You really at this point are on a rant
At least let new and regular members ask their question and have some of work through their problems without your negative opinionated cometary about how you feel about Mazda
WE GET IT!!!

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.

Oil pressure warning light
Hi
2,2 diesel motor was fitted first In CX-7 models, issue was that bushings under injectors was burning out due to heat, so they let left air in, building up carbon residues. Carbon was travelling down to oil sump blocking it, so warning light was coming on.
Need to inspect sump and replace bushings under injectors for new, if thats the issue, I had it on mine and it was resolved, hope it will help.
