mk2

Ok, here we go... (I'm assuming good head gasket, normal fuel mixture, ok brakes, ok cat and normal ign timing. is there coolant in the system? does the water pump run ok and circulate coolant? does the thermostat open and keep the temp gauge at 90 without moving once warmed up and driving normally? Is the right thermostat fitted... do the fan(s) work? does the interior heating work? does the coolant level stay constant (no leak or crack somewhere)? does coolant circulate through the radiator (can you feel warm fluid leaving the rad through the hose, when engine is hot?)

Details?

Is that what the stuff is? Interesting. So Mr. Chemist, how does it work? Does it just coat everything or react with oil or CO2...?

Yeah I know. Heard the same. But where to go definitive... I can see me pulling box after box to pieces, probably ruining at least one or other till I find the right cogs. Won't go that way. No-one I know in Germany is willing to pull a 3L box to bits for me for cogs as they're worth too much complete!

There's typically an AC sticker on the panel next to the bonnet (hood) lock, just above the radiator. It tells you the system capacity 750g type of R and +50 or whatever amount of oil in grams to add.

Loosen it off more. If it was the pedal box, the biting point is almost on the floor. Or it might just be worn out...

AUG or AWY, but from an 020 box. I'm not sure if the shafts are right though.

Systems about the same size as mk4 golf, so I'd say about the same. 750g 134a. 50-75g of oil from memory. Vac it all out first for at least an hour to get any moisture to boil off. Whoever does it will see all the gauges anyway, so it'll be easy to tell when it's close to the limit.

Wiring for sure. You could probe all the ecu pins and see which one goes high/low while cranking. Diagram much easier. Sounds like more than one relay or control wire (to relay).

Yeah. So it looks like the only option is the fifth gear set and synchro from a 3L box. In this country... rocking horse poo. Unless I can find which mk2 golf had the same cogs.... anyone? Just got back from another 200 mile jaunt. Yeah, definitely needs to rev lower at 80 on the motorway.

Hey and you have the matching bucket. Gotta keep the car running now!

With ABS and tow bar! Shame it's a pre £30 tax car. Looks good, but no inside pics.

I don't think it'll work, but hey worth a try. Pull the head off. By the end of Sunday you could have it runnig again

Yeah, i have an SDI 1.7 (1.9) engine on a crate somewhere. Can measure it. Which bits do you need to know. Pic would be easiest.... Either I have it completely wrong or the part numbering system doesn't work! Ok, so the lupo sdi is the exact same lump as the 1.9, and comes as standard with the 085 FFV box variant (in the lupo). The engine is slightly angled backwards by I'd guess maybe 10 degrees. The 1.4 tdi uses an 02 something (as I understand which is to fit engines mounted at a different angle -I think). 1.9 TDI engines have bigger boxes for the increased torque, which I don't think fit the lupo without messing with cv joints and halfshafts and other stuff I'd imagine. I don't know what internals cross over. So where am I at? Have I got it all wrong?

Just had a thought @RAB... The 3L has completely different hub carriers and front suspension setup. Never worked on one, but from drawings they are 'odd'. I mean what's going on with those front wheel bearings?!
