Genuine Audi Coil Spring Insulator 4K0-512-149-C.

Key Product Information
Additional Information
| SYMPTOMS | Symptoms associated with a failing suspension spring (4K0-512-149-C): clunking or rattling over bumps, a bouncy or floating ride, uneven or cupped tire wear, nose dive under braking, or a corner that sits visibly low. Symptoms vary by model year and option content, so confirm fitment before ordering. |
| TROUBLESHOOTING | Recommended diagnostic sequence for this suspension spring (4K0-512-149-C): bounce test each corner, then inspect bushings for cracking and separation and look for oil film on damper bodies, and on air suspension compare individual corner heights with live data before replacing hardware. A scan tool with Audi specific coverage will show considerably more than a generic code reader. |
| INSTALLATION | Changing out 4K0-512-149-C requires suspended components to be torqued at ride height rather than with the arm hanging, otherwise the bushing is preloaded and will fail early. Confirm correct operation and scan for stored faults before returning the vehicle to service. |
| MAINTENANCE | Preventive maintenance around 4K0-512-149-C is inspection based, checking bushings, boots, and ride height at each service and correcting alignment whenever a suspension component is disturbed. A short inspection at each service keeps small issues from becoming large ones. |
| GENERAL_NOTES | Key consideration for 4K0-512-149-C: sport, standard, and adaptive suspension packages use different part numbers, so confirm the PR code on the vehicle data label before ordering. Ordering by vehicle identification number is the most reliable way to confirm fitment. |
| REPLACEMENTS | Associated components for the 4K0-512-149-C repair: mounts, bump stops, dust boots, and stretch bolts are replaced along with the primary component, and an alignment is required afterward. Ordering the related hardware up front avoids a second trip once the assembly is open. |
