i wonder if you have experienced this, i have a R52 with 120K miles on the clock. starting last week, during drive, there seems to be a short (fraction of a second) flashing of 1 or 2 of the warning lights, eng temp and gas gauges dropped to the lowest and return back to normal, speaker sound went mute for a fraction of second and come back on. as if the power was cut for a really short while and come back.

i should emphasize that the car still drivable and ignition still on after this. no interuption of the car engine.

i said it was seem to be a power cut but actually it did not, because i have my bluetooth connected with the factory stereo and it never got cut out during the "interuption". if there was an actual power cut, the bluetooth should be disconnected.

where do you think i should look into?

 

I'd start with having the battery and alternator tested.

 

Grounds, Battery, Relays and Ignition switch, Alternator, in that that order, are what I would chase. Easiest to Hardest, Cheap stuff, as best you can first.


Good Luck

 

thank you all. today further drive with A/C on, found the situation happened more frequent.. will it point to a finer area?

definately gonna check all thinks mentioned...

 

folks i have replaced the alternator with a new one. resetted the ECU. the problem still there.. any other places to look at? yeah seem like problem is worse with A/C on but less frequent without A/C.. any insight appreciated. cheers, r

 

which Relay to look at? thanks.

 

replaced all R1 R2 R3 R4 relays and the problem seem solved! sticky relay it is!

 

Glad that worked out.
