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;
- You’re fogged out…
- There’s a sticky sweet smell…
- You’re going through a lot of coolant…
- 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!
We have been undertaking plenty of ASNU Classic GDI injector cleaning recently in the workshop. We advise getting your injectors tested and cleaned along with a carbon intake valve clean. These two jobs go hand in hand. When your valves get a build up of carbon, they in turn start to block the tiny holes on the injectors. When the holes on the injectors get blocked up, the spray pattern becomes irregular between each injector which causes the vehicle to misfire/run lumpy along with various other issues.
The ASNU Injector Cleaning system allows the us to visually examine the injectors, on an individual cycle or in sequential mode. We can then compare the injectors performance under a range of simulated Millisecond & RPM driving cycles, already programmed in to the ASNU system.

Here’s a slow motion video showing the spray pattern on 4 injectors. As you can see the spray pattern is exactly the same on each injector. This shows that the holes on each injector must be clear of dirt particles.

The injectors also get a flow test. To do this, test fluid is pumped through the injectors to make sure they allow the same measurement through. We can safely allow a 10% difference between the least measurement, and the most. As you can see on the picture below, this test has shown each injector is working to exactly the same level.

Once they come out of the ASNU Classic GDI Injector Cleaning system, they sit in the built in Ultrasonic Cleaning Bath. As a result, this will clean the outside of the injector and pulse through any particles of dirt.
In conclusion this is just one service carried out by ourselves. One of many that our current and future customers may not know about. Find out more on our services page here: https://www.northeastautotech.com/additional-services/
