DME relays were/are a known failure point, especially for my old Porsche. Just though I would cover off another potential culprit. The relays are blue in colour and located by the DME. DME talks to quit a few components so keeping a close eye on the thing. Spent quite a bit of time today checking all the fuses (Got to love the front fuse box..) All fuses were good. My BIG concern is this thing sat for well over a year and owner reports it running when parked due to rear bags collapsed and pump not operational (Confirmed pump not working and main 40A fuse blows - Looking for a replacement so somewhere over that time something went off the rails. I guess its possible the regulator could have gone faulty over that time frame. Or that was another reason it was parked.
