W202 dash light broken - how to replace? - MBClub UK

philepo · 23-02-2010, 03:03 PM

Hi

Does anyone know how easy it is to replace a faulty light in the odometer / mileometer?

I'm guessing that if all the other lights are on then this isn't a separate fuse?

Do I risk setting off warning lamps / air bag faults by diving in there?

Cheers.

Hi,

It is the milometer readout that is now dark. The LCD is working cos you can see it in day light or with a torch, but the back lighting has gone. A bulb? Any ideas how to get at it? Cheers!

The cluster has to come out, easy if you have adjustable steering, the ignition must be OFF while the 2 connection plugs to the rear of the cluster are disconnected otherwise you will have an airbag warning light on all the time, requiring a reset at dealer. Steering wheel removal is not required.

This may not be exactly the same as your car, depends on year of your car.

I know what you mean alright, I don’t know a lot about your particular problem, my reply was aimed at Philepo, others may be of more help however it would seem that you have two options;

Pay for the repair … Cluster Repairs UK - Instrument cluster speedometer repair, correction, modification and spares.

Fix it yourself, I believe this involves packing out the ribbon wire that feeds the LCD screen, contact is lost between the ribbon at the PCB board resulting in your symptoms. See… Auto Repair Tips: February 2009

Dec,
I tried this and the cluster will not budge. I decided not to force too much incase i break anything. How long are the prongs on the end (the hook bits). Mine were 1 cm long.

Cheers, Philepo

That’s way too much, about 5mm is about right, there are exact measurements and design in a picture if you scroll down in this link here… Removal and Replacement of Expansion Valve
When you are pulling make sure the hook handle is horizontal at all times.
My hooks arent a great example but the do the job ok.

Another method is to remove the panel under steering wheel at driver’s knees and push the cluster out from behind.

Edit
This is what can can happen if you get it wrong and don’t keep the hook handles horizontal when pulling, hook slips and tears a chunk out of the glass on the way out.
Solution to that is to get another cluster from a scrap yard and swap over the front, glass part of the cluster.

As per Dec's post above , the hooks are way too long.

I have done mine before and and it was very tight to remove, so I had to push it from from behind as well as tugging it with home made hooks.

Thanks for the advice. I am going to leave this job. It is one of those things that irritates me that it is broken, but I would be unbelievably cheesed off if I broke the glass or set off a warning light.

Not worth it! Thanks tho.
