I have a 2014 CX-5 SE-L Nav D 4x4. Had it for 3 years and no issues with oil. Recently I got a warning message about low oil pressure and red engine light came on. Garage serviced it, advised oil filter blocked, so changed the oil and installed new oil filter. Two days later the error message returned. It goes off after I switch the ignition off and might be another couple of journeys and it comes back on again. Can anyone give any advice on what the problem may be?

 

Book it in with Mazda.

 

hello, I’ve currently got this issue with my 2014 Mazda, did you manage to get this resolved / what did you do? I’ve also changed oil and the filter

 

This generally can't be problem solved duplicated. For one thing there are completely different variables between his Mazda and yours. If you are experiencing the same thing you should see a service shop of MAZDA dealership service ASAP.

What we did not get from the original posting was the ECU information. Without that extremely valuable information there you can guess all day long what the resolve was. I might add that at the first sign of the RED dash light the engine should have been turned off not started and defiantly not driven again and the vehicle Towed to a service shop!

Do you have a diesel?

Common problem unfortunately with the diesels. Book it in with Mazda, they have plenty of experience with the diesel engine issues.

 

What could be causing this? I have the same issue on my 2017 2.2 Skyactive Diesel. Changed oil and filter, changed oil pressure sensor and problem still there.

Could it be a blocked oil strainer? How much would that cost to change at a Mazda dealer?

I notice there are a few small lumps of carbon in the rocker cover when I look through the oil filler cap area. Not good

 

Not sure if this is your issue, but...
Many Japanese vehicles do not have the exact fill levels some measure a bit high some a bit low.
My CX-5 requires roughly around 10 ounces or 0.295 ml or so to keep the light off.
I had a Honda that did the same, though the amount was different.

 

Thanks Lobstah,

The dipstick is a touch under full but I am still getting the red oil pressure light and check engine (P055F).

I read somewhere that after performing an oil change, you need to do reset the oil data on the CX5 2.2 Diesel. If this procedure is not carried out, what might happen?

 

I can't answer that as I don't own a diesel, someone else like Grim might chime in on that.

 

I paid Mazda £200 to do a diagnostic check on my 2017 Mazda CX5 2.2 Skyactiv Diesel and it is really bad news. I have been landed with a £1600 bill to replace the oil strainer - a part that costs £25 to buy.

There appears to be a problem with this Mazda engine which the oil strainer to become blocked with carbon deposits causing P055F and P0524 error codes to come up. These codes cause the red oil pressure and yellow check engine light to come up on the dash. A little research on the Internet and Youtube shows that this is in fact a relatively common problem with the Mazdas.

The strainer is essentially a filter inside the car, which cannot be replaced without a lot of work to remove the oil sump, removal of the oil pump, and dismantling the oil pump to get to the oil strainer. The oil strainer costs just £25 but the labour made up the lion share of the cost. Why would you put a filter in such an inaccessible part of the car? Oil filters, air filters and even cabin filters are easy to get to so that they can be replaced - so why do this? Why make it so hard to replace a part that is going to get blocked? Why has Mazda not modified the engine to make this part more accessible and easier to change? Why are they happy to charge 1/4 of the car's value to replace this part - it strikes me as poor design.

This is my first and last Mazda - awful experience. Costly and stressful. Not impressed with Mazda at all. I cannot recommend a Mazda or a CX5 to anyone; in fact I would urge everyone to avoid buying this car.
