    2004 Touareg issues x2 , ABS lights ect

    hello, just did an auto scan on a customers Touareg today, i must look at it properly during the week, just in case someone here had simular issues they may be able to steer me in the right direction..

    1) intermittant ABS warning light coming on, speedo stops working ect, do ignition cycle all ok again, happens every few days but not every drive, he says just in wet weather but not sure how true it is.. ill post Autoscan below but wondering would an intermittant power supply to ABS control unit cause faults for Databus in single wire mode faults? or would a faulty ABS control unit cause faults for power supply? or should i be looking at Gateway or CAN wiring??

    2) Whine noise from rear, i gave it quick drive, wasnt sure if its the prop shaft or the rear Diff, are diffs common for going faulty? because i thought props cause a vibration? i have no vibration but bad whine from 50 mhp upwards.. and if so can they be rebuilt??

    thanks..

    Front diff problems are more common. What about a bad wheel bearing?

    are they more common? noise is definetly middle or rear, sounds more rear of the car..

    slight noise from front RH front wheel bearing but not bad, no play in it, if there going don't they log mechanical malfunction faults? and G85 wont caliberate after dead battery? cause iv none of those symptoms

    Use WD. Check CAN wiring. I'd suggest to start at area under floor covering right side, from A pillar to B pillar (under front passenger seat).

    Location of corroded wires and affected circuits may vary, but in general yes, like in pictures in post #27.
    I have seen/repaired some amount of those

    Just an update guys , pulled up the carpet front passenger side and stripped off the main loom covering , located the 3 splice joints , there horribly coroaded, I redid the connections and put interior back .. Carpet was soaking wet so I cleared A/C drain pipes and the wiper panel drain too hoping it won't take in any more water again.. Problem was intermittent so I'll drive for few days see how she goes but I'd say it's fine now! I'll post pics after
