Newer platform and electronics; not interchangeable with 8U.
Audi Q3 RHD Part Numbers and Rack Families
These complete references are identification guides collected from specialist catalogues. A shared base number does not prove interchangeability: confirm every character on the original label, the VIN, right-hand-drive specification, connector count, PR code and software before supply or fitting.
Q3 8U RHD references
5N2 423 055 A; 5N2 423 055 AX. Other 5N2 423 051, 5N2 423 058 and 5N2 423 062 variants exist, so the complete label is essential.
Q3 F3 RHD references
5QC 423 051 C; 5QC 423 055 B; 5QC 423 055 C; 5QC 423 055 D; 5QC 423 055 DX; 83C 423 053 A; 5QC 423 053 C. Published ATG references: ATGJ41181RB and ATGJ41601RB for different ratios.
Standard, Dynamic and Lock-to-Lock Differences
Use chassis generation and original data. A facelift registration date alone is not enough.
Safety first: never force an incompatible rack through calibration. The wrong steering type or travel can prevent end-stop learning and leave steering-angle faults.
Common Audi Q3 Electric Steering Faults
Heavy or intermittent steering
Assistance may disappear, return after restarting, or become heavier in one direction.
Warning lights and stored codes
Enquiries include C10AC07, C10ACF0, B200000, 03803 and steering-angle or end-stop faults. Diagnosis is required before condemning the rack.
Noise, play or water ingress
Mechanical wear, corrosion, damaged boots, seals or electronics can cause noise, looseness or unreliable assistance.
Calibration after fitting
Wheel alignment, centred track rods, steering-angle checks and lock-stop learning may be required.
Our Repair and Identification Process
Frequently Asked Questions
Can you identify it from the registration?
It helps, but VIN and rack-label photographs are normally required because mid-year changes are common.
Will it need programming?
Many correctly prepared racks avoid full dealer programming, but some require coding transfer, initialisation or end-stop learning.
Do you serve trade customers?
Yes. Garages, workshops and resellers are welcome, as are private customers.
What warranty applies?
Reconditioned steering work includes a 12-month warranty. For resellers, the start date can reflect documented onward sale or fitment when agreed.
