Today I started getting payback from the ColourDIS in my yellow Storm.
For the first time since it was fitted, this morning I got the EML - maybe it didn't like the cold night. The EML has been up on occasions before: from previous code-reads by owners of VCDS it has always been the ASV, and has gone away on its own after a while. Today though the EML was accompanied by a lack of power.
Thanks to ColourDIS I was able to read the codes in the car and, on looking them up on the Ross-Tech wiki, sure enough the ASV was there but also this time the N75 turbo control valve, hence no turbo. What I really like though was that I could clear the codes, they didn't come back on starting back up, and a quick test drive confirmed it was back to normal. That's one to keep an eye on obviously, but it's good to have the ability to get out of that situation.
Next job for it will be to graph the output from my ABS sensors, to see if I can prove that the traction control is coming on around sharp right-hand bends (of which I seem to have quite a few on my regular routes) thanks to the offside front sensor losing contact with the marker in the hub. The same bends taken in the other direction produce not a murmur of discontent.
