Bmw M6 P273D Engine Trouble Code
What is Bmw M6 P273D?
With Bmw M6 P273D, you may drive for several weeks with a malfunctioning MAF sensor, but expect decreased fuel economy and eventual stalling. Shop replacement costs $240–$400 depending on vehicle. The labour is straightforward, with most cost from the part itself.
P273D on the Bmw M6
Many Bmw M6 drivers first encounter P273D as a result of worn ignition coil packs. The design of the Bmw engine bay can trap heat near these components, accelerating wear beyond the typical service interval.

How to Fix Bmw M6 P273D
Diagnostic Steps:
Poor running symptoms align with MAP sensor malfunction. In some cases, a faulty MAP sensor will not trigger a code. The issue may represent separate wiring concerns requiring individual diagnosis.
Repair Solution:
A/C pressure sensor monitors refrigerant pressure changes. DTC sets when pressure change falls outside calibration. Verify A/C system function, refrigerant charge, and electrical connections.
Technical Notes:
For P273D, verify VCT solenoid operation. Look for stuck or sticking valves caused by contamination. Consult vehicle-specific repair manual for proper component testing procedures.
Bmw M6 P273D Repair Cost
VVT actuator replacement on the Bmw M6 for P273D is a more significant investment: $400–$700 including the oil flush required before fitting the new actuator. Using the correct low-SAPS engine oil after the repair is critical to prevent premature re-failure.
P273D Description
P273D engine trouble code is related to System Malfunction.
Main Cause
The primary reason for P273D OBD-II Engine Trouble Code is: Fuel Rail Pressure Sensor Circuit Malfunction.
Common P273D Misdiagnosis on the Bmw M6
On Bmw M6 vehicles, the turbo boost solenoid and the MAP sensor feed into the same diagnostic path. P273D caused by a faulty boost solenoid is sometimes charged to the customer as a MAP sensor replacement, doubling unnecessary parts spend.
DIY Repair Guide: P273D on Bmw M6
Clearing P273D on your Bmw M6 with a basic OBD-II reader ($20–$40) is straightforward: plug the reader into the diagnostic port under the dashboard, read the stored code, and clear it. If it returns within one drive cycle, the underlying fault is still present and requires attention.
Preventing P273D on the Bmw M6
Transmission fluid degradation on the Bmw M6 directly affects solenoid operation. Replacing ATF at 40,000-mile intervals (rather than the often-quoted 'lifetime fill' recommendation) is the best insurance against shift-solenoid codes including P273D.
Frequently Asked Questions — Bmw M6 P273D
A: P273D is a standardised OBD-II code that can appear on any make and model. However, the specific components and circuits that trigger this code, and the repair procedures involved, vary significantly between vehicles. The information on this page is focused on the Bmw M6.
