W124 Solution to a issue on Diesel, Low Idle No RPM Read out/No Interior Lights
Yeah it took me a while to figure this issue out but I wanted to find somewhere to post it. I am sure there is a thread about it.
If there is a spot to redirect me to where I can post a Fix. Let me know so I can Post it there.
These Issue aren't just for Diesel.
Yeah I absolutely Love my 92 Turbo Diesel at 355K Miles. I had the Low Idle, almost stalling issue for a month and would come and go. and be Stuck on very Cold days sometimes.
RPM gauge would randomly not read the entire time.
This issue is probably mainly correlated to when your RPM gauge Stops reading = Electrical Read Out Issue. So if you have this happen, it most likely may fix it.
The Solution was a $10 Part on Ebay. Over voltage Protection Relay
New Overload Relay 201-540-37-45
It's been about 3 Months Trouble free since I've installed it.
*Relay Located Behind Your Battery, Behind the Plastic Panel.*
Only other strange issue I had once was my Interior Lights went out one day. ( I got worried and thought it got burnt out)
A trick that took while to figure out, is to play around with dimmer switch left of your Clock/Reset Mileage
Just wiggle it or turn it and all my interior lighting came right back on.
Just some tips, only owned car for 2 years and this literally only minor stuff. Also check all your vacuum lines! My Headrest got locked because of it once.
Have Great Day!
