Hello all i posted the other day about my shitroen c5 2.2HDI failing emissions and was told by local motor factors to use https://www.dipetane.com/motorists/nct/ i put half a tank of shell vpower diesel and 1 litre of Dipetane ... and took it for a blast yesterday red line is only 5000rpm so just held it there untill no more smoke... guy rang me today and said emissions past and could not believe the difference and my 2.2hdi has 180000 no DPF and No Cat... ecu been mapped to not see DPF ...

happy as fuck
Andy
