Stop start stopped working
Has anyone else had the stop start system stop working on their new XC90, mine no longer operates even though it is turned on in the Sensus system, it is not working in any drive mode, car is due its first 3 month check next week so will ask them to check it out then.

Stop start stopped working.
Isn't the work/doesn't work logic affected by the battery condition? i.e. Unless the battery charge is up to "normal" the car won't cut out.

The engine does not auto-stop
The engine does not auto-stop in the following cases: The car has not reached approx. 10 km/h(6 mph) after starting. After a number of repeated auto stops, speed must again exceed approx. 10 km/h(6 mph) before the next auto stop. The driver has unfastened the seatbelt. The capacity of the starter battery is below the minimum permissible level. The engine is not at normal operating temperature. The ambient temperature is under -5 °C or above approx. 30 °C. the windscreen's electric heating is activated. The environment in the passenger compartment deviates from the set values. the car is reversed. The starter battery's temperature is below or above the permitted limit values. The driver makes sweeping steering wheel movements. The road is very steep. The bonnet is opened. The gearbox is not at normal operating temperature. When driving at high altitudes when the engine has not reached operating temperature. The gear selector is in ± position The ABS system has been activated. In the event of heavy braking (even without the ABS system having been activated). Many starts during a short period of time have activated the starter motor's thermal protection. Applies to cars with diesel engines: The exhaust system's particulate filter is full. A trailer is connected electrically to the car’s electrical system. |

I am aware of all the above but none of them should be preventing the system working in my case, normal conditions and no low battery warnings (3 months old) stop start has not worked once in the last few weeks of motoring, it used to work in the same conditions I am driving in now.

Extreme hot weather, (I wish) I live in the north east of england, we dont have extreme hot weather here, it has averaged 19 degrees over the last week which is good for here but if a car cant operate at those temperatures it should not be in production. It has just stopped full stop not worked at all in the last few weeks. It used to be intermittent in comfort mode but always worked in economy mode which reduces aircon but does not work at all now.

I am afraid then that it looks like a trip to the dealer will be needed........

Just a thought but the battery on the previous model XC90 was notoriously feeble - you only had to have the radio on for an hour whilst cleaning the car for it to give you a battery low warning.
So, perhaps if you have a number of ancillary items running, such as aircon, radio, phone charger etc., one of the (very) many on-board computers has anticipated an unacceptable power drain on the battery if the stop/start system should be engaged, and is preventing it from working. |
