Did you have the car on STAR after fitting the new SAM

I would for now just use the car for a bit and see if the warning goes away. it there was noting wrong in this respect then it could just be a programming thing
It will be the SBC pump charging the braking system
So nothing to worry about I guess?
Hi
I bought the SAM unit from eBay which had the same Part Number as my orginal unit. This has now resolved my battery convenience functions error. Also, all my interior consumables are working.
I have one more issue. Engine Management light is on and error P0403 is recorded. The car has no problem with the drive. What would be the cause?
Thanks for your help.
If you have an issue with the SAM unit, does it throw an error message? I have a similar issue I am looking to resolve with the battery convenience functions error.

All depends on what kind of running the car has had recently. Lots of short runs with heater, rear window, lights,wipers etc on followed by parking up for 72 hours and then starting from cold with the same ancilliaries on and it could be normal. The battery is 50% charged so the voltage drops for a few secs with all the current drawn for the starter and the warning trips.
By the time it has, the alternator has caught up, is steadily charging and all is well.
Just take it for a run or trickle charge it to top up the battery and it should be fine.
Alternatively the battery is faulty and not holding charge or you have a battery drain issue. The 3rd I doubt as with most of these, after 72 hours it would have been reluctant to start (dependant on what state the battery was in when you parked up). The 2nd is possible but again I'd imagine that after 72 hours parked, starting would be an issue so in this weather the 1st would be my initial diagnosis.
