E61 Camshaft Position Sensor no signal
Hi all,
E61 530d m57 2007 SE Camshaft Position Sensor no signal 3EC0 and 3EC1.
car won’t start and it’s gone through 3 sensors in a month. I know this isn’t right but anyone have any ideas what it could be. car drives for a journey after fitting a sensor. Once you turn the car off it doesn’t start again. Anyone experienced this or could help - only done 87000 so I wouldn’t suspect timing chain engine sounds as it should - Rpm reads right.
thanks in advance

I've never heard of BPT. Maybe time to try OEM or at least a recognized brand of sensor. There are SO many trash parts being pushed on the market that I don't trust anything from a vendor who hasn't had a good name for a long time, or from a vendor I don't know.
Is there any damage to the tip of the sensor when you pull it out after the car won't start?

If it's not OEM, you are taking a chance with an iffy part. BMWs can be picky. I just checked my OEM sellers, and they only sell genuine BMW or Hella for that part.

Thanks guys - what is the oem part I just begrudge spending a fortune for it to blow again and again - bearing in mind I’ve done the same brand sensor 3 times - when testing the ohms on the sensor reads 4ohms on the broken sensor reads 155ohms so when I plug it in again the car starts and then after a bit doesn’t work again - so I put the old sensor on start and then new sensor on it starts - start it up a couple more times and it goes again.

You're measuring ohms statically, which doesn't catch iffy things. OEM costs $30 more. Try OEM, and if that doesn't fix it, return it.
