Golf 2.0L mk4 with an Intermittent misfiring in
I have a Jetta 2.0L MK4 and had this problem as well. I believe the engines and ignition system are similar or equivalent. The key word you stated is "damp" weather. So, in damp weather the surfaces of almost everything in the engine compartment has a microscopic coating of water on it. Also, almost every man-made material absorbs some water. So, in damp weather the plug wires and coil pack can have a microscopic film of water and/or will absorb some moisture in their insulating materials. Any micro cracks or internal carbon tracks in the insulation can offer a path of least resistance in this moist environment. This can cause the high voltage to find a partial short-circuit path or a complete short-circuit path to ground before reaching the plugs, hence causing misfiring. The heat of the engine will dry out the moisture and make the problem go away temporarily. So, to troubleshoot the problem do the following: At night and in the dark, and with the car engine just started in damp weather, look for arcing. If arcing is observed you found the problem! It not, let the heat of the engine dry out the ignition system and allow the engine to run smoothly. (Temporarily close the hood to hasten this process) Use a spray water bottle with ordinary tap water (not distilled water) to lightly spray the wires and coil pack so that you can look for arcing. DO NOT TOUCH THE CAR WHILE SPRAYING! Spray in an orderly manner to try to pinpoint the problem. It is possible that you may not see the arcing but the engine may misfire when sprayed. This usually finds an issue with a weaken insulation system. If not, I have seen on this same Jetta a weak coil pack output on 1 of 4 coil outputs causing an intermittent misfiring, more so in damp weather. In this case use an in-line neon plug tester to look at the neon "glow" on each plug wire to see if any of the coil outputs are weaker than the rest. I had to replace the coil pack in this instance and it resolved the problem. I hope this information helps!
How do I set the distributor timing on the golf mark1 fuel injection?
take out the spark plug neares the belt pulleys then turn crankshaft till the car is on compression stroke jut at top dead center stop it at top check to be certain on top after compression the number one plug tower on the distributor will be were the rotar is to be positioned with the distibutor case placed in the normal way it was befor it was removed rotar faceing the number one distributor wire closest to motor on top of distributor right clockwise 1342

Temperature sensor is common fault on gti, catalyst efficiency will more than likely require a new cat, not cheap fix

get one of those online manuals. You'll not have to wait for others to answer, or rely on mechanics and all. Plus i know a website that sells very cheap but very very good manuals online

How to clear a epc light from golf 5 fsi engine
If U don`t have VAGcom to read and erase the errors try first the brake switch if its ok (sometimes the brake lights remain turned on even if the brake pedal is released and this cause the epc light on).
If you see a engine speed decrease when epc turns on the error could be from admision *(air intake) pressure sensor . You can disconnect your battery minus*(ground) for 10 or more minutes to turn off the epc light but if you don`t resolve the problem epc will turn on again when U start the engine. My advice is to find a Diagnose cable and read the error to know exactly what is the problem
Temperature gauge is broken, needle is constantly on cold
Check the obvious first!! Check the wires to the sensor on the engine are clean and price up replacing the actual sensor as well. If it's running a fan belt it'll be spinning as soon as you start the engine so won't affect the engine. It's only the more modern belt-less electric ones that depend on a sensor to work.
On a car that old it could be as simple as the gauge on the dash has died. Price up a replacement set of second hand dashboard dials and swap them yourself. It's a fiddly job but not hard.
