Hi all,

I have a 2017 2.0tdi Q2 with a faulty heater matrix which has been slowly loosing coolant (about 0.5l every 6 months).

We took it to our dealership over a year ago to investigate the coolant loss and we were told it was normal and not to worry about it.

2 weeks ago the HVAC system stopped heating the cabin so we took it in to the dealership again for clear warranty work and they have told us it’s a fault with the heater matrix (which we knew) and said the work carried out wouldn’t be covered by warranty and quoted us over £2500 to resolve the issue.

They have admitted to not pressure testing the coolant system and/or performing an in-depth investigation to what caused the matrix to fail.

They have told us that the repair wouldn’t be covered by warranty and they are only going on the fact that there was a minor coolant leak, derbies in the expansion tank and the HVAC system not giving out any heat.

Has anyone had this heater matrix fault before? And what where your experiences getting it resolved?

p.s. we are a family of engineers and know what is what… ;D
 
Unless you have anything to prove there utter uselessness, then either get it repaired by them or someone outside the dealer network.

If that's how an Audi dealer acted then it's pretty shabby.
 
got the same issue, just picked up a 2018 TFSI Q5 for the misses topped the coolant up as the light came on the other day and now the heating has stopped... not the best time to stop given the requirement of defrosting right now..

Did a scan and it looks like the matrix is blocked/failed... awaiting on the warrenty company getting back to us as the part is on back order
