Just wondered if anyone can help me with some advice. Completed a service on my A3 1.6 2004 last Sunday and had mayo on the filler cap and in few pipes. Now one of the pipes had been torn by Audi on the last service and I had only just noticed this - had been tapped up.
I was hoping as air and moisture would have been coming through this this was the cause as my water level is still where it has been for along time.
I have replaced the torn pipe and after a 120 mile trip doing 80/85 on Sat I still have a new build up of mayo. Thought this would have evaporated any moisture.
Now the oil still needs topping up from the service.
Can anyone give me a list of issues that might be causing this - I want to check all the cheaper ones first before a head gasket gets replaced.
