Diagnostic Consultation and Engine Carbon Clean – Ford Fiesta 1.6 TDCi (2010 – 86,298 miles)

⚠️ Vehicle not as quiet, smooth, economical or responsive as it once was? Issues you need to diagnose?

Here we have a Ford Fiesta 1.6 TDCi (2010 – 86,298 miles) booked in by a returning customer after we did his Mondeo a few months ago.

Running well enough, but the owner had a couple of niggly issues to diagnose and given he saw a nice recovery in fuel economy with his last vehicle wanted to get this one cleaned up and checked out also.

🔎📊 Initial diagnostics showed some historic codes which we documented and cleared and monitored what returned. The owner had issues with the A/C system running hot and then cold and the diagnostics confirmed a permanent code for the Cabin Temperature Sensor. Other that that there were no real issues on the diagnostics, but when revved there was a very slight judder as the revs returned to idle which may suggest some EGR restriction.

🔎🔎 Closer investigation of the live data for the EGR showed opening and closing when expected, but the readings were a little erratic – we advised the owner to keep an eye on the judder and if it gets worse to get the EGR checked.

👨‍🔧 On with the clean and the bass note in the engine soon diminished as the vibration subsided and by the end was lovely and quiet, smooth and responsive again.

🗣️ ‘Excellent thank you. A lot smoother through the gears and seems to be quieter. Found where the cabin temp sensor is, behind the dash, very awkward to get to. Nice to meet you again.’
