Question about 1994 Volkswagen Golf
I have many problems so here goes
1. the car takes a very long time to heat up had the thermostat changed the fan works it just takes forever for it to go on.
2. the lights on the dash work when the feel like it
3. cant get the radio to go into safe mode nothing appears
4. oil light goes on and makes this beeping noise that makes me want to just crash the car around 2000 rpms then if i step on the gas it goes off
5. the engine light is on
cant pass emissions these are my readings im guessing its o2 sensor
ASM2525 TEST curb idle test
limit reading limit reading
HC ppm 66 192 fail 200 247 fail
CO% 0.37 3.61 fail 1.00 5.99 fail
NO ppm 505 15 pass
6. also the hose at the top of the rad feels like its only got air in it im not sure if its suppose to be filled with coolant or what?
any help would be greatly appreciated thank you
Let's start with air in the hose. When you changed the thermostat you have to bleed the system to remove this air. IF you don't the thermostat won't ever come on. The air pulsing in the hose IS NOT NORMAL. Do you know how to bleed the system??
The oil light. First check if the oil level in the car is good. If yes check the oil pressure. You need a gauge. Make sure to simulate the problem and test the pressure when the light comes on. If the pressure is good 2 options. First defective oil pressure switches very cheap to replace. sometimes you can even buy lower pressure ones that won't make the light come on. OR the oil grade is too thin. Try a 10w30 instead of 5 w30 thicker oil will cause less drop in hot oil pressures.
The cluster lights. Most probally a bad connection in the cluster. Losts of " A3 " body clusters were able to be repared but you need to do it right. It is printed board.
The radio. Check and find the radio fuse. Under the steering wheel a little to the left. If the radio fuses are good check for power and ground at the radio. If all is good radio needs to be replaced as the face probally got loose.
For the engine light have a garage pas a scanner cause it can be related to alot of things other than an O2 sensor. You'll save money by knowing what it is and not guessing.
