Hi try cleaning the connector to the heater element, unfortunately as far as I am aware you can't change the element as they don't do it as a separate part you have to buy the whole tank in which case try Nirrol in Barking they might have one.

Thanks steve 

I assume that is the connection next to the tank. 

And I bet the tank isnt cheap if I need to replace the tank 

Hi guys.

My EML came on today randomly.

i have ran VCDS on it and have got the following code and i am just want to make sure that what i have worked out is correct and to find out what is the next/best way to proceed with this - as in DIY fox or if its better to go into a garage?

the data is as follows:

(i can provide full scan details if required)

from what i have found it sounds like my adblue heater No. 1 has failed.  

the help im needing with is:

1. would i be correct in saying that this is inside the tank, if so do i need to remove tank etc to change it?

2. has any one got any help or advice in doing this DIY style?

thanks in advance.
