Core Product Features
🔧 ECU Coding & Programming Required After Installation: This electromechanical steering rack features a fully integrated electronic control unit (ECU). Installation requires factory online programming, Component Protection release, and steering angle sensor initialization after fitting. Ensure your technician has access to professional diagnostic tools like Audi ODIS (with online GeKo access), Autel Maxisys Ultra, or Ross-Tech VCDS before purchasing. Mechanical fitting is a direct bolt-on, but software flashing is the buyer's responsibility.
⚙️ Precision Mechanical Rebuild: Fitted with premium, high-strength internal guide bushings, heavy-duty internal bearings, and OEM-spec synthetic grease. The internal belt and rack-and-pinion clearings are pre-loaded to exact factory tolerances — completely eliminating steering play, steering wander, or loose center feel.
📊 100% Bench & Dyno Tested: Every single unit undergoes advanced electronic testing on specialized load benches, verifying EPS motor torque curves, sensor digital CAN-bus feedback loops, and internal electrical resistance parameters under simulated maximum vehicle weight. Hardware is 100% guaranteed sound.
🛡️ Save Up to 70% vs. Dealership Pricing — 24-Month Warranty Included. No core charge. No messy core returns or return deposits. Just a premium bolt-on replacement backed by our industry-leading warranty.
Frequently Asked Questions
Q: Is this electric power steering rack compatible with Left-Hand Drive (LHD) models?
A: No — this specific unit is engineered and manufactured exclusively for Right-Hand Drive (RHD) vehicles. It will not physically fit or function on LHD cars due to the steering gear casing and input shaft pinion orientation.
Q: Do I need to send my old steering rack back (core charge)?
A: No core return required. Keep or dispose of your old unit as you see fit — no return shipping fees or deposit holds.
Q: Can an independent workshop install and code this right-hand drive rack, or must I go to an Audi dealer?
A: Any independent specialist or workshop equipped with proper diagnostic programming gear (like ODIS with online access, or advanced Autel) can successfully flash, remove component protection, and calibrate the unit. An authorized franchise dealership is not mandatory.
