Finally after many months of despair regarding my DSR 2016 with only 4600miles
Bike is in N Germany
Faulty bike for sale Spares or repair - Project
The story why:-
The bike is out of warranty I fully understand, however-
Intermittent problems with it from lights failing and charging inconsistencies, dealer in the UK saying they found a fault and corrected (suspect the intermittent problem was on a ‘ok’ moment) resulting in while in Portugal the bike suddenly stopped, no power at all, just dead.
(luckily for me in a car park- otherwise, on the road , I dread to think what might have happened) finding a dealer with knowledge of diagnostics is like finding hen’s teeth support from Zero - (or lack of from the manufacturer Zero) no replies from them- go to a dealer- With respect to the dealers I contacted most were very helpful but had very limited knowledge of any diagnostic other than plug the OBD in and see which, as I had to explain, only works if there is power from the battery. I searched for a dealer from forums and remembered L Otten who manufactures fast chargers for Zeros so I contacted them to arrange for diagnostic as I was in Portugal I shipped it to him in N Germany.
He originally offered to diagnose for a fixed price to determine the faults while contacting Zero, which I understand he has a good relationship with.
The first diagnosis was the battery pack output is okay with 80% charge
The MBB is faulty and probably the DC-DC . Negotiations with Zero he eventually received the two units which on connecting found that the bike still did not work, a further fault was found in the battery pack itself meaning there seems to be a fault in the battery pack itself. There is trapped badly routed cables.
Investigating further apparently with Zero it was discovered the wiring inside the sealed pack was damaged by testing the varying output voltages from the ribbon cabling.
The dealer tells me that Zero is not responsible for the battery despite an apparent manufacturing fault and they would gladly sell me a new battery for 7k plus the two modules at approximately 500 each
The battery pack is faulty which blew the MBB and DC-DC after many intermittent problems probably related to the battery pack spiking as internal wiring to the low DC output was faulty. Electronic components do require voltage stability.
A lot of rhetoric have been rallied around regarding ‘new’ technology and therefore excuses poor and deficient quality control
At least in my case a low mileage vehicle although out of warranty with a fault possibly known by the manufacturer - be careful what you buy and from whom-
