1998 E300 Turbo Diesel W210 - SRS Light Comes On When Very Hot Inside

[nhdoc]

Hi,

Last summer one day I noticed when I started the car the red SRS light on the cluster stayed on while I was driving. I remembered it being a particularly hot day and the car was parked in the sun. At the next shut-down the light went out after I restarted the car and it never happened again...until today. Same conditions, same light, same reset at the next shut down and restart once the interior had cooled. Is there one part prone to this type of failure or do I have to resort to having the SDS scan done at the stealer? Also, will the SRS system store the code even though the light has reset itself?

Thanks in advance!
