Superb DCC increase height.

[xess]

So, is it possible to increase ground clearance by changing springs for skoda superb with dcc? What kind of manipulations should be done to dcc system through vdc? 

[numskull]

My thought would be a no. 

[Bap33]

Maybe installing Scout version springs could increase height, but not sure normal version share the same shock absorbers with scout version. Scout springs coupled with normal DCC shock absorbers could lead to a "bad wedding"... AFAIK, DCC system only tunes the shock absorbers displacement speed, it doesn't play on their length.

Yes, I am aware that DCC lacks the capability to modify height. That is the reason for my inquiry.

There's one way to find out...fit 15mm longer springs. There's likely to be far more sag in the shock absorbers when on standard ride height springs than 15mm.

 

However, perhaps start with the tyre size.

 

Changing 235/45R18 to 215/60R17 will increase the ride height by 10.55mm. Then changing the springs, will give a combined increase in ride height of over 25mm.

 

Outside diameter of tyres

215/60R16 664.4mm

215/55R17 668.3mm

235/45R18 668.7mm

235/40R19 670.6mm

215/60R17 689.8mm

Monroe sells its DCC rear shock absorber for both standard ride height and increased ride cars. So if Monroe DCC shock absorbers can cope with increased ride height springs, I expect Bilstein DCC shock absorbers would also be able to cope.

The only question that remains is whether the dcc will display any errors on the dashboard.

 

Thanks Carlston.

I'm no electronic/computer expert, but the DCC isn't human...so won't know that you've changed the springs.

 

Similarly, if a spring was to break (which they often do on the Superb MK3) I doubt any error messages would display.

 

Bear in mind that each DCC shock absorber can be used with a large range of springs, ie. it isn't one DCC shock absorbers always has to be used with the same spring.

On autodoc, aftermarket springs are only shown for the following OEM part numbers out of the above list of nine increased ride height rear springs, ie. weight range 6 (0YF) to weight range 9 (0YJ). This is normal, because weight range 1 (0YA) to weight range 5 (0YE) probably aren't used much.

If you have a Superb MK3 with front wheel drive perhaps try 3Q0511115AS or 3Q0511115AT, and if you have a Superb MK3 with four wheel drive perhaps try 3Q0511115BA or 3Q0511115BB.

U'll need to recalibrate the DCC if u increase or decrease the spring height.

 

This requires OBDEleven or VCDS, and all 4 wheels suspended in the air.

[MarkyG82]

What benefit do you get for recalibrating DCC? Pretty sure people in the past have commented that the system still works when lowered with no coding changes.

There is no requirement to do the DCC recalibration - it will continue to work with no issues.

However it is highly beneficial to do it, especially if u want the shocks dampening (compression & rebound) to work well with the springs.

It made a huge difference to me.

 

the "science" behind the DCC recalibration.....

 

"calibration is done with all four wheels off the ground, so the DCC module stores the fully extended value of the sensors.

The theory is then that once the car is back on the ground the DCC module stores a "center" value. 

From that point it's able to do its thing based on the position of the level sensors, the accelerometers and your selected mode."

Thank you very much for your helpful replies.

 

I have one last question. Can I use the same suspension with longer springs, or are there different struts for the longer springs?

Bilstein B4 23-238978 DampTronic front shock absorbers are used to replace all four OEM part numbers, as shown in the list below.

3Q0413031AK

3Q0413031BE

3Q0413032

3Q0413032A

https://www.autodoc.co.uk/bilstein/7949490#shock-absorber

 

These same Bilstein B4 230238978 DampTronic front shock absorbers are also used to replace both Kodiaq OEM part numbers. The Kodiaq is an increased ride height car, so there seems little doubt that these Bilstein DampTronic front shock absorbers could be used with increased ride height front springs on the Superb MK3.

The same applies to the Karoq. It's an increased ride height car and Bilstein B4 23-238978 DampTronic front shock absorbers can also be used to replace the Karoq's OEM part number.

With the DampTronic rear shock absorbers, the Monroe is listed for the standard ride height and increased ride height Superb MK3 but the Bilstein is only listed for the standard ride height Superb MK3.

So it's not such a clear picture with the rear DampTronic shock absorbers. For this reason, perhaps try fitting increased ride height springs first because as well as having a small doubt about rear DampTronic shock absorber compatibility they are easy to fit...perhaps about half of the labour involved compared to changing the front springs.

 

If there are problems with the compatibility of your current DampTronic rear shock absorbers and increased ride height rear springs, then Bilstein might be able to help with their Bilstein B4 20-279547 DampTronic rear shock absorbers that they sell for cars such as the VW Passat B8 Alltrack and Karoq (with multilink rear suspension).
