    R129 SL500 MAF Sensor (1993)

    A mechanic friend has suggested the coolant temperature sensor, which is a cheap object and I'll try it.

    R129 SL500 MAF Sensor (1993)

    That's about it. I travel from my house to Tesco, which is about 2 miles away, with no problem. When I return to the car, the misfire starts and doesn't go away. Rgds /Phil

    But only when warm? Can't see the logic. Rgds /Phil

    R129 SL500 MAF Sensor (1993)

    Everything has been checked - even replaced the inlet and exhaust manifold gaskets. A Merc engineer said the code showed MAF sensor failure, but as I said, 3 of them being duff? Could be though. I've heard of a lot of people having this exact problem and replacing the MAF solved it - after a...

    R129 SL500 MAF Sensor (1993)

    I have a misfire on my 1993 SL500 (R129). All indications are a faulty MAF. I have purchased 3 of these from breakers on eBay at great expense, and none have fixed the issue. It could be that I've been unlucky enough to buy 3 duff ones so: 1) is it possible to test a MAF, other than by fitting...

    Misfiring 500SL R129

    My 500SL starts OK from cold, but then misfires badly after a short run of a mile or so. The distributor is fine and the Mass Air Flow sensor has been replaced twice - all to no avail. Any ideas?

    R129 SL500 Air Flow Sensor

    My air flow sensor has proven to be faulty (starts and runs for a short journey, but then goes very lumpy). Bought a replacement from the USA (recon - £140), but it didn't work, making me suspect the emission settings for USA models are different from UK models. Opinions? Finally located...

    Side windows scratched

    I had bad scratches on my R129 500SL. Tried jeweler's rouge and was rubbing away for days. They improved by it would have taken me a solid week of polishing. Decided to buy a replacement window from eBay which was described as VGC, but it has scratches in exactly the same position. Got a full...

    R129 300SL beeping on starting

    Issue resolved. The alarm sounds when the back of the seat is not firmly locked into position.

    R129 300SL beeping on starting

    My R129 300SL has recently started beeping from the rear of the cockpit on starting. It lasts for about 10 seconds and then goes off. There are no dash alarms showing. Any ideas what the car is trying to tell me?

    Odd noise when turning the steering wheel R129

    I have the same noise, but have always put it down to the tyres being so wide that they scrunch/slip at slow speeds when turning in car parks.

    Too much condensation

    I have exactly the same issue with my 129. I suspect rain is not being cleared from the base of the window on the outside and the drain holes have become blocked, which leaves a large reservoir of water ready to be heated and pumped into the car whenever the heater is used, only to condense...
