woodyrvf750 Posted August 11, 2014 Report Share Posted August 11, 2014 I thought I'd share this little issue that I've currently got with my 3L which showed itself recently and to see if anyone can help.First some recent (possibly relevant) mechanical history.N/S/F wheel bearing replaced by Audi Stratford January 2014 @ 103708 kmCambelt / Waterpump replaced & MOT by Audi Stratford July 2014 @ 111151 kmThe lupo hasn't been used much since the Cambelt / MOT as I've been using another car I bought early July. I thought I'd better take the lupo for a spin to charge up the battery and warm it all up but all did not go well.The gearbox immediately seemed confused, clutch slip between 2nd & 3rd and on slowing the downshifts felt poor with some feedback through the brake pedal (more on that later). I've never had a problem with my gearbox to date so I was a little surprised.I plugged in to my VCDS and found no gearbox or other faults. I did a basic setting on the gearbox expecting this to cure the problem.It did not. Exactly the same behaviour from the gearbox. Slipping in upshifts and some unpleasant noised whilst slowing down. It was hard to know whether these were coming from the gearbox or brake system. Then whilst driving slowly round the block the ABS light came on the gearbox was immediately fine again, behaving perfectly in both ECO and non-ECO mode.Great, no gearbox mechanical problem but an ABS problem. VCDS out again, showed a Left front sensor fault. Simple fix, bought new sensor from VW, fitted, problem NOT fixed. Gearbox is fine but ABS light comes on with following fault;00283 - ABS Wheel Speed Sensor; Front Left (G47) 04-10 - Mechanical Malfunction - Intermittent So, I'm thinking, if it's not the sensor, could it be the wheel hub/bearing that the sensor takes it's reading from? Lack of use? I got the hub/bearing from Germany but it was a good quality OEM spec part (exactly the same brand as supplied by VW a few years ago for the front right). Any suggestions welcome. The car is booked in with Audi Stratford on Thursday morning this week to see if they can diagnose anything else but if there is anything I can do to sort it out myself I'd welcome the advice. Thanks. Quote Link to comment Share on other sites More sharing options...
Dblock Posted August 13, 2014 Report Share Posted August 13, 2014 Not much help. But check in a2oc too. There is a few guys with 3ls that might be able to help. Quote Link to comment Share on other sites More sharing options...
woodyrvf750 Posted August 13, 2014 Author Report Share Posted August 13, 2014 All sorted. Audi Stratford incorrectly fitted the hub so ABS sensor was struggling to pick up signal. See photos of both sides, you should not be able to see the little silver clips!https://plus.google.com/photos/110791491420644998400/albums/6047131778846808657 Quote Link to comment Share on other sites More sharing options...
Kes Posted August 15, 2014 Report Share Posted August 15, 2014 (edited) That good news. Why do you use an Audi dealer? I would have thought them to be very expensive and clueless about your car. Edited August 15, 2014 by Kes Quote Link to comment Share on other sites More sharing options...
Dblock Posted August 16, 2014 Report Share Posted August 16, 2014 Audi did an a2 3l too and most parts are the same. Shame the dealer fitted the part wrong negating their usefulness IMO. At least it's fixed. Quote Link to comment Share on other sites More sharing options...
electricracer Posted August 21, 2014 Report Share Posted August 21, 2014 i would put money on the fact that not one of the current mechanics working at the main dealer have ever worked on an A2,(and definitely not a 3L !!) main dealers have a large turn over of staff and as a result all the staff trained on the older stuff will have left and gone somewhere else in the trade, usually the good independant garages, personally i wouldnt send an older car (4 years +) into a main dealers you will pay over the odds and possibly have someone working on your car who has never worked on one before. its your choice but as they didnt fit the parts properly that should ring alarm bells.
