 calls per month. This blog shares solutions for garage workshops on common driveability concerns that can be quickly and effectively treated. The vast majority of those identified are caused by fuel and oil borne contamination formed by natural degradation or via the combustion process. This is a fact of life for internal combustion engines where fossil fuels and oils are used.
