It was definitely the earth issue. All fixed now. Slightly bodged until I get the proper 50-10 cable lugs. Apparently they are like rocking horse ****.
It’s definitely the earth issue.
The gauges only go up if I turn the headlights on. Haha. They then drop to normal when the lights are off.
Just wont drive in the dark.
Thankyou all. I’ll investigate further.
Morning team.
Changed the top hose on my 300tdi yesterday. Very straight forward. Didn’t do a bleed on the system though. Ran it with heater on after the hose change then checked coolant level after it had cooled and topped it up.
Drove this morning and was overheating and the fuel gauge went up as well. Help.
