Reminds me of years back when I was young and carefree and so were my mates.
Friend of mine drove his Honda Civic onto the beach for some romantic time with his girlfriend. It was well after midnight and pitch dark. Time passed as they were obviously having fun, then suddenly he heard splashing on the underside of the car. Turns out the tide was coming in so he started the car to get out. Problem was sand was saturated from the sea and he just got stuck and couldn't move.
They obviously got out, but by the time he knew where he was, waves were half way up the car. He got someone with a teleporter to pull it in off the beach. I remember him asking me to have a look at it as it wouldn't start ( not surprising)
At the time me and my mates thought it was the funniest thing ever and just couldn't stop laughing at what had happened.
Remember looking into the car and it was full to the sills with sea water, sand, sea weed and possibly shells and jelly fish . I drained the oil from engine and box and dried out the distributor. I removed the ECU which had already begun to corrode, replaced it and up it fired!
He drove the car for a further 4 years and all that ever went in that time was the alternator, then again it was a Honda Civic not a BM Troubleyou
