Lancia Ypsilon 1.3 JTD (70HP) DFN [2004]
km: 161870
date: 21jan2022

Issue: Failed MOT test because of an airbag fault light (red). This was an intermittent issue, with
the red light sometimes auto-clearing itself, sometimes staying on.

copy/paste from FES/MES diagnosis:

Autoliv MY99 Airbag (2F-2P-2T-I)
ISO Code: AE 80 07 02 8C
Errors found: 
3C - Front crash sensor (left)
No help available
The reason for this fault is Open circuit
The current status of the fault is Intermittent
The error counter value is 169

The issue was resolved at the official dealership. They changed the pre-crash sensor part
number 46843258. The sensor is nicely placed in the front center, see pics.

Needless to say that you need to take all the necessary precautions if you want to change
this part yourself, meaning disconnecting the battery for 30 minutes before touching
any airbag related connections.

6 months and 2600 km later, I confirm that the airbag light shows no false positives any more!

I am taking this opportunity to list some part numbers in case you want to service
your car on your own.
