There are different octane diesel available?
I have never heard such a noise, not on mine or the FOUR cx5 models I test drove before buying, but ALL where manual versions.
Or the brake noise, but most of my driving is with music playing.
Wind noise on the motorway is my only gripe plus the drop in economy at motorway speeds.
I have on about three occasions felt a engine jerk/misfire which I have never been able to identify just before 2K revs, I believe it could have been the change over from one turbo to the other, but its not happened for a while.
To be honest its the best engine I have ever had in any car, but I have only had 4 pot engines.
The CX-5 does appear to have a broad band of problems, I had virtually no problems with the four Nissans I've had, although that my now have changed since I last bought one.
Hi, I have just bought a CX 5 2.2 DIESEL automatic. It has the same noise you are describing and is clearly a fault Mazda would rather not admit. As a person that understands mechanics and therefore "NORMAL engine sounds" the car is for me a Brain Hammer. When I drove the test car prior to signing the purchase contract the engine sounded sweet and refined. The car I have taken delivery of is unacceptably noisy once at it's normal working tempreature. I feel cheated that the test drive wasn't long enough for the car to reach it's working tempreature and the hell noise to start, maybe that's why the test drive is so short? In all other respects the car is very good but the engine noise is unbelievable and completely unacceptable - I want my money back.
This noise is now very common on NEW CX5 diesels, I have it too, but only once the engine is warmed up as others mentioned. Many test droves won't show it up. Mazda say it is the injector noise and it is normal. Someone test drove 4 diesels and they all made the noise after a long drive. It may be normal and nothing at all to worry about, but yeh, it is very loud and wasn't present on my older model.
Hi Dr_Watson, thanks for the comment. This confirms that I am not oversensitive over this or imagining things. Have you heard or considered any ideas on trying to muffle this noise in order to make it less irritating? Apply extra sound insulation perhaps?
I had a Jeep Grand Cherokee CRD befor this one and I could hear the engine alright, but no issues with noises. I am OK with the actual engine noise of the Mazda but it is this ticking/pinging underneath that is annoying. Hope I will get used to it. I also noticed the claim about a better sound insulation with the face lift. I do not have the direct comaprison. But to rate this in some way, I would say that road noise is very acceptable, engine noise OK, but the noise from injectors apparently is not acceptable. It may be "normal" in the sense that it does not indicate a malfunction, but it should have been better insulated.I have been driving petrol cars for over 30 years and this is my Diesel cars. I will have to say that the diesel engine is way more noisy than petrol engine. Funny thing is the face lift model is supposed to have better insulation as well. I guess there is a bit of getting used to. I picked the diesel for its fuel efficiency over petrol.
The issue with the diesel is that I can no longer tell what is "normal" engine noise vs what is not normal. Ah well. Everything has a learning curve.
Your description of this noise matches my experience exactly. Judging from the comments from you and others in this thread, this is getting very close to demanding a serious reaction from Mazda in my opinion.I have owned many cars, a few diesels, Golf R32, Impreza Turbo and my old CX5 2.2 for 2.5 years. This latest model has a very refined and quiet diesel. The extra soundproofing is obvious when I compare it to my old car. I test drove a 2.0 and a 2.5 version, at low revs they are a little quieter, but once you want to accelerate at similar levels to the diesel, they are just as loud as the require more RPM to get the same performance. Overall, all models are very quiet.
The pinging noise on the new model starts once my engine is fully warmed which can be 5 to 10 mins after the blue light goes off. Before this, the engine is very quiet and refined. The problem with this noise is, it is quite a high pitch and really penetrates from the engine into the cabin. Even with music on a mid to low volume you can still hear it. At low speeds, the predominant noise is this pinging since the engine itself is so quiet. I think I will get used to it, I don't really have a choice, this car is staying with me for 5 years. I check the German and Oz forums every few days, so far there hasn't been any mention of it.

It probably isn't on every car! Considering a annual injector calibration which seems to be part of the standard service can fix it, it may be some dealers are doing this on cars before they they are sold?
Is your model the facelift model?
It's loud enough for everyone to hear, it's not that high pitched. If you have it, you will hear it! Although, it does have that phenomina where if you turn your head to the right or left when driving, you can't hear it anymore. Not an ideal solution though!
It is interesting to know that not all the cars have this pinging noise. From that I am tempted to conclude that a repair or improvement is possible. I have not yet discussed this issue with my local dealer but will of course do that in the very near future. If anyone here has some further points about the "injector calibration" discussed in this thread, then please share the information.Hi Dr_Watson. My CX-5 is the face-lift Diesel(128KW /420Nm) version. Yes. Perhaps the high pitch noise does not happen on every car. I certainly hope so after being dragged through the Accord Euro "pinging" noise drama a few years ago which Honda did find a fix at the end.
