Engine Cutting Out, Tank Pressure Valve N80

[Raitis]

Hello for everybody!

I have a Passat 2001 1.8T B5.5. It is acting very strange. I can't remember it doing in past, maybe I have not notice it BUT on trafic lights after a 10-15 min of driving it runs a half of a minute on 800 turns and then could cut out completely,as if sudden fuel cut or some like that. Now I have diagnosed it and a computer said fault on Tank Pressure Valve N80 (short to ground). They are 70 pound at dealers which is not bad but I do not think that it will salve the problem, althought I could be wrong. Have anybody experienced something like that and help with advise?

Thanks!
