This morning I checked over a second hand replacement EGR valve assembly, which appears to be coolant leak free.
I also noted a potential coolant leak point between the EGR cooler and the coolant passages in the EGR valve itself. The gasket between the 2 components is an elastomer coated steel shim type, and looking at this gasket it appears that the bond between the steel and elastomer deteriorates.
This could well be the issue with my EGR cooler, so it's a good job I had the foresight to order a replacement gasket.
I was only planning on fitting the second hand cooler, as my EGR valve is know to work.
However my plans to install the replacement cooler were scuppered, when Mrs Nodge said her VW has started spluttering after putting £40 of petrol in the tank. I replied it will splutter, your Eos is a diesel.
So I spent the rest of the afternoon draining 30 litres of petrol diesel mix from the tank, before refilling with fresh diesel and 500ml of stroke oil for good measure.
Thankfully it seems to run ok, so hopefully the weather will be ok for me to change the EGR cooler tomorrow instead.
