On Sunday I took part in a BMW club social drive and subjected the old girl to 4 hours of driving in 40 degree weather, I have the 4 window air conditioning option, to say it was hot would be an understatement.
The car was fine all morning but after lunch the idle speed would not drop below about 1900 rpm which made the two hour drive home a bit of a chore.
The car runs an after market ecu( Haltec PS 2000) and this has been no problem for the last year or so and always ticked over at about 750 rpm, occasionally it would sit at 1200 ish but a blip on the throttle would always bring it back down, but this time it sat steadfastly at 1900 or so, I thought possibly it might be a ecu fault but having spoken to Haltec they think not, any thoughts?
Cheers. John
Also given this problem would I be best advised to change the oil/ coolant after two plus hours of driving?
