Power steering malfunction

[Antonio2]

Hello all.

Just thought I would share a story with you which could be of interest Aygo owners. (probably Mk 1's only)

A young lady friend of mine, is the owner of a 2007 Puegeot 107, which is more or less a re-badged Aygo as you will probably know.

A little while ago when driving along in town, she lost power steering assistance, and the steering warning light on the dash illuminated.

She is quite young, and has never driven a car without power steering, so needless to say- it scared her a bit !!

Instead of letting a garage diagnose the problem, when arriving a boy friends house, he thought it would be a good idea to disconnect the Battery in order to reset the  warning light. 

This did indeed  reset the steering warning light, AND, the power steering assistance returned. All seemed good !

Believing that her friend's idea had saved her a large sum of money. She carried on using the car, thinking the problem was just a intermittent glitch.

All seemed well for a few days until the same fault occurred again - without warning - no power steering + steering warning light illuminated.

This time she took the car to a garage. Their diagnostic scanner flagged up a code "C1554 - power steering malfunction". The garage had experienced another 107 previously with the same fault. The problem was a faulty steering ECU. Apparently, the ECU is located above the pedals. Rather than pay a large sum of money for a new ECU, the garage sent the ECU to a test and repair specialist, who offered a life-time guarantee for the repair. 

The car has been fine ever since. Hope this may help if you experience the above.
