madhog427 0 Report post Posted July 27, 2021 So can was running good as gold up untill three days ago when it starte3d giving me all error codes at once including transmission failure warning then went into limp mode. It can be fine at times but will always go back to this state at some point. Also shuts of the infortainment screen speakers make weird static noise.. The othe codes are DSC, ABS,Battery termials which are fine.. Im kind of lost where to go from here. My first idea is it has to be an eletrical fault or sumthing.. It sux as its a great car when running right..170,000km on the clock.. ill include sum pics. sumeone must have seen this issue b4. It can be fine for half an hour or so then all hell kicks off. Or if i park it after a cold start and restart it this issue comes up.. Quote Share this post Link to post Share on other sites

jon dee 500 Report post Posted July 27, 2021 What he ^^^^ says. Get hold of a decent battery charger and hook it up in the engine compartment as shown in the pic. Positive lead to the positive terminal (green arrow) and negative lead to the grounding lug (yellow arrow). If everything works fine for a while and then the yellow battery symbol on the dash comes back and the problems start again, your battery is not charging off the alternator. Cheers...

Jacko 2158 Report post Posted July 30, 2021 Stop and get someone to code it, then clear fault codes. There are a few pictures on the interwebs of batteries catching on fire doing what you are doing. Quote Share this post Link to post Share on other sites
