OE 823959481A — Temperature Switch for Audi

Start from the code cast or printed on the part you are removing — that is the authoritative source. If it is illegible, use the Applications table on the closest electrical & sensors reference and narrow by build year. Send photos and we will cross-check the number for you.

Yes, if the alternate shares the same engineering envelope. Shortlist candidates from the Related OE References table, then check bolt pattern, electrical pinout and material grade. A difference in any of those three means it is a different part, not a substitute.

Standard minimum order is 10 pieces per part number. Mixed orders that combine 823959481A with other electrical & sensors references are welcome — that is how most clients fill an LCL or FCL container without over-stocking a single line.

Incoming batches pass a dimensional check, a material look-up against the electrical & sensors specification, and a visual inspection for finish defects. Critical dimensions are measured per carton and the photographs are archived against the order number.

OEM means the part was produced for the vehicle maker's assembly line; aftermarket means it is made independently to the same engineering drawing. For a temperature switch the practical gap is usually tooling age and packaging rather than fit, provided the tolerance class matches.

Position depends on the platform. On most Audi applications the temperature switch sits on the electrical & sensors assembly and can be reached from the engine bay or the underbody without removing the dashboard. Torque figures and disassembly order are given in the workshop manual for each model.
