Monocle

I could be wrong but I think the sponge is just held in by the EGR. Honestly can't remember but definitely not anything to worry about. 

I bought it on a disk on eBay. No link unfortunately. Only about a fiver. Well worth it.

Hi @Coolissimo!

You are right to ask. It is a while since I did this but I know you have to remove the reservoir tank so at least that much of the system will need to be drained. I think I replaced the coolant at the same time hence the full drain. But, simple answer, just empty the reservoir and you should be fine!

Will try that next time. Don't fancy taking it off again for a good while!

Did you ever take off the exhaust manifold? I presume temperatures are high enough that the carbon build up should be nil and not worth doing???

Looks like a good way to go! But I don't have a blow torch or compressed air handy!

Hi both, apologies for the delay in a response. Firstly, as this was a pretty instant failure, the car just went back to normal performance. I don't think that it had been blowing more than a few miles. The smell hits you straight away.

Glad to hear the job went well. I've had to do it again since so I will update the guide with some additions and your comments.
