I have just bought a 2005 Z4 and I very quickly encountered an issue with the steering where it loses it's fluidity and makes the wheel more difficult to move. I encountered this whilst driving with the hood down and the climate control on hot. I went on the internet to see whether this was a common occurance and actually found lots of threads titled "Z4 sticky steering" on various different sites. People having experienced the same problem, but surprisingly no references on this site.

From reading the threads I know in the US that there has been an acceptance with BMW dealers that there is an issue. Evidently it is because the ECU, which is attached to the steering column, is too sensitive to heat, unfortunately this sits just behind the heater vent to the right of your steering wheel. The only remedy is to change the Steering Column for a later model.

I phoned my local BMW dealer in Bournemouth and they had never come across this before ? Does anyone know of any UK precedence on this please ?

Love the car by the way but this is dertacting from the experience and I feel downright dangerous.

Many thanks

That model may have had a "Recall" notification ... Gonna have a quick look ...

Sorry, the only recall on the Z4 was for a dodgy Fuel Pump...

IMHO.. If the steering system has an ECU then it must have sensors too, get a workshop manual and hunt them down and firstly check conns and condition then maybe find a way of testing...

Just a thought mate.

      SLIPPING CLUTCH

      Hi Dave, I fitted one of the sensors on the rear but it has made no effect as the light is still there, I will fit the other sensor tomorrow and see how it goes then. You mention the disconnect the battery, is there any pattern to this ? is it both leads or just the negative lead? cheers Paneuro.

      105C thermostat replacement

      Not sure what engine your running but there should be a Temp sensor in the Hose from the Rad to the water pump then there should be a Temp sensor in the housing for the Thermostat Both are shown in realoem for the 3.5 V8 I thought the V8 was the only one with dual use sensor on the Thermostat housing but stand to be corrected Dave

      105C thermostat replacement

      I have checked realoem and it gives me no temperature sensor option , which is strange. Also what I did was to remove the map thermostat and disconnected the resistance heating that is inside the thermostat and replace it with a 88C from an x5. Nothing else has been changed. The strange thing is that it run like that for 3 weeks in August. When I start the car last week the temperature dial was going to max before dropping to normal value. And that happened only when cold. When warm the dial was showing the right temp. I also saw that the map for the thermostat was engaged when the car was running cold which made me think that there may be a connection between the thermostat dial and the map thermostat not being connected.
