What would you do? (E55 vs SL55)
P0106. I'm hoping it's just a loose vacuum hose and I don't have to replace the MAP sensor.

I love SL's. Have fun with yours.
I just got back from the exhaust shop. I should have taken pics of the mufflers on the rack because they aren't stock, but I can't tell what they are. The dealer said that AMG SMA009a2304912000 was stamped on the side of the exhaust. Could anyone help me figure out what mufflers I have?

Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance Problem
What does that mean?
The Powertrain Control Module (PCM) uses the Manifold Absolute Pressure Sensor (MAP) to monitor engine load. (NOTE: Some vehicles have a Barometric Pressure (BARO) sensor that is integral to the Mass Air Flow (MAF) sensor and do not have a MAP sensor. Other vehicles have a MAF/BARO and a redundant MAP sensor where the MAP sensor functions as a backup input in case of MAF failure.) The PCM supplies a 5 Volt reference signal to the MAP sensor. Usually the PCM also supplies a ground circuit to the MAP sensor as well. As the manifold pressure changes with load, the MAP sensor input informs the PCM. At idle the voltage should be 1 to 1.5 Volts and approximately 4.5 Volts at Wide Open Throttle (WOT). The PCM looks for any change in manifold pressure to be preceded by a change in engine load in the form of changes in throttle angle, engine speed, or Exhaust Gas Recirculation (EGR) flow. If the PCM doesn't see any of these factors change while detecting a rapid change in MAP value, it will set a P0106.
Potential Symptoms
The following could be symptomatic of a P0106:
- Engine runs rough
- Black smoke at tailpipe
- Engine will not idle
- Poor fuel economy
- Engine misses at speed
A P0106 could be caused by:
- Bad MAP sensor
- Water/dirt intrusion affecting MAP sensor connector
- Intermittent open in the reference, ground, or signal wire for the MAP sensor
- Intermittent short in the reference, ground, or signal wire for the MAP sensor
- Ground problem due to corrosion causing intermittent signal problem
- A break in the flexible air intake duct between the MAF and the intake manifold
- Bad PCM (do not assume the PCM is bad until you've exhausted all other possibilities)





















Really depends how loud you want it to be.








Those wheels are the first thing I would change TBH (personal preference) with either the Style IV AMG 2-piece splits (SL65 versions) or even the black lightweight ones they making for the new cars....

Happy miles!
