Not sure this is specific to my Karoq, but probably other models as well 🤔

The dealer ran diagnostics on my car and satisfied themselves that they had identified the problem and provided the solution. Unfortunately, this was not the case and it has to go back again for a replacement part.

My question then is whether they automatically clear codes on the machine, or if this is operator choice, since clearly the faults returned within 5 miles of leaving the dealer! Thanks.

Clearing the fault after dealing with the issue or fault and then road testing it and checking for fault codes is just 'Simply Clever' or a necessity'. Did they road test your vehicle before handing back the keys having given you the invoice. Plus the report on the checks they did while they had the car with them?

If they didn't clear the codes how would they be able to tell they had fixed the problem?. Normally faults that have not been fixed correctly will reappear as soon as the vehicle is started or driven. The awkward faults are those where codes are logged, cleared and return after a period of time. I used to use VCDS to periodiclly check for codes, there would be codes listed which didn't result in any messages on the dashboard, that when cleared never returned or sometimes did return many weeks later, usually it was just a sensor reporting a reading that was out of spec.

Thanks guys. It's on a Skoda extended warranty, so the only invoice I get is my contribution to the overall cost, or excess as it's an insurance policy.

I get the impression that they don't recheck after fitting the new part, so that seems unwise.

It's a central locking fault based on a faulty sensor in the driver's door which thinks the door is open, then throws up faults with engine running, auto hold not working, electronic brake faulty and others.

@HowardBury Does that Invoice show all work done, time and parts used even if you are not paying. That is for your Records as the Owner / Driver. It is not supposed to be the SKODA SECRET SERVICE. Lose lips cost lives. Yet Dealerships seem to think it is all on a Need to know basis and customers need not know.

The invoice only says "replace driver's door lock", and even that was just a recommendation from the initial diagnostics check, so no actual record of the work done.

I should also have mentioned that the door lock clunks repeatedly due to the fault, so that goes with the dinging for the engine running!
