a few problems i need help with.....2004 c5 avant

[d3m0n]

Right, i dont really klnow where to start as i have a few big things bugging me with the car and a few smaller issues. id like peoples views on:

a) PRNDS flash - i know its a ECU replacement/fix but what is everyones opinion on this? Repair the existing one or replace with a brand new one (my local garage told me there is a large difference in cost) is there any reliability issues with a fixed one or not?

b) Occassional water drip from the lighting unit in the front? Usually after a bit of rain, and i dont have a sunroof so its not the gutters there? I pulled the unti out an it all looked ok no water damage? Could it be something to do with the washer pipes (i had a similar issue with my old escort)

c) Airbag light comes on if i have someone sitting in the middle seat in the back, this is intermittent, is it a sensor thing?

The water drip and the gearbox things are my biggest concerns. Ive got no dosh after just spending £700 getting the alternator pulley replaced after seizing up (long story).

1) I would source a 2nd hand one before replacing
2) do you have a leak at the top windscreen seal
3) AFAIK there are no airbag sensors or connectors in the rear seats, if there are then you may find they have a high resistance reading and just need cleaning (common problem with B5 drivers seat connector)
