Auto electrician / Specialist to look at dodgy seat sensors Birmingham

If you want to have a go at fixing it yourself the first thing is to scan the car for fault codes in the Airbag module. Once you have the code(s) it should direct you to whats the source of the fault. The usual cause is loose or dirty connections under the seats often set when the seats are moved. Also be aware that disconnecting any of the airbag connections and then switching on the ignition will set the airbag light and set codes in the module. If you don't have a code reader there are a couple of options, the B800 Airbag code reader is a basic cheap unit to buy on ebay and will read the codes ok but just airbag codes. If you want something more useful that will read all modules on the car then invest in a Creator 310+ Code Reader for circa £50 on ebay or Amazon. The Creator will read all modules on the car and is very easy to use, sorted an airbag light I had which other software on my Laptop, INPA and BMW Scanner 1.4 couldn't clear, the Creator cleared it first go. Rare for the actual module to go bad unless the car has been in an accident which causes the module to be locked up and has to have the data file inside cleared of the crash data it has recorded. This involves using software to read the eeprom chip inside and using the software to clean the crash data out.
Appreciate the reply, seat got wet so I’m wondering if that could’ve done something. Will invest in that reader and come back to you 
Always handy to know what’s going on. All my wiring looked ok touch wood.

The air bag wiring is those with the yellow connector under the seats.
From your latest description of the fault relates to the passenger seat circuits, I would hazard a guess that the code reader will come up with a code for the seat occupancy sensor, if the buzzer sounds until you plug its belt in. The occupancy sensor mat in the seat squab must think someone is sat in it so the buzzer is demanding the belt to be buckled.

So as above invested in c10+ and it’s pretty bad ass after getting my head around it. So I read the codes, reset them and going to see which ones come back, as the air bag light has stayed off. The occupancy sensor does buzz on the passenger side still.
Will drive it around for a bit and see if any of the above codes come back.
Both seats had been removed to replace a wet carpet so fingers crossed.
