I'm sure you will be okay since you've called Audi Assist as soon as you got the message (assuming you haven't done many miles and hard braking since).

Unfortunately the unit will need to be replaced. You maybe able to get a specialist to recondition it but I would guess that it won't be much cheaper than buying a replacement cluster. It's dead simple to replace (youtube is helpful), but be careful as the are many variations/different part numbers and there are different styles over the years. There is also the standard colour and there's a darker tinted colour, so make sure you get one that matches your current cluster

Ouch! You've had particular bad luck with your A4! Mine hasn't been too bad in terms of non-wear and tear repairs, but then again i don't do many miles (around 3k a year)!

I hear you! I'm also annoyed with Audi, because they are well aware of the issue with the part, yet make no effort sending out comms to the owners!

I concur with the other responses! That is horrendous service from Audi! What a rip-off! I purchased a genuine OEM part from Audi for around £90 and it took me less than 5 minutes to replace (no exaggeration)!

It's unlikely that it's something the garage did. It's a very common issue so the timing is just a coincidence. Please do not drive it until the the sensor is replaced (it's so easy to do).

I wouldn't have thought the engine management warning light is related to the brake sensor. Probably a coincidence. Definitely get a scan done

Just seen this thread! I had a similar issue on my A5 sportback. It's a motor/servo arm motor (can't remember the proper name). I believe there are 3 motors on the drivers side and the one that needs changing is the most difficult to get access to. You don't need to remove the whole dash as the Audi instructions say, you can remove the dash panel under the steering and the side below the centre console and get access. You need to remove one of the other motors to get access tot he one to be replaced. It's a tight fit but possible. There's a guide on youtube somewhere.

Doesn't the S-line have more exterior details? The S-Line has a slightly different bumper (i little more sportier), has side sill trims, the bottom of the rear bumper is slight different - more sportier), and the alloys are better.

I'm glad that the problem is resolved. If for whatever reason the ABS is 'bricked', there are companies that can repair it for a fraction of the cost (around £500 i think), so you don't have to replace the whole abs system for £3k+, but you will be without the use of the car while the abs part is sent to the company to recondition and replace the chip/ROM.

I'm not sure what what causes the part to fail, but the part was superceded with a new part number (part number ending in A). I'm not sure if this new part number is more reliable than the old. I ended up paying £90 for a genuine OEM part from Audi as my car was relatively new and didn't want to risk going for a £20 chinese copy, but i'm sure they are just a reliable. Audi should be ashamed of themselves on how they have dealt with this fault and has left a bitter taste in many owners mouths. I moved from a Peugeot 406 Coup to the Audi A5 Sportback, thinking that the quality will be a step up, and to be honest the Peugeot, despite it's age was very reliable!

I agree, it's really really bad from Audi and they should update the message on the dash to say 'Not to driver further and contact them'. They are also well aware of this faulty sensor because so many people have experienced this fault and contacted Audi. There really should be a class action case against them!

Hi mate, Here's a video: This one shows the passenger side which is much easier to repair as there's much better access to the control motors, so it's not much help. I'm trying to find the video for the drivers side replacement (for the V159 motor), but no luck finding it yet.

Unless you regularly get your car serviced at an Audi dealership, you'll unlikely get any 'goodwill' from them. If worst comes to worst, you can send the ABS module to a specialist who can repair/reset it for under £500. I think i've posted the link of a company that does this in this thread (go back a few pages). I can't vouch for them though as i've never had to use them.
