Auto Imports diagnoses and repairs Mercedes E350 Balance Shaft Failure problems in Edmonton, including the specific symptoms and failure patterns associated with this vehicle.
If your vehicle has a warning light, leak, abnormal noise, rough running, overheating, reduced power or another concern, we recommend diagnosing the actual fault before replacing parts.
COMMON MERCEDES E350 BALANCE SHAFT FAILURE ISSUES
Common concerns for the Mercedes E350 Balance Shaft Failure include:
- The balance shaft sprocket teeth begin to strip and wear
- The camshaft timing becomes erratic — the engine runs roughly
- Engine fault codes are set — camshaft/crankshaft correlation codes P0016/P0017 or Mercedes-specific codes 1208/1210
- In advanced cases, the stripped sprocket can cause the timing chain to jump or break
- The repair requires complete engine removal — a 30+ hour job
- If your engine serial number is BELOW 272.xxx 30468993 — your vehicle is at risk
- If ABOVE that number — the factory-updated sprocket was installed
- 2006-2011 Mercedes E350 (W211/W212) — most commonly seen
- 2007-2011 Mercedes C350 (W204)
- 2006-2011 Mercedes ML350 (W164)
- 2009-2012 Mercedes GLK350 (X204)
These problems can become more common as mileage increases, but mileage alone does not prove a component has failed.

MERCEDES E350 BALANCE SHAFT FAILURE EDMONTON (M272 V6) FAQ
HOW DO I KNOW IF MY MERCEDES E350 HAS THE BALANCE SHAFT PROBLEM?
Check the engine serial number on the front of the left camshaft cover. If it is below 272.xxx 30468993, your engine has the defective sprocket and is at risk. Auto Imports can verify this during an inspection.
HOW MUCH DOES MERCEDES E350 BALANCE SHAFT REPAIR COST IN EDMONTON?
The balance shaft repair requires full engine removal — a 30+ hour job. At Auto Imports, this typically ranges from $5,000 to $10,000 depending on the extent of damage found during disassembly.
What happens if I ignore Mercedes balance shaft noise?
The balance shaft sprocket will continue to strip, eventually causing the camshaft timing to fail completely. This can result in catastrophic engine damage — potentially requiring engine replacement at a cost of $15,000 or more.
Does Mercedes cover the M272 balance shaft under warranty?
Mercedes issued a TSB and offered goodwill repairs on some vehicles. However, coverage was inconsistent and many owners paid out of pocket.
