Had my springs done with an alignmentlast last month. 30K Service scheduled for Tuesday. Can get a SUM cal as part of service only if "I have a complaint". I'm going to pay for it if I can't come up with a reason (see below).<p>What are some of the "issues" that I could complain about that would justify the calibration under warranty?<p>Also, re TME springs: Went on my first long drive, and they seem schizophenic. On smooth roadway, the car is markedly tighter and improved in any setting. But when the road is imperfect, I have to change the C4 setting to compensate for the type of irregularities: 'Advanced' is too hard if the road is pockmarked while 'comfort' was acceptable. When I hit a patch with undulations rather than pavement breaks in 'comfort', the car would float on the down and smoosh on itself at the bottom, springing back during the next up to float even more at the next top. On this type of road, "advanced" was better.<p>As a result, though, I was constantly swithching. Would have been fun if I had steering wheel mounted 4C buttons, but got irritating. Can only think what my wife would have done to me if she were driving <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/biggrin.gif" BORDER="0"> While she loves sports cars, she isn't the sort to charitably tolerate this type of extra effort to a task that is supposed to be "point and steer". And I can't blame her.<p>The question (finally): Might the SUM cal quiet this down? Could it be that the lowering of the suspension loads the shocks in a way that the suspension performs better once the system is calibrated?

The vehicle behaves very unsettled post springs and pre-SUM cal. Even if you have to pay for it, it's worth it.

Re: SUM calibration ? (R_Rated)

I agree, but when I had the TME springs installed I noticed a little bit of settling. So ideally, if I were to do this all again, I would drive the car for a month and then have the SUM recal'd. My car has been fine in ride since installing the springs and I have yet to have the SUM redone. I suppose as long as you have it done everything should be ok.<p>Kevin

Re: SUM calibration ? (KVB-R)

I did notice a significant "settling" over the first couple of weeks. Waiting for this to occur before doing the SUM cal couldn't hurt, though since it's done statically can't see how it wouid help. Unless there is some "learning" that happens while driving (as per some engine management systems....).<p>I am looking forward to the cal re: what it accomplishe will report back......

The best way to explain as I see it is:<p>1. Car has springs changed out<br>2. Car is lowered down to the ground from lift leaving some preload in the suspension.<br>3. SUM is reset,<br>4. Car is driven and the preload is gone and the A-arms level out.<br>5. Car is driven for a month and the springs "settle" a bit<p>The original SUM sees everything as before driven at a value of, lets say 0. So once the car is driven with a combined effect of 4 and 5, the SUM now reads -2. It's still close to the remapped SUM but it's just a little off because the car settled. I do not know if this slight settle will make any difference at all, but like I said, if I had to do it again I would let the car settle and then have the SUM remapped. <p>I may not be explpaining this the best way, but it's the best I know how.<p>Kevin

were your headlights pointed down after u put the springs? My dealer had to spend 2 hours playing with the censors and re calibrating the sum until they got the headlights to point properly

Because your dealer's an idiot.<br>Tell them to turn the LIGHTS ON as they were supposed to do <IMG NAME="icon" SRC="http://www.vortexmediagroup.com/images/banghead.gif" BORDER="0"> and this would not have happened in the first place

Re: (JRL)

I had a problem with my headlights shooting up when I hit the brakes. did a SUM recal and things were good for a while. Now a couple months later the headlight are going up again when I brake. I checked the rear level sensors, there is a little play (normal?). Brought it in for another recal and no luck.<br>DAn

Interested in their attitude re: warranty once they see the aftermarket addition. I'll just say I had the car aligned and want the cal, and hope they don't look close enough to see 'em. Doubt they are sophisticated enough to notice the lower stance, but I'll know soon enough........
