In fact - with VAG COM channel 12 looks nothing like it does here. Mine has a stored value of 0. Measuring block 12 looks something like with the binary word, the time ins seconds, the voltage and the temperature.
IQ & ID & Timing are directly related air temp , fuel temp , water temp and altitude . The ECU has Fuel maps for variances in all .Brock_from_WI said:It's not really a time setting as much as a temperature setting. My understanding of this mod is what your telling the ECU is it is "x" number of degrees cooler then it thinks it is. So if it's really 32F (0C) outside the ECU might read it as 20F (-6C). Based on that temp it lengthens out both the pre-glow and post-glow for a given length of time.
I have been wondering if this effects the temp the car thinks it is outside once warm as well. So if its 100F does it think it's only 90F as well and not change the IQ as much?
Change out your coolant thermostat. I have done this for several customers this winter and to my own car just last evening. My car went from 8 miles to reach normal operating temperature to 3.5 miles.jhedrich said:Is there a setting that can make the coolant glow plugs heat longer too? My car takes forever to warm up, but my sisters car heats up in no time at all. Hers is a 2003 mine is a 2000.
What the temperature say?ChuckDubDub said:Mine is a 2000, New Beetle. So if I set a lower number in the adaptation field, like 32650, but the "time" units still read 0, could that be an affect of my engine not being quite cold enough?
This is the case even though I shut off and restarted the ignition/ECU.
Thanks,

Yes. The coolant has to be very cold to see a number other than zero in that field. If you set the adaptation at 32650, you will increase your glow time by about 5-7 seconds over what it would normally be at any given temperature. It will also decrease the threshold at which they start to glow. You just cannot see the results unless the coolant temp is low enough.ChuckDubDub said:Mine is a 2000, New Beetle.
