Good idea, will email the seller.
That ELM327 connector is only £10 so Ive ordered one to give it ago. Works with Mazda diesels 2004 onwards and many other cars and can read and clear DTCs. Unlikely it will let me do DPF regen (I think I need VCM module for any in depth diagnostics) but will be useful to read codes and other live data for troubleshooting.
I did come across that "Tips and Tricks" page a few days ago and gave it a go yesterday with no conclusive results
Tried DPF regen, DPF reset, Oil reset, Injectors recalibration and none of the steps worked.
I then disconnected the battery for about 10 min, connected again and immediately tried DPF regen procedure. RPMs increased to ~1750 and it looked like the DPF regen process had started. After exactly a minute engine RPM dropped to under 1000 and idled. I thought that I accidentally stopped it by turning the heating/radio on so I tried DPF regen again and it would not work. Tried DPF reset and then regen again - no joy.
So I tried battery disconnect -> DPF regen - Same result - DPF regen starts and stops after exactly 1 min.
I then tried Oil change reset / injectors calibration process and never saw glow plugs lights lit up as described. Tried each process after battery disconnect - no joy.
Took it for a drive and the car is still lacking acceleration and power.
I am now paranoid and think that the previous owner messed with the dashboard lights to get rid of DPF warning light so he could sell the car.
Could you tell me which lights supposed to light up and go off when the engine is started? Or is there a way to check all the dashboard lights are working?
Some more news. I called Mazda UK to get it registered under my name and asked if it was due for any recalls. They called back and said that it was and I can take to a local dealer for a free repair service.
This is the recall problem :
Recall Details for MAZDA - Mazda 3, 5 6 and 6 Wagon (fitted with RF Diesel engine)
Apparently ECU needs to be reprogrammed.
I am now hoping that the dealer will do a proper check up on the car with official Mazda diagnostics tools and tell me what the problem is.
Happy new Year to you btw
