L322 indicator madness

mfseba · Jan 1, 2019

Hello to everyone, I’m basically new to the world of the RRs, got a 2005 L322 couple of months ago. Sometimes it was acting strange (air suspiension, abs fault, battery draining), but somehow always came back to normal. However, in the past few weeks a new phenomenon occured:
The indicators have gone mad! If I turn it on the right side, nothing happens, but when I turn it on the left side, it starts to blink on the right... so basically I cannot use my left side indicators. Any idea from anyone where should I start to figuring out the problem? (I dont want to take it to a repair shop until there is no other option, avoiding to being ripped off.) thank you in advance!

In addition: when using the hazard signal, all lights are working properly, both sides.

Try making only right turns ?

Joking aside. have you checked the battery and alternator. a weak battery will throw up all kinds of electrical faults, I presume that Hungary isn't exactly balmy warm right now

Too cold for hand signals then.

Dont know if it helps but my old Clio did something similar and it was the hazard switch faulty.

As above, check battery is tip top and I mean tip fecking top.....

Also check the LCM for dampness - this is tucked up the side of the drivers side (UK) dash.

I would unplug sat nav unit sounds mad but damp in rear quarter effects my indicators etc

I can only surmise (as the indicators are powered from the LCM which is tucked up the side of the dash) that there is an earth problem....the indicators (rear) are earthed in the same rear corner as the nav drive (IIRC) so if that corner is damp - things may happen!

Thank you for the answers, I will try to unplug the satnav because somebody else was telling me too that it sometimes drives the cars "brain" crazy. Also the grounding problem was the first idea about the problem, I'm just not sure how to locate it. But first i will try the satnav thing, and let you know if it helped.

ADDITIONAL INFO: maybe it is connected that the 'hdc, air suspencion, and transferbox manual error codes are coming up now almost always?

I would get it on diagnostics - you may have issues on your CANbus (one of the many data buses in the car) probably caused by damp connections or corroded connections to one of the units on the CAN.
