renault grand scenic PROBLEMS

[paulhelliwell2]

hi all i have a 55 reg grand scenic automatic which keeps throwing various errors at me
electric steering
battery charging problem
lock parking brake
oil pressure censor faulty
gearbox faulty
now i know there all electrical and i have read somewhere that the fuse box under the bonnet is prone for water getting in
or is it just one ecu that is at fault any help would be appreciated

It also might be worth getting your battery checked, as an aging battery can cause a whole load of problems on such electrically complex cars.

battery is only 2 months old

Could be a current drain somewhere that has reduced the voltage.

[paulhelliwell2]

could it be the battery not having enough amps?
i think the one on it only has 50 and someone said it needs at least 60?
thank you for the reply

If battery was slightly under spec I don't think it would cause troubles.
Well under spec may do so though.
I would check the alternator is giving good charge with meter. If ok then look for fuse and bad earth connections. Wiring diagram would be handy. If no joy then it may help to put on a Clip diagnostic tool for possible pointers.
