Well, it’s heart-bolstering that they’ve publicly admitted it didn’t work and are removing the restrictions:

I'm the owner of Mazda 6 diesel SPM CD 120TE, 89kW, 10 years old, 170k km.
Last week yellow check engine light started to blink for few seconds and the engine behaved strange i.e. I couldn't accelerate the car for these few seconds. Then I turne doff the car and after 1 minute I started the car again and without any problems I drove the car few miles. But day after, again yellow check engine light started to blink for few seconds and the engine behaved strange i.e. I couldn't accelerate the car for these few seconds.
Then I gave myMAZDA 6 on computer testing which shown these 2 problematic codes : P0304-FF-PCM(Cylinder No.4 misfire detection) and P0342-FF-PCM (CMP sensor circuit low input).
Can anyone help asap with the clear explanation what is most likely the reason for these problems and codes and what is the recommendation to do to repair the car cheaply?
FYI, below is the explanation of these 2 problematic codes : P0304-FF-PCM (Cylinder No.4 misfire detection) and P0342-FF-PCM (CMP sensor circuit low input).
Thank you verymuch

DTC P0304 Cylinder No.4 misfire detection
DETECTION CONDITION
The PCM monitors the CKP sensor input signal interval time. The PCM calculates the deviation of the interval time for each cylinder. If the deviation of the interval time exceeds the preprogrammed criteria, the PCM detects a misfire in the corresponding cylinder. While the engine is running, the PCM counts the numberof misfires and calculates misfire ratio for each crankshaft revolution. If the ratio exceeds the preprogrammed criteria, the PCM determines that a misfire,which can affect emission performance, has occurred.
Diagnosticsupport note
• The MIL illuminates if the PCM detects the above malfunction condition in the first drive cycle.
• FREEZE FRAMEDATA is available.
• The DTC isstored in the PCM memory.
POSSIBLE CAUSE
• Fuel injector malfunction
• CKP sensor malfunction
• CMP sensor malfunction
• Inadequateengine compression due to engine internal malfunction
• Related connector or terminal malfunction
• Related wiringharness malfunction
DTC P0342 CMP sensor circuit low input
DETECTION CONDITION
The PCM monitors the input signal from the CMP sensor and the CKP sensor while the engine is running. If the input signal from the CMP sensor is not input while the PCM detects 255 pulses from the CKP sensor, the PCM determines that there is a malfunctionin the CMP sensor circuit.
Diagnosticsupport note
• The MIL illuminates if the PCM detects the above malfunction condition in the first drive cycle.
• FREEZE FRAMEDATA is available.
• The DTC isstored in the PCM memory.
POSSIBLE CAUSE
• CMP sensor malfunction
• Connector orterminal malfunction
• Short to GND inwiring harness between CMP sensor terminal A and PCM terminal 81
• Short to GND inwiring harness between CMP sensor terminal B and PCM terminal 55
• Open circuit inwiring harness between CMP sensor terminal A and PCM terminal 81
• Open circuit inwiring harness between CMP sensor terminal B and PCM terminal 55
• Improper CMP sensor air gap
• CMP sensor pulsar malfunction
• PCM malfunction Read more
before you replace them remove the injector rail with the injectors in it , then strip down the rail and refurb the injectors first remove the rubber gromets and go to your local hrdware store to see if they have any that size and thickness then clean the injectors with petrol and a toothbrush and a needle and also use a womans emery board to clean the wire connectors then once that is all done put the new rubber gromets on then rebuild the injector rail and refit to the car and turn over , the engine light might come back on but this time it should be on costant which is a good thing , it just means you have to get a diagnostic machine plugged into your car to swith the light off , hope this helps .
just brought a new car for my daughter volkswagen up... Read more

Hi, could someone tell me if the many problems that the old Focus 1.6 diesel seems to suffer from ie. turbo failure and injector leaks still apply to the new shape one 2010 onwards. Is it the same engine or have Ford solved these problems. Thanks for any information given as i am thinking of buying one of these and don't really want to be paying out for expensive repairs. sparky100. Read more
I have replaced the thermostat recently on my punto but my car is still overheating. It does not go up fully into the red but very close to it . Heaters blowing cold, any one offer some help please. Read more
It also helps to park the car facing uphill and bring the revs up, Open the bleed nipple and any air out and close the nipple before letting the revs drop. Successful bleeding can take several attempts-don't underestimate the amount of air in there!
My daughter bought a used Peugeot 207 6 weeks ago from an independent (well respected) local dealer. It's an 07 plate with 65,000 miles and was sold with a 3 month dealer warranty.
She noticed a noise from the clutch today and took the car to a Peugeot dealer to look at. The diagnosis is that the thrust bearing is failing and should be replaced - with the whole clutch needing to be replaced at the same time. She has contacted the selling garage who says that replacing the bearing may be covered by the warranty, but the whole clutch certainly won't be.... Read more
That's a great result ,it's very unusual for a finance company to get involved in the way you describe ,well done .
As a current topic shows, there's quite a lot of confusion about the names used by different manufacturers. It's an area which interests me and I've been trying to list them all. Here it is. I'd appreciate any suggestions which will help me to get the list right.

Petrol-electric or diesel-electric can be more efficient when combined with regenerative braking and energy storage - i.e. battery.
The battery is a middleman-like all middlemen, he always takes a cut. Sometimes he earns his cut, but you want to cut him out of the equationwhere possible. Hybrid is more an alternative means of propulsion than transmission. The regenerative braking capability is a no-brainer because electric motors are usually fully reversible as generators. The contribution to economy isn't as significant as it might seem and isn't the raison d'etre of hybrid, but it is a feature that's easy understood by the public.
hiya ive just purchase a 307 54 plate and it started coming up with the oil light and a message saying oil pressure insufficent? the oil level is fine though? now today, another light came up on the dash and a message saying anti pollution fault!!! what could these mean please as i dont want to be fobbed off by the garage and have 3 young children i drive about and a job as a carer so need the car to be safe!! :-( thanks xx Read more
Take it back from where you bought it ,it could be a faulty sensor but more likely to be something much more expensive,

Maybe 'impossible' was the wrong word. I might have said 'very difficult to keep going for a long time'. I guess people working to a fixed shift pattern could do it, but flexible working must lead to independent travel.
