MDifficult said: When we arrived at Calais it was... chaos. We arrived at 2pm for our 3:30 train and basically sat in one long queue until we eventually made it on at nearly 6pm. 4 hours of queuing in 34 degree heat. Cars were overheating, breaking down, people losing their tempers, all over the shop.Small world! I got stuck in the same chaos with a couple of mates on our way back from a road trip in my E92 M3- we actually ended up queuing next to your friend in the E46 M3 who we had a very pleasant chat with, and the Aventador in your group followed us through border control- don't think I s

The MINI decided to throw me for a bit of a loop this weekend... Ever since we've owned it, every once in a while it would say that a brake light bulb was out on the drivers side, but it would then go away again. However, it started doing it more often and a bit of internet research said it was either a bulb or a common problem with the earth pin on the tail light connector going bad. No problem - Saturday morning I open up the little access panel in the boot with a new bulb and my can of contact cleaner at the ready and... oh.. interesting.. some enterprising 'mechanic' had run a red wire from one of the tracks on the bulb holder directly to the where the body earth attaches to the chassis, and the retaining slider for the connector was broken. Clearly.. someone had been here before. I removed the bodgery (which explains the intermittent nature of the issue)...Inspecting the connector, it was easy to see why they'd had to do the bodge, the earth pin was completely mullered and, checking the bulb holder... the earth pin was completely gone! Again, internet suggests this is a very common issue and the solution (clearly) is a new connector and a new bulb holder. Nipped to BMW for both, cut off the dead connector, crimped a new terminal onto the earth wire, re-pinned everything, connected everything up and...Nope. Problem. Lights fine, brake lights fine, indicators fine but every time I went for reverse... fault. I changed the bulbs. Nope. Okay, must be my wiring so I took the connector apart, re-did everything and... nope. Same issue. At this point, my friendly neighbourhood MINI mechanic (lives a few doors down) kindly stopped by and we pondered for a while. Out came the multimeter (these things are so much easier with two) and we re-checked all my twice-done wiring. It was perfect. A 2 minute job that should have been a bulb and a squirt of contact cleaner had descended into this... In the end, in a moment of inspiration, we decided to check if the bulb holder on th
