038906018S Audi Modulo di controllo ECU motore – Originale usato e collaudato

Descrizione

Il 038906018S è un modulo originale di gestione del motore diesel della famiglia motori VAG Group TDI 1.9 litri — uno dei motori diesel più ampiamente prodotti nella storia automobilistico europea, installato su un'ampia gamma di Audi, Volkswagen, SEAT and Škoda models. This ECU manages all key diesel engine functions for the applicable TDI variant, including injection quantity and timing, common-rail pressure, EGR valve operation and turbocharger boost control.

The 1.9 TDI ECU operates within a Bosch EDC or Siemens VDO architecture depending on engine code, reading data from the fuel rail pressure sensor, boost pressure sensor, EGR position sensor, crankshaft sensor and intake temperature probe to compute precise injection parameters. This close management of injection events is central to the 1.9 TDI’s characteristically strong low-speed torque and its long-standing reputation for economy and reliability across high mileages.

On 1.9 TDI-engined Audi models, ECU-related faults often present as the engine entering limp mode with power and boost cut above 2,000 rpm, intermittent starting failures in cold weather despite functional glowplugs, stalling at idle under load conditions, or repeated fault codes for EGR or boost deviation that reappear after the hardware has been inspected and found serviceable.

This is a genuine used OEM unit sourced from a 1.9 TDI-engined Audi and tested before listing. Used diesel ECUs from the TDI range require programming and immobiliser adaptation using VCDS or equivalent VAG-compatible diagnostics. Cross-reference this number with your current ECU and arrange professional installation.
