Resurrecting...
Tried to turn down my EGR with VCDS, went into engine, put in the secure login, but channel 10 adaptation wasn't an option. Just occurred to me, maybe the engine needed to be running??
That was on a 60 plate mk2 CR170.
I then tried on our other leon out of interest, 15 plate mk3 1.4tdi ST, put in the secure login, and adaptation channel 10 was there, thing like idle speed were listed but nothing about the EGR. There were no clear channel numbers such as the required channel 3. Also the stored values for idle speed was 780 I think, which isn't the expected format according to the VCDS wiki...
Using genuine cable and most up to date VCDS.
Anyone turned their EGR down on an mk2 CR170 with vcds able to advise? Not fussed about the other leon, yet...
cheers
