Hi all,

I have a 2009 Audi A3. Recently I had a couple of lights come on the dashboard warning - first is an issue with the brakes as well as the ESP light as well. A VAG-COM scan indicated that there was an "intermittent" electrical fault with the ABS system. The code can be cleared, but will come back at a random time later (does not come back immediately, but intemitternt).Took it to mechnics to check out, they noted was a fault within the ABS control unit. They had suggested replacing the whole unit, which was quite pricey!

I am now at a crossroad as to what to do next. I had been considering upgrading vehicles - so if I was to fix, I would probably not hold onto the car for much longer.

In my mind, option 1 is to fix the fault and then sell the car in a fully functional / no issue condition. This requires upfront repair cost which would reduce the amount I would receive net.
Option 2 is to sell the car as is. The issue here would be that a sale will require a recent WOF, and I am doubtful an ABS fault light would pass a WOF - so may need to revert to option 1 from a legality perspective.

Two question I would have is:
1) whether anyone has experience with this sort of ABS issue and what sort of price range they got for repairs. I understand there are refurbished options as alterantive to the original/new units that I had been quoted on. Is this worth exploring - and if so, who would do it?
2) Is option 2 even an option here, or is there an option to sell the car in current condition (i.e. below market value, factoring in the fault).

Keen to hear any ideas you may have. I do appreciate any assistance anyone can provide here!

Thanks!

Sometimes as simple as unplugging the large connector on ABS unit, spraying contact cleaner on terminals then reseating connector firmly can resolve this.  Not always though.

If it?s not covered under manufacturer recall then Anything Electronic in Nelson may be able to repair. They repaired the ABS controller on my 01 A4 last year or thereabouts. Can?t remember exact price but was well under a grand. They will want the fault code(s) to narrow down what they need to look at.

what is the part number from the sticker or markings that are able to be seen on the ABS module?
