Thanks for the advice Aragorn30d, will think about the map, as you say, if there is no added stress then that is the best way to go, my worry is that if i were to get into an Accident, would my insurance company be able to tell that i'd re-mapped the car? Also, is there anyway to do this DPF delete without revealing the horrible turbo whistle sound?

Its possible, but very unlikely that the insurance company could find out that you remapped the car unless you tell them.

To find out would require expensive dealer or tuner tools to read out the contents of the cars ECU, and then compare that with a unmodified factory file. Levels of effort that just dont seem worthwhile.

Ofcourse you should probably tell them that you've done it as with any mod.

And as for the whistle, its not really evident inside the car at all. You hear it a bit outside at low loads and thats about it. Not really a huge issue tbh.

Definitely not gonna think about selling, i've only had the car for 3 months, wish i'd known about sound issues when i made the purchase, but i didn't unfortunately.. Plus i know it will never sound as good as a modded petrol, but of course there are ways to make it sound better than stock.

When you talking about the re-map for performance is torque, is that done because removing the DPF decreases performance?

I know you obviously have to get the map that stops the ECU from showing error codes and DPF light etc. - but is the performance and torque map needed? Or just an extra that people do seeing as they are already getting the car mapped? Been confused about this for a while!

If you're not sure, could someone else please Clarfiy the above question please!!

I wouldn't want to increase power and torque at this point as I want the car to last as long as possible and not mess with too much stuff, I'm just doing this for the extra powersound and a couple horses.

The DPF is a restriction in the exhaust system, if you remove this the car needs to be programmed to suit and prevent any fault lights, running issues, etc...

You can do this re-programming without remapping for more power & torque, although by the fact that you've removed the DPF it will be gain power & torque, but considering the costs are basically the same, you'd be mad not to get it remapped at the same time.

My 330d is running 291bhp & 602Nm, it's been remapped for a couple of years now, mileage is currently 112k miles and there are not negative side effects, it's lovely to drive, good of fuel and goes like stink!

Your 325d is the same basic 3.0 engine, but has been de-tuned, it can safely run a lot more power and will not dramatically shorten it's life or mess stuff up, as you put it, these are a very reliable engine.

Stop worrying...
