Right I am crying out for a HUGE help now, I am loosing the plot and donât know what I can do next!! Sorry for the long storyâ¦â¦â¦but itâs either a coincidence or partly something to do with it.Problem started off with my car having the ESP light on and ABS, once I got round to plugging it in the computer I found out it was a rear drivers side ABS sensor. Got that changed (Not genuine Audi) lights went off and wala! 2-3 days after driving about they came back on, did a repeat of the computer and it came up with the rear passengers ABS sensor. So changed that sensor (Not genuine Audi). At this point I thought it was a bit random that both had gone in a close space of time. BUT the lights didnât go off this time! So computer on again!! And said it was the drivers ABS sensor AGAIN, so checked if there was any dirt and checked the bearing. Bearing was a bit rough and the ring on the back was a bit cracked soooooo I changed that (Not genuine Audi). Once I changed the bearing and went for a drive my dash turned into a Christmas treeâ¦â¦â¦â¦â¦.. ESP ABS Red steering wheel Hand brake Engine management (now and again) Slight loss of power and steering slightly heavier. Iâve been doing a lot of googling / reading and I canât put my finger on it. My mate is an Auto Electrician he has checked all the wiring to the ABS pump, checked all grounding and various tests. But with each test drive it gave him different fault codes each time i.e. front ABS sensors or rear, some valve in the ABS pump. A funny thing was that he couldnât get rid of the ESP light after clearing all the codes. So from there he was stumped and an ECU test was next or a gamble with Audi if they could find something different. The ECU has been sent away to be checked and said it working fine and on it way back. Audi had a look for 2hrs and couldnât find anything! Really scratching their heads, next step with them it to start stripping ££££££££ Donât know if this relates to whatâs going, my battery was going flat after a couple of days standing. Now and again struggles to start like the battery is dead and then when you try again starts up fine! The alternator does a funny ticking noise when its starts up, is that ok?I donât know what to do next now! Could it be the alternator? Could it be something to do with the bearing I changed or is it just a coincidence that all this triggered off after changing the bearing? Massssssssive thanks in advance to any help!
