P0017 on MINI
Crankshaft/Camshaft Position Correlation - Bank 1 Sensor B
P0017 on MINI vehicles indicates crankshaft/camshaft position correlation - bank 1 sensor b. Au7o has documented this code across 5 MINI models — most commonly on Cooper, Cooper S, GP. This code means the engine computer has detected that the crankshaft and the Bank 1 'B' camshaft (typically the exhaust camshaft) are out of their proper timing relationship with each other. The computer compares the crankshaft position signal to the camshaft position signal, and when they don't line up within the allowed window, it sets this correlation code. This usually points to mechanical timing being off, most often from a stretched or worn timing chain, a slipped or stuck variable valve timing phaser, or a tensioner problem. You may notice rough running, low power, rattling at startup, or a no-start, and it should be addressed promptly to avoid valve-to-piston contact on some engines. Typical repair costs on MINI range from $1,000 to $3,000, depending on the specific model and root cause.
Common Causes of P0017
- •Stretched or worn timing chain
- •Worn or failed timing chain tensioner or guides
- •Stuck or faulty variable valve timing (VVT) cam phaser
- •Faulty VVT oil control/solenoid valve
- •Low or dirty engine oil affecting phaser operation
- •Faulty camshaft or crankshaft position sensor
- •Timing chain jumped a tooth or incorrect timing after service
- •Damaged reluctor (tone) ring
P0017 on MINI by Model
MINI Cooper(1 issue)
- N12/N16 Timing Chain Tensioner Failure2007-2013
The R56 Cooper's N12 and N16 engines suffer from premature timing chain tensioner and guide rail failure. The plastic chain guides deteriorate, causing chain slack that leads to rough running, rattling on startup, and potential catastrophic engine damage if the chain jumps timing.
MINI Cooper S(1 issue)
- N14/N18 Turbo Engine Timing Chain Catastrophic Failure2007-2013
The R56 Cooper S N14 engine (2007-2010) is particularly notorious for timing chain tensioner failure, even more so than the naturally aspirated N12. The higher cylinder pressures from turbocharging accelerate chain stretch and guide rail wear. The revised N18 (2011-2013) improved but didn't fully resolve the issue.
MINI GP(1 issue)
- Timing Chain Stretch and Rattle (N18/B48 Engines)2013-2023
The timing chain on the N18 (GP2) and B48 (GP3) engines stretches over time, causing a characteristic rattle on cold start and eventually triggering timing-related fault codes. The N18 engine is more prone to this issue than the B48. The chain tensioner cannot compensate for excessive chain stretch, leading to retarded cam timing, rough running, and in severe cases, the chain can jump teeth causing valve-to-piston contact. The high-RPM nature of GP driving accelerates chain wear.
MINI Hardtop 4 Door(1 issue)
- B38/B48 Engine Timing Chain Stretch and Rattle2015-2019
The MINI Hardtop 4 Door uses BMW-developed B38 (3-cylinder) and B48 (4-cylinder) engines that can develop timing chain stretch, particularly on early production units. The chain stretches beyond the tensioner's compensation range, causing a rattle on cold start and eventually triggering cam position correlation faults. The B38 3-cylinder is more susceptible due to the higher vibration levels of a 3-cylinder engine. BMW/MINI has issued technical updates for the chain and tensioner.
MINI John Cooper Works(1 issue)
- N14 Timing Chain Tensioner Failure (Death Rattle)2008-2012
The N14 turbocharged engine in early MINI JCW models suffers from a defective timing chain tensioner that allows the chain to develop excessive slack. This produces a loud rattling noise on cold start (known as 'death rattle') that can progress to timing chain skip or breakage, causing catastrophic valve-to-piston contact. BMW settled a $30 million class-action lawsuit and extended timing system coverage to 7 years or 100,000 miles for affected 2007-2010 models. The N14 was replaced by the improved N18 engine starting in 2011.

What does P0017 mean on MINI?▼
P0017 stands for "Crankshaft/Camshaft Position Correlation - Bank 1 Sensor B." This code means the engine computer has detected that the crankshaft and the Bank 1 'B' camshaft (typically the exhaust camshaft) are out of their proper timing relationship with each other. The computer compares the crankshaft position signal to the camshaft position signal, and when they don't line up within the allowed window, it sets this correlation code. This usually points to mechanical timing being off, most often from a stretched or worn timing chain, a slipped or stuck variable valve timing phaser, or a tensioner problem. You may notice rough running, low power, rattling at startup, or a no-start, and it should be addressed promptly to avoid valve-to-piston contact on some engines. On MINI specifically, this code is documented across 5 models.
What causes P0017 on MINI vehicles?▼
Common causes on MINI: Stretched or worn timing chain, Worn or failed timing chain tensioner or guides, Stuck or faulty variable valve timing (VVT) cam phaser, Faulty VVT oil control/solenoid valve, Low or dirty engine oil affecting phaser operation.
