So on my L251 I saw some cheap fuel and stopped to fill up, as my fuel gauge was reading just above half. The car wouldn’t take more than 2 litres of fuel. So I had a poke around to see what the problem might be.
The gauge doesn’t return to zero when the ignition is switched off. When manually returning the needle to zero and switching the ignition on, it climbs very slowly and eventually makes it to the halfway point again. The same when I push the needle to full - it drops slowly and eventually evens out at just above halfway.
Playing around with the instrument cluster to diagnose the fuel gauge problem, I noticed the back of the cluster behind the gauge was noticeably warm, so I’m guessing the gauge has short circuited internally or something.
Would I have any options other than just to replace the cluster entirely to get it working again?
