Q1: Which vehicles does this fit? Audi Q7 (4M, 2015–present) per the supplier table. European catalog data also lists A6 / A7 / A8 / Q5 / Q8 / e-tron (Audi), Bentley Bentayga, Porsche Cayenne and VW Touareg (MLB Evo platform). Confirm the exact model and year by VIN.
Q2: Is the left/right side interchangeable? No — this is a mirror pair: Left 4M0407509B and Right 4M0407510B are side-specific and NOT interchangeable. Order by side.
Q3: What is this arm exactly? The front upper control arm / track control arm — position: Front Axle, Upper (catalog position fields: Upper · Left · Rear). Aluminium construction, with ball joint (catalog-verified), approx. 0.8 kg. No electrical damping — a plain mechanical suspension linkage.
Q4: What are the other family numbers? The left arm family per catalog: 4M0407509C, 4M0407509F, 4N0407509, 80A407509, 8B3407509A (Audi/VW), plus Porsche-side 958407509B/C, PAB407509/A/B and Bentley 4M0407509C. Order by the exact OE number; confirm by VIN.
Q5: Do I need to replace both sides at the same time? Same-axle pair replacement is strongly recommended; an old arm on the other side causes uneven geometry and tire wear.
Q6: What should I pay attention to during installation? Tighten all bolts to the workshop-manual torque specifications with the suspension under load; after installation perform a wheel alignment (camber/caster/toe) and check the ride height per workshop manual.
Q7: Warranty policy and shipping damage? 18-month warranty under normal use. For shipping damage, inspect within 48 hours of receipt and send photos/video — the seller arranges a replacement.
Q8: Service life and maintenance? Depends on road conditions and climate. Check the bush for cracks and the ball joint for play during routine service; replace the arm if bush wear, play or crash damage is found.
Q9: Are aftermarket alternatives available? The interchange list for these OE numbers is available on request. Order by the exact OE number and confirm the model/year and side by VIN.
