EGT Probe — Exhaust Gas Temperature Sensor — Original OEM Part 059906088BB

Original exhaust gas temperature (EGT) sensor for V6 3.0 TDI diesel engines in the VAG group. It monitors the exhaust gas temperature before the turbocharger and particulate filter, controlling DPF regeneration. A faulty probe causes an exhaust gas temperature sensor error, limp mode, DPF clogging, or failed regenerations. Part removed from an Audi Q7 with no accident history, fully functional.

Catalog number (OEM): 059906088BB (059 906 088 BB).

Fits, among others: Audi Q7, A6, and A4 with 3.0 TDI engines, as well as other VAG group cars with a V6 TDI engine from the 059 family, where a probe with this number is used.

Condition: used, fully functional.

Several EGT probes with different numbers are used in a single engine, depending on their position in the exhaust system — before purchasing, compare the full catalog number with the sensor in your car.
