Is there something up with the Opel Insignia?

Why is the engine in the Opel Insignia giving so much trouble? And reviews don't seem too good on them.

Hi Bridie,

It depends what you mean by ‘the engine’, but we’ll assume for now that you mean the most commonly-sold Insignia, the 2.0-litre CDTi. As far as our research goes, these are reasonably robust units and only have three common areas for faults – the diesel particulate filter, which, as with any diesel engine, can get clogged up if you don’t do regular long journeys; the turbocharger, which can fail; and the dual-mass flywheel,  which can also fail.

Now, fair enough, turbo or dual-mass flywheel problems can be very expensive, but the Insignia is far from alone in suffering from those issues, and it doesn’t seem to be that the problems are endemic, nor even all that common.

When you say reviews, do you mean comments on internet articles? Not the same thing I’m afraid – someone who can be bothered to comment online generally already has a problem with their car, so you don’t get to hear from those who’ve had faultless miles of service. It’s called confirmation bias.

Instead of ruling out a given make/model, it's best to take a close look at examples that are offered for sale.
