Specially calibrated for mid-lifecycle Left-Hand Drive (LHD) VAG MLB platform passenger cars. The original equipment part number 4G1423055BG is an engineering update introduced heavily for 2014, 2015, and 2016 production runs of the Audi A6/Quattro, A7 Sportback, and executive A8/S8 premium sedans.This specific component is tailored strictly for vehicle configurations utilizing the standard electronic speed-sensitive Servotronic power steering matrix. It ensures an identical digital signature match for the onboard network gateway, entirely removing any module handshaking conflicts common in older factory steering revisions.

(Note: Please verify your factory build data sheet excludes the PR-1N8 Dynamic Active Steering option before purchasing).

Within Audi’s official parts catalog hierarchy, 4G1423055BG marks a critical turning point where factory hardware was upgraded to overcome early failure rates.If your vehicle’s physical steering rack casing or diagnostic scan displays obsolete legacy numbers—such as 4G1423055Q, 4G1423055AA, 4G1423055AH, or 4G1423055AN—this 4G1423055BG unit provides a completely validated, updated direct retrofit solution. It features superior internal torque-angle sensor isolation compared to those older variants. Conversely, for late-lifecycle replacements, the BG platform was later succeeded by newer part allocations like 4G1423055BQ and ultimately condensed into the 4G1423055EA generation.
