I’ve had many situations with “specialist” that did a poor job. Probably why I started doing more things myself.

 

Ok everyone a very late update to all this. After about 4 months the codes came back for cat problems and the business that did the gutting of the cats and the delete was out of business or at least their phone was disconnected. Being totally skint and the car was actually running ok I just left it, I don't have the knowledge to do much myself. it did pass an mot last year so...Now, with a bit of a recovery after covid, I can look at getting it sorted. What can I do though, I can't imagine a tuning company will look at it after someone else had a go and didn't do it properly? What can I do?
