Keep an accurate eye on engine temperature with the Standard Ignition Engine Coolant Temperature Sender TS-427. This sender threads into the engine's coolant passage and reports coolant temperature to the vehicle's gauge or warning circuit, so the dash reading tracks what the engine is actually doing. It drops in as a direct-fit replacement for the 1989-1991 Audi 100, 1989-1991 Audi 100 Quattro, 1989-1991 Audi 200, 1989-1991 Audi 200 Quattro, 1984-1988 Audi 5000, and 1986-1988 Audi 5000 Quattro.
- Job: Senses engine coolant temperature and sends that signal to the temperature gauge/warning circuit.
- Direct fit: Designed to replace the original sender on the listed Audi applications.
- Signs it may need replacing: An erratic, stuck, or dead temperature gauge reading. If a failed sender is the cause, this replaces it; diagnose the circuit before ordering.
Because temperature readings can also be affected by wiring, the gauge, or the cooling system itself, confirm the sender is the fault before replacing it.

Frequently Asked Questions
What does the TS-427 do?
It senses engine coolant temperature and sends that signal to the vehicle's temperature gauge or warning circuit, so the dash reflects the engine's coolant temperature.
Which vehicles does it fit?
The 1989-1991 Audi 100, 100 Quattro, 200 and 200 Quattro, the 1984-1988 Audi 5000, and the 1986-1988 Audi 5000 Quattro. Check the Buyer's Guide tab to confirm your vehicle.
What part numbers does it interchange with?
It cross-references 034919369B, WT699, SW4826, TS6032, 035959481B and 035959481C.
What are signs this sender may need replacing?
An erratic, stuck, or non-responsive temperature gauge reading can be a sign. Wiring, the gauge, or the cooling system can cause similar symptoms, so diagnose the cause first.
Will replacing this fix my temperature gauge?
If a failed sender is the cause of the faulty reading, this replaces it. Confirm the sender is at fault before ordering, since the wiring or gauge can also be responsible.
