Known Mercedes-Benz Sprinter faults
Every fault below is documented specifically for this model — researched and verified before it’s published.
The OM651 2.2 CDI uses a balance shaft module mounted low on the engine block whose integrated chain-and-gear assembly also drives the oil pump. The timing chain tensioner for this sub-chain is prone to losing hydraulic pressure at idle after high-mileage thermal cycling, and the plastic guide rails fracture. Once the drive chain skips or snaps the oil pump stops instantly, oil pressure drops to zero within seconds, and the crankshaft bearings, big-end bearings, and camshafts suffer catastrophic seizure damage before the driver can react to the warning lamp. The failure is exacerbated by infrequent oil changes, low-quality oil, and the high mechanical loading typical of loaded Sprinter van use. Mercedes-Benz acknowledged the defect and issued an extended warranty in some markets but not universally, and many NZ/AU owners discovered the fault well outside any support window.
Symptoms to notice
Oil pressure warning lamp illuminates suddenly at idle or low speed
Loud mechanical knock from lower engine immediately before failure
Engine cuts out with no warning while driving
Low oil pressure audible ticking that escalates rapidly
Complete engine seizure with no restart
What to check
Request full service history showing oil change intervals under 10,000 km. Pull the oil filler cap and listen for rattling at idle with engine warm. Check for any prior oil pressure codes with a Mercedes-compatible scanner. Ask specifically whether the balance shaft module has been replaced or upgraded. On high-mileage examples above 180,000 km treat replacement as mandatory pre-purchase work.
Where to look: Lower front of engine block, balance shaft module behind the front cover plate
Ask the seller
“Has the balance shaft module or oil pump drive chain ever been replaced?”
“Can you show me every oil service invoice — what oil grade and what change interval was used?”
“Has the vehicle ever shown an oil pressure warning light, even briefly?”
“Is there any history of engine noise described as ticking or rattling at idle?”
02Crankshaft position sensor failure — stalling and no-restart
MajorOccasionalElectrical $250–$800 to fix
VS30 Sprinters (OM654/OM651 era) have a documented pattern of crankshaft position sensor failures: the van stalls or cranks without starting, often intermittently when hot, before the sensor dies completely. The part is cheap but the failure strands the vehicle, and intermittent cases are frequently misdiagnosed.
Symptoms to notice
Intermittent stall while driving
Long cranking or no-start when hot, starts when cooled
No tacho signal while cranking
What to check
Take a long test drive including a hot restart after 10 minutes parked. Ask whether it has ever stalled or failed to start; check service records for a crank sensor replacement.
Where to look: Sensor on the engine block/bellhousing area reading the crankshaft
Ask the seller
“Has it ever stalled or refused to hot-start?”
“Has the crankshaft sensor been replaced?”

Like any used car, it depends on the specific example and its service history. Across the 17 documented faults for the Mercedes-Benz Sprinter, the recurring problem areas are engine, body & rust, and fluid leaks. A Mercedes-Benz Sprinter with a full service history and no signs of the issues listed on this page can be a sound buy but each one needs to be checked individually before you commit.
What are the most common problems with a used Mercedes-Benz Sprinter?
+
We've catalogued 17 known faults for the Mercedes-Benz Sprinter, covering engine, body & rust, and fluid leaks. Two are written out in full on this page. The rest — with the symptoms to notice, what to inspect, and typical repair costs for each — are free once you create an account.
How much do repairs cost on a Mercedes-Benz Sprinter?
+

Should I get a pre-purchase inspection on a Mercedes-Benz Sprinter?
+
Yes. A Mercedes-Benz Sprinter inspection focused on its known weak points is the single best way to avoid an expensive mistake. KickTyres gives you a guided, model-specific inspection plus a market valuation and negotiation figure for $17.90 far less than the cost of missing one of the faults on this page.
