Year of Manufacture *: 2007 Engine Size and Code *: 1.4 VTi 8FS ( Optional ) Scanner Used: Solus Pro ( Optional) Fault Codes: P1675, P1676, P0562
I have the above vehicle in with a loss of battery charging. It was diagnosed by the breakdown service as an alternator problem but I need to confirm that. The warning light doesn't come on untill the engine has been running for a while. This may be a similar system to the Ford Smart Charge but only has one wire going to the multi plug. I have no wiring diagrams or pin data for this but the same alternator is used on some of the later Mini's and the diagram for that says that the wire goes to pin C38 but doesn't give any waveform for it. Can anyone give me some advice on testing this and what I should be seeing at this terminal. I have attached a couple of captures and as you can see the waveform is a bit erratic but doesn't change with any load put on the battery. I also have P0014 Exhaust camshaft dephasing coherence but I have ignored this for now. On clearing the only codes to return were P1675, Alt open circuit and P1676, Controlled alternator value received incorrect on BSS network. Many thanks for any suggestions. Regards to all, Bryan.

Hi Bradley, Thanks for the suggestion but yes I have (by testing the voltage at alternator body to B+). I have taken a waveform today with the control wire disconnected and it is the same (about 15% duty cycle) but is steady all the time. I have taken the plunge and ordered a replacement, so will post waveform and results tomorrow. Regards, Bryan.

Many thanks for that excellent info Dave. I have replaced the alternator and then had another look at the control wire waveform. It didn't look any different except for a slightly higher amplitude due to system voltage being higher, but the duty cycle went from about 15% to just over 30% (fluctuating to 37% under load). The vehicle was towed in for the battery/alternator problem so I will let the customer know that that is fixed and ask what he wants to do about the P0014. I suspect he may want to book it in for a more convenient time. As footnote for future searches, these have a one way clutch decoupler on the alternator and I have previously had VAG vehicles fitted with these that have lost the drive. This was the first thing checked on this one but it is very easy to overlook. Thanks again. Bryan.
