Maintenance / Re: Service 2017 Mazda 3 costs
« Last post by paul.turton on Yesterday at 09:20:35 PM »
I too paid £600 for a 3 year service plan and thought £130 was a little steep for a first service, I don't think the dealership meant to invoice me however thinking back to the days when I had motorcycles that was peanuts for a first service.

My car had the suspension lowered yesterday. I was going to buy the Mazda ones from Jennings but then I found a set of progressive springs on eBay that were in Germany. They are excellent quality and made by a company called Vogtland. Mine were for the Saloon but they fit the Hatch too. My car is lowered by 30mm at the front and 45mm at the rear.The car handles really well and has no issues with speed bumps and suchlike.

The end of story is that PCM has no ground on those 2 sensors. So far, only this is the problem woth PCM and I won't change it. I grounded the ECT at body but may do so at another port st PCM and the car starts and drive very well.
 For good measure, I changed the ECT today, even though the old one is working fine.

Well, I finally got the lowering springs from Germany and got them fitted yesterday. The car has been lowered by 30mm at the front and 45mm at the rear. I am very happy with the look of the car and with the improvement in the handling. That is probably all I will do for now. Any comments or questions would be welcome.

Thanks again.
It is electrical. It starts at times and it doesn't other time.
ECT works and shows temp when I ground it.
No ground and reading is -40C and fan turns on at full blast and remains on for several minutes ater key off. Typical for faulty ECT cuircut.
There is no ground at PCM.

The million dollar question is if PCM has to have a ground at all times or if a relay switches the ground when requred, but that relay is faulty? Or is it that PCM is faulty, in which case I can simply ground the ECT and IAT to body and drive like that?

I started to take the loom appart, but it is so  nicely done that I think not to bother. There is nothing wrong with the ECT cables, other than not having a ground from the PCM. The ground for ECT and the ground for IAT/MAF are interconnected, but not connnected to other sensor' grounds and those 3 grounds at ECM.

I gather that in some cars ECT is grounded at the body, at others - MAF and other sensors can have separate ground not at PCM, but what is it on my Mazda?
To ask Mazda Motors would be a long process (know from past experience). They even now say on their  website for technical enquiries to ask the local Mazda garage.

If I remember correctly the system is based on a pair of cameras behind the rear view mirror. Was the windscreen clean at the time? Dirt over the sensors doesn't tend to be good for this sort of thing.

Vehicle Electrics / Forward Obstruction Warning Lamp occaisionally showing amber
« Last post by Ian345 on November 14, 2017, 01:22:54 PM »
Hi all,
2017 Gen 3 1.5D Sport Nav.
Has anyone else experienced the Forward Obstruction Warning Lamp occaisionally showing amber?
It has happened 3 times now, for about 5-15 minutes and then goes out. This is over about a 6 week period.
Reluctant to take it all the way to my dealership for them to say no fault found (as I can guarantee it won't be on when I take it there)
