Heater Matrix prob???

[CooperS230]

I am suspecting that I have a problem with my heater matrix as the passenger footwell is damp and there was steam coming out of air vents... Has anyone else suffered the same problem and if so how much did it cost to repair?

Cheers,
Steve..

I've had a heater matrix fail in another car (twice in a row ) and steam from vents, steaming up windows, wet carpets and a strong smell of coolant are sure signs. Can't help you with the cost in a MINI though.

Battery & battery tray has to be removed on a One/Cooper (also probably ECU) but I think only the Air cleaner if a Cooper S, to gain access to the matrix pipe unions on the bulkhead, then the matrix can be removed from inside the passengers footwell (behind a matrix cover) 3 Torx screws hold it in. At least the dash does not have to come out like some cars so labour price should be more reasonable...........or if you are a reasonably confident DIY mechanic you could get the Haynes manual for the full details.
Just noticed your an R56 2nd Gen but I would think its a similar set up & must be under warranty?

Hi, do you know if this was a faulty heater matrix?
Is your car modified?

Why DIY take it back to the dealer ?

I have a 03 cooper s and suspect that my heater matrix has gone again this morning for the 3rd time since I bought my mini. It may be a sign of a more serious problem. i.e. cylinder head problem. I will be getting in touch with mini and hopefully they will do something about it.

Just to let you know. My heater matrix has now been repaced by the Dealer for the 3rd time in 18months. It was replaced free of charge but they have no idea why I have had to have 3 replacements. Anyway depending how old your car is you may get the job done for free.

We have recently purchased a 2005 cooper and since Jan2012 we have had to replace two heater matrix All the heaters had the same scuff marks along the width and is obvious to anyone with normal eyesight that it is a manufacturing problem that bmw chose to ignore They will repair the problem time after time but they are reluctant to repay any monies to you that you have spent to rectify your problems Why they are shielding Valeo the manufacturer i dont know perhaps its a subsidiary of bMw
