heater matrix

Hi, I have a 64 plate Leon FR 2.0 TDI (184). My coolant seems to disappear to which several mechanics have had a look, however recently I have also had a low engine oil light appear. They’ve pressure tested the expansion tank to which it’s held pressure. They have done the fluid dye test...

Hi all, can anyone point me in the right direction for help with my mk3 FR 2.0 TDI. Heat went about a year ago on drivers side of climate control. I left it as I had heat from passenger side but thats now gone. So no heat at all. Car gets up to temperature as it should. Can’t seem to see a...

Hi, new member here. Had a search for a similar issue and found many heater issues but nothing like I am experiencing on my 2013 Leon 1.6tdi. From this forum, I am thinking about buying a diagnostics tool (carista etc.) to see if I can work out the issue. Is this possible? My Problem...

Having a heating problem with my Leon, I've seen threads on this before but nothing as specific as mine. 2 days ago I had a low coolant warning on the dash, checking it revealed the coolant tank was almost empty. It was last checked a few weeks ago, so is very odd to drop so much so suddenly. I...

Hello all. I have a 2007 Leon FR & the coolant warning light came on Monday. I filled the tank up & it came on again after only a day. I could not see any visible leaks until this evening when I jacked up the car & had it running. At first, there were no leaks until I put the heater on warm &...

Hi guys, anyone know what type of hose pipe to use to flush the matrix from the firewall side? Is it just a general garden hose or something a bit bigger

Hi guys, I have a 2014 Leon FR (mk3). I need to remove the heater matrix. I’ve been advised that this can be done without removing the dashboard. Is this true? Apparently it can be accessed and removed from the passenger footwell area. Any advice please guys?

Hello All, Quick note to say thanks to all who contribute on here. 2014 Seat Leon ST FR 2.0 TDI 184 with guess what - a blocked heater matrix! I win a prize. Had the car for 2 years and love it but currently not best pleased. LOTS of reading up and `my car did that` have helped me understand...

Hi all. New to the forum as I bought a 64 plate Leon FR 184 2.0 diesel. Like the title suggests, a massive thank you to this forum. I bought my Leon from Evans Halshaw Ford Grantham. Had a couple of issues with it, and one of those issues this forum has helped fix. So thank you very much...

Hi - Anyone know where to get either the bottom or top heat echanger (matrix) tobe clamps or an aftermarket alternative?

My Leon Cupra 280 seems to take a while to get up to heating temp. Where I must be the Driving car in excess of 10 mins. Then it heats up fine In the meantime, cold air con works fine, and works fine when up to speed. While the car is warming, there is a point where the heaters blow warmish...
