Hi No its not the build date it can be built months before it's registerd but the VIN number identifies the car and you can have that checked by a main dealer Against the Mazda data base if it was built after this problem was sorted at the factory.
The reason i say most problems are sorted from March 14 onwards is that my old 6 a 175 bhp auto sport nav reg March 21st 2014 When i had that checked it showed that it was built 20000 cars after the problem was sorted so a rough guide yes but it was some base line to check from at the time as i didn't have everybodys Vin number that asked this question but once into March 2014 most vehicles seem to be safe infact i have not heard of a 14 plate with this problem And as yours was registerd after mine i would think it was safe but i would still have it checked at a main dealer. Hope this helps.
cheers steve

Hi everyone

i started looking for some online support for an issue with my own M6, built 2012 registered 2013. VIN JMJZG...119488. 53500 miles.

In the 37500 service i had some remedial recall work complete that involved testing the braking system which involved a known fault and I received a recall notice for this. They found nothing and i got the cost of the oil removed from the overall cost of service that I was pretty happy about.

I assumed no problems.

However, at the 50,000 mile service the garage notified me of a braking problem. (I used different garages, but both Mazda dealerships)

They changed a major brake component (servo?) at no cost and then advised me the camshaft and turbo were also worn and would need replacing. Without even asking, they had a chat with Mazda who wanted to see the details of the report on some automated report/output, but they agreed to pay for 90% of the work and parts.

I was pretty happy with this bearing in mind the car had done 50,000 miles. However, i decided it was better to simply try and get a part-ex on my car for another as spending hundreds of pounds on a car that I was going to dispose of within a year anyway seemed madness.

My reason for posting this reply is that my car seems to fall outside of the VIN range that has been referred to yet Mazda are happy to replace the parts and pay for the work (up to 90%) so it seems to me that the issue could have been identified earlier and that it affects more cars than first thought???

Not sure this is of value, but hopefully it will help others as they may be getting outside of warranty and being charged for the repairs which my garage advised would be over £2700!!!

how your VIN fall out outside the range? please read carefully all info provided in thread, affected VIN number are up to 148781. there have never been any other range for Mazda 6 GJ

did i read that the VIN numbers started at 148781?

what number do they start from, is it zero???

[damtom85]

no. VIN numbers are up to 148781. so it means the last car with faulty engine has VIN ending 148781. so your is affected

In fairness to Terry, there are two VIN ranges being referenced in regards to this issue. I think the range Terry is talking about is the one regarding the stalling recall that has been associated with the camshaft issue but is arguably a separate issue...

Damtom's range is the one to note...

thanks for clearing that up!

i am going to have a chat about getting the work done and paid for 100% and keep it for another year.

As far as we know there is no starting VIN so it means any Mazda 6 diesel can be affected prior to 148781

Just to be clear (as mud) Ross posted this link for all M6 Gen 3 problems https://docs.google.com/spreadsheets/d/ ... d=66939474 which gives a START VIN of 148781, but no END VIN for the camshaft problem.

This is the link to find out all official UK recalls http://www.vosa.gov.uk/vosa/apps/recall ... search.asp but to date DVSA (new VOSA) do NOT show any recalls for camshaft,Turbo,Vacuum Pump or braking problems.

Other posts, both here and elsewhere, do give a start VIN and the END VIN of 148781 for the vacuum pump problem, which has been attributed to the faulty batch of unhardened camshafts.

This TSB, sent by Mazda to dealers in secret, outlines what they must do if owners/drivers report loss of power and even worse, White Smoke from the exhaust. https://www.google.co.uk/url?sa=t&rct=j ... 3327,d.bGs it even shows images of what an OK camshaft looks like and one that was in the faulty batch and therefore worn earlier than it should.

As this TSB was originally issued in September 2014 and revised in Feb 2015 (as shown on the TSB) and in only vague terms mentions the VIN range and build dates, it is therefore a matter of conjecture how much Mazda actually knew when the VIN range started. Especially when you consider that VIN numbers are issued centrally to run in order, no matter at what factory the engine and/or car was manufactured in. I believe at that time M6's were made both in Japan and in other parts of Asia, so it would be logical to assume that parts for those cars were also made in different locations as well.

It would also be logical to assume that for at least a small period of time, that both 'Good' camshafts and 'Faulty' camshafts were in the relevant factory/s at the same time and thus available to be picked by the workforce in perhaps a random manner.

To my knowledge, nobody has publicly 'aired' this hypothesis, but it certainly would explain why a definate official camshaft recall has not happened up to know. However, Mazda must now be getting very worried and this impending global recall of 2.2D cars built between 2012 and 2017, allows them to satisfy the motoring world and public that they have done all they can to identify those cars with defaults. The biggest thing for any Japanese company is to 'lose face' and by doing this they think they won't.
