Got my egr removal ki, spare bolts the lot. Had read a lot on this forum that the Allen bolts can be an issue. Fro two days I soaked them in wd40 . This weekend went for the troublesome bolts, nice and easy, top one released no issue, bottom one stripped the inside head. Bollocks. Luckily I tried these bolts first. Reattached the top bolts and ordered easy out kit from the Internet. Will try again next weekend.
