P0562 on a BMW: Causes, Fixes & Repair Cost

🟠 Moderate severity · drivable

You can usually drive a BMW for a short time, but a weak battery can cause odd electrical behavior, so have the charging system checked soon.

What P0562 means on a BMW

On a BMW, P0562 means the engine computer sees system voltage below about 10 volts. BMWs draw steady power even when parked, and the battery management system watches voltage closely, so a weak battery is a common trigger. Newer BMWs also require a new battery to be registered with the computer so charging stays correct.

Is P0562 common on BMWs?

P0562 is common on 3 Series, 5 Series, X3, and X5 models with aging batteries, which often need replacement every four to six years, and failing to register a new battery can cause charging problems. Alternator failure is less common but shows up on higher-mileage cars.

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

Frequently asked questions

Can I drive my BMW with a P0562 code?

Yes, for a short time, as long as it starts. BMWs use a lot of power even when parked, so a weak battery can leave you stranded without warning.

Why does P0562 show up on BMWs?

Aging batteries are the most common cause. BMWs watch battery voltage closely, and a battery older than four to six years is usually the first thing to test.

Do I need to register a new battery on a BMW?

On most newer BMWs, yes. The new battery must be registered with the computer, or charging can be wrong and low-voltage codes can come back. A shop usually charges about $250–$500 for a registered replacement.
