A Guide to the Starter on Your 2006-2013 BMW 550i
Don't get stranded by a bad starter; understand the symptoms, costs, and replacement options for your V8-powered BMW.
- Starter replacement on the 550i is very expensive due to 4-7 hours of labor; the part's location is extremely difficult to access.
- The most common symptom of failure is a single 'click' with no engine crank, especially when the engine is hot.
- The 2011-2013 models with the N63 engine are prone to starter failure from 'heat soak' due to its location in the engine's 'hot-V'.
- Due to the high labor cost, using a premium new starter from an OEM supplier like Bosch or Denso is strongly recommended to avoid a repeat repair.
Is Your BMW 550i Starter Failing?
A failing starter on the 550i often gives warning signs before it leaves you stranded. The most common symptom is a single, loud "click" when you press the start button, but the engine doesn't crank. 🎬 Watch: 5 common symptoms of a failing starter motor You might also notice the engine cranking over more slowly than usual. These problems can be intermittent at first, sometimes only happening when the engine is hot—a condition known as heat soak. In some cases, you might hear a grinding or high-pitched screeching noise during or after starting, which could mean the starter gear isn't disengaging correctly.
Heat is the Enemy of the 550i Starter
The 2006-2013 550i was built with two different V8 engines, and the starter location varies. On the later 2011-2013 models with the N63 twin-turbo engine, the starter is located in the valley between the cylinder banks, right under the hot turbochargers. This design exposes the starter to extreme heat, which is a primary cause of premature failure.
Choosing the Right Aftermarket Starter
Because replacing the starter is such a labor-intensive job, the part you choose matters. You don't want to pay for this repair twice. Here’s an honest look at the available brands.
- Premium Brands (Bosch, Denso): Bosch is the Original Equipment (OE) supplier for many BMW components, and their aftermarket starters are considered a top-tier choice for quality and reliability. Denso is another highly respected OEM supplier known for making durable and efficient starters. For a complex car like the 550i, choosing a premium brand is a smart investment to ensure longevity, especially given the high labor cost of installation.
- Mid-Grade Brands (Remy): Remy is a well-known brand that has been making starters and alternators for a long time. They offer a solid balance of quality and price, making them a good mid-range option if a premium brand isn't in the budget.
- Value Brands (BBB Industries): BBB Industries typically offers remanufactured or new value-oriented parts. While the lower price is attractive, it may come with a trade-off in longevity or performance compared to premium brands. This could be a risk on a job where the labor is the most expensive part of the bill.
How Much Does a BMW 550i Starter Replacement Cost?
Be prepared: replacing the starter on a 2006-2013 550i is an expensive job. The majority of the cost is labor. The starter is buried deep in the engine bay on both the earlier N62 engine 🎬 See this step-by-step starter replacement for the N62 engine and the later N63 engine, 🎬 Watch: How to replace the starter on N63 V8 engines requiring many hours of a mechanic's time. Shops typically quote between 4 and 7 hours for the job.
| Part or Service | Estimated Cost |
|---|---|
| New Aftermarket Starter | $121 - $385 |
| Shop Labor | $750 - $1,200+ |
| Total Professional Replacement | $871 - $1,585+ |
Pro Tip: While the mechanic is replacing the starter, especially on the N63 engine, ask them to inspect nearby components like coolant pipes and gaskets. The "hot V" location contains several parts that degrade from heat. Replacing them at the same time can save you from another expensive labor bill down the road.
Frequently Asked Questions (FAQ)
Is a clicking sound always a bad starter?
Not always, but it's the most likely cause. A single, loud click usually means the starter's solenoid is working, but the motor itself has failed. However, a weak or dead battery, or corroded battery cables, can also cause a clicking sound or prevent the car from starting. It's always best to check that your battery is fully charged and the terminals are clean before condemning the starter.
Can I replace the starter on my 550i myself?
This is not a beginner-friendly job. For both the N62 and N63 engines, accessing the starter is extremely difficult and requires removing many other components like engine mounts, exhaust pieces, or the intake manifold. The job requires special tools, a significant amount of time (4-7 hours for a pro), and a high level of mechanical skill. For most owners, this is a repair best left to a professional mechanic.
Are there any recalls on the 2006-2013 550i starter?
No. While BMW has issued recalls for starters on other models and years, searches of the NHTSA database did not show any active recalls or Technical Service Bulletins (TSBs) specifically for the starter motor on the 2006-2013 550i.
Should I buy a new or remanufactured starter?
For this specific repair, a high-quality new starter from a brand like Bosch or Denso is the safest choice. Because the labor cost is so high, you want the most reliable part possible to avoid a repeat failure. While a remanufactured part can save money, the quality can vary. If you choose a remanufactured starter, be sure it's from a reputable brand with a good warranty.
