Here's that disconnected pipe:



Anyone know what it is?

I'm pretty sure they all have that mate. For what reason i do not know!

mines got the same blanking device...
thats not ur problem

[Blazing Storm]

Weird how they all have that. Learn something new everyday. Thanks for telling me. Wonder what it's for!

I think its a left over from the earlier days of the Golf when they were fitted with an economy meter. ie, you could moniter how much gas or power you were using.
It would have been connected to what is essentially a manifold pressure guage. Turbo or supercharged cars would have this connected to a boost pressure guage.

Cool, well that's another thing learnt.

Could someone tell me if I bought new clocks is there anyway of changing the mileage to what my current ones say now?

Peel, which pipe did you find disconnected on yours?

How do you check that the oil temp sender is working?

With the underdash off I can see that everything is connected to the clocks. I've looked around the engine bay and can't see any disconnected pipes.

Just a suggestion but the MFA didnt work on my 8v for ages until I found out that the car had the incorrect battery fitted, chnaged it for a new one and hey presto!

[Blazing Storm]

Really? I think it's the right one but I'll check tomorrow. Don't really see why it should make a difference though. Maybe resetting the MFA worked for you when you disconnected the battery.

I find it strange that the ambient temp is being shown on the MFA but nothing else on it works correctly.

If anyone could answer the other questions from my last post that would be great.

Yeah as far as Im aware the MFA isnt high on the electrical systems list of priorities so if the battery is underpowered or buggered then it wont work apparently. Id had the old battery on and off a few times to do work on the car so it cant have been re-set. As for your other questions Im unsure bud
