Fitment Notes
- Always match OEM reference number(s) and vehicle details before ordering. Confirm exact fitment using VIN, engine code, or chassis number if multiple variants exist.
- South African market filtered: M21 diesel variants (324d, 324td, 524d, 524td) have been excluded as non-SA market vehicles.
- Land Rover (STC2253) cross-reference is supplied for catalogue matching; no Land Rover vehicle fitment was provided in the source data.
Installation / Use / Maintenance Tips
- Drain coolant to below the sensor location before removal to prevent spillage onto the alternator, wiring, or belts.
- Inspect the sensor boss and thread in the cylinder head or thermostat housing for corrosion before fitting the new unit.
- Tighten to the manufacturer's torque specification; do not over-torque as the brass/plastic body can crack or strip the housing thread.
- Refill with the correct BMW-spec coolant, bleed the cooling system fully, and check for leaks once up to operating temperature.
- If a diagnostic scan tool is available, verify the live coolant temperature reading rises smoothly from cold to normal operating range after installation.

Good, but minor issues
The build quality seemed impressive and it felt sturdy. When installed, it definitely stayed in the air vent without wiggling or coming loose after quite a bit of off roading and driving over washboards.
I returned this thing and bought the "off roam" competitor because of two reasons:
1) the ball joints don't tighten down hard enough to lock the position of the mount firmly. It grips well when you don't touch it, but if you are trying to put the phone into the mount without both hands, it shifts and moves with minimal pressure. Kind of annoying for me, I feel the ball joints should tighten enough not to budge if given a tiny bit of force or accidental bump.
2) the inner springs of the phone holder started loosening and making an obnoxious vibrating/rattling sound after about a month. Any bump or minor rough surface caused this thing to rattle like loose change in a cup holder IF THE PHONE WASNT IN IT. If the phone was in the holder it didn't do this at all. It started to drive me crazy.
If you can get past these two things it's built well enough and works perfectly fine. I just expect a bit more for $50-$60.
