1990 Mercedes-Benz E-Class - Page 7 - Answered Questions & Fixed issues

Hi, The service will be due at a certain mileage OR a certain date, whichever comes FIRST. So if the service book says it should have an 80,000 mile service, that has come first, before the calendar schedule. It's a yellow warning light, which is a 'first-stage' light. A red light is a problem, a yellow one is just a reminder/warning.! It's safe to drive it, but get it in for it's service as soon as you can as its now over the scheduled service period. Best of luck.

in the fuel duct there is a valve and near the valve is located the valve switch. The best option in my sons opinion who is a mechanic is to just go to a car shop mechanic to fix this, it will cost less in the end.hope you are pleased with my response please get back to me on how this goes. thanks

There is a switch on the dash its the one that resets your milage counter turn it to the left or right this makes the dash light dim or bright

You cannot need to be done on a machine

Easy to change harder to set up without a timing gun you can try and set it up the same checkibg the rotory arm to the dissy cap and turn it slighley to get the car running ok but it would need setting up properly with a timing gun

There are censors under the seat conecting the seat belt to the harness part it ciukd be something as simple as the conector under the seat has come apart but ifvthe belts faulty you would need to replace it fir an mot as its a failure

Faulty switch

Usually the leek is usually yhe crank shaft pully oil seal mine did it cost 3 pound for seal but you need a puller to get the pully off but its an easy job if the keys gone either yse it manually or its around 150 pound for a new key

either front right or front left. front left is normal used for the speedo as well

Yes.

You will have to take it to where they can clear it theres no way of doing it your self the dpf filter xan be done by your self 3 or 4 bolts and a tin of brake cleaner or once a week take it for a good run out as small jerneys make it soot up its a modern day dieasel thing the old ones dont do this

Sounds like the auto choke is sticking on or not working try taking yhe air intake parts ofvthe throttle body and spray inside and out cleaning it as best you can brake abd clutch fluid is the same a good clean could work as its like us gets tyred with old age lol but if that doesent work you will have to get it tuned up somewhere

earthing issue or canbus has issues

Check the o-ring on the 13 pin connector between the TCM and the transmission. If it has oil on it, it will need to be replaced. Also clear any transmission error codes with an OBD II scanner. Make sure the transmission is NOT OVER FILLED. If the problem persists, see your local trans shop.

Best Manuals You'll need either a mechanic, or these manuals. They have info on all diagrams, liquids, how to solve technical problems everything. My brother fixed his Ford 2-3 times himself, using these books only.

Is the on off button working if you dont want it to come on turn it off if you have done that its a faulty switch on the radio and if its anoying replace it
