Hy , i’ve bought recently a Octavia Vrs 2 2.0 Tdi Cega Engine code ,

After the car sits for like 2-3 weeks , it won’t crank the first 2 times and after that starts roughly and starts smoking and like wather coming out of the exhaust continuously 

First time i changed the spark plugs oil and filters , the problem disappeared 

After 2 weeks it did the same thing , started 3 rd time and the smoke came back …. 

This time The mechanic changed The Egr Cooler/Radiator , new timing belt kit wather pump etc 

Drove like new for like 2-3000 km , after that the car stood again for like 3 weeks 

This time the same old thing … started after 2-3 key turns and When it started … again the smoke reappeared …… 

What could cause the problem ? 

Please some help ? Anyone had the same problem ? 

Welcome. A mod will move your post to the MK2 Octavia section. No spark plugs if a TDI.    Was it injectors or glow plugs replaced?

"Wather"? Do you mean "water"? If so, this is pretty normal until the engine heats enough that the exhaust gases stay above 100C to beyond the exhaust exit.
