	===Distronic Part Numbers - W220 after 2004-06-01===		===Distronic Part Numbers - W220 after 2004-06-01===

	~~To be completed~~.		Parts for Distronic after 2004-06-01 are a bit different. Main difference is radar unit witch is no longer two-box, instead is only radar and module in one. Wiring harness is also different, it just contains fuse holder, ground connection and CAN-H and CAN-L connection. Grill and switches inside car are the same as before.

			Parts that has been changed:

			Wiring harness - A2205405930

			Radar and module unit - A2205454232

	~~On later M~~-~~B models more and more~~ SCN ~~coding was~~ introduced ~~and you will require SCN Coding for~~ the ~~Distronics~~ to ~~work~~. ~~The datacard must be modified~~ in ~~M-B Stuttgart first~~, then ~~the required~~ SCN ~~codes installed with an Online SDS~~.		After 2004-06-01 SCN Coding has been introduced, which close the way to use only DAS. To change coding in your car you have to add code 219 to your data card, then perform online SCN coding by dealership or some independent workshops. Rest of modules such as Instrument Cluster, CGW, EZS have to be coded and it can be activated offline by DAS. If you have access to Star Diagnosis you can change variant coding in ECU by Vediamo. (I have tried Vediamo by myself and I changed it successfully).

	~~You may need~~ to ~~update some software too~~.

	~~'''Be warned''' on these later vehicles there is no option for~~ you to do it ~~offline and Dealers and Independent Workshops may be very reluctant to code the SCN~~.

			==Notes on Using – Distronic==
			DTR will '''NOT''' engage:
			* For up to two minutes after engine start-up (This is the initialization or self test phase.)
			* Vehicle speed < 25 Km/h or mph
			* With Parking Brake activated
			* With ESP manually switched OFF
			* If gear selector is NOT in position 'D'

			DTR may be controlled in the same manner as the Cruise Control or Speed Limiter.

			DTR will switch off automatically for the same reasons as Cruise Control.

			The Distance potentiometer on the Centre Console regulates the DTR "following interval", or distance to the lead vehicle, from 1 to 2 secs.

			DTR screen can be displayed in the instrument cluster while driving without engaging cruise control (the word DISTRONIC doesn’t appear).

			DTR audible warnings are active without cruise control engagement, unless switched off by driver using the DTR switch on the Centre Console.

			DTR will not apply the brakes to slow the vehicle while driver is using the accelerator to exceed the DTR speed setting.

			If DTR display shows “ ---“ instead of the current vehicle speed may be due to dirt, snow or ice build up on the radar sensor or road mist, heavy rain or fog which can reduce radar signals enough to cause difficulty in detecting vehicles ahead.
