Mercedes-Benz E63 AMG W212 buying guide
The W212 E63 AMG launched in 2009 with the naturally aspirated 6.2 litre M156 V8, and from 2011 switched to the twin-turbo 5.5 litre M157. Both came as a saloon or estate, with 4Matic four-wheel drive offered after the 2013 facelift.
The versions
- 6.2 (2009 to 2013): M156 naturally aspirated V8, 520hp
- 5.5 biturbo (from 2011): M157 twin-turbo V8, 520hp, or 550hp with the Performance Package (limited-slip differential and uprated brakes)
- 2013 facelift: 550hp, or 577hp in the E63 S, with 4Matic four-wheel drive available
- Seven-speed AMG Speedshift MCT automatic
- Saloon and estate
What to check on a W212 E63
3 model-specific things to look at when you view one. They're a starting point, not the full inspection.
Head bolts and lifters on the 6.2
What to look for: On a 6.2 car, check the coolant level, watch for a low coolant warning, and feel for a misfire, especially from cold. Ask whether the head bolts and lifters have been replaced and look for the invoices.
Why it matters: Some early M156 engines had rusting head bolts with recessed Torx heads that could snap or loosen, letting coolant and oil mix. Lifters could also stop spinning or seize and damage the camshaft lobes, the intake side especially. Mercedes' revised bolts, head gaskets and lifters fix it, and frequent oil changes help the camshafts.
Cold-start rattle on the 5.5
What to look for: On a 5.5 biturbo, start the engine from fully cold, ideally after it has stood overnight, and listen at the front of the engine for a rattle in the first few seconds. Ask whether the timing chain tensioner modification has been done.
Why it matters: On cars with stop-start, the timing chain tensioners can run dry when oil drains down overnight, causing a cold-start rattle. The fix is a non-return valve fitted in an existing hole in the cylinder head to hold the oil in, and Mercedes offered goodwill contributions towards the work.
Airmatic rear sag
What to look for: Park on level ground and look along the side of the car to check the rear sits at the same height as the front. If you can, look again after it has stood for a while. A rear that has dropped is the thing to note.
Why it matters: A leak in the Airmatic air suspension can make the rear sag. Sometimes it's simply a hose that has come off rather than a punctured air spring, so it's worth a proper diagnosis before assuming the worst.
