Hi guys
Had my a4 272 for 3 years now and had a tdi tuning box on for most that time.
I recently noticed when starting the car first thing in the morning the car started juddering violently and the revs were hunting.
The start stop fault came on and the car cut out.
It happened again just yesterday and I quickly reversed out of the drive before it cut out again and carried on my way and noticed nothing different about how the car drove.
I'm worrying about what it could be? I've done 56k miles and the last service was done at 41k
Done mostly motorway miles since and doing a service in a few weeks.
I'm thinking a possible injector fault as a recent diagnostic showed that my v6 wasn't firing properly.
Spoke to tdi who said this fault can be possible due to the box changing the fueling etc.
The only different thing I've done recently is flash my gearbox with the tmc software as the car recently did a software update and that overwrote the file.
It does say in the instructions that the cars revs may hunt whilst installing but my cars symptoms showed up a few weeks after the installation!
Either way my warranty will be up in August so need to act soon!
Any others experienced this issue?
