Hi, My 200 tdi has suddenly become hard to start if it hasn't run for a while. If it has just run it fires up straight away. When starting it will crank over and over and over then catch and stop then catch again, run very lumpily then start running normally with a blip of the throttle. There is always white smoke on start up which clears as it heats up. Once running it is fine, there is plenty of power and I can't detect any issues. No hunting, surging etc etc. My plugs are only a few years old but I haven't taken them out to test on the bench. I'm getting 10v at each one My battery is at 12.5v Earth strap is fine (tested with jump cable from battery negative to chassis and also engine) Starter isn't sluggish and spins at normal speed New fuel filter fitted New leak off pipes between injectors fitted (but not pipe back to FIP) FIP was replaced in 2011 Injectors have had no love since I bought the car (100K +) so that is on the list to do. Today I took out the fuel filter housing bleed screw and unplugged the FIP stop solenoid wire and cranked the engine over while watching it on a video camera. There was no fuel coming out of the bleed hole despite plenty of cranking. I then replaced the solenoid wire and tried again and there was instantly a gush of fuel from the bleed hole. Now. I'm not the brightest sandwich in the tool box but I'm pretty sure the lift pump is manual so I think the FIP solenoid wire has no bearing on the lift pump and this was a coincidence. Which means that fuel is possibly leaking back from the filter back to the tank and I had to crank it a lot to prime the line again. Based on the symptoms and bits and bobs I've played with. What tests should I try and what should I be looking at next? Many thanks.
Last weekend I stripped down my wiper motor as it was making lots of nasty clunky noises. Spending most of my time on the West coast of Scotland I’m quite keen that the wipers are functioning properly as they’re in high demand! The drive gear in the motor was quite loose in the casing bush and the linkage also had play where it hooks onto the gear, I fixed this by swapping things into a different casing off another car and everything was nice and smooth with no play to speak of, greased it all up and reassembled. All working fine on testing. However I’ve subsequently found that on first use from cold the first wipe is now very slow and often jerks across the screen quite uncomfortably, once it’s run a few wipe cycles it’s better and after a few minutes it’s back to perfect (save the slight play in the wheelboxes but that’s a different issue). I do have concerns about the quality of the motor earth and am going to sort that tomorrow by adding a decent gauge return to the battery, however I wonder if this is an issue others have had and if there is a known solution? The system was carp when it was ‘designed’ in the early 70s and hasn’t changed significantly since so I’m not expecting miracles, just the basic reliability. My currrent thoughts are running to firstly the grease being under-specced for the temperature range, or the motor just being worn out. As far as I know it’s 25 years old and will have done plenty of work.
