So basically bought car with oil sludge in the header tank, intermittent temp gauge so changed the temp sensor, replaced damaged dipstick and drove fine, no smoke etc. (was chucking a bit of oil out of dipstick before I replaced it)
Changed oil cooler and refitted a couple of vacuum hoses with damaged ends kind of thing and now I get intermittent thick smoke on idle, doesn't seem to clear by revving but passes for a bit.... Then comes back. Could be related to engine coolant temp from watching the coolant temp go up on vcds and it start chucking smoke out.
I'm not sure if it's more likely pcv building up pressure or if it's engine coolant building up pressure then leaking or the same but with oil. Smoke is white with a slight blue in it
Thanks (I've come from 2.0tfsi and tried searching)
