Confirmed: A Genuine Vauxhall Recall Covering DPF Diagnostics on Diesel Mokkas — Vauxhall Mokka Exhaust System
Vauxhall has confirmed a recall covering certain Mokka diesel models (alongside the equivalent Astra) for an error in the exhaust gas temperature diagnostics that can prevent the Diesel Oxidation Catalyst (DOC) and Diesel Particulate Filter (DPF) from functioning correctly — potentially resulting in a blocked DPF and DOC. The remedy is a free Engine Control Module reprogram carried out at any authorised Vauxhall dealer. If you're looking at a used diesel Mokka, checking whether this specific recall has been actioned via your registration is genuinely worth doing.
