  1. Right, where to start with this... Having now reached a dizzying 1000 miles in my new Lupo I'm getting to grips with it's niggles and minor faults, but there's one persistent issue that really irks me... When accelerating hard in 4th and 5th gear (Around 3K RPM or above and between 40-70mph) I tend to get a heavy pulsing/judder/vibration feeling through both the steering wheel and the pedals. Most of the time this isn't an issue as I poodle the car round at sub 2k engine speeds, but it's something I'd like to get to the bottom of none the less! So far I've had all four wheels balanced and also had the car's alignment set up with a hunter 4-wheel alignment machine. This was actually carried out by the chaps who work on my Mazda (As a bit of a favour because we're friends ) they're a sportscar specialist and I have the printouts and saw the wheel balancing happening so I know this was done properly! You guessed it, no improvement At this stage my thoughts have turned to engine/gearbox mounts or possibly a flywheel issue *Crosses fingers for not flywheel* My question is simple... 1. Does anyone have any thoughts/musings/advice as to where I should be looking and as to what this issue might be? 2. Is my car (SDI) fitted with a dual mass flywheel? I'm assuming the answer to this is yes on the basis there seem to be several 'Single Mass' conversion kits available online, like this...https://www.dmrclutch.co.uk/products/dmr6008-dual-mass-replacement-flywheel-clutch-kit-75.html and another...http://www.eurocarparts.com/solid-flywheel-conversion-kit It's also worth mentioning that despite finding multiple 'Solid Conversion' kits online if there is an original style 'Dual Mass' available I can't find it so I'm assuming this is a part I'd need to go to VW for? Thanks in advance for any help or advice chaps. FWIW the car's so old/cheap that I may well not bother chasing this down but my inner meddler means that I can't stop trying to think of ways to get round or explain this issue.
  2. I've long loved my lupo. A couple of weeks back i was thinking about how its never had any problems, i've only ever repaired a handful of stupid little problems! Its done just over 100,000 miles, its a 1.4 Lupo E. Suddenly bam! Upon driving to work the car started juddering madly, i immediately started to blame the clutch but then i noticed the speedo was fluctuating all over the place, randomly alongside the juddering. The revs stayed steady, which seemed very strange. Taking the car out of gear i rolled to a stop, it started to judder again as i pulled away, and does now, more noticeably with lower revs. The clutch is fairly new, we tested it and it stalled the engine with the handbrake test really effectively. The bite point is normal too. My car has always had a little oil around the leftmost spark plug. I always thought this was from where i spilt a little oil around when topping up. A week ago i changed the oil and filter and cleaned it up. When the car starting this juddering i had a look under the bonnet and found this was actually a leak. I thought this could explain the juddering, the engine cylinder misfiring. I changed the spark plugs over, they were well past their sell by date, black and the leftmost one was oily. I brought some new ones and upon firing the engine up, loads of black smoke which cleared very quickly. The car was absolutely fine for a week! It answered my questions about the juddering and felt more powerful and efficient than ever, the speedo ran totally as normal too. However yesterday when driving home the juddering returned. Some oil has leaked too around the first spark plug and must be misfiring again. It now normally starts after a few minutes of driving. I'm going to take it to work for a compression as soon as i can. Can anyone shed any light on the source of this leak? Piston rings? Rocker gasket? Valve washers? Its whats causing this leak i'm sure, changing the spark plugs just brought me some time! Thanks everyone, i appreciate it.
  3. my lupo judders when braking, i can feel it through the brake pedal. i have had new front disks fitted which solved the problem. but 6 months down the line it's started again. any ideas? ta.
