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 ?

Post does not make sense. If it is a TDi how can you change spark plugs!

Burning diesel or petrol in an engine creates water.

Starting from cold creates water vapour and is more obvious especially when the car has been standing.

You may not have a problem.
