🚗 Here we have a Mazda CX7 2.2 diesel (2010 – 72,782 miles)

ℹ️ The owner had just bought the vehicle and was aware that the turbo had gone and been replaced prior to purchase. As such there was lots of blue smoke (which we informed him an Engine Carbon Clean wouldn’t clear, but it would eventually clear up over time as it burned away). Otherwise he wanted to get it checked out and cleaned up.

🔎 Initial inspection found a rattling noise from the front which sounded like something vibrating due to the engine vibration. Turbo was breathing easily which correlated with a replacement.

💻 Initial code check found some historical codes that we documented and cleared and the only returning code was related to the A/C system – solar radiation sensor circuit.

📊 Live data looked good across the board and one thing of note in the DPF statistics was fact that there was only 1 regeneration event logged over the lifetime of the vehicle. That would suggest that the data was cleared just prior to purchase and given the turbo had dumped oil through the system it is likely it filled the DPF with oil and that was also replaced with the turbo.

👨‍🔧 On with the clean and although the response was already there due to the new turbo, the bass note was present from a dirty vibrating engine. This soon quietened down and smoothed out and the rattling noise soon stopped. As the overall volume diminished we could pickup a ticking noise from the additive pump – something the owner can get looked at.
