Hi all,

Have a w209 2003 and get coolant visit workshop up on the dash when driving in town, when air con is turned on the fan came on after being pushed along for a second , have now sat in the car wiped the codes and have tried it with the aircon off and let it get up to temp the fan kicks in for about 20 seconds comes off again and then about 5 mins later kicks in again. what do you reckon the problem could be? Warning light has just come on as the fan kicked in, have tried aircon again now and no fan this time


Thanks in advance

Just an update to help anybody else who had our problem, we purchased a used fan on ebay after diagnosing our module had failed, the used one stuck on full boar all the time due to another faulty module, therefore i call many motor factors that i usually use they all said if i wanted a fan with the module it was dealer only, mercedes said somewhere in the region of £410 plus vat so i did some digging online and found that mercedes a2035000293kz crossed over to nrf 47293 and various other makes i purchased a nrf 47293 from bestpartstore.co.uk which is german based and we fitted it last night and it works fine although the wattage of the motor is lower than the original, just a side note about bestpartstore.co.uk they say ready to be dispatched in 24hrs it took them about 4 days incl weekend to dispatch but i got it and couldnt reccomend them highly enough

Hope it helps at least 1 person cheers charlie
