Right...
dropped the car off and with all your piss taking, its actually very clever what they do.
German cars are setup to be "greener" due to the laws in germany in regards to emissions, the UK laws are not as strict as germanys. The car is factory setup to reuse some of the exhaust emissions to 1. lower the emissions coming out the exhaust, and 2. to reuse in the engine as air to spark the combustion.
What they do is lower the range which is allowed within the BMW software to make allowances for different countries regulations. So in doing this, they let more clean new air into the engine which reduces the amount of fuel being used as its got more air to cause the spark, in doing so, increasing the MPG and getting a cleaner sounding engine due to not using dirty air.
Comments please.
Sounds like your NOx emissions will be going up. dropped the car off and with all your piss taking, its actually very clever what they do.

The law is the same whether the car is sold in Germany or the UK.

Aren't the emissions laws set by EU thus they should be the same for all countries within the EU?dropped the car off and with all your piss taking, its actually very clever what they do.

Happy to be corrected though!
Euro 4 is Euro 4 in all EU member countries from that I can tell.

My MoT will tell me that then
No it won't, they're only tested for smoke.Is that all they did? £100 to change a single parameter seems like taking the piss to be honest.
His explanation of how it works is all wrong for a compression ignition engine anyway.

Basically, i think what he's doing is a very clever way, do some googling, you might be surprised someone knows a bit more than you LOL, guessing that's why he's running his own garage and I'm not.
You may want to check some of my posting history and get back to me on the bit highlighted in bold^^^;-)
I bet they've also adjusted the MPG correction factor in the iDrive. You can adjust it up to 25%.

genius.Adjusting the MPG Calculation
tters.I have wondered for a while if a lot of marques change the mapping of their diesels come first service so that they drive better. An emissions test cycle beating map for when it is first shipped which is then removed at the first service? It makes sense in my head, having seen the lengths which manufacturers go to to get thier diesels through emissions legislation.

I think roughly translated that means the block off the EGR valve.......... Which means a remap to prevent the MIL on the dash illuminating, which means you need to tell your insurers about the change.......
(PS, if your diesel is "sparking" it's probably broken ;-)

Would blocking the egr not increase fuel consumption slightly? In addition the engine would taking longer to warm up.
