P0341 on a BMW: Causes, Fixes & Repair Cost

🟠 Moderate severity · drivable

You can usually keep driving a BMW with P0341, but the engine may idle rough or stall, so get it checked soon.

What P0341 means on a BMW

On a BMW, P0341 means the engine computer sees a camshaft position signal from bank 1 that is outside the expected range. The sensor works with the VANOS variable valve timing system to help time fuel injection and ignition. A bad sensor, oil in the connector, or a stretched timing chain can all make the reading drift.

Is P0341 common on BMWs?

P0341 is a fairly common fault on BMW six-cylinder engines like the N52 and N54 as the camshaft position sensors age. Oil leaking into the sensor connector is a known pattern on this brand, and higher-mileage cars can also have timing chain wear. The engine usually keeps running, but idle and performance can suffer.

Commonly reported on: 3 Series, 5 Series, X3, X5.

Symptoms

Check engine light on
Rough idle or hesitation
Hard starting or intermittent stalling
Reduced power in some cases

Common causes

most common: Faulty camshaft position sensor on bank 1
common: Oil contamination in the sensor or connector
common: Damaged or chafed wiring to the cam sensor
less common: Stretched timing chain or worn VANOS parts

How to fix it

Fix	DIY?	Typical cost
Inspect the cam sensor connector and wiring for oil or damage	Yes	$10–60
Replace the camshaft position sensor with an OEM unit	Yes	$100–250
Have the timing chain and VANOS checked if the code returns	Mechanic	$800–2000

Frequently asked questions

Can I drive my BMW with a P0341 code?

Usually yes for a short time, but the engine may idle rough or stall. Have the sensor checked soon to avoid getting stranded.

Is P0341 on a BMW usually a bad cam sensor?

Yes. The camshaft position sensors on BMW six-cylinder engines wear out over time and are the most common cause of this code, though oil in the connector also happens.

How much does it cost to fix P0341 on a BMW?

A cam sensor replacement typically runs $100 to $250 with parts and labor. If a stretched timing chain is the cause, the repair costs much more.
