Still as nimble as a SWB?

A silly question about the passenger seat movement control from the rear seat.
Does it have an interaction with the (airbag-related) seat occupancy sensor, or does it just rely on anyone sitting up front shouting "Oi"?
(I think I know the answer to that... )

Yeah I think you know the answer to that

An inauspicious day today. I was tracking down why VCDS won't talk to anything and discovered a fishpond in the electronics box. Did the usual and blasted all the water out, contact cleaner, and WD40, then refitted all the connectors. Now it won't start

The ECU has corrosion on several pins and although its rare for them to get damp inside, it appears to have a short on the K-line so stops everything else talking. Of course that also means it won't tell me why it won't start... sigh

When the car had the original comfort seats, I can testify that pushing the 'magic' button simply moved the front passenger seat. Hannah (my mate Sue's daughter) used to regularly scare her mum doing that. It also came in handy on one other occasion when transporting someone wearing one of those plastic boots (for a foot injury).

Hi,
The wiring for the the passenger seat movement control is only an adapter which is plugged in under the passenger seat between the engine for the seat adjustment and the switch of the passenger-seat.
Remove it and use it for your "new" passenger-seat.

If you dont remove the Adapter, the "old" passenger-seat will not work, if you connect it to a car wirhout the switch at the rear-seats.

Regards Stefan

Hi Stefan,

Thanks for this I had come to the same conclusion by looking at the wiring diagrams, however the original seats with the adapter are long gone. I have effectively made a new adapter cable to do the same job

Original seats are now with ainarssems and I think they were possibly going to be made into gaming chairs/seats if I remember correctly.

The ecu is dead

Found some corrosion in the ecu connectors and hoped it was this, but no



Opened the ecu to find water damage:



Not much better after cleaning. These still work, so probably aren't the root cause



Corrosion on the connector



Even after cleaning with IPA it is still completely dead. The LWB has a unique ecu and there are none for sale anywhere, nor are there any standard FL1 4.2 A8 ecus available in the UK, although there are some for unpleasant prices in Europe. Luckily Marcel managed to find an FL1 A8 ecu in Poland so we're working on acquiring that. The next struggle of course will be working out how to code the immobiliser, which apparently needs the pin code from the old one
