Why Buy a 2018 Mercedes Engine from Auto Power Source

Mercedes-Benz catalogues its engines by chassis Type code rather than a simple model name, which is exactly where most 2018 Mercedes engine purchases go wrong. Every unit here is donor-pulled, logged against its Type code and VIN digits, and stored in our climate-controlled warehouse until it sells. Each one clears the same six-step inspection — VIN-matching, ASE testing, noise & smoke verification, full visual inspection, multi-angle photography, and palletized shipping.

Our ASE-certified technicians compression-test every cylinder and run a leak-down evaluation before any 2018 Mercedes engine is cleared for sale. You pay a fraction of dealer-new pricing for identical Mercedes-Benz engineering, ship free on a heavy-duty pallet anywhere in the continental U.S., and get up to a 3-year warranty plus 30-day money-back. Not sure which Type code fits your 2018 Mercedes? Text your VIN and we will confirm.

Option Cost Reliability Warranty Fitment Match
Used OEM (this collection) $$$ Best Value High Up to 3 years VIN-matched
New OEM (dealer) $$$$$ 2-4× more High Manufacturer Exact
Aftermarket / Reman $$$$ Varies 6-12 mo May adapt

Tested used OEM hits the sweet spot — identical Mercedes-Benz engineering to new, at a fraction of the cost.

2018 Mercedes Engine Buying Guide

  1. Identify the chassis Type code first. 2018 Mercedes engines are catalogued as 205, 213, 222, 217, 166, 292, 218, 231, 172, 117 and 156 Type. The Type code — not the trim badge — is the primary fitment key.
  2. Read the 6th and 7th VIN digits. Mercedes separates C300 (4J/4K), C350e (4H), C63 (8G) and C63s (8H) on this digit pair. Same displacement, different engine.
  3. Match body style within the same Type. The 2018 E-Class splits 213 Type (sedan/wagon) from 238 Type (coupe/convertible); the GLE splits 166 Type SUV from 292 Type SUV coupe.
  4. Confirm RWD vs AWD (4MATIC). CLS550 RWD (VIN 7D) and AWD (VIN 9B), and C300 RWD/AWD, use different mounts and accessory routing.
  5. Always run the donor VIN if available. We provide it on request for any engine in our inventory so you can verify mileage and history before you commit.

Our ASE-certified technicians verify every one of these points against your VIN before any engine ships.

Our 6-Step Inspection & Shipping Process

Every 2018 Mercedes engine we ship has been through these six steps:

1. VIN-Matching
We match the donor VIN to your VIN to confirm engine code, emissions calibration, and drivetrain fit.
2. Tested & Verified
ASE-certified technicians compression-test every cylinder and run a leak-down evaluation on each engine.
3. Noise & Smoke Verification
Units are run to verify normal mechanical sound and clean operation — catches wear static tests miss.
4. Visual Inspection
Every accessible component is inspected: turbos, manifolds, valve covers, accessories, sensor harnesses.
5. Photograph & Catalog
Multi-angle photos sent to you BEFORE we ship, for your approval.
6. Palletize & Ship
Strapped on a heavy-duty wooden pallet, shipped via freight at no charge.
