Hi guys, I don’t want to go over old ground with this and I have learnt much from other threads on this issue but have one unanswered question. As the title suggests I have the heater matrix silica bag bursting issue on my 2014 2.0 TDI, confirmed by my local Skoda dealer. The only issue I have at present is no warm air from the passenger side heating vents, no fluctuations in engine temperature at all, no warning lights. The dealer wants £1200 to replace the matrix and header tank plus flush, eight hours labour. I have contacted Skoda UK (prior to Covid) and they weren’t interested saying they couldn’t answer technical questions and I would have to contact my dealer. My question is, will the silica within the coolant cause other issues eventually or is the worst outcome a crap heater?! Thanks in advance, Jonathan.
