Volkswagen Passat - '99 Passat TDI Heater issue - TheAceOfSpades

Hey guys,

I've got a '99 1.9TDI Passat with Climate Control, with a strange fault. Everything is fine with the temperature on low, but as soon as i change it to any kind of heat, i get a vapour and that 'hot water' smell come through the windscreen vent. Although the temperature gauge doesn't work, the cars not over heating, as i drove it 200 miles yesterday with no problem.

Any suggestions as to what it could be?

Many thanks in advance,

Danny!

I would think that your heater matrix is leaking slightly.

When hot, it will vaporise immediately giving you the smell.

It's a dashboard out job, so you might want to try radseal or some other radiator sealer first.
