no worries, also another thing worth doing is take out AA breakdown cover, its around £80 a year and covers for £500 and upto 5 claims. Its not much, but lets say you damaged your EGR its £350 brand new without fitting, therefore worth while having some cover.
I have taken it out, as just in case the head goes, or flywheel I can take it to local vat reg garage and get it repaired for a few hundred after the cover pays out. Worth bearing in mind!!
