Heating issues

[Charcross]

Hi all wonder if someone can help. I have a 2013 Leon 1.6 tdi. Once the cars up to temperature and I go to use the heaters the air blown out is luke warm and doesn’t get hot. I’ve been told to do a matrix flush but wondering if anyone has any input on this please help.

Without writing you an essay, if you search for Heater Matrix, you should see previous threads on the issue. I suspect that a flush would not help and a replacement matrix is needed.

Okay thank you I will have a look.

Heater matrix flush works as a 'temporary' fix.
Flushed mine something like 4 or 5 times - hoping eventually it would need less and less flushing but to no avail.
Really need to whole system flushing and new heater matrix.
You can easily get to the matrix in the passenger/LH side of the centre console.
No need to remove the dash - or any pipes in the engine bay.
