Dashboard messages

[SteveEdge]

Hi everyone. I have had a Renault Kadjar 2016 for about six months. Seem to be getting new dashboard warning messages every month. So far it’s showing the following messages in orange:
Check vehicle
Check tyre pressure sensors
Check parking sensors ( now not working)
Check hill start assist ( now not working)
Check stop start ( now not working)
Check anti pollution system
Have had a new battery fitted and three local garages have tried to fix the problem with no luck
Messages can all be cleared but they return within a day or so. Advice is take to a main dealer but concerned that the cost will get out of control.
Any advice please

With issues like this that have already been looked at by 3 garages I would advise you go down one of two routes.
1) As you suggest you could visit a main dealer and have a full diagnosis and a quote for remedial work they deem necessary. You could consider having that work done elsewhere to possibly reduce costs but you may not find a garage willing to take that on.
2) You can run through a number of possibles yourself meticulously checking the condition of every part of the car's systems mentioned in the warnings starting with all the fuses in car and engine bay, then all the loom connectors methodically working your way through the car.

If you find something suspect then repair or replace as necessary and then reset all the faults and see if they still return after a day or so.
This is obviously a very long winded approach and will take time to complete properly. There is no point in checking the odd thing here and there unless you are very lucky, methodical progress is the order of the day. Not easy by any means but cheap!!!
