Is the Vauxhall Combo reliable?
The Vauxhall Combo has 3 known faults in our database across 2 generations, 2 of them rated high severity. The most serious are engine (camshaft bearing bolts can vibrate loose, causing camshaft fracture) and engine (diesel Particulate Filter (DPF) regeneration issues on the 1.3 CDTi engine). None of them makes the car a bad buy on its own; the risk is a seller who knows and says nothing.
That is a count of the faults we hold, not a reliability score. Popular cars get written about more, and a newer generation has had less time to show its faults.
Which Vauxhall Combo years should you avoid?
No year is a write-off on its own. What matters is which serious faults a given year and engine can have, and whether the car in front of you has had them fixed.

Diesel Particulate Filter (DPF) regeneration issues on the 1.3 CDTi engine. Excess diesel fuel, intended for regeneration, can seep into the sump, raising the oil level and potentially causing the engine to run on its own diluted oil (runaway), leading to catastrophic self-destruction.

Vauxhall Combo buying questions
What are the most common Vauxhall Combo problems?
Three stand out. Engine: camshaft bearing bolts can vibrate loose, causing camshaft fracture (typically 50000 to 90000 miles). Engine: diesel Particulate Filter (DPF) regeneration issues on the 1.3 CDTi engine (typically 50000 to 100000 miles). Engine: the oil cooler, integral with the oil filter mount, uses engine coolant to cool the oil (typically 70000 to 120000 miles). The full list above is grouped by generation, with typical mileage and a rough repair cost for each.
Which Vauxhall Combo years should I avoid?
No Vauxhall Combo year is a write-off, but the Combo C (2001 to 2011) carries the most serious faults: engine. The Combo D (2012 to 2018) has none rated high severity. Year matters less than whether the specific car has had the known fixes, so check the history for them.
What should I check when viewing a used Vauxhall Combo?
Ask the seller about the engine faults on this page and whether they have been fixed, with invoices. On the test drive watch for engine running rough, rising oil level on dipstick and oil in the coolant header tank (mayonnaise-like residue). Read the MOT history for repeat advisories, then paste the advert into the free check, which reads it against all 3 known faults before you travel. Check a Vauxhall Combo advert →
What is the real MPG of a Vauxhall Combo?
Owners report 44.2 mpg on average across the Vauxhall Combo engines with data, about 79% of the official combined figure. The gap between official and real-world economy varies a lot by engine, so the Real MPG page lists every engine and generation separately, from 73 owner submissions.

If you used to check the Honest John “Good & Bad” section before the site closed in 2026, this page is where that information now lives. We rebuilt the Vauxhall Combo owner-report history from the archived Honest John dataset, added our own research, specialist and owner-club sources and DVSA recall data, and we keep it free. Each fault above is badged with its source. The same data feeds our free advert check, which reads a listing against every known fault for the exact engine and year.
Knowing what a Vauxhall Combo goes wrong with is half of it. The rest is reading the advert and checking the car's history before you hand any money over.
