Coolant from a leaking valve won't end up misting the screen, but a leaking matrix will.

can smell that rubbery water smell. but the water under the carpet got me thinking both have gone ???

Will check it all tomorrow just a nightmare of a job with the M52 conversion

They might well have, or the misting could be rain water coming in from the scuttle.

Any rust pics yet ?

Ours , 318is did it tonight on the way back from Southampton on M3 ,man was it a pain! Lucky I had company to wipe the windscreen. It is her car so she got to wipe. Steaming up big time when driving fairly quickly then on North Circ it wasn't too bad. Carpet had been damp last week so maybe it is in the soundproofing. Hopefully, as she doesn't want to go down the matrix route again.

when did you change the matrix last then??

Post Sat Dec 07, 2013 8:58 pm

The year before last when we weren't getting any heat. Weirdly last week we just put 4litres of antifreeze in and bled it good and proper. You would think that the antifreeze smell would come with the steam if it was the matrix.

Changed my anti freeze 2 weeks ago

mine smells of the rubberie water smell and lossing water from the rad so i have a problem

fingers crossed its just the matrix and not the heater valve or both

Try some K seal, about £10 from motor factors
We had a Hilux with a leaking Matrix, and 3 years on the cooling system is still OK and heater still working
Don't bother with other products, just the K seal which should sort the leak and save you ££ on matrix replacement which is a fortune on most cars

And the reason is?

its water somewhere inside, floor, bulkhead, rear floor bungs, could be anything

i had it a little in my old 318is- when i had the windscreen changed, the bottom corners of the screen seal had little splits in the middle of the seal- would never of found/seen had the screen not been taken out, new seal, all was well

1st thing id check- is lift up the rear floor pan carpets feel right under, see if theres any damp/wet in the foam backing

or it hasnt been bled properly when you changed the fluids,
and something's gone pop due to trapped air....

Looks like the carpets were wet, from the door seal I guess. Gave the windows a good clean inside. All dried out now and no steam. Well just the usual amount.
Thanks

E30 carpets can hold several litres of water, and still be dry on the inside surface. Only way to dry it properly is to take it right out and hang it vertically by one corner, when the water will rapidly drain to the lower corner where it can be wrung out.
If it's wet, and you do take it out, you may as well give it a good session with a pressure washer before you dry it.
