Have done a search because i seem to remember reading about the black lids not being very good and to replace them with blue ones, but cant seem to find any useful threads!
Anyway, i am losing coolant slowly, and having replaced the clips and some hoses where it was leaking, think there is some coming from the lid. I can hear it venting after i switch off the engine, and the bonnet has been wet where steam has sprayed out from the lid. Question is, is this requiring a new lid, and if so, is it a VW stealership only part, or will a G&S or ECP part be just as good?
If it is only VW, has anyone got a part no. and price, as the joker in the parts dept here is absolutely useless at finding stuff...?
Also, the heating just isnt getting hot at all, after losing a lot of water (expansion tank empty) it has never been right. I have run the car up to temp with lid off, bottom hose cold, then hot, water level going up in expansion tank etc, just not hot! The fan didnt seem to kick in either, even when i fast idled it (3k revs) for a few minutes. Is this the thermostat? I thought that if the bottom hose became hot, then it suggested the thermostat was working?!
Thanks
