dunk1 Posted March 2, 2021 Report Share Posted March 2, 2021 Hi guys. My 04 330ci was working no issues, drove to a mates workshop parked up for an hour or so, came to leave and the key fob wont unlock or lock the car, put key in ignition and it turns on all the dash lights but the engine wont turn over, tried disconnecting the cars battery for 10 mins still the same, went and got the spare key and still the same Possible EWS problem ?

dunk1 Posted March 3, 2021 Author Report Share Posted March 3, 2021 Doing some checks i've found there is no power to the top half of the fuse box Link to comment Share on other sites More sharing options...
Schumacher Posted March 5, 2021 Report Share Posted March 5, 2021 Some of the fuses are switched live. Have you tested the battery and are the fuses ok? Could be a faulty GM5 module (below fuse box) or the antenna diversity amplifier (nearside C-pillar). Link to comment Share on other sites More sharing options...
dunk1 Posted March 5, 2021 Author Report Share Posted March 5, 2021 Thanks for the input. We've found the problem and done a temporary fix, a wire going to the Body control module had been cut through by a cable tie wearing through it, why there's a cable tie round it I don't know. Going to solder and shrink wrap it so fingers crossed it'll be sorted by Monday at the latest Link to comment Share on other sites More sharing options...
Schumacher Posted March 5, 2021 Report Share Posted March 5, 2021 Someone's obviously been in there before as BMW only use black fabric wrap. Hope you manage to fix the issue. Link to comment Share on other sites More sharing options...
