need your opinions if possible. I have a Mk2 2005 focus with 38000 on the clock. Never had any problems in the past. Is always serviced and well looked after.
Last week for first time i had problems. (on Good Friday) Had been out for the day and my Ignition light came on. Took it to quickfit for battery test and alternator test and was told it was low power. (the chap seemed to know quite a bit)
Took it down to the ford garage in altrincham and they were no help. No one available for advice. Anyways went back to the car park to drive home and got no power. All the lights were flicking on an off on the way to the garage.
anyways, the guys at ford didnt help me so the recovery guy came and booted the battery. Got 3/4 way home and it died again. Booked in next day in local garage and they replaced the alternator for 371.00. (not happy but had to accept it)
the car ran ok for 3 days then took it for drive down motorway (approx 40 miles) On way home my ENgine management light came on. Just out of interest i had bought a diagnostic cable and software when it went wrong earlier in the week. I got home and connected it up and the following were logged.
P0523 Engine Oil Pressure Sensor/ Switch Circuit High Input
P0620 Generate Control Circuit
P2503 Charging System Voltage Low
I didnt want to cause any more problems so didnt drive it over the weekend.
today took it back to the garage (the engine management light was on every time i turn the car on over the weekend but today it was off)
I showed the guy at the garage the printoff from the diagnotic software i used(called Formidable 2.03) and as expected he just said "leave it with us"
i got a phone call mid afternoon to say my car was ready. have picked it up and been charged another 40 +vat
speaking to the guy i asked about the log that i had found and he told me that his machine didnt show anything up other than error codes relating to low voltage
The invoice said the folliowing
"Check engine management light activation - connect to Bosch KTS 670 diagnostics and check engine management system. Note error codes relating to low voltage and earse. System Requiring 40 cycles for system reset."
i asked if it was related to new alternator problems as have read that new alternators can provide to much power which can trigger other issues.
he said the faults could have occured in the past and just decided to "show up" This i'm not convinced about! Ive never had any problems at all in the past.
Does this sound correct?? Im a pc engineer and when i diagnose computer problems the first thing i do is check the fault logs, repair the problem, check and empty the fault logs and see how the system runs.
i just cant believe the two problems are not related.
any opinions/ comments welcome
