I've already checked that with an auto electrican and so has the Mobilio-Life technician. The drain during normal running and when "asleep" is within normal operating parameters.
I cant get 2 weeks left and locked from my SL,,nearer10 days and consumers on
I handed the Mobilio-Life report to me dealer. They still insisted on conducting their own tests. Not only is it costing them money for labour to investigate a fault that has already been investigated, at their cost, I have now the extra costs of taxis etc. to consider.
With the latest generation of battery tester, using one of those would have been a cheaper alternative for both parties concerned
I guess they are trying to 'find'a fault so they can say the battery is fine but there is an electrical problem causing the drain.
"Unfortunately the Mobilo technician only has access to limited facilities on his van whereas we at the Dealership were able to run a FULL test and have concluded that your what not is drawing power from the thingamee and this has now damaged your battery beyond repair. You will need a new battery at 135 pounds, plus six hours labour for us to come up this bulls**t"![]()
You've voiced my hitherto unspoken fears. They will have a fight on their hands if they try this.
I came unstuck on this badly and I should have known better , after my car had been standing for 2 weeks the rear AGM battery was down to 7.5 volts,, a current check showed 250m/a,, I went looking and there was no fault,, all it was, was that nothing could re set and was stuck, so everything struggling.
Upon charging the battery there was no fault.
Basic rule number one in everything that I have repaired in my life === power supply,, in this case the battery was low and nothing else.
once batteries get down to 11.75 volt this is the point where consumers get switched off the fall is rapid and in the case of a AGM battery it takes 12 hours at 6 amps to get it back up
I have a 2005 W211 displaying battery fault and telling me to visit workshop even though it a new battery I just bought for £140 and I cannot reset this display. I took it to stealer a number of times and finally they diagnosed it a wiring fault.
Am I right to say that the stealer not seeing a battery not bought from them will invalidate your 3 years warranty?![]()
Update: 10:30 11th April. Dealer just phoned me to say they have spent 6 hours diagnosing the battery drain and identified as one of two SAM units. Now need to find out which electrical control unit running through that SAM is causing the drain.
They said, as my MB is over 6 years old there is a discount of £40 an hour on labour, making their labour charge £80 + VAT and an unspecified discount on parts.
I responded that I had not authorised 6 hours of investigation and, if they had rung me to say they wanted to do that I would have said no as I can take it to an independent to diagnose the fault at £45 an hour, not £80. They have admitted they should have got my permission and promised to come back to me on the number of hours charged.
I'm quietly fuming at the moment...
