hi there
golf 1.9td, 93, 240 000km,
Its almost 2 weeks now that when I start my car, i pull the cold weather lever, the idle is really rough, unregular, as if it burps every second or two. Then i press the lever back, at the lower rpm it burps even more..
But if I use the car again later in the day, it doesnt burp that much, only a bit, then its smooth..
I made 275 km of city for 22 liters, which is not really great...
The smoke at idle is white with a tint of blue.
And, the engine makes this noise like "pffffrrrrfffrrrrfffffffrrrrffffrrffffff"
Bad injection? Or glowplug? I dont have the tools to check...
