  1. Either way it needs to be pulled out... There's a how to or something on here somewhere. Maybe in the gearbox thread? Have a search
  2. Ok, hmmm. I like tricky ones like this. it's either a fuelling issue or ignition fault (or both but unlikely). Let's eliminate what it won't be. ECU- I've never seen one fail. Plus you'd get no data access or a definite ECU fault code (they have built in self diagnostics). Not O2 sensor. Not knock sensor- only effective once hot and running. Throttle body (TPS). Would still start and run albeit in limp mode. Charcoal valve. Would run a bit lean. Injectors. They're tough usually. So bearing in mind that the car was parked and standing in storage for ages without being prepped, it's most likely a moisture related issue (or rodent nibbling- which I have seen a couple of times!). Most likely: Fuel pump fuel control relay Fuel filter (for these 3, try pulling off the fuel supply hose to the fuel rail- and under the rear seat connecting 12v to the pump supply line and see if you get a decent fuel flow. Handy to have an assistant to stop fuel going everywhere). ignition coil or module or whatever you call it hall sender (unlikely, but they do go very rarely- for these two pull off the plug leads and check for sparks on each plug- pull plugs out, rest them on an earthed point for circuit continuity-again, helper handy to turn ign key). Possible but unlikely: MAP sensor- you'd get a code plus engine should still start, but run rough. EGR valve stuck open. Would cough a lot and run very rich. But run with black plugs as a result. Actually it might be this on second thoughts. The valve central shaft may have corroded a bit making it sticky because it was in storage. Condensation and all that. Not sure which type is fitted on this engine. Could try disconnecting vacuum or power (you'll get a code but can clear it later), or unboltimg it and making up a simple blanking plate across the gas feed. Relays. Er, no easy way of checking other than sticking a meter on the outputs. And if you can do that, you may as well unplug them and examine on the kitchen table. But the main power relay that runs half the engine is known to go iffy, as is the fuel pump relay. All going on behind the fuse panel under the steering. Ignition switch. They can play up. But you'd see headlights not working at all. When on. End of lecture.
  3. 100% pedal box. Especially if difficult to select 1st when running, stationary and cold. Every time you shift without fully disengaging the clutch, you damage the syncros... you need to sort it asap or you'll lunch the box too. Once sorted, flush, then renew the gearbox oil. Loads of crud will come out. SDI has a cable clutch. It works or snaps.
  4. Yes, can be welded (properly). I have a pic somewhere of where it breaks.
  5. That's a big antenna on the roof! Must be a miniature model... My 3 SDIs are all boring colours.
  6. That is gorgeous! Mmmm. Such style 👍🏻😀 And I've never ever seen an orange lupo. Ever. That's a first for me. Is it factory orange ir did someone respray it? Wow! Lots more pics of the orange lupo please. And inside. It might be a rarity (worth something). Just realised it's an Arosa! D'uh... 🙄
  7. If engine code AUC, then it's at the back, next to the flywheel, right down the bottom, just above the sump. Follow the cables. Crank sensors are usually located in the crank plane, at right angles to the piston travel, on the tangent. Any (modern) engine with an ECU will always have a crank sensor And yes most likely. I like Karmann Ghias. Pic please!
  8. Yes and yes I do hope it's not the rings, meaning it's just a sensor. Easier fix.
  9. You could use the gear shifter from a polo or another tdi lupo... clutch is hydraulic though. https://workshop-manuals.com/volkswagen/polo-mk3/power_transmission/5-speed_manual_gearbox_085/technical_data/gearbox_identification/
  10. To know what you need, i use these: https://volkswagen.7zap.com/en/rdw/ https://nemigaparts.com/cat_spares/etka/volkswagen/ http://www.oemepc.com/vw/main_group/markt/RDW/modell/LU/year/2005/drive_standart/441/hauptgruppen/1234567890/lang/e then just buy from wherever you can get them.
  11. Nope. None of the above. You should have left absolutely everything alone. What has happened is that condensation (acidic water) from burnt fuel exhaust has stayed inside the exhaust and combustion system (in the cylinder head). When you start and run a car for storage you have to run it till it's roasting hot, rev it to 4 or 5k, hold it there then while revving it, kill the ignition and let it run down dead. That will help flush out the waste gases and run clean air through. The condensation has caused the rings to stick and depending on type, reacted electrolytically (battery effect, dissimilar metals) with the piston grooves. two solutions, take it on a long motirway run and hope that the stuck rings release. Pull the engine to bits and unstick the rings manually. That's the reason you're getting lots of codes. ECU can't understand that fault... oh and welcome to CL!
  12. Yeah. BMW learnt a very big lesson there (as did the whole car industry). Was in all the auto news as well as general press. Some newish beemer was driving along der autobahn at about 160kph. Electric power steering motor stops. No steering- locks up solid. Autobahn curves slightly. Not enough time to react. Dead. Recall. Happened a few times apparently. In any safety critical system, where control is required, there MUST be a redundant system. In cars there is never any redundant system (too expensive) with the exception of seat belts and air bags, dual circuit brakes and handbrake.
  13. Hey @iwcham1979, you might be able to use a standard lupo hydraulic steering rack with a polo pump...? The electric power steering column system looks like a complete self controlled system so you could try it? @RAB, is the 3L quite heavy for parking? I haven't driven a post 1991 car without PAS... Old mk2 golfs are no fun unless you've just left the gym. That drawing looks like there's a worm gearbox on the steering column shaft. At least it looks like it, as the motor axis is perpendicular to the column. I imagine that if that motor stops dead, the steering must lock up (just like leccy windows).
