Further to this topic, as stated above the water drains overflowed on the wifes Vellfire and dripped inside after night of rain.
Went out this morning with the intention of assessing what needs to be done based on others input, well, once I realised exactly where the drain hole was it became apparent there is another option.
Firstly you will need a mig gun liner (the inner part that the welding wire actually runs through), I pulled one out of my old weld torch and stripped off the outer plastic coating.
These liners are are very flexible yet some force can be pushed along its length, ideal for sending down narrow pipes/tubes.
1. Open sun roof
2. remove plastic trim that is attached to the side of the glass frame hiding the mechanism by pulling it downwards.
3.from the drivers seat pass the torch liner over the metal parts as shown in 1st picture and guide into the hole (fiddly part)
4. feed in the liner in a see saw action, mine was 3mtre and took most of it, will pull out easily.
NB. protect the roof liner from dirt.
