Re: faulty fan on 93 golf gti
OK - I thought it would be but I had to ask! I'd guess the coolant temperature sensor is acting up, or its connector is dirty. I don't suppose there an an on-board diagnostic system on that year, is there? If there is, that's the route to go.
If not, you could try disconnecting the plug from the temp sensor and see what effect that has. If the fan doesn't act up, then it could be the temp sensor at fault. Without the OBD system it is a guessing game though, and the bank usually wins.
Let me know what you find. Cheers, D.

you might be able to reprogram the key, but you can only do this if you have two keys, what you need to do is put one key in the ignition turn the ignition on ( not over ) put the key that needs reprogramming into the drivers door and lock the vehicle with the key not the button, wait 10 seconds, remove the key, then press the unlock on the fobb, turn ignition off, remove key from ignition, put in the key that you just unlocked the car with and turn ignition do not turn over, turn off ignition,remove key wait 10 seconds, then put key back in then you should be able to turn it over as normal, if that does not work you will have to take key to be reprogramed at the main dealer...hope this helps
If as you say....Nothing is happening at all when you turn the
key, you appear to have one of two problems. A faulty starter
motor--or--- A faulty ignition switch. If you can tap the starter motor
while another person keeps the key turned to the start position, and
the engine now starts you now know it is a starter problem. When doing
this PLEASEMAKE SURE THEVEHICLE IS OUT OF GEAR.
If it should start up, or even engage the starter motor while IN GEAR, serious injuries could happen, and I do not mean to your car.
fuel relay could be faulty. i think its number 30 or 167 in the fuse box under the driver side steering. it could also be the fuel pump or connector on the fuel pump under the black metal plate under your trunk carpet. you could try manually throwing in fuel into the intake to make sure its not your car's ecu or ignition system. if it starts and stays running it could be what took me a few months to discover after i had intermittent problems. there a small vacuum hose from the fifth injector on a 1997 mk3 gti (4 cylinder) that connects to the injector rail. i think its some kind of activation for the electronic injectors. my pipe was broken and i just cut it and my car hasnt been better since! i know this is an old question but i hope it helps someone out there!
judging by the amount of km it has done i would say the rpm drive is faulty, this measures the amount of rotation in the camshaft and shows the "revolutions per minute". when this goes faulty it stops the read out on the dial, so you want to be looking for a device that measures the speed that the engine is turning, if you have, replace it and it should solve the problem
