â ī¸ Vehicle not as quiet, smooth, responsive, economical or emissions friendly as it used to be?
đ Here we have a Vauxhall Insignia 2.0 diesel (2015 – 79,751 miles) booked in for diagnostic consultation and Engine Carbon Clean.
âšī¸ The owner had noticed the fuel economy dropping off over time, the engine getting noisier and the exhaust getting smellier.
đ Initial inspection found no obvious issues in the engine bay.
đģ Initial diagnostics found lots of code history including cylinder pressure codes (glowplugs), IAT and oil pressure sensor codes amongst others. No active codes though – we documented and cleared these for the owner and none returned during the booking.
đ Live data monitoring showed decent values all round with coolant temperature at 97°C, low DPF soot levels and recent regeneration and good average distances between regenerations.
đ¨âđ§ On with the clean and it soon smoothed out, quietened down and by the end it was quiet, smooth and responsive again, with a documented set of intermittent issues to monitor/address.
