Peugeot 208 (2013) 1.6l VTi automatic -FAULT CODES-

[Yafi]

Hi @ all

Got a Peugeot 208 2013er 1.6l VTi automatic (left side driver).
Vehicle registration number:
VF3**************[VIN obfuscated, can be read by forum staff]

The following errors come up:
A: U1F1B LIN FAULT21
B: U1F3E No communication with telematric ecu

Couldn't find anything by google. My autoelectrician doesn't know much about Peugeot cars.

Please advise

Thanks in advance
Best regards

There should be another couple of digits on the end of that fault code, so I can only provide the following:

Fault Code:	U1F10 08
Description of Fault:	_built-in systems interface not communicating on the intersystems CAN. No emission of data from the BSI on the Intersystem CAN network for at least 2s.
Conditions for Fault to clear:	Emission of data from the BSI on the Intersystem CAN network for at least 2s.
Downgrade Modes whilst Fault is active:	None, however the following warning lamps may appear: Warning lamp MIL ABS warning lamp ESP warning lamp Power steering warning lamp Warning lamp STOP
Symptoms:	Starting problem Lack of power Jerking/stalling Poor operation of the electric power steering Activation of the cruise control or speed limiter function impossible Deactivation of the cruise control or speed limiter function impossible Deactivation/cut-off of the cruise control or speed limiter function The vehicle does not reach, or exceeds, the speed setting Use of the programmable limits for the cruise control or speed limiter difficult or impossible Difficult or impossible to adjust the speed setting (in cruise control or in speed limiter) Unwanted activation of the cruise control or speed limiter function
Suspect Areas:	CAN High and CAN Low lines (Short circuit to positive ; Short circuit to earth ; Short-circuit between the 2 lines) Any ECU connected to the CAN Intersystems network

As for the Fault with the SMEG Unit:

Fault Code:	U1F3E 87
Description of Fault:	Fault: absence of communication with the telematic unit. Absence of communication with the telematic unit (For 2 seconds).
Conditions for Fault to clear:	Communication with the telematic unit (For 2 seconds)
Downgrade Modes whilst Fault is active:	-
Symptoms:	Impossible to start up the telematic unit Instantaneous consumption information is frozen The average consumption displays dashes Range stuck Resetting to zero of the information on the average consumption for journey 1 or 2 not working
Suspect Areas:	Configuration of the BSI Electrical supply of the telematic unit Earth of the telematic unit CAN network Electrical harness Data communication ECU

Thanks a lot.

I thought the code by the related to the Smeg unit, because I pulled the fuse.. it's switching off and on all the time. Before it switches off the display freezes.
What I can do to get it working? I tried the 'fuse trick many times but it never worked for me except ones. The unit was working for about 10min properly but after I switched the car off and after 15min on again, it just did the usual thing.. on and off the whole time. Very disturbing, so I pulled the fuse..
Any advice?

Thanks in advance
Best regards

The unit can switch off with excess heat - normally the unit will lower the volume output first, and then if it is still too hot, it will power off until it cools. The Head Unit is behind the fascia / central console and ther tends to not be a lot of room there for air to circulate and cool. However if it is switching off in cool temperature also, then you may have a faulty connection or problem with the CAN network or any of the reasons listed on the bottom of the table in my last post above.

Hi again. Unfortunately I couldn't solve the Smeg unit issue. I'm still trying to avoid the Peugeot dealer workshop, here in South Africa they don't know their own brand correctly..
However: is there any information where exactly the CAN network wires are situated in the vehicle?
There is many issues that may be related. I had my wires getting checked a few month ago, not sure if really all were checked but I hope so, even the fuse box, BSI and the fuse box on the driver side.. all good.
Those faults are permanent:
U1F1A LIN FAULT21
U1F1B LIN FAULT
U1F00 fault event not stored in the fault logs
B1140 front left fog lamp control fault
B1331 electric window authorisation output fault
U1F3E no communication with telematric ecu

[(B1418 seatbelt Status -* but that one is only because I leave the seatbelt plug in*-)]
Unfortunately there is no further digits for them.
Sometimes they can be deleted. My actual problem with these faults is actually that my engine light comes on. I don't understand why though

Please advise. Thanks in advance

Another question about the SERVICE light. With the normal procedure it's not going off, is it maybe related to those issues?
In the cluster I always get faults like
A: Engine repair needed (before it came because of a faulty oxygen sensor cable management, as of another topic I opened)
B: gearbox repair needed (doesn't give any sensor faults)

[Yafi]

Please if any thoughts on it?

B1331 can be ether:
B1331 11 (Electric windows authorisation fault: Short circuit to earth) or
B1331 15 (Electric windows authorisation fault: Short circuit to positive or open circuit)

B1418 00: Fault in the status of the seat belt fastening information for determining the presence of the driver.
U1F00 00: Fault event not stored in the faults log.

Fault Code:	U1F1B 08
Description of Fault:	LIN2 fault. The BSI detects a short-circuit to positive or a short-circuit to earth on the LIN2 network wire.
Conditions for Fault to clear:	Absence of electrical faults.
Downgrade Modes whilst Fault is active:	Change to energy economy mode 5 minutes after cutting of the engine. Switching on of the warning lamp and/or warning message: Possibility 1 "Economy Mode Active" message Possibility 2 Flashing of the battery warning lamp for 7 seconds
Symptoms:	Multiple customer complaints.
Suspect Areas:	Network LIN2 Battery charge status unit (*) Fuel additive pump (*) Built-in systems interface (*) According to equipment
