Bmw 535I Gt Fuel Injection Throttle Bodys

Bmw 535I Gt Fuel injection throttle bodys

Starting at $243.95, AutoBuffy stocks 3 fuel injection throttle bodies from Standard Ignition, VEMO, and GPD. The throttle body is the valve that controls how much air enters your engine — when it fails or gets coated with carbon deposits, the engine can't meter airflow correctly, leading to rough idle, poor throttle response, and stalling that gets worse over time.

Signs your Bmw 535I Gt needs a new fuel injection throttle body

  • Rough or erratic idle that fluctuates up and down at a stop
  • Hesitation or stumbling when you press the accelerator from a standstill
  • Check Engine light on, often with codes related to throttle position or airflow (e.g. P0121–P0123, P2111–P2119)
  • Engine stalls unexpectedly, especially during low-speed maneuvers or cold starts
  • Reduced power or sluggish acceleration that cleaning alone no longer fixes
  • Poor fuel economy that appeared gradually alongside other drivability complaints

Which fuel injection throttle body should you buy for your Bmw 535I Gt?

The main decision is whether to buy OE-quality remanufactured, a new aftermarket unit, or a direct OEM replacement. Each option differs in how the throttle actuator and position sensor are handled — some include a pre-calibrated throttle position sensor, others require you to transfer or re-learn the original. Match the bore size and connector configuration exactly to your engine.

Remanufactured (OE core rebuilt)
Best for
Budget-conscious owners who want OE-matched fit and a tested unit
What you get
Original housing cleaned, throttle plate refinished, sensors tested and reset — lowest cost with reliable fitment
New Aftermarket
Best for
Owners wanting a fresh unit without paying OEM prices
What you get
Brand-new throttle body with new bore, plate, and integrated TPS — no core charge, no wear history
OEM / Dealer-Sourced
Best for
Owners under warranty, lease-return prep, or needing exact factory calibration
What you get
Exact factory part with full OEM tolerances — highest cost but zero fitment guesswork
High-Flow / Performance Throttle Body
Best for
Enthusiasts seeking improved throttle response with supporting engine mods
What you get
Larger bore diameter for increased airflow — requires ECU recalibration and is not emissions-legal on all vehicles

Replacing a fuel injection throttle body on a Bmw 535I Gt

Moderate⏱ 1–2 hoursSocket set and ratchetScrewdrivers (flathead and Phillips)Throttle body cleaner and lint-free ragsOBD-II scan tool (for relearn procedure on drive-by-wire systems)New gasket or O-ring (often included with part)

Disconnect the battery, remove the air intake duct and any connected vacuum lines or coolant hoses, then unbolt the throttle body from the intake manifold. Install the new unit with a fresh gasket, reconnect all lines and the electrical connector, and torque the mounting bolts evenly to manufacturer specification. After reassembly, perform the throttle body relearn procedure required for your Bmw 535I Gt before starting the engine.

Frequently asked questions

How much does it cost to replace fuel injection throttle bodies on a Bmw 535I Gt?
Parts alone start at $243.95 at AutoBuffy. A remanufactured unit typically costs less than a new OEM part. Add shop labor — usually one to two hours — and total replacement cost can range from a few hundred dollars to more depending on your Bmw 535I Gt's engine layout and whether a throttle body relearn procedure is needed.
Can I clean the throttle body instead of replacing it on my Bmw 535I Gt?
Cleaning with throttle body cleaner and a lint-free cloth removes carbon buildup and often restores idle quality if the throttle plate and bore are the only issue. However, if the throttle position sensor, actuator motor, or bore itself is worn or damaged, cleaning will not fix the problem and replacement is necessary.
Do I need to do a throttle body relearn after replacing it on my Bmw 535I Gt?
Yes, in most cases. Modern drive-by-wire throttle bodies require the ECU to relearn the throttle's minimum and maximum positions after installation. This is done through a specific ignition key cycle procedure or with a scan tool. Skipping this step often results in a rough idle or stalling immediately after the swap.
Will a bad throttle body cause my Bmw 535I Gt to fail emissions?
It can. A faulty throttle body disrupts the air-fuel ratio, which can cause the catalyst to run inefficiently and trigger a Check Engine light. Most emissions tests automatically fail any vehicle with an active diagnostic trouble code, so a defective throttle body should be replaced before scheduling an emissions inspection.
How long does a fuel injection throttle body last on a Bmw 535I Gt?
Throttle bodies are generally long-lived components, often lasting well beyond 100,000 miles with periodic cleaning. Premature failure is usually caused by oil contamination from a faulty PCV system, coolant leaks near the unit on coolant-heated designs, or internal actuator motor wear on drive-by-wire systems used in city stop-and-go driving.
Is a remanufactured throttle body as good as a new one for my Bmw 535I Gt?
A quality remanufactured throttle body from a reputable brand is a reliable option for most drivers. The housing, bore, and sensors are inspected, cleaned, and tested to OE specifications. The main advantage of a new unit is zero wear history, which matters if the original failed due to a known design weakness in your Bmw 535I Gt's engine.
