However removing the DPF to achieve better performance is imo a step too far, and Andrei (Neo) points out all the negatives in his thread why it's not a good thing to do. There are better ways of improving performance other than just a remap, and they don't include removing the DPF. Quote:
Under the new MOT regs, if a car has a DPF or other components fitted at the time of manufacture and there not present at the time of the test the car will fail the MOT. I believe the above is correct,I could of course misinterpreted the latest docs?

It is an expensive mod to do if your car has no DPF problem (£600 - £800) but I can't think on anything else that will increase performance in the same way for less money other than a remap which is usually part and parcel of the DPF removal anyway. A straight through exhaust will also involve DPF removal and will not give a massive increase or change the sound much so I guess the only option after a remap is to then start looking at the turbo system and replacing injectors which will cost a lot more than a downpipe. I'd be interested to hear what the other ways of improving performance are (I'm not being cheeky here, I really am keen to know) As far as I'm aware diesels only get tested on smoke/soot rather than emissions so the DPF could well cause a problem during MOT. I've heard of a few people sticking the DPF back in to get their car passed. |

I'd considered removing the DPF and discounted it for all the reasons Andrei so eloquently expressed in his post. Playing around with turbo's and injectors is a whole new ball game as far as I'm concerned, and if I wanted that much more power I'd be looking at a different car all together. http://www.e90post.com/forums/showpo...&postcount=112 http://www.e90post.com/forums/showpo...&postcount=131

That;s not a bad price and a reasonable spec too.
Might be worth putting in an offer. If you don't someone else will snap it up sharpish I imagine. Just check that it;s had all its services etc on schedule. |

I'm not clued up on the complete options list but off the top of my head:
Auto-dimming door mirrors USB (code 6FL, allows you to listen to music of a USB stick) There are others like DAB radio etc and you might want to check if the seats are full electric with memory (according to the ad only part-electric). I also imagine it doesn't have lumbar support in the seats too. Having said that, it has most of the important stuff...alternatively hold out for one that has the exact spec that you're after. |

A mapped 330d will PWn an S3. a mapped 330d is not far off the performance of a 335d, but with lower running costs and cheaper to buy intially!

Candy (son ) as well as testing the cars you need to ask yourself a few questions to find what's suitable. It's clear you want a premium brand car that's fast but you don't want to be spending most of your time in petrol stations so the big BMW diesels fit the bill. If you do mainly short journeys around town, like to modify your cars and don't want to sound like a taxi then the S3 would probably be a better car. It's fine for someone to come on and say they do 40mpg in theirs but for all you know they could be doing 100 miles a day all motorway at an average speed of 60mph. You have to live with the car everyday so buy something that fits your everyday but also gives the fun you want. |

I have however have this vid of a Standard 335i (On board camera) vs a Re-mapped 335d. And this one of a Re-mapped 335d vs 400HP 335i. 335i near lane, 335d far lane.
