Well folks, Accord seems to be fixed. £200.
Following the advice and discussion in this forum I took the car to a local auto sparks who has a good reputation within the trade. He had the car for a day and then called me yesterday to say: “Good news, all the warning lights are out and the instrument cluster is working as it should”.
I asked him what the problem was and he told it was a dry joint to a power transistor in the instrument cluster. I was impressed that he had gone so deeply into the system.
I asked why the battery was being drained since this fault occurred – down to 7 volts in 3 days – and he told me, (I didn’t know this) that when we turn off our cars, the various systems take several minutes to shut down and, because of the fault, they were not shutting down as they should and remained powered, thus draining the battery.
He said he always waits 20 minutes after turning off such cars before checking for a leakage of current, which is what I suspected was happening, thus causing the battery to flatten. We went to the car and he showed me the present current flow by connecting a multimeter in series with the battery post and cable. It showed around 1 millivolt. And there is the major benefit of going to a specialist rather than a main dealer. They show you what is happening whereas the dealers I have met just take the car out of sight then bring it back “fixed” with a big bill.
I have just checked the voltage this morning and from 12.7 volts yesterday morning on his meter, it is now 12.65 volts on mine so it seems he was right about the cause of the drain on the battery.
I realise that I may have gone off on the wrong track over this but in mitigation, if a main dealer puts the car on his diagnostics and tells me the ABS/VSA module has gone, doesn’t charge me for the diagnostics and doesn’t want to do the work ( so has no profit motive ) then initially, I believed what he said.
Fortunately, time has taught me to take the word of no one without checking and had it not been for the excellent and knowledgeable advice given on this forum I could have taken the car to a Honda dealer at goodness knows what cost. It was suggested: “A few hours of checking at £85 per hour plus VAT”.
I guess I will have to go to the second dealer in any event to have the fuel filter changed even though the car has just been serviced again and in spite of the fact that the first Honda dealer should have changed this filter at the 75,000 service ( the car had covered around 69,000 at the time but I asked for the 75,000 as it was supposed to be more comprehensive and included the fuel filter) which was just 8,000 miles ago. It is hard to believe the filter has become blocked in 8,000 when the change interval is 25,000 so, as previously stated, it could be that the dealer’s mechanic didn’t bother to change the filter as it is a fiddly job which, I am told can take 45 minutes.
Once again may I thank all those who responded to my query and I hope the above helps anyone who may have a similar problem.
Best regards. T
