Thanks Steve, Any thoughts on the only-one-fan turning question?

Thanks Steve, I've asked my son about white smoke & he wasn't clear..... I'll ask again. He has a basic code reader so I'll ask him to do a scan. The only EGR-valve I've touched (Mondeo) had no cooler so I don't get how one could leak? But.... (1)Might Radweld fix it? (2)Is the only-one-fan-turning correct for normal temp? I mean what is the stationary off-side fan? Extreme Temp? Oil-Cooler? Many Thanks again

Hello I'm doing this for my son who is not car-savvy. He's bought this 2003 Quattro TDI that is losing slight/irksome ammount of coolant. (It's too late now to reject it) No obvious leaks or puddles. He's had it looked at by supposed "Audi experts" ....no answer" He tried a Rold "sniffer" tester (to test for cylinder gases in coolant-Head Gasket Failure) ..... It did NOT change colour ....so negative on Head-Gasket failure. I'm thinking..... (1) Possible EGR Cooler??? (2) Through phone-video (at normal engine temp) I could see nearside rad-fan running ....but offside fan stationary....Is this normal??? (3) The car is aged and cheap ..... should he just add some radweld? (4)Would that fix an EGR cooler-issue? (5)Any other ideas???? HUGE THANKS Len
