As a newcomer to this owners club and having owned an 2002 Vectra C 1.8 LS for about 7 relatively trouble free months (apart from a new water pump) , I am now experiencing an engine electronic system problem that has resulted in calls to the RAC twice in the last week. I wonder if any members have experienced similar problems (apologies if covered elsewhere in previous threads) that could perhaps offer some advice. The problems first started about 2weeks ago in the following chronological sequence:
Monday - Unable to start the car due to what appeared to be a flat battery after the car had stood overnight after being regularly driven previously. Started engine with jump leads from my other car, following all appropriate guidelines in the owner’s manual. Had battery checked, told was OK. (Green “eye” visible etc. voltage drop under start load acceptable, terminal voltage OK)
Thursday – Having driven for over 10 miles in the afternoon (and similar distance in the morning) , the car was parked with ignition off but lights on, waiting to pick my children up from school. The car would not start again with symptoms similar to flat battery again. RAC called who immediately identified a slightly loose connection on one of the battery terminals. After tightening both battery connections the engine started first time.
Friday – Again having driven the car to and from work, on the journey to collect the kids, my wife indicated left and then immediately right at a junction and as she was indicating the Engine Electronics control light briefly lit and then went off.
Monday – Driving in slow moving traffic, the alternator lamp, the engine electronics lamp and the ABS lamp all lit and stayed on. All the dash board dials registered zero (i.e. tachometer, speedometer, fuel gauge and temperature gauge). The car was driven for a further few miles but after stopping to drop one of the children at school, the engine would not start again!! Every time the ignition was tried, the three warning lights were lit. After several attempts (having left several minutes between each) the ignition was turned to position 2, the warning lights were lit and then went out. Once out, the car started first time OK. RAC attended again but was unable to interrogate the OBD as their diagnostic system could not read Vectra C’s. The car was taken to a Vauxhall main dealer who said there were no errors logged in the memory and therefore could not diagnose the problem.
Ever since that Friday, the car has now behaved identically each day. Every time I come to back it out of the drive in the mornings, the engine electronics control lamp and the ABS lamp light up briefly and then go off within about a minute of starting the car. On the journey to the schools, it occurs usually twice again and then throughout the rest of the day and often into the evening, nothing occurs until the following morning.
I have also noticed that the heated rear window will only work for a couple of minutes before the same warning lights come on, the heated rear window switches off and the lights go off again. This morning whilst trying to evaluate all the symptoms, I experienced the loss of all dashboard dial readings again, even though I was stationary in the drive.
Has any one experienced similar problems and if so what actions were necessary to rectify them? I have read elsewhere that it might be as a consequence of a faulty ECU, ABS bus connector, CIM failure or the Body Control Module but any advice or assistance on this problem would be gratefully received.
Sorry for the length of this posting but I have tried to include as much detail as possible.
