Hi All, I have just recently bought a 530d. Its a 2003 530d e39 with 114k on it. Car in question: I have already changed filters including crank case oil breather, I have Mobil 1 oil coming home today and will be changed tomorrow, I have sorted all sensors that were faulty, I have changed the Angel eyes to white LEDs, I am going to look at and if not done yet remove the swirl flaps. Anything else i need to do? I looked at decat-ing and EGR delete but these seem to have very mixed reviews. Decat seems to make a lot of cars fail their MOTs on emissions and if it is welded in then its not a quick swap over come MOT time. EGR delete is controversial in that some people say it doesnt help, its bad for the engine etc. Others say it helps the engine not to breath its own crap and it has improved economy and response, especially when cold. I dont know though. I am in 2 minds about those. Im not bothered about power, responsiveness or MPG (not because i dont care but because i am happy with how they are at the moment). My main concern is the cars health and reliability. Any thoughts on what i should do from here? Thanks, Kevin.
