    Electronic Handbrake Saga

    hey guys/gals..need your advice: Replaced the handbrake module a week ago and all was good up untill now. I get an intermittent parking brake light that comes up. The functioning of the electronic handbrake works normally ie activates and releases on pressing the button. I've also changed the button/switch. My OBD11 has given these faults: 1) Right Parking Brake Motor Voltage Supply 02433, 2) Control module right channel voltage supply 02435 3)Function Restriction implausible signal 03263. Called my Mechanic who suggests rear caliper as I've already replaced the module but wants to scan the car. Will a VCDS provide a more detail answer, or should I just purchase a new caliper and try it. Help pls

    Very unlikely to be your actual brake caliper assuming its functioning correctly mechanically. Its much more likely to be the electronic motor attached to the rear caliper which engages and disengages the handbrake.

    The motor's are not expensive, I purchased one for my Audi SQ5 about 18 months ago and it was about $100 https://www.rolan.com.au/trw-parking...w-sta1583.html

    Your car being a B6 Passat uses a different part number for the motor, and according to the TRW product catalogue it should be part # STA1498 for a B6 Passat. Best to double check and do your own research before buying anything though. https://aftermarket.zf.com/en/aftermarket-portal/our-catalog/search-by-vehicle/#/article/STA1498?languageID=4&brandID=14,22,32,35,68,126,16 1,294,8888&countryID=AUS

    Pardon our interruption...

    The other possible cause of your errors is some damaged wiring or a damaged plug - if you have run over some road debris it might have damaged something.

        FPV: Hi.

        Maybe before you start throwing money at more new parts for this car - read the Ross-Tech wki pages for error codes 02433 and 02435

        Please don't PM to ask questions about coding, or vehicle repairs. The better place to deal with these matters is in the forum proper. That way you get the benefit of the wider expertise of other forum members! Thank you.
