Similar issues regarding rear windscreen wiper and washer turning on intermittently, and drips of rusty water running out. I removed the tailgate trim, which is held on by two screws with star shaped heads underneath the emergency triangle storage box, and also by press in clips, which pull out fairly easily. The electrical connector and the hose clip are easily removed. I removed the base plate for the wiper motor assembly and washer spigot (very small star bits). It was full of rusty sludge. I cleaned it up and also cleaned the washer nozzles, using fine brushes. I reassembled it. On test, it leaked. I dismantled and re-evaluated.The washer fluid hose connects to a plastic spigot attached to the base plate, which in turn connects to the metal spigot that feeds the washer jets at the base of the wiper arm. When pressure builds up behind the nozzles, due to fouling, the plastic rather than the metal gives way and stretches slightly. Then the pressure of normal operation squeezes some washer fluid between the central spigot and its connector. I wrapped the metal spigot with a turn and a half of self amalgamating rubber tape and reassembled. The leak has stopped. The washer operates normally. The wiper operates normally, switches on and off when operated and stops at the correct point. Note that I would have preferred to work on the unit at the bench but the spline connector for the wiper base has rusted in. In my view it is a bad design to run water through the middle of an electromechanical device using press on fittings rather than securing the fluid tubing with pressure resistant connectors. The design is worse because it mates plastic and metal.

Welcome Michael and thanks for joining. It’s great that you want to keep a nice car in nice condition. For me, the first requirement would be - what not to use? - and that would be a pressure washer. I’ve seen too much lacquer degrading through using that method. Bucket, sponge and a hose pipe is my method, using a quality wax shampoo. Keep the car well polished (after cleaning) and in case it helps, I’ve always used Autoglym resin polish. Tried many others but always returned to that. Mobile cleaning kit?? Any degree of ‘spot cleaning’ when the car is in use, is likely to lead to lacquer scratching. If it were mine, I would simply carry a bottle of water and gently wash off any bird poo before giving it a good wash once home. I also use Autoglym glass polish, and their tyre dressing, together with interior cleaner as necessary. No connection with the company. Hope some of this helps, Kind regards, Gareth.

Cheers Steve for your reply, I can well imagine it’s pretty useless, because a, of the things you may need a double ended t30 bit and b, where would you use it because it’s about 10” long long ! regards Adder

**update** Replaced the high pressure fuel pump and seems to have fixed the issue. Only had the car with a new pump fitted for a day and so far so good
