The SRS light indicates a problem with the safety restraint system which covers the steering wheel, passenger airbag, the seat side airbags and the pre-tensioners in the seatbelt reels at the bottom of the B pillars.
The common faults are the connectors under the seats and the rotary coupler behind the steering wheel.
When the light is on the SRS is disabled and is also a MOT fail.
check the connects under the front seats , is the usual problem , may have to take them apart give them a clean out ,
Spray them with electrical contact cleaner (available from places such as Maplin and RS components). Unplug and replug a couple of times helps.
most people just replace them with push fit connectors .
Speak for yourself Andy, thankfully most people clean them.
unless the brake pedal is juddering when u brake hard or at low speeds in which case it is a sensors or reluctor ring gone.
um, this is nothing to do with SRS, it's the ABS system.
and as gnu says disconnect the battery and leave for 20 or 30 minutes before fiddling as airbags tend not to like shorts .
The official line from MG Rover was to disconnect the battery for TEN minutes.
Personally I ensure that the ignition has been off for several hours.
