I recently replaced the oil on my S/S CDTI 68, but the oil light stayed on, and now I’m getting code 89, indicating that a service is due. On top of that, the engine light has come on intermittently a couple of times. I’m looking for a way to reset all the lights and beeps, but I’ve been hesitant to buy from eBay, some tools are so overpriced, and others just don’t seem reliable. Ideally, I’m looking for a reset tool with a built-in calculator or an Android Bluetooth app to avoid the need for a laptop. Does anyonehave a good solution?
