2017 Vauxhall Zafira engine rough idling when engine heats up

Have you had the car in Vauxhall dealership and a diagnostic scan carried out or is it a a non franchised / independent garage you are using ?

I am currently using my local garage but I am thinking I will need to travel a fair distance to get to the nearest Vauxhall garage as I have spent a fortune on parts that's not fixed the problem☹️

Having it scanned for fault codes and properly diagnosed with the correct equipment can often save replacing parts that may not have been needed or have not resolved the problem . Not to mention the cost the owner incurs . Rightly many people are sometimes loath to use dealerships as they are often more dearer for repairs , but sometimes better to bite the bullet and cheaper in the end by doing so .They may also have TSBs ( technical service bulletins ) on your problem which are not available to non franchised garages . Not having a Vauxhall garage near you is understandably a big inconvenience .
