Makes petrols seem more reasonable when you factor this in with higher costs of diesel the possible fuel savings are now outweighed.
[/quote]We thought about a petrol but I didn't want to loose around 10mpg.

Yeah but when you factor in higher price of diesel, higher initial cost of vehicle and these such costs then there is no real difference

I think I averaged c24mpg when I had my X5 and I'm getting about 19 in the RS, a 4.2 V8.

Even the Porsche can easily do 37 on a motorway run for gods sake which I never got in the X5 and yet the Porsche will do 60 in less than 5 secs and top out at 175

I think people get too hung up on diesels being cheaper to run. These days that is just not true.

The only benefit I see of a diesel now is the different driving charactistic, ie wafting along on a wave of torque which can be more relaxing.

[/quote]You can't really compare the RS and Porsche with a 2.2 Ton X5 that has the aerodynamics of a brick, I was comparing the 3.0d with a 4.8I.
My brother in law had an Audi RS4 and that was bad on fuel, he now  has a diesel Porsche Panamera that does 50 on a motorway run.

How do you know when the car has gone into its regen mode.
Ie are there any signs when driving the car, [ i dont mean lights on the dash], does it react differently.  Etc Etc ..???
Ta...

On my X6 there is a 'hot smell' and when stationary the engine fans run at full speed even with the engine off in order to keep the high temp of the exhaust DPF from damaging anything.  On a good motorway run the system regents approx every 300 miles or so.  Short runs are DPF killers, but a run of about 40 miles with the revs kept higher should clear the soot.

The fans can run on for up to 15 mins.  The DPF will get up to several hundred degrees - hence the 'hot smell'.

--------------------------------------------------------------------

For those actively thinking about DPF removal:
*. Removal of the DPF is an offence under Section 61(a3) of the Vehicle Construction & Use Regulations and makes the vehicle illegal for road use. 
*. Anyone considering DPF removal also needs to inform their insurance company as the vehicle now has an illegal modification. 
*. You also need to inform VOSA and get a new type test done to reclassify the VED class the vehicle now sits in.
*. And you can't sell the car on for road use.  You must declare the DPF has been removed.

[/quote]Buy a BMW C110 scanner, best £40 you will ever spend.
Ask for one with V3.0 software as for some reason V3.2 has had some functions removed.

Is there a post-2008 version?

Fabulous,
Just ordered one....

I had wondered why my car occasionaly seemed to have a hot smell.... I thought it was just a bit of sprited driving i had been doing.....

[/quote]I would get a v3.0 and give it a go, works on my Dec 07 X5.
The updated v3.2 software does work on the later cars but as some people have found out you lose some of the functions when you load V3.2.

So I hope I get one....

Martin.
How do i know if ive got the V3.0 version.
Ive just recieved the scanner,, ive not yet plugged it in, but theres nothing in the package to tell me what version it is...

Diesel Particulate Filter (DPF) removal will be a MOT failure from February 2014 onwards.

New rules for MOT to test for diesel particulate filter

Tests for diesel cars and lorries are to be tightened up to ensure vehicles have a critical exhaust filter if one had originally been fitted as standard, Roads Minister Robert Goodwill has announced.

Garages and testing stations will be required to check for a diesel particulate filter (DPF) in the inspection of the exhaust system as part of the MOT test (or annual test for heavy vehicles) from February 2014.

The vehicle will automatically fail the MOT test if the filter had been fitted as standard but is found to be no longer present.

The filter works by trapping solid particulate matter from exhaust gases. This type of filter has been in use for more than 20 years and helps meet European emission standards, improving air quality and health standards.

Some firms offer services to remove the filter, claiming it will improve the economy. But it is an offence to drive a vehicle that has been modified this way, as it will no longer meet the emissions standards the car achieved when it was approved for sale in the UK.

Roads Minister Robert Goodwill said:
"I am very concerned that vehicles are being modified in a way that is clearly detrimental to people’s health and undoes the hard work car manufacturers have taken to improve emissions standards. It has become apparent the government had to intervene to clarify the position on particulate filter removal given the unacceptable negative impact on air quality."

"This change to the MOT tests makes it clear – if you have this filter removed from your car it will fail the test."

The filters need to be ‘regenerated’ regularly through burning the soot to gas at a very high temperature, leaving behind a residue. If not carried out properly, regeneration can lead to a build up of soot, which can affect performance. This has led to some diesel vehicle owners opting to remove the filter, which makes their car illegal for road use.

More information can be found via the 'Diesel particulate filters guidance note' https://www.gov.uk/government/public...-guidance-note
which will be updated to reflect the changes to the MOT test.
