Had the car scanned as the esp light was on and its come back as the brake pressure sensor. Looking into this it seems quite common on certain years, also looks stupidly expensive!!! Anyone else had it go? Did Audi fix it for free or at discount? Read a few people get it cheaper and a few people with golfs and Leon's with same engine get it done for free. Lastly worst case they don't, there's a repair kit on eBay that says it attaches to the unit to fix the problem. Anyone used this?
