Had a TPMS error flag up on my 2019 XV, diagnostics show that the Offside front sensor needs replacing.
Spoke to my not so local dealer and no stock expected in UK till end of December, and priced at just short of £70 per sensor. 
Has anyone had their sensors replaced with a non Subaru TPMS sensor and did it work fine, if so which ones did you buy? 

Cheers

The TPMS sensors have batteries that only last 5 to 6 years and which aren't garage replacable so you have to buy a whole new sensor - a real rip-off. Subaru don't make these sensors, they re-badge Schrader ones and mark them up. Do your own research, but I believe the Schrader 3076 is probably the one used on used on recent Subaru - they are half the price of the 'genuine' Subaru ones. My go to garage says they 90% sure they'll be able to program the one I've bought as a test when I get it serviced at the end of the month - the nearest Subaru dealer want £500 to change all 4 !! BTW if the battery(s) are fine but on the way out, they will still trigger the TPMS warning when the weather is colder than 10C as I've found out with the recent mild weather.
