Mercedes-AMG E63 W213 Reliability: When the M177 Lives in a Wagon
Common Failure Points & Costs
| Component | Failure Mileage | Symptom | Est. Cost (USD) | Risk Level |
|---|---|---|---|---|
| Oil Separator / CCV | 50k - 80k miles | Multiple simultaneous oil leaks, rear main seal, engine-out | $8,000 - $12,000 | Critical |
| 4MATIC+ AWD Transfer Case | 60k+ miles | Light shudder, fluid leak, 4WD warning | $1,500 - $3,000 | High |
| Air Suspension (If Fitted) | 5-8 Years | Corner sag, compressor noise, suspension fault | $2,500 - $5,000 (Full System) | High |
| Valve Cover Gaskets | 60k - 100k miles | Oil smell, residue under covers | $700 - $1,500 | Medium |
Reliability Verdict
The E63 W213 is arguably the greatest performance estate in production. The M177 engine reliability profile is identical to the C63 — the oil separator is the primary ownership risk. The E63 adds 4MATIC+ drivetrain complexity and optional air suspension, both of which can generate additional bills. The estate body means it is often used for family/estate duty — heavier loads, more suspension stress.
Mercedes-AMG E63 W213 Reliability: The Ultimate Practical Supercar
The Mercedes-AMG E63 W213 is a special kind of madness. It is an estate wagon — all the family practicality of a Volvo — with a 603 hp M177 twin-turbo V8, 4MATIC+ all-wheel drive, and a 0–60 time of 3.3 seconds.
It is also one of the most capable all-weather performance cars ever made.
Reliability-wise, the M177 engine tells the same story as in the C63. But the E63 adds AWD complexity and optional air suspension to the equation.
1. What Makes the E63 Different from the C63
| Factor | C63 W205 | E63 W213 |
|---|---|---|
| Engine | M177 469–503 hp | M177 571–603 hp |
| AWD | Rear-wheel drive | 4MATIC+ (switchable to RWD) |
| Body | Sedan or Coupe | Sedan or Estate (Wagon) |
| Suspension option | Fixed dampers | Optional AIRMATIC air suspension |
| Weight | ~3,900 lbs | ~4,400 lbs (estate) |
The E63 S Estate is the flagship — 603 hp, air suspension, all four seats usable, and a boot big enough for strollers. It is also heavier, which means brakes and tires work harder.
2. Engine: Same M177, Same Separator Risk
The E63 uses a higher-output tune of the M177. Same physical engine, same oil separator vulnerability, same valve cover and cooling risks. See the AMG M177 Engine Reliability Guide for the full technical breakdown.
Key data for E63 owners:
- Oil separator failure: $8,000–$12,000 engine-out service.
- Typical mileage: 55,000–80,000 miles.
- Detection: multiple simultaneous oil leaks from different locations.
3. 4MATIC+ AWD System
The E63’s defining drivetrain feature is 4MATIC+ — an electronically controlled all-wheel drive system that can send 100% of power to the rear for “Drift Mode.”
- Transfer case seals: As with all AWD systems, the PTU (power transfer unit) input and output seals leak over time, typically starting at 60,000+ miles.
- Cost: $1,500–$3,000 for seal replacement and fluid refresh.
- Prevention: Change transfer case fluid every 30,000 miles despite “lifetime” Mercedes recommendation.
4. Optional Air Suspension (AIRMATIC)
The E63 Estate is commonly specified with Mercedes’ AIRMATIC air suspension system.
- Failure mode: Air strut rubber bladders degrade over 5–8 years. Corner sag is the first sign.
- Compressor burnout: If one corner sags and the car keeps driving, the compressor runs continuously and burns out.
- Cost: $2,500–$5,000 for a full system refresh, depending on how many corners need replacement.
- Prevention: Do not ignore a sagging corner. Address immediately.
5. Year-by-Year W213 Reliability
| Year | Key Note | Rating |
|---|---|---|
| 2017 | First year; best avoided (early calibration) | Fair |
| 2018 | Software matured; best early value | Good |
| 2019 | Peak production; most Parts available | Good |
| 2020 | Mild refresh; same mechanicals | Good |
| 2021 | Excellent long-term choice | Very Good |
| 2022–23 | Low mileage used market; strong value | Very Good |
6. Annual Ownership Cost
| Item | Cost |
|---|---|
| Annual service (oil, filters, inspection) | $1,500 – $2,500 |
| Brakes (front axle, amortized) | $1,500 – $2,500 |
| Tires (set of 4, AMG sizing) | $1,800 – $2,800 |
| Transfer case fluid (every 30k) | $400 |
| Annual Total | $5,200 – $8,200 |
Plus oil separator reserve: $8,000–$12,000 (one-time, expected at ~60k miles).
7. The “Shoot-Out” Verdict: E63 vs M5
The E63 Estate vs BMW M5 Touring (F91) is the classic practical performance comparison.
| Factor | E63 Estate | M5 Touring |
|---|---|---|
| Engine failure risk | Oil Separator | Low (S63TU4) |
| AWD | 4MATIC+ (superior) | xDrive |
| Interior | Mercedes luxury | BMW sport |
| Annual running cost | Higher (separator) | Lower (TU4 improved) |
| Best for | Luxury, comfort | Driver focus |
8. Buying Checklist
- Oil separator: inspect valley for residue on any car over 55k miles.
- Air suspension: cycle between heights and listen for compressor noise.
- 4MATIC transfer case: check underside for PTU fluid seepage.
- Tires: check for even wear across all four corners.
- Service history: demand records showing sub-7,500-mile oil changes.

Expert Buying Advice
Check 4MATIC+ unit for fluid seepage. Verify air suspension corners all raise/lower evenly and compressor activates quietly. Apply same oil separator checks as C63 — inspect valley for oil residue on any car over 55k miles.
