Peugeot 106 Engine Won't Start

That sounds frustrating! I had a similar problem with my 106, although it was a petrol version. Did you check the voltage of the battery? Also, can you hear the fuel pump working when you turn the key to the on position?

The battery voltage seems okay, around 12.5V. I can't really hear the fuel pump, but it's always been pretty quiet. Where exactly did you have the problem?

Okay, I remember now, my issue was similar in that the car wouldn't start and the engine light was on. It ended up being corroded battery cable connections causing a voltage drop the ECU didn't like. I'd advise taking it to a workshop to get it checked out properly though.

Thanks for the advice! It turned out you were right, the battery cable connections were the problem. Cleaned them up and it started right away. Cost me 155€ for the work, but it's running fine now.
