Hello fellas, well i’m a new owner for a 2.3-16 87” the car was an exelent shape And the frame was inmaculated 123.000kms on the clock (euro) And evo 2 wheels 8.25x17. i have an issue. When o put the key in 2nd position the check lights in the cluster doesnt lit up (just the battery light lit up) when i start The car the battery light went out And the alternator are in 13.6 with running engine. But if i connect the systems with a wire, like the windshield water sensor, coolant sensor, brake fluid the lights in the cluster lit up propperly. So my only problem is the system light check with the 2nd position key And engine not running my cluster lights doesnt work.

Someone with same issue?

Thanks in advance

Welcome. Pictures would be great. Pictures of your dash to see which lights are doing what when will also help. Might be a number of things. All of your dash lights should briefly light up while you're stating the car and then they should quickly go out once the engine turns over. Might be a fuse, a sending unit etc.

Fabio D

Yes Friend! I will post some pics tomorrow. What is the sending unit you refere? This is my problem, the briefly lights dont lit up in 2nd key position, but lit up when i bridge the wires in the sensors. Might be the alternator but they are replaced by a bosch remanufactured And shows 13.6v with engine running 😐

Thanks in advance

Maybe not the sending unit since you say it works in position 3 but not position 2. Might be a wiring issue. Check the condition of all of the wiring and connectors to be sure it's all in good condition and that no dirt has gotten into any of the connectors would be where I would start to look.

So, this is the key in 2nd position, the check lights would stay on before engine starts. And they are all dead

Engine not running

Engine running (i have some idle issue that i solve soon) And the battery/alternator goes off like it should do perfect.

Engine running

whats the sending unit you refer? You mean the instrument panel?

It sends the signal to the dash light to light up. I would suggest your purchase a Haynes manual for the 190. They're not real expensive and they have alot of good repair information on all of the various systems for your car.

Fabio D

can you please guide me to buy this manual? You have any picture of this? And where os located this unit you talking about? I’m thinkuna about that if The car has some unit to lit up this lights. I replace (by my brother’s car) the large relay located in the fusebox, all the aluminium relays, fuel pump kickdown relay, i try other Jetronic, other abs control module :/ And nothing.. the wires seems good by the way. But the fusebox was replaced in the past by the service records. Maybe someone change a wire in the fusebox? :/

if you can guide me where is located this sending unit you mean i can change it to my brother’s car to see how it works

you think the haynes Manual for the 2.3-16 os pretty close or same as the normal 201? Cant find it for the cosworth

Go to www.haynes.com. I would think the 16v would be the same for the lighting cluster.

Fabio D

Maybe this is the problem? Burnt resistor?

??? Problem? Anyone ??

That's not what I said. Haynes only produced 1 manual for the 190 and no separate manual for the 16v. I would think that for the wiring cluster the 16v might be similar to the base 190 so the Haynes manual might help you. My 190 is not a 16 v. You might also try www.startekinfo.com. That's the MB portal but it's very expensive. You might also try www.mercedes-190.co.uk and the W201 section for www.benzworld.org. There are 190-16v owners who are active in those forums who might be able to help. The 190 section this MB World forum doesn't seem to be very active.
