C1 Speedometer and Oil Pressure Errors

My 2005 Citroen C1 diesel is acting up. Speedometer shows an error, and there's an error stored. The warning light is on in the speedometer, plus the oil pressure lamp. It has 104819 km. Could this be the oil level sensor?

I had a similar issue with my C1. Sounds like a faulty oil level sensor. Have you checked the sensor's cable and plug connection for any defects? That's often the culprit.

Thanks. I haven't checked the cable and plug connection yet. Is this a common problem, and is it easily accessible?

Yes, the cable and connector are known to cause issues. While you can inspect it yourself, given the symptoms, it's probably best to have a workshop take a look to confirm and repair it properly. It cost me around 95€ back then.

I appreciate the advice. I'll take it to a workshop for diagnosis. Thanks for confirming the oil level sensor and the approximate repair cost.
