306 smell, could it be the matrix?

Post by pug_owner2002 » Wed Nov 28, 2007 9:24 pm

Hi All,

I have got a 2001 X reg 306 1.4 that has don 97k, I have started to notice a smell inside the car which is worse when the blower is not running, the smell to me is like a curry kind of smell.
Could this be as I suspect, the matrix starting to fail?
I have not checked the water level yet to see if it has gone down as the engine is still hot, I will check it in the morning.

Any help/coments appreciated.

Yes, sadly, that is the first sign :(

However, having said that, they can go on a long time smelling a little and not leaking any significant amount of coolant.

All my Xantias smell a bit but only briefly. My Activa was worse at the start of winter. It seems where the flaps were closed against the matrix all summer, a bit of coolant built up and smelt for a bit. Touch wood, it has all gone off now.

I understand doing a 306 matrix is nearly as much of a task as a Xantia. The dash has to come right out :twisted:

Thanks Citrojim,

You have confirmed what I suspected.
I'll have to see how it goes and potentially get it replaced. :cry:

Glycol anti-freeze smells sweet - not like curry.

There were a number of posts on curry smells some time ago and apparently it can be a bacterial contamination of the matrix - which can be shifted with a specialist product - Halfords?

More common with air conditioning.

Other signs of leaky matrix is misting of the screen on startup (heater on etc - damp air condenses on screen)

If it is leaking try some K-Seal. I added some to my Xantia which showed signs of a leaking matrix so i waited until after the water pump/cambelt was done and added a bottle, it doesnt mist the screen up anymore, or smell. It's worth it for a tenner to save the hassle.

Hi all,

Thanks for the replys.
It's been a couple of years since I used the air con cleaning stuff from halfords so it probably is worth me buying that and seeing if it helps.
I will continue to keep an eye on the coolant level as it does not appear to be using water, if it does though I think I'll go down the route suggested by Xantiaman and try some K-Seal.

Thanks again!
