Camshaft Sensor - Help on Understanding Diagnostics
I'm getting a persistent camshaft sensor and camshaft control error. Here's a pdf of the output from INPA - CLICKY. 1) It doesn't say which cam sensor it is, and at around £100 each I'd quite like to know before buying the wrong one ! 2) Is the camshaft control error a result of the dodgy sensor, or is there likely something wrong with the VANOS system solenoid as well ? I'm guessing the solenoid would be the first suspect. Thanks, Steve. |

Yes, Camshaft error could be from sensor, or timing chain could have jumped to uncorrect position.

Is it common for the chain to jump ?? The engine seems to run OK, but then I've not driven another to compare to.
If it's jumped, will it be obvious when I take the cam covers off ? |

Just replace all 2 camshaft sensors, there are not expensive thing. You can buy it and replace them diy, very easy to do it, only 2 minutes job.

No problems on quality, as I did this nearly 18 months ago, and still burbling along nicely. |

I'd read so many people having trouble with aftermarket sensors, I was assuming I'd need to go to the dealer. If the ECP ones are OK I'll splash out on a pair. £130 isn't too bad I guess. Beats £200 anyway.
OT - I bought the subframe bushes from that ebay listing, they're Febi, the same as G'n'S sell. I'm fitting them tomorrow. The guy that rents out the tool is only about 15 minutes' drive from me so that's pretty handy |

Ok, good luck with the bushes-hope the weather holds out for you. Is the company you are hiring the tool from some motorsport company? If so that was the same place I was going to borrow it from - £40 for the week I think... |

Mainly THIS THREAD where several people seemed to have had the same experience. There were some other threads too.

Weather looks fairly good for tomorrow. I'll swing by ECP on the way home and see if they've got the cam sensors in stock too. I'll probably get it all running nicely just in time for the gearbox to explode.... |

Anyway, back on topic, I bought two new sensors from ECP, they seem to have gone up, £68 + VAT each now. When I got around to removing the old ones it seems one has already been replaced. The driver's side - the one causing the error - is definitely the original, while the passenger side is a gen BMW one but looking much newer. I fitted both of the new ones anyway. I just have a spare now. So far no more errors, and although I might be imagining it, the car seems to run smoother and pull more cleanly. Time will tell on both fronts but for now I'm happy |

Another satisfied customer!
No you wont be imagining it, it WILL run smoother, as did mine immediately after I changed them, and still to this day. If a sensor is duff, it'll be sending a duff signal to the ECU which will either be struggling like feck to sort the mess out, or not at all. Which in turn will affect the driveability. Nice easy, relatively-cheap fix, giving a big 'bang for your buck' feeling! Seems your list is getting shorter by the week, keep it up! |
