From months of guessing to full boost! 🔥
This 2016 Mazda CX-5 2.2 came to us after having a new vacuum pump, two new turbos and still hardly any boost from the little turbo, along with smoking and a rough-running engine.
The car had previously had a DPF removal and delete, which immediately made diagnosis much harder because there were no relevant fault codes showing. 🤦♂️
We started by sourcing genuine original software and returning the ECU to factory specification. Instantly, the DPF and EGR faults appeared, confirming exactly what had been hidden in the previous file.
After applying our correct DPF/EGR solution, the smoke disappeared — but the boost issue remained.
Eventually, the EML came on with P2262, a well-known fault on these engines. Checking the previous software revealed that P2262 had actually been deleted from the ECU, explaining why nobody had been able to find it! 🤬
We removed the sensor associated with the fault and found it completely melted. The metal pressure pipe was also heavily restricted with carbon.
We stripped the pipe down, heated it up and blew it through with compressed air… and P**F! 💨 A huge cloud of carbon came out!
After cleaning everything and reassembling it, we had pressure back through the system. Luckily, we had another CX-5 in the workshop, so we could temporarily borrow a known-good sensor.
The result? FULL BOOST BACK ACROSS THE RANGE and the car finally driving exactly as it should! 💪🔥
New sensor ordered and this one should be ready to go tomorrow.
After months of being misdiagnosed, we finally found the real issue — proper diagnosis beats blindly throwing parts at a car every time. 🔧
And once the customer knew the car was finally healthy, they decided to go for a Stage 1 remap to finish the job. 🚀
Another tricky one solved! ✅
