Peugeot 308sw t7 esp/asr fault

[Samuel308]

Hello, for about 2 years, yes, you read correctly, 2 years... What bothers me is the malfunctioning ESP or Semi-functional. It works until I pass a corner at a minimum speed of 60 km/h until then everything behaves fine and ESP works. Then when I turn off the car and start it again the error is gone and it repeats itself every time I drive. Lexia 3 shows error C1316. I don't know what to do next replaced gyroscope (also configured angle sensor, etc.) esp shows live values such as turning the steering wheel, position of the gas pedal, that's all in order, I just don't really know where to look anymore and everything I thought of didn't work. I did not find a single solution to this problem on the Internet. If necessary, I can also send photos of live values. Any answer will be helpful )

See the part I have highlighted in red - which seems to describe what is happening with your vehicle...

Fault Code:	C1316
Description of Fault:	Transverse acceleration sensor signal fault:Coherence. The signal from the gyrometer/accelerometer sensor is monitored by the ESP ECU every 100 milliseconds Possibility 1 Connector problem Possibility 2 Incorrect fitting of the gyrometer/accelerometer sensor Possibility 3 Absence or incoherence in the data coming from the gyrometer/accelerometer sensor Conditions of activation of the diagnostics: At moderate driving speed, drive round bends and roundabouts, without illumination of the indicator light nor operation of the ESP.
Conditions for Fault to clear:	The data supplied by the gyrometer/accelerometer sensor is valid
Downgrade Modes whilst Fault is active:	The ESP operation that is current goes its term. Once it is finished, cutting of all ESP operations The other sub-functions remain active. Switching on of the warning lamp and/or warning message: ESP/ASR indicator lamp
Symptoms:	Lighting of the ABS and ESP warning lamps
Suspect Areas:	Connectors Electrical harnesses Calibration of the gyrometer/accelerometer sensor Gyrometer/accelerometer sensor

Yes exactly like that! But do you have any problem solution? Adaptive xenon works.
No fault in xenon unit. If you need i will give you a vin number

[GiveMeABreak]

Nothing to do with the Xenons, but it is not happy with the data being received from the accelerometer sensor. When you changed it was the part exactly correct for this vehicle and was it new or used? Do you recall the part number for the sensor you replaced?

VIN would be useful. Post it here - it will be masked except for staff.

[Samuel308]

I replaced the gyroscope with the same part number only different date of manufacture,it was used from
308sw 2009 (same as my car).By gyroscope i mean the box with is in the middle of the car.

VIN: VF3**************[VIN obfuscated, can be read by forum staff]

[Samuel308]

Photo above is the gyroscope i installed this one is from my car.(old)

[GiveMeABreak]

A couple of points:

1) The sensor must be fitted the correct way around with the connector of the sensor facing the rear of the vehicle.
2) Any sensor that has has suffered an impact must be replaced.
3) When refitted, battery must of first been disconnected following the BSI Reset / Battery Disconnect / Reconnect Procedure, the fault codes must be cleared.

So you are unlikely to know the condition or situation of a used second hand sensor and personally speaking, I would never use second hand sensors , but I know they are not cheap to replace.

[Samuel308]

Thank you,i will try to replace it for new one
Can you guve me original number of the sensor for my car ? Not the one on the sensor but buying number.

We can help if you need an original, genuine part number or part diagram, and can't already find the info you need on the Forum. For this service, we do ask for a membership upgrade for official parts data as we are in turn charged for this. It will cover you for future part number requests for up to 2 years, so excellent value.

If interested, links are below, then provide your vehicle's VIN in full, which will be masked automatically when you submit your post.

Oh okay and are you sure that it will help ? It costs around 300€…

[GiveMeABreak]

You can never be sure - unfortunately and there is no guarantee that a new module will fix the issue.

Codes are there to help troubleshoot and provide pointers and we can see from the suspects there are several possibilities:

• Connectors
• Electrical harnesses
• Calibration of the gyrometer/accelerometer sensor
• Gyrometer/accelerometer sensor

So it's a matter of checking the obvious things like the connections and testing these (including not to forget the connections at the ABS / ASP module itself in case the connections from the the accelerometer to the ESP UCU are faulty at the ESP ECU end).

Try all the practical checks first before replacing parts.

[Samuel308]

Okay i will start tomorrow i have some schemes of esp from 308 i will give you an update.

[Samuel308]

Hello! So few updates i tried to make a calibration BUT lexia wrote that the calibration is not possible.
Esp wiring in dashboard is good the sensor wiring is all right the connection under the steering wheel is all right too.Power for esp sensor is there.It remains to check the esp wiring at the psf unit.

[Samuel308]

Update the sensor was incorrectly fitted (turned around)

Sometimes the simplest of things...
