Lambda 1.010, no faults or fault codes found. Forté Specialist Injector Cleaner and Forté Advanced Formula Gas Treatment added and extended road test carried out, fault not cured.

Problem with a BMW Z4 2.0L 2007 50k

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.

Lack of power and running in limp mode, suspect fault due to build-up in the Diesel Particulate Filter (DPF). Diagnostic check carried out and showing 77% soot loading in the DPF.

The fault was cured by adding Forté DPF Cleaner & Regenerator into the fuel tank and carrying out an extended road test.
