Analogue Speedo & Fuel Gauge Issues

[Big_amos]

Hi Everyone,

I’m experiencing an odd issue with my analogue Speedo (frequent) and my fuel gauge (occasionally).

Analogue Speedo is massively over reading and often is stuck showing speed when stationary. Fuel gauge also suggested I have a 200ltr tank.

Can anyone offer any thoughts on the cause?

I have just had the engine out to replace air con pipe, IMS, clutch etc - could it be linked? It’s been fine up to then.

Pictures attached.

Many thanks. Alan.

has you car been smoking ....



since it's both, worth getting a PIWIS system test to identify an system issue
faulty cluster ?

I am currently having the same issue with my fuel gauge, but I haven't investigated it yet.

It’s certainly an interesting one. I may be having someone take a look today as I’m working near a classic car garage, I’ll post any updates I get on what it may be.

Maybe an earth wire problem for multiple gauges to go funny.
