    P0342 Camshaft position sender -G40-, Signal too low

    The BFS is a bit of an odd one, the VW parts system even gets it wrong, the BFS uses this sensor design for the G40



    Part number 06A 905 161 c and is available from dozens of aftermarket companies such as Bosch, Delphi, FAE, Febi, Hella, Marelli, Meyle, NGK, Valeo etc

    The plug going into it is VW part number 1J0 973 723 and you may need new terminals but you can only buy these easily pre fitted to a repair wire, 000 979 021 EA for the recommended Gold plated versions and you would need two as they are double ended. If you need the little bungs I THINK these are 3B0 972 742 C. You can buy the plugs, terminals and seals from specialist suppliers such as Wurth but you may struggle where you are.

Nimble technicians, surely you should hang your heads in shame. Your wit works mighty wonders, has landed men on the Moon, replaced brains by computers, and can smithy a "smart" bomb. It is a crying scandal that you cannot take the time or be bothered to build us, what sanity knows we need, an odorless and noiseless staid little electric brougham.

    Thanks Keithuk for the link.

    Crasher, i bought the connector off ebay and i have asked one of my brothers to pop into the dealers to get the repair wire. I have used the VW repair wires in the past when i was putting a Digifiz in my g60, but many thanks for the part number for the gold plated ones.
    The camshaft sensor i also got off ebay but bought 06b905163a as that looks the same as what is on the back of the head by the throttle body, where as the part number you listed appears to be for the sensor when it is mounted behind the cam pulley.

    After checking the wiring diagrams and my wires on the sensor it would appear that the wire no:1 grey/red and wire no:3 yellow have been wrongly put in each others places.

    I will update once the parts i have been purchasing get air freighted here and fitted etc.

    Once again many thanks i really appreciate you taking the time to help out.

    Your are quite right, I copied and pasted the wrong number off of ETKA, it lists both and does not differentiate, only in the workshop system does it say the BFS is different to the AVYD.

    Okay, finally an update.
    I managed to get all the parts from UK and started with repairing the camshaft sensor wiring that was incorrectly wired to the sensor. Once this was done i fitted the new camshaft sensor and connected it all back. This got rid of the engine management light after a obdeleven scan and clearing of the fault code.
    So only the traction light light was left illuminated and fault code 'unknown C0200 status active' on the scan. I then fitted a pigtail wire repair connector for the power steering pressure switch as the wires were broken at the connector and then also fitted a replacement alarm ultrasonic sensors disable switch as the original was broken. And this got rid of the traction control light. Happy days!!!

    So i was just left with the two rad fans cycling on and off on high speed when the aircon is on. I tested the fans manually and they both work on low speed aswell as on high speed, so i think it is the fan control module which i have purchased together with the aircon pressure switch and aircon ambient temperature sender. I am hoping these parts when they arrive will sort out the aircon?
    The fans come on as they should with normal driving and the aircon has not been switched on/ used since.

    So now unfortunately as of Monday a new problem. The beetle was taken for front and rear brake pads to be changed and a brake fluid change as the fluid looked like it was never changed. After the pads were changed and the calipers were bled no fluid is coming to the right rear caliper. There is no fluid coming from the abs pump to that caliper. The brake pedal is very spongey and goes down quite some way.
    Does this sound like the abs pump needs to be bled?
    I know that the two nipples were not bled on the master cylinder and the bleeding was done the old fashioned way of pumping the pedal whilst the nipples were opened. Also the bleeding started either on the rl or rr caliper and then fl and then fr i have subsequently seen online that as the car has mk60 abs it should have been fr,fl,rr,rl

    And ideas?

    Whilst waiting for the purchased parts from UK i connected the obdeleven diagnostic device and managed to run a brake output test which managed to the get the brake fluid to the rear right caliper. A welcome result,i then used my Motive pressure bleeder and and bled the brakes, master cylinder two nipples and clutch slave 2 times round. The pedal is still very slightly spongey but will leave it like that for now.
    Once the couriered part arrived here i fitted the fan control module and the fans now work as they are supposed to with the aircon. The replaced FCM was the original one and was water damaged inside. I did not bother changing the aircon pressure switch after the FCM sorted out the fans problem. Unfortunately the aircon ambient temperature sender that i also purchased appears to have disappeared from the parcel ( most likely when Seychelles Customs opened the parcel to inspect the contents) , but it seems that the one in the car is working properly.
    Hope this helps anyone who has similar issues with their beetle.
