Audi SQ5 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.
SQ5 8R RHD references
8R2 423 055 T; 8R2 423 055 R; 8R2 423 055 AC; 8R2 423 055 AJ; 8R2 423 055 AQ; 8R2 423 055 BC; 8R2 423 055 BE; 8R2 423 055 AF; 8R2 423 055 BJ.
SQ5 8R dynamic references
Published ATG references include ATGJ41021NW, ATGJ41021RB and ATGJ41022RB for the approximately 2.4-turn dynamic family. The VAG label and PR code remain decisive.
SQ5 FY RHD references
Later units use 80A2-series VAG references. Published ATG service references include ATGJ40711NW, ATGJ40711RB and ATGJ40712RB; confirm the complete 80A2 label and software.
Standard, Dynamic and Lock-to-Lock Differences
Supplier data lists some dynamic RHD Q5/SQ5 racks at about 2.4 turns. Other Audi guidance cites about 2.5 dynamic and 2.9 standard; measure and verify.
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 SQ5 Electric Steering Faults
Heavy or intermittent steering
Assistance may disappear, return after restarting, or become heavier in one direction.

Enquiries include C10AC07, C10ACF0, B200000, 03803 and steering-angle or end-stop faults. Diagnosis is required before condemning the rack.

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.
