Welcome to JA. My name is***** am a fully qualified vehicle technician with over thirty years in the trade. I will be happy to assist you today. Hopefully we can get this resolved quickly.
You will receive an offer of a phone call by the system, this only needs to be accepted if you wish to speak to me, I can otherwise continue to answer your questions via the thread.
There are a few reasons that the beeping may occur, this may be due to a seat belt not fitted or possible a speed warning which has been set on the dash at a lower speed than you are traveling.
The first point would be to check that the doors are all closing fully and that the interior lamp is operating correctly, this will eliminate the possibility of a faulty door switch.
It will depend on when the beeping occurs, but this may be a warning which could be accompanied by a symbol on the dash. Checking the dash warning signs against the owners handbook may highlight the cause of the beeping.
If this was purchased from a dealer then contacting the dealer who sold the vehicle would be the next move.
If this was a private sale, then a quick call to the seller, who should know the car may highlight a setting which can be altered.
I hope this answers your question but I want you to be 100% happy with the answer so do please feel free to ask any further details by replying to this thread.
