I had this 2004 '53 A4 PD130 Sport for 2 years, you'd think I'd know it took bloody diesel.... Fuel light on, 2 miles from home, stopped at garage 1 mile from home. Decided to 'treat' the old girl to some advance diesel, only with my mind on another planet I put advance unleaded in instead. Drove 1/4 mile and car stopped, funny thing is, I immediately twigged what I'd done! Got a tow the my local garage only just down the road - no-one left there now, but I've got to go and explain what an idiot I am in the morning. I'm hoping this will be a drain, flush, new filter, fill it up with DIESEL and that's all... what's the odds of injector, fuel pump etc damage?
