Hello everyone. I have 2016 ND 1.5. I have a strange dash problem. Some of the dash display lights aren’t working. For instance no indicators left or right, hand brake on light, cruise light, main headlights on, and several others? But some are working, like high beam, and others. The digital displays are all working fine. So some of the main dash leds are working and some aren’t? All my external electrics are fine like the indicators, headlights etc are fine. It’s the indication on the dash which isn’t working? Any suggestions please before I commence the hunt for the problem? Also please where can I fine the electrical wiring diagrams for this model please? Im suspecting poor ground, loom or connectors first? Not BCM hopefully!!! This has been a occasional issue over the last year and then dash will be back to normal, but over the last week its gone as described? The car isn’t used that much, but is kept charged by a standby trickle charger.
Update today 7th Jan!!! Had the car checked by a good reliable local mechanic. He’s checked all he can and run some diags with his tools etc. It looks like a strong possibility of the Instrument cluster as the main suspect. He took it out and cleaned the connector etc and was quite surprised that the car starts without the cluster connected? He has referred me to another specialist auto diag tech locally. Rang Mazda for a quick check. The new cluster is £1702.00 (part ref: NB2V55471C) and would need to come direct from Japan, with no lead time available?? Will see what the other diag guy says when I take it in later this week, pending weather. I feel sorry for all other ND1/ND2 owners of the future at the possible high costs they/we will encounter, if we cant get an independent dash/cluster specialist to provide lower cost repairs of this part? The MK4 cluster is an obvious weakest link part and will become a more expensive repair item in the future I feel??? Perhaps putting people off buying one?
I’m a former eperienced electronics eng’r and quite dismayed at this situation as this cluster could possibly be so easily repaired if we had the PCB/circuit diagrams to aid repair? It’s most likely a solder dry joint or IC component failure? It’s a simple 2 layer pcb, I understand. So I am very tempted to examine the cluster further internally? I’d be very interested in the actual failure rate of this cluster for MK4’S? Does anyone have any info on PCB/circuit diagrams etc? Probably Mazda confidential info? See this tear down examination. As cars get more advanced so does the ability to repair them cost effectively and we are solely reliant on Mazda service dep’ts, who are quite happy to give customers large repair bills once a car is out of warranty to help the profits of the independent dealerships? I think mine will be repaired and then sold on unfortunately!!
Update 13th Jan
So after another recomemnded auto diag guy had a look, he suspects the cluster is faulty internally. Have booked it into Mazda Telford for a diag check at £180??? I asked about the situation if they diagnosed the cluster and ordered one, then fitted the new one and it didn’t fix the problem, then would I be charged for the new cluster? The young lady on the service desk said usually the customer? I think I will having a more detailed conversation with the service manager about this when I drop it in to establish the situation? I am a little concerned at the diagnostic skills.of.Mazda technicians with such a strange fault? Any comments folks, appreciated.
Please can anyone who sees my update from today 13 Jan on the post, just make a brief comment to so I know that people are seeing the updates on the forum.Cheers all.
Update 28th Jan
Be warned, the ND1 can be expensive. Get a good warranty cover, their shiiite. I had a 2016 with only 14k on the clock with a Full Mazda service history and the Instrument cluster failed…£2k to repair.The Mazda garage told me a customer with a Mazda CX60 fancy 4x4 which had a similar problem and only 6 months out of warranty had to pay £2.5K to have the instrument cluster replaced?? As they advance the fancy electronics, then the more expensive it gets for us the customer!! Ive seen later models 2019+ ND mk2 models needing the cluster replaced and get qouted big bills.
Update 6 March
Now Mazda are saying the cluster is not in stock anywhere, even Japan. What sort of company is this, the car is only 9yrs old and they cant provide parts? Might have e to consider a second hand one?
