Inaccurate speedo

[Pettsie]

I have not had my 350i for vey long and am suspicious about the speedo reading. If you were at 3500 rpm in 5th gear in your 350i, how fast do you think you would be going. Mine reads about 85 at that but everything on the M3 seemed to be going backwards!

Does anyones heater actually work?

What is the 'tap' for on the heater hose near the bulkhead?

Thanks...

Tap, as in drain type thing? Sounds like the mod I will be doing soon. Get rid of air locks as its the highest point in the system?
Or is it the on/off valve you mean for the heater, wire going to it?

Mine does 80 at 3000 revs.

Does the heater work - get real!

I think my 350I speedo is also about ten mph out on the low side with standard wheels diff etc, is there any way of adjusting them?

I have adjusted other speedos in the past - don't know about the one fitted to the wedge, but I would imagine it's possible. Look for a slider connected to the hair spring on the spindle

I've a 1986 350i and my heater does work. however i didn't think it did until I got hold of a copy of the owners handbook and realised the settings are not what you would think. for general heat and demisting turn the right wheel all the way to the right. For demisting the screen the right wheel needs to be in the centre and the blower on high.

Not really. Someone like speedy cables will recalibrate them for a fee though.
