Returning home for christmas Leeds to Bournemouth 270 miles. 100 miles in tyre pressure warning lights came on stopped at three consecutive motorway services and none of the air pumps were working. Then came off the motorway and 4th services air pump not working any way continue on and right front decides to give up the ghost on the A43 outside banbury halfway into journey. Manage to pull into another garage and ironically the air pump is working there but tyre has decided to cave in and tear on the side wall. 2hrs45mins waiting for the RAC in 1.5 degrees but had heated seats on and stereo. 1hr trip on the back of a lorry then once I`m dropped of in swindon battery is flat and once i get it started the thing wont move on the icy car park. The joys of owning a Z4. Anyway an early start tommorow to try and source a runflat front tyre and a mobile fitter and maybe a shovel to dig myself out. Lets hope tommorow is a better day!
