    Could be the quality of the replacement bulbs you are using. Had the same problem a few years ago and reported it when the car was due a service. The bulbs were replaced at a main dealer and had no problems after. Also may have been coincindental:D

    Had mine for 8 years and no blows.
    Do check the complete unit for signs of water seeping in.

    Sounds like a bad earth or short in the lamp unit. They suffer with poor connections.

    Are they blowing or just reported as faulty by the car? My S210 was reporting bad bulbs, it was just the fitting, it needed some TLC, I have a how-to on my repair, PM me if you think it may be the problem, I can’t post it as it’s around 200k

    If they are genuinely blowing it's either poor quality lamps, alternator overcharging or low battery electrolyte.

    re brake lamp blowing

    Thanks for the tips guys, i will take a closer look at the bulbs, they dont look blown but all seems fine when I put new (bosch) ones in. Will take a look at connections too and let you know

    cheers

    As Mercsys has said I have had the same bulb where the car computer is telling me its short but it seems to that the connection on the same side seems to be an issue, so far it has not happened since its last appearance about 6 months ago. I just ensured it had a good connection

    I have a intermittent issue on my offside rear light cluster - I'm told that the unit fails over time. A good clean up of contacts keeps me going for a few months at a time, and is cheaper than a new light cluster for now.

    Thanks Mercsys that was useful. I have a 2000 S320 Avantgarde petrol with the same problem. Showing a lamp fault but no blown bulb, all working correctly. Dealer said I needed new rear tail light units or I could try clean up but not sure how. As I'm a new member I can't PM you but I would love to see your 'How to' on this issue.

    Hope you can help

    #12 the PDFs are attached to #7, but if you can't see them I can email you a copy direct as they are too big for this board.

    I had the same issue on my W210. I was told that over time the lighting unit fails due to the connection failing after over heating. basically you can clean/repair the unit (as others have said), or replace.

    I have had the same issue replaced the metal frame the buld makes contact to.

    I thought it was the light each time because a new light worked when replaced for a short time. I was actually throughing good lights away each time. Take the unit to pieces and clean it up. sometimes you can see evidence of over heating and where the metal has melted away making a bad/no contact.
