Drove her to work yesterday and backed her in garage. This morning jump in her to come to work and the speedometer didn't work. I never heard anything pop and it worked perfectly yesterday.

Does anyone had this happen??
What to look for??
Troubleshooting???

Thanks,

I posted some info here not long ago on the speedo. It's in the forum, run a search there is a lot of info about the speedo available, common problem with the MKIII. Uses 3 cables, any one of them might be the problem, or it could be electrical. As I have not yet had a problem with mine I only read it briefly and reposted it here somewhere. Google it and you will find tons of info from other sites as well. Check this out maybe this will help

Some only use a two piece cable.

there elecronic on newer vehicles right? dont the just have ANOTHER sensor?

Sensor???? Where would it be???

My Dad has an MK3 that has been broken down at his house about as long as mine was. His Speedo just bounced but worked. Annoying to say the least.

Did my first AC evac and charge today. Went OK. My Ac is working. Should be interesting to see how long it lasts.

Cre, when I took off my compressor it had no oil. It was seized. Should I have assumed that the entire system would be dry or near dry of oil. I put about 4 ozs in the drier and the 4 in the compressor. I didn't want to go more in case there was a few ozs still in the condensor, lines and other parts of the system. Being that the compressor was bone dry should I have gone a full 10 ozs? My $9.99 AC compressor off ebay is working just fine and apparently not leaking.

Sight glass is not clear even after 3 cans of refrigerant. When the clutch disengages I see foam, when it reingages and is running I got a bubble or two about 180 psi on the high side and about 34 on the low side.

I did evacuate it down to -29psi and the vacume held fine for like an hour and a half before I went forward and charged it. What do you guys think?

What were you results? Should I have added more oil less?

Thanks

holy repeat post batman!

ah haha..

Yeah sorry about that but I was hoping to get an answer quick on the oil. No such luck yet.
