incredirog Posted December 16, 2017 Report Share Posted December 16, 2017 Hi I’ve been researching this fault for a while now and it’s only recently I’ve been able to narrow it down. I have a 2003 184 330d Touring 5sp. Ok, it t first presented as OBC losing its data and the clock reseting. Fault codes would show power on after warm reset indicating that it had lost connection to the battery. Not once did it have a problem starting or running. After a few months with it happening maybe twice a month I scanned and threw up some unusual (to me) codes from the DSC module. 005DF4 - Electrical system voltage <9V 005DF7 - Board voltage >18V Now from my limited research am I looking at the voltage regulator as faulty? The alternator is 1 year old as is the battery both Bosch. I did have a power steering incident which may have contaminated the alternator. Any input or advice would be gratefully received.

incredirog Posted December 18, 2017 Author Report Share Posted December 18, 2017 ok so I went back to basics before I pull the alternator out and checked the connections at the battery and the positive connector had a layer of corrosion on it which I buzzed off and brushed up the battery terminals for good measure applied a thin layer of Vaseline and bolted them up nice and tight. hopefully that’s it, only time will tell!

incredirog Posted February 25, 2018 Author Report Share Posted February 25, 2018 just to summarise, as I hate searching and finding threads with no end result. It’s been over two months and the fault has not returned so if you find your trip computer and clock resetting with no obvious fault codes check them out! evokid 1 Link to comment Share on other sites More sharing options...

Any input or advice would be gratefully received The fact that you follow the work of your devices is an indication that you have a math mindset. People who have a mathematical mindset are not able to write papers with which the service about which they can read more, and which have a lot of talented essay writers, helps them. Do not waste time on writing papers because you will not get from this such profit as from classes that require a mathematical mindset. Link to comment Share on other sites More sharing options...

Mia Ford Posted August 17, 2022 Report Share Posted August 17, 2022 To define it from essay writing help point of view, essays are writings in which the author freely writes about the events that he/she observes and is influenced by, without being bound to any plan or evidence. As the first essayist in the world; I see the 16th century French writer Michel de Montaigne. Link to comment Share on other sites More sharing options...
