Problem with a VW TRANSPORTER 2.5 TDi 2005 100K

VW TRANSPORTER 2.5 TDi 2005 100k

Lack of power; fault due to a blocked Diesel Particulate Filter (DPF).

The fault was cured by removing the DPF and pouring 2 x Advanced Formula Diesel Treatment into the DPF, soaking overnight then rinsing with hot water and drying with compressed air. The vehicle was then treated with Diesel I.M.V. Cleaner as per instructions, Clean & Protect carried out and DPF Cleaner & Regenerator and Advanced Formula Diesel Treatment added into the fuel tank. The vehicle was then taken on an extended road test to allow regeneration of the particulate filter.

Problem with a VW POLO 1.4L 16v 2000

VW POLO 1.4L 16v 2000

Failing MOT emissions test due to high CO and low lambda readings. Coolant temperature sensor and oxygen sensor before catalytic convertor replaced; fault not cured with the emissions test still showing high CO and low lambda readings.

The fault was caused by a faulty EVAP canister purge valve. After fitting a new EVAP purge
valve, the emissions readings were restored and emissions re-test passed. It is also recommended to use Clean & Protect (Advanced Formula Motor Flush and Oil System Protector) to clean and maintain the oil system and add Advanced Formula Gas Treatment to the fuel tank to clean and lubricate the fuel system.
