    please correct me of im wrong but isnt the caravelle lower from new by 20mm ?
    im not sure
    i want it slightly lower but only by another 20mm or 30mm im undecided
    shall i fit my 19" wheels first or after the lowering to see what it sits like ?
    im going for eibach
    thanks in advance

    Imo, fit the wheels first and see how it looks.

    I'm going to be honest here, for the sake of only another 2omm, I don't think I would bother. You need to disturb quite a few suspension components even to change springs, especially on the front end so risk/reward has to be weighed up.

    I would suspect the Caravelle has quite a refined ride compared to a van/kombi, and I don't think you'd improve this by lowering. Just my 2 cents.

    I was thinking about lowering but I'm happy with the way the van looks as standard.

    I rember @Pauly posting regarding lowering the caravelle think it wasn't possible because of cruise control and dynamic suspension.

    ive got ACC but not Dynamic suspension

    Its a bit of a grey area at the moment, VW UK dealers are lowering vehicles with ACC & DCC fitted but i have been forwarded info from a third party quoted as coming direct from VW Germany and it states any vehicle fitted with ACC and/or DCC should not be lowered as the systems are factory calibrated to standard ride height and cannot be recalibrated afterwards to compensate for the altered ride height, heres the info i was sent

    Arrrr so if you have ACC fitted on a van and use it for work and load it up heavily so it goes very low the ACC wont work ?
    that sounds daft to me
    people put lots of weight in vans and they go like 50mm lower, vw might as well say
    ooooh dont load ur van up for work if you have ACC
    doesnt make sense

    I only have normal CC so am delighted that I can now lower my van until the exhaust scrapes the ground; yipeee!

    Hi Pauly, do you know exactly where this quote come from, as the following sentence is not something i would expect a manufacturer to use if they have safety concerns "my guess is lowering would reduce distance and make the lower distance settings available unreliable and potentially dangerous if the driver relies upon them"
    Where safety is concerned i'd expect the manufacturer to be doing a bit better than guessing :eek:

    The sensor has a range of 200m and beam angle of 12 degrees, lowering the van will have no effect on either parameter.

    Simple Pythagoras suggests it would affect it.

    But so too would chucking 1 ton in the back !

    Sounds bogus to me, just can't see how lowering 20/30 mm will change the calibration.

    And the bit on the LED headlights is just frankly rubbish, all the MFD does when RHD is clicked is lower the beam a tad, the angled kick up is still their just a lower. Nothing fancy whatsoever.

    But I suspect the minimum working range has been set to 200m - lowering will reduce that range. Probably not by much (I could work it out but TBH can't be bothered) but still by a significant amount.
    Say the sensor is 0.5m off the ground - reduce that to 0.46m and you've sliced 8% off that height so you've cut that range to 184m. Not a lot but 16m is still just over three whole vans.

    The text i posted is not direct from VW but has been rewritten (im Guessing) into an email
    It came from here in a round about way

    Im not confirming or denying just passing on what i have been told/found out

    I can confirm 100% that the LED headlights have four way motors in them and are capable of moving up/down and left/right

    I do agree the height makes a difference, simple maths really ! But the system has to cope with variable ride heights - even your cali will have various ride heights depending on how many folks and beer is on board, a standard panel van even more ! To suggest that lowering a van( within limits ) makes the system dangerous and out of calibration is just frankly ludicrous .

    If the system is so finely balanced that 20mm makes a difference they'd need an on board set of scales to weigh the passengers !

    The original post has a BS smell to it....

    It's only a suggestion with a bit of maths thrown in. I guess a lowered vans average height is lower - so it's get lower still if loaded.
    I don't know but there could be a reason and I'm just using my noggin to suggest one.

    Pythagorus theory would have no effect on the sensor, if a sensor can see 200m at 0 degrees then wether it is located at 1mm or 1metre from the ground, it still has an effective range of 200m, the road contours will determine how far the sensor can see within 200m

    For pythagorus to have any effect you would have to assume the either 1) sensor is located tilting towards the road, 2) that it only sees at a downward angle 3) a lowered van would be lowered more at the front than rear

    We've got a car with the same sensor, when fully loaded the car sits a comfortable amount closer to the road than unladen the ACC still works fine no matter how the car is loaded.

    As lowering springs will be stiffer than stock springs, i doubt a fully laden van fitted with either spring will be that much lower than each other.

    We have lowered our 204 Exec with ACC and DCC, on the VW Eibach springs to keep the warranty intact, and have absolutely no issues whatsoever. I also know of one other who has done this as well. The lowering springs were listed for the vehicle, at VW.

    How does Pythagoras come into play? If the sensor is move by x mm vertically at source, the beam will differ vertically by x mm anywhere along the 200m range, or am u missing the point? As LED's go, won't the beam just be lower, same with any vehicle that's lowered?
