My 1984 300sd will keep running after the key is out of the ignition. I do have a new shutoff valve to replace, but have not gotten to it.
Well, I figured out why the engine cuts off some times before I get the hood up. When I'm getting out of the vehicle I tapped the brake and it killed the engine. I do this with regularity now. Has anybody heard of this? And if so, is it still my "shutoff valve" or a vacuuum booster to the brakes?
having trouble starting. This is my first (not last) mercedes. Its an 84 300SD. Hot or cold does not seem to matter. When you've waited for the glow plug light to disengage and try to start it either will or won't. Some times it starts right up others you can wait up to ten minutes. The battery appears to be fully charged. I can hear the starter gear engage. I'm leaning towards the ignition. I don't know if this is a common or easily fixed situation? The car has 267,000 miles shes just getting broke in:). I appreciate anyones suggestions. thanks benzbear68
Idle problem getting much worse.
Help if you can. My '87 6cylinder SDL is a little different than older models. However, my idle is driving me nuts. The car has been running great for years. Last month every once in a while when Hot the engine would Rock/Roll at idle. That idle problem got worse and worse. It is intermitent & used to only happen after the engine got to hot operating temp. Now it happens at all temps and is still intermittant. Sometimes it idles just beautifully. I've inspected the entire fuel system, replaced most of the hoses and clamps, replaced the fuel Pump. My IP is a little different than pre '87 Mercedes, so I don't have a dampner bolt and my ALDA looks different than older models.
Any suggestions on what to try and adjust?
Hey guys and gals.
1984 300SD
142k miles
I have had it about 8 months
I have changed both fuel filters and purged about 5 months ago.
It has a fairly fresh oil change and filter about 3 months and 3500 miles ago.
It starts and runs very easily and well.
It kicks down and shift correctly (sometimes a little jerk on upshirt but really minor)
All my vacuum stuff works
When I drive the car it start and warms up to 1/4 the way above 80deg on the temp gauge and stays there if it matters.
I have a 1985 300SD. The speedometer work fine but the odometer does not work at all. I pulled the instrument cluster and discovered it is all electronic. What should I look for to troubleshoot the odometer?
will a transmission from a 1981 300sd fit in 1980 280se with a 126 chassis
Hey folks, first time posting, newbie mechanic, just bought a pair of these 1981 300sd turbo diesels, one a (previously) running parts car, the other hopefully a runner, my first cars in 4+ years, my first mercedes, and my first diesels. So, here's my problem.
