A Deep Dive into the Starter for the 2011-2017 BMW 535i GT xDrive
Diagnose a no-start condition and learn how to choose the right replacement starter for your N55 engine.
- A 'click-no-start' is the most common symptom, but always check the battery and its main cable connection at the starter before condemning the starter itself.
- Due to the starter's location under the intake manifold, replacement is a labor-intensive and expensive job; professional installation is recommended.
- For long-term reliability, choose a new starter from an OEM supplier like Bosch or Valeo. The high labor cost makes it risky to use a cheaper, lower-quality part.
- This is the perfect time to address common N55 oil leaks from the valve cover or oil filter housing gasket, as the intake manifold will already be removed.
Symptoms of a Failing Starter
A starter motor rarely fails without warning. On the BMW 535i GT xDrive, the signs are usually clear. The most common symptom is a loud 'click' when you press the start button, but the engine doesn't crank. This means the starter's solenoid is engaging, but the motor itself isn't turning. You might also experience a slow, sluggish crank, where the engine sounds weak as it tries to turn over. Sometimes, the problem is intermittent, working one day but not the next. In some cases, you may hear a grinding noise if the starter gear fails to engage the flywheel correctly.

Before you spend hundreds on a new starter and labor, check the main power cable where it connects to the starter motor. On the N55 engine, it is very common for this cable's eyelet to corrode and break, mimicking the exact symptoms of a failed starter. 🎬 Watch: How to diagnose electrical issues before replacing the starter. A mechanic can inspect this connection, which is located under the intake manifold. A simple cable end repair could save you from a costly and unnecessary starter replacement.
Choosing the Right Aftermarket Starter
Because replacing the starter on this vehicle is very labor-intensive, choosing a high-quality part is critical to avoid doing the job twice. The starter is located underneath the intake manifold, requiring hours of work to access.
OEM vs. Aftermarket Quality
For many European vehicles, the term "aftermarket" doesn't automatically mean lower quality. Brands like Bosch and Valeo are the Original Equipment Manufacturers (OEM) for BMW. This means they made the original part that came with your car. Buying a new Bosch or Valeo starter from an aftermarket supplier often gets you the exact same part you'd buy from a BMW dealer, but without the dealership markup.
- Top Tier (OEM Supplier): Bosch and Valeo are the safest choices for your 535i GT xDrive. They manufactured the original parts, ensuring perfect fitment and reliable performance. Some newer Bosch parts are made by SEG Automotive, which purchased Bosch's starter division.
- Quality Aftermarket: Denso and Remy are reputable brands. Denso is a major OEM for Japanese cars and makes excellent starters. Remy has a long history in automotive electronics and is a solid choice.
- Value Tier: Brands like BBB Industries offer a more budget-friendly option, which are often remanufactured units. While they can provide good value, their long-term durability may not match that of an OEM-supplier part. Given the high labor cost for this repair, investing in a top-tier brand is highly recommended.
Pro Tip: Address Oil Leaks
The N55 engine is known for oil leaks from the valve cover gasket and oil filter housing gasket. If you have an active leak, oil can drip onto the starter and its wiring, causing it to fail prematurely. While the intake manifold is off for the starter replacement, it's the perfect time to inspect for and replace these gaskets to prevent future problems.

Frequently Asked Questions (FAQ)
Is there a recall on the starter for my 2011-2017 535i GT xDrive?
While BMW has issued recalls for starter-related fire risks on other models, there are no specific, widespread recalls for the 2011-2017 535i GT xDrive starter motor at this time.
How difficult is it to replace the starter myself?
This is an advanced DIY project (Difficulty: 5/5). It requires removing the entire engine intake manifold, along with numerous hoses, sensors, and electrical connectors to gain access. It is not recommended for beginners. Most owners should budget for professional installation.
Should I buy a new or remanufactured starter?
For this specific job, a new starter from an OEM supplier like Bosch or Valeo is the best investment. The labor cost is so high that you don't want to risk a premature failure from a lower-quality remanufactured part. A remanufactured unit from Bosch can be a good option, but a brand-new one offers the most peace of mind.
What else should I replace at the same time?
It is mandatory to replace the single-use aluminum starter bolts. The OEM part number for the bolt set is 12410392577. It is also highly recommended to replace the intake manifold gaskets while everything is apart to ensure a proper seal upon reassembly. 🎬 Watch: Step-by-step guide for removing the intake manifold and starter. If you have any oil leaks from the valve cover or oil filter housing, this is the ideal time to address them.
