Heater Matrix Replacement

We are carrying out many Heater Matrix replacement’s at the minute. I assume with the weather being as cold as it is, customers are noticing the lack of heat from the blowers a lot more. Heater matrix faults are common within the following vehicles: Mk7 Golf, Audi A3, Seat Leon and Skoda Octavia.
They all suffer with a problem where the heater matrix blocks up. The core in the heater matrix is very very thin so any sediment and contaminants in the antifreeze system unfortunately causes the heater matrix to block.

The first problem you will normally notice is the blowers on the passenger side are warm, but the driver’s side are cold. This is because sediment blocks the far end of the heater matrix which blows cold air to the driver’s side of the dashboard. Other signs your hater matrix has gone are;

  1. You’re fogged out…
  2. There’s a sticky sweet smell…
  3. You’re going through a lot of coolant…
  4. Your vehicle has overheated.

Again, a very common problem which we are seeing lots of at the minute. Probably more noticeable now with such cold weather!

As always we replaced with a brand new Genuine Heater Matrix replacement as shown in the pictures  on our facebook below!
