BMW 530D 3.0L 90K
Poor starting when hot or cold. No fault codes stored. Suspect sticking injectors or piston rings.
The fault was cured by carrying out Clean & Protect; 1 hour Advanced Formula Motor Flush carried out adding Oil System Protector to the new oil and 2 x Advanced Formula Diesel Treatment to the fuel tank and an extended road test.
Thanks to Dave at Stonebridge Auto's in Great Yeldham, Essex.
