Disco 2 Indicator and central locking fault

Recommended Posts

Hi 

Over the weekend the indicators stopped working on my 01 plated Discovery 2, the indicator indicators on the dash still work as they should but I have nothing working on each corner?7

I have also have a regular fault with the central locking which bizarrely seems to be related to the weather, in dry spells the internal switch works fine but in wet weather it doesn't work.

Many thanks in advance

If you have sunroof's they are probably leaking down into the passenger compartment fusebox or the BCU  or both. Water ingress is a bad thing which is all too common in many vehicles,not just Landrovers...

Have a look around the footwells and above,normally its quite obvious,corroded parts and damp carpets are the norm...

Thanks for that can you explain what the BCU is?

I am thinking issues with a relay re the indicators are these just pull out out replace items?

 

Thanks again

BCU = body control unit, a very complex electronic unit behind the glovebox which is responsible for various functions including central locking and indicators ... though the interior fusebox(IDM) is suspect as well cos it's very common to be affected by water or moisture, i doubt it's a relay cos there is one for each side... you should find a known good one on ebay from a non-facelift D2 and rule it out cos it's almost plug and play, all you have to do is to disconnect the battery first then after the swap and battery reconnection turn ignition on II and let it there 5 minutes to syncronise itself with the BCU, if you are unlucky enough to be the BCU the problem becomes more complicated cos it needs complex programming with dedicated tester...  here's one https://www.ebay.co.uk/itm/Land-Rover-Discovery-2-TD5-V8-Interior-Fusebox-YQE000250/254150541492?fits=Car+Make%3ALand+Rover|Model%3ADiscovery&epid=652655038&hash=item3b2c8d80b4:g:K1EAAOSwkhxcfXXk
