Front Lower Trailing Arm Left Right For Audi Q7 4M 2015-Present 4M04076930 4M04076940

Q1: Which vehicles does this fit? Audi Q7 (4M, 2015–present) per the supplier table. European catalog data also lists A8 / e-tron / Q8 (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 4M04076930 and Right 4M04076940 are side-specific and NOT interchangeable. Order by side.

Q3: What is this arm exactly? The front lower trailing arm / track control arm — position: Front Axle, Lower, Rear (catalog: "Front Axle Left, Lower, Rear"). Aluminium construction, with ball joint (catalog-verified), approx. 3.2 kg. No electrical damping — a plain mechanical suspension linkage.

Q4: What about the letter-suffix numbers 4M0407693C/D/E/F? They are the current same-arm variants of this family (catalog OE list): 4M0407693C, 4M0407693D, 4M0407693E, 4M0407693F, 4N0407693F (Audi/VW), plus Porsche 95840769300, PAB407693 and Bentley 4M0407693D/E. The right-side variants 4M0407694C/D/E/F are listed per market listings. Order by the exact OE number; confirm by VIN.

Q5: Is this the lower rear arm (not the lower front)? Yes — the position is Front Axle, Lower, Rear (the front-axle lower rear link; the front-axle lower front arm uses different OE numbers). Verify the position against the original unit by VIN.

Q6: 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.

Q7: 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.

Q8: 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.

Q9: 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.

Q10: 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.
