Your aware that until the coolant has warmed up the ECU won't allow you to go into highest gear? You need to run it for 10-20 minutes before it will engage the highest gear.
The manuals are available to buy but not seen any online copies as I believe the rights owner is quite savvy at tracking down ...

Yes that is visually correct, they come in all sorts of prices, the actual sensors are common it seems so you can actually get even cheaper variations normally with a different plug that can be adapted! Be aware however it often requires the fixing bolt for the sensor to be drilled out as they get ...

The Lambda sensor can't be ruled out totally, the manual has a lot of ticks covering many different areas of the engine. Its often the problem with intermittent faults/symptoms because as soon as you start altering anything your never totally sure if its actually affected the problem or just the ...

Looking at the engine manual a lot of the unstable idle speed faults relate to the Idle Speed Control (ISC) system starting from the ECU on pin 2W which should be between 10volts and battery voltage.
Another possibility would be for the Throttle sensor to have an intermittent problem, either in the ...

Do we know which engine it is V6 or 2l?

It depends on the age, early machines had separate PCM and TCM in separate boxes, later versions moved to having them on one board in a single box.
I would imagine for an 02 vehicle it would all be in a the same box up under the passenger footwell.

Right just responded on FB but here are the connections to the ECU itself; the gearbox manual is still here on my website http://www.g8dhe.net/bongo_images/Gearbox/RC4AEL.pdf

Normally its just removing the plastic blanking plate from the position you want to fit it in.

From the video it sounds like the starter motor is working but very slowly! Likely a flat battery especially if the engine is very cold, you can see all the other dashboard lights fade out as the battery voltage falls.

It varies across the country its not really practical to advise on costs!
You can get weld in replacement arches from Bongospares they are the only ones that do a correctly stamped/moulded style otherwise there are some arches that can be modified/stretched.

LED's are not a good option as they emit a narrow cone of light rather than a broad width and can actually be more night sight damaging than the all round light from a filament lamp.

Yes, thinking about there listed here https://lushprojects.com/bongopartsmk2/ ... mgno=.html in the diagrams.

The lower wattage wire ended bulbs used to be available from CPC just make sure you move the coloured sleeve and base for the wires across to the new lamps https://cpc.farnell.com/c/electrical-li ... ed%2Bbulbs

Very likely, there are some minor variations over the years but I'm not aware that they alter the electrical connections at all. But its not something that has often been reported on!

Welcome aboard!

Before you commit you need to understand that a simple swivel seat doesn't work!!!! You also need to arrange for the seat to flip out away from the engine cover to allow turning the only seat designed for this is here https://www.newdawnconversions.co.uk/seating many of us have them ...
