It's nver been said you can't do on a standard car.....but once you remap it...the light will come on.

Ahh..... I diddnt know that - so WTF would anyone pay up to £196.90 for a DV that'll be useless if they remap the car ?!

Never mind, I'll go back to some of the other interesting stuff on their website.................

IIRC there wasnt a problem fitting an atmos valve to the 1.8t until you remapped the car then the extra boost caused problems...

DaveU ran one AFAIK... obviously not anymore mind

Ran an atmos DV for a couple of weeks on my LCR way before it was chipped...

...no CEL, but fuel economy down into the teens, VAG-COM showed boost leak faults amongst others, and after the first couple of hundred miles, soft limp mode every drive...

Had one of these on my old black vrs, never had a CEL come up because of it. :confused:

It's kinda explained fully here why it's *bad*
