Thermostat Mahle or OEM Volkswagen

I’ve installed Borg Wagner thermostats and those always failed until I installed a Mahle one which never failed. For some reason any other brand will get stuck open and the engine will never get up to temp.

I used Mahle, but I got lucky I got the German-made one (afaik now most are made in Italy). It was NOS so I expect the electrical heater (to open early) to be defect. It's been 3 years without issue though.

I used oem bmw coolant and a mahle thermostat.

Mahle is an OE supplier for bmw, go for it

Mahle is the OE replacement for the thermostat, the Chrysler logo is on the part but sanded down. Autozone sells them with PT# TI23695 I just replaced mine last weekend.

I had a brand new mahle one with the connector wired in reverse for constant. Kept blowing a fuse. Returned it for a replacement and worked fine.

Mahle is an OEM supplier and is on stock in Amazon.

Hatte auch schon ein Mahle Thermostat das kurz nach eimbau defekt war. Dannach ein Originales von BMW rein und seit dem wi3der keine Probleme.

Original was stuck open, replaced with new VW which now appears to be stuck closed. ????. Fortunately I have recently acquired a new OE thermostat on clearance for jollies.

Last week changed the thermostat on my 1.9 tdi 66kW to a Mahle TX 15 87D (11€), it was fine for the first two days, then the temps started dropping again.
