Frequently Asked Questions
Why does the ABS light turn on in my Audi A4? ⌄
Most commonly a faulty wheel speed sensor or wiring. Scan for codes (e.g., C0035–C0050), check connectors for corrosion, and verify harness continuity.
How often should I replace spark plugs on the 2.0L TFSI? ⌄
Typically every 40k–60k miles depending on plug type and usage. Misfires (P0300–P0304), rough idle, or poor MPG are signs to replace sooner.
What’s a quick check for worn control arm bushings? ⌄
Listen for clunks over bumps, look for uneven tire wear, and check with a pry-bar for excess play at the bushing.
My parking brake won’t release. What should I check first? ⌄
Verify battery health, test the EPB switch, and scan for codes (e.g., C1001/C1113). Inspect rear caliper actuators/connectors for moisture or damage.
Why does the rear end feel bouncy on rough roads? ⌄
Likely weak/leaking rear shocks. Look for oil residue on the damper body. Replace in axle pairs and get an alignment if geometry was disturbed.
Do I need an alignment after suspension work? ⌄
Yes — any time you replace arms, bushings, springs, or tie-rod components. Correct alignment protects tires and restores straight-line stability.
