1986 Blue 190D 2.5 N/A 5 Speed
Please, do this to your fusesHello all! I am the new owner and caretaker of a one owner 1986 Mercedes Benz 190 D 2.5 (5speed). This car belonged to my grandmother since new, and after she passed recently I have now acquired the vehicle. It has been garage kept since its purchase in November of 1986. The odometer reads 109,936 miles, however I noticed on the drive home that the odometer is not working, so we'll add 20-25 miles. The engine is strong, the lights all work and there are no leaks that I have found yet. I wanted to, if possible run by my plan to get the car back up and running more like a daily driver. I planned on first tackling the fluids and filters....Oil (fluid and filter), air filter, transmission (fluid and filter), rear diff, brakes, coolant. Then onto the harder jobs tackling the items that require some love.
First, the odometer needs fixed....so I'm looking at a dash removal. Second, the heater blower motor only runs on max. Even with the switch on 'I' it is still full blast from the center vents. I'm thinking possibly the resistor? This should be an easy kill with the dash removed. Third, no heat. Driving the car home I noticed no heat, granted I had the a/c off because of the fan, but in the garage at the end of the drive...no heat. Also, even with the "floor vents" selected I only get air through the center vents. Vacuum issue maybe? My Dad removed the fuse for the radio because it was only playing static (extremely loud), so replace that fuse to make sure the antenna works. The sunroof won't open....could this be related to that fuse? Lastly, I've seen good things about diesel purge....the diesel in the car is old, I'm not sure how old, but old. Would it be worth it to run some of that through the injector pump? Also, are there any additives to kill algae in diesel that are trusted by fellow MB enthusiasts? I apologize for the long first post but I am thrilled to death to have this car here. It's a piece of my childhood and my grandmother that I will cherish. Given that, I want to look after the car as best I can, and do the work myself. I'm eager to get started on this journey. Thanks for reading, and any input or information given will be much appreciated.
update I replaced the #19 fuse, and the radio, antenna, and sunroof worked. Started the car the next day and the static was back on the speakers so the fuse has come back out. Has anyone experienced this issue before? Is it best to swap the old radio for a new one?
I cancelled the order, thankfully it hadn't shipped. Where can I find a genuine MB cable? Just order it direct from the dealer? Or can I get it online?Great progress. One tip, the gemo speedo cable at autohaus is garbage. Spend the extra $80 and your cable from the dealer.
You will not be happy with the Gemo aftermarket. Mine was ticking right out of the box, it was also not a good fit.. I should have sent it back but I think it ended up in the trash can.
Edit: Just remembered, yours is a Manual Transmission like mine. The Gemo cable is not even the correct length for a manual, even though the part number was correct, it was a bit short. So I would definitely not waste time with that one.
I was able to find the genuine part number and put an order in through pelican parts. It's supposedly the genuine MB speedo cable. Fingers crossed.I cancelled the order, thankfully it hadn't shipped. Where can I find a genuine MB cable? Just order it direct from the dealer? Or can I get it online?
I agree. The only one I found was in Germany but it was second hand. I’m going to email them today and see if it is still in stock. And in the meantime try the GEMO. Have you ever had any issues with the parking brake on your 190? I can’t seem to isolate the reason the Brake light stays on. Possibly a contact in the center console?That is very strange that they do not make them for the European market. There are a lot of manual transmissions there. Too bad.
Hopefully the GEMO will be good enough, it was not for me.
