Anyone had a problem with the heater not getting hot in there S1 ? Now winter is here I've noticed my heater is barely getting warm after 10-11 mile journey to work
Hi, the bag of silica is in the coolant reservoir and it has been known for this to burst and the silica granules block the heater matrix. Think this bag of silica is meant to prolong the life of the coolant. I removed mine - took a couple of minutes. And would rather change the coolant more often than risk a blocked heater matrix. Best of luck.I really hope it doesnt need the dash out as that seems like a big job in small space, which usually means expensive, I will get it scanned to see if that shows what the issue is, I only have the analogue AC not dual zone climate if that makes any difference, I've read a few things online about a bag of silica possibly bursting and blocking the matrix, no idea if mine has one of these but I suppose checking will be a good idea, cheers Phazer
Yeah sounds like the thermostat is all good. Could be a blocked matrix, pretty sure it's a dash out job to replace so worth attempting a flush out first.I had the water pump replaced about 3 years ago with an INA unit, engine temp rises to 90 after a mile or 2 and stays at that all the time, I'm guessing the matrix is blocked
Hi - I’ve not had this issue, but I did get told by a friend with an S1 to remove the little nylon net bag containing white granules in the coolant filler bottle. These bags sometimes burst and the granules flow round the coolant system and block the heater matrix. So check your coolant filler bottle and see if this bag has split. It’s about 3 inches X 1.5 inches in size. If it has split then this is probably the cause of your heater problem.Never got this sorted and now it's cold again and I no longer have the luxury of having my friendly mechanic. My car has virtually no heat through the heaters whilst driving but strangely has plenty heat when idling stationary for a while, in both cases the guage reads a steady 90 degrees. Any advice on if this is still indicative of a blocked matrix or something else would be greatly appreciated. Local garage want £500 to replace the matrix but in my limited understanding if it was a blocked matrix I would get no heat when idling, or am I understanding this wrong ?
