    Hello people.

    Car: 2010 E92 M3 DCT, 35,000miles.

    I took my car in for a service at the dealer:

    - spark plugs
    - oil service
    - differential
    - brake fluid
    - statutory checks (UK MOT equiv. TüV)​

    When 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.)

    - Did they break something / not connect properly / nudged it when doing the spark
    plugs? (see below)

    - Or is it possible I haven't driven the car for 7 months and it's broken whilst parked up for so long?​

    :bow2:

    Thanks for all the help.

    ----------------------------------------------------------------

    Reason for doubt, it's right next to the plugs. (click for full size) :cool:

    After driving the car around for a bit longer and after numerous attempt in clearing the error with the Carly app. The check engine light would return instantly when I started the car up. I finally had some time to investigate (+ film the process).
    Here are the results! :openfire:



    CASE CLOSED

    No offence mate but I don’t think anyone else would take their car into a garage for a service then collect it with a new fault and not return to the garage for them to correct it. Instead you’ve made video about it? I don’t get that at all
    Glad you got it fixed though

    Hi,

    fair point but the reason it all started was with the checking engine light relating to the camshaft sensor. I picked up the car on a Friday, with the another on going issue (diff noise issue, plus some more); shows that if I took teh car in for an entire day, all they did was acknowledge an issue and have to book the car in for another time.

    I don't have time to waste like that. If I took the cover off and there was nothing obvious, then of course I would have gone back to them as it could be a faulty sensor or whatever other issue it might be. But to book an appointment, wait, take the car in (not to mention this is not my local dealer), it would have taken way too much time vs me plugging in a cable and call it a day - lesson learnt whether to trust them or not.

    That's the reason why.

    Just to give you an idea, I've been back 3 times now trying to sort out the diff issue and many emails back and forth. It just wasn't worth the hassle if it was just the cable unplugged to go back.

    As long as it’s fixed I guess that’s all that matters :beer:
