Hi all, I have recently purchased an old A4 b6 avant 2.5 tdi quattro 180bhp, I have one of those ODB2 adapters and the android app TORQUE, which reads out power put down etc, I plugged it in and went for a... steady drive... and the max I could get it to read out was 130BHP, I know I should probably take the read out with a pinch of salt but even still 50bhp off what it should be is quite alot... So, now I need to make a plan on how to recoupe said horses and I need your help of things to do/replace in order to get them! I have scanned for errors and there is none, also, the car has done 190k!! (full service history) So here is my proposed list to do/buy, please let me know if I have missed anything (which I'm sure I have): 1, EGR valve delete 2, Injectors (prob wont buy any replacements due to price!!) 3, Full service inc k&n panel 4, Gearbox oil 5, rear diff oil 6, engine/gearbox mounts? (Not sure about this but seen a thread about replacing something called the snub mount or something??) Anything else I have missed? Glow plugs are just for engine start I think so they wouldn't need replacing for bhp, Is the turbo something that may be waring out, or is that something thats either working or its not, no in-between? Any comments would be greatly appreciated,
