We use a garage, because it's an absolute pig of a job on the Octavia specifically.
There were no problems until the recall to have the ECU reprogrammed in the aftermath of the VW emissions furore. After that it was never quite the same (and anecdotal evidence suggests that there are many people in the same boat), not helped by the fact that almost all our driving now is short distances. It's completely the wrong car for that, but changing it right now isn't the sensible option.
If it makes it through the next two or three years though (when the children are both finished with university), we will consider its job done and when it falls apart we can replace it with something more suited to our lifestyle. Perhaps a dumper truck
