Hi everyone, I have a 16 plate Audi a6 avant 2l, had it for a year now. I drive in economy mode 90% of the time and have the start stop on. The start/stop is quite sensitive I find at times, but when I stopped at a roundabout today the whole engine cut out and when I took my foot off the break, the engine would normally turn on again and it didn’t. I have to put it in to park, parking break on, hazards on and press the start button 5 times for it to come on again. The car was making a turning over sound as if you put a key in the ignition and turn it as far as you can to the right and hold it there. Does anyone think fuel rail sensor or something different? I have turned off start/stop in the hope it will not do it again. thank you! also comes up with ‘start-stop system deactivated. Please restart engine manually’
