Since unfortunately having had my 156 written off a few weeks ago I have been enjoying driving around in my new 159 2.0 JTDM Sportwagon. That is until tonight when I noticed the coolant level was way below the minimum mark and water pooling on the engine undertray. The water/coolant appears to be slowly dripping from the front of the big black plastic housing that looks like it is bolted onto the front of the thermostat on the right hand side of the engine.
I currently can't get my iPad to upload the pictures I've taken but does anyone have any ideas as to what this part is? I'm currently slowly finding my way around this engine (my 156 was a 1.8 Ts petrol and seems tiny compared to this engine!)
Many thanks in advance
