190e gauges/clock/radio solutions
Just my experience on solving some 190e problems on my 1991 1.8.
Left side temp/oil/fuel working intermittently - changed fuse #9 even though it looked ok and the gauges are now working well. Haven't failed since (a week).
Radio/interior lights/hazard light/clock working intermittently. The clock especially, seemed to work only when the car's engine was off and not when running. Swapped out fuse #13 (i think so-check the fuse box cover for radio/CD fuse) even though it look ok and got everything working fine.
Sometimes, coming to stop at the traffic lights, the engine dies but restarts ok in neutral. I've bought an OVP and fuel pump relay (USD30 & USD50 respectively) and will swap them out tomorrow.
I will run the car and see how it goes.
Hope this stuff has been useful.
