Step will not work

[preisdm]

If the step isn’t working you could try and reset. Turn off the main red isolation switch in the electrical cupboard, then locate the ‘magic’ blue connector located on the left hand side under the dashboard. Look up from the footwell. Unplug this and wait a minute. Plug back in, turn on red isolation switch and see if the steps working.

Thank you so much!! this fix worked just fine with the step malfunction and saved us a trip to the mechanics

Hello,

Thanks for all the advice on this thread -- we are having the same issue with the step. We tried the reset suggested above by @Mr T , but no luck. We’ve taken the van to VW who say the electrics to the step are fine, so it must be a mechanical issue. They have advised a replacement step, which, as we are well out of warranty, is an incredible expense. I am wondering if it would be possible to buy a new step and do the like for like step replacement ourselves as we are relatively handy. Has anyone undertaken this and could provide some advice? The only videos I can really find online tend to be people fixing something wrong with an existing step (i.e not installing a brand new one) or installing it from scratch, which leaves it hard to understand what would be involved in a swap / replacement.

Thanks!

The step is a relatively simple bit of kit. Whats are the symptoms. Can you hear it try and move or nothing at all. I take it that its stuck in the in position

Hi there, yeah it stuck in the in position. There’s no sound from it or sign of it trying to move. So we are thinking it’s unlikely to be just stuck from debris.

Its two motors, a limit switch and some mechanics. The J608 control unit under the left side (passenger) dash does the control and logic so if you've already tried the blue plug trick and your control panel is working find but the step isn’t responding to the panel then its probably not a logic/software issue and perhaps its a fuse which needs a bit of sleuth work. This is what I think the architecture is :- while the control logic is powered from the habitation side the actual motors are powered via the J608 relays which in turn are fed from heavy duty fuses on the starter battery and they are located under the left side seat

Fuse holder B (SB) — driver’s seat base:
• SB8 — 30A — J608, terminal 30
• SB42 — 30A — J608, terminal 30
• SB43 — 30A — J608, terminal 30
• SB49 — 30A — J608, terminal 30

Fuse holder D (SD) — same seat area:
• SD1 — 30A — J608 (second‑battery models)
• SD3 — 30A — J608 (second‑battery models)

Check all 6 of those, they may not all be present. If you find one blown its a good chance that is your culprit, the challenge then will be if just blows again because there is a fault in the step motor but at least you are a step (pardon the pun) further forward in root cause identification.

Just a final question before you go full Sherlock Holmes on the fuses - when you try send the step out via the control panel, does the step icon go blue and stay blue or just no change?
