Dealer Spark Plugs change. Did they mess up the Camshaft Position Sensor?
Hello people.
2010 E92 M3 DCT, 35,000miles. I took my car in for a service at the dealer: - spark plugsWhen I got the car back, I've got a Check engine light (CEL), I used the Carly app to read the code and it says - 2717 Camshaft Sensor outlet Bank 1. QUESTIONS - Is it a coincident? Bad luck. Thanks for all the help. ---------------------------------------------------------------- Reason for doubt, it's right next to the plugs.

Unless the plug came loose there’s no way for a spark plug change to damage a cam sensor. The outlet sensor is the one on the outsides and it’s exactly that a sensor that reads a signal not much of a way to unintentionally damage it and they do go bad so it’s not uncommon. The OEM ones aren’t expensive and take about 15min to replace

Your best bet is to take the cover off and see if you see any physical damage to the sensor. If you do, then you have proof to go back there with.
Otherwise it is probably unrelated and perhaps because the car sat for a while. |

But when I started the car, the light came on. I did my own scan and tried clearing without success. So I went back in and told them about it. I made sure the service advisor who looked after my car knew that I made a complaint. I wanted to find out a bit more (thanks to you guys) before I went back to challenge them, hopefully with evidence of some damage to the plug, sensor or the cable itself. Otherwise I will accept it just went bang because of age or left for too long (common fault?); or attempt to replace myself if I can get to it.

There's no reason you should pay what the dealer wants to do plug changes. It takes about 2 hours and is an easy DIY. Save your money and do it yourself and then spend the savings on some cool mods.
