Engine/Transmission/Powertrain/Exhaust / Re: 2018 "PCM Reprogramming Campaign"?
« Last Post by mareng73 on January 11, 2019, 09:48:52 pm »
I had a letter about this in August.

"Your vehicle is now required to be installed with the very latest and improved engine calibration software. Software will also be installed to enhance the accelerator response as well as provide engine noise reduction".

This stinks of dieselgate - Mazda aren't going to be offering a free improvement in accelerator reponse and noise reduction, are they? So has anybody else had this done?


Yes I had it done supposedly  on a 2014 whilst in for a service. I cannot say it improved the performance nor did it improve mpg as compared to the same time last year when I was touring, so  long motorway runs , in other words.
If they improve the emissions then in most cases fuel efficiency suffers, so a bit self defeating in my eyes.
I will have to start using  Shell V or BP Ultra again see if the consumption improves.

Anybody else seen a detioration since the PCM upgade?
The other thing they were supposed to check was the blowing injectors, rather than reseat them with new washers and correct torque. They are waiting until it happens, causes damage to the engine , then expect you to pay for repairs.

Steering/Suspension/Brakes / Re: Mazda 6 GH6 electro mechanical steering failure
« Last Post by apav on January 07, 2019, 12:43:55 pm »
I think there were older posts about that. You can investigate with Mazda and compare the costs. But if the car is fine when driving, keep in mind that when you stress the power steering with continuous movement like turning the wheel without moving, then try to park, then turning the wheel again without moving, etc, it warms up so badly that it shuts off. This is on the owner's manual. When it cools down, it works again. If you have been doing this kind of parking for the last 6 years, maybe it is time for the part to fail. You should check the suspension for the tyres wear and align the wheels if the suspension is fine.

Steering/Suspension/Brakes / Mazda 6 GH6 electro mechanical steering failure
« Last Post by ytkpourv on January 07, 2019, 11:37:13 am »
My Mazda 6 GH6 (2013 with 66,666 km on the clock) has suffered power steering failure.  It's the electro mechanical type.  The other day I was parking and all of a sudden the steering started to get really heavy so much so that I couldn't turn the steering wheel at all!  I turned it off and waited 5 mins and tried again and it worked but only for a minute and the same thing happened.  Brought it to my local indy garage who said there wasn't any known recalls of this type and so the only option was to have the whole steering unit sent to a place in Dublin (Ireland) for a refurbishment as a new Mazda unit would have been around €1800 excluding fitting.  Have to wait 2 weeks now for the part to be mended and returned to the garage for fitting so I'm looking at around €1200.  Has this happened anyone else?  Am I going down the right track here or is this something like a design flaw that Mazda should cover?  PS my front tires were wearing down crazy on the outside (not inside) if that might have anything to do with it like cause or effect.

Discussions about DPF / Re: Discussions about DPF

MOT examiners are now specifically looking out for DPF removal in which case an automatic fail. The crud out of the exhaust will be the giveaway.

Is it a clicking sound ?   If so it is more than likely to be your battery on the way out.   The clicking sounds are the relays trying to close to enable starting.

I recently had the same problem with my previous Mazda 6. It was unitially diagnosed as a dodgy battery. However turned out to be the negative lead on the battery creating intermittent earthing problems.

Yes it could be the starter motor.

The fuel filter needs replacing every thing service and checking for water at every service. I replace at every second service. I do not think this can cause any noise as the engine runs fine when it runs.

CX-7 / HELP!!! Car Not Starting Right

Only just recently started happening, but is becoming more frequent. 

Go to start car and nothing happens.  I get all the normal dash lights, but no sounds, no warning lights or beeps. 

Turn car off and then back on again.  Some times it will start, other times I get a horrible sounds just like if you are trying to start the engine again when it's already started.  (hope that makes sense).

When engine does start.  Sounds & runs fine.  no problem. 

Could this be the starter motor, fuel filter or something else? 

Thanks all and hope you all have a happy new year.

Try the above link

To check it, take off cam cover, and No 1 injector, using a dial gauge ,or a long thin screwdriver through injector hole, determine TDC and see where mark is on EX cam.

Do you think cam timming  or chain

Is there any where I can get a manual for timming
