Mercedes dealer are telling me that in my cata converter there is a part that just melt, an it Will cost me a lot of money for replacement.

Try a new battery and if that doesn't work a new one. They cost a lot of money to replace.

You need a on board diagnostic scanner plugged in to locate fault
SRS is safety restraint system, fault is usually seat belt sensor
A good local auto electrician will locate the problem
Main dealer will cost a lot of money
Good luck Barry

depending on the mileage and all, the cost can vary. I can tell you that you do not have to have the dealer servicing your car and buy their package, though. There are companies with way less overhead that can offer the same (if not better) service that you will get from the dealer.. and guess what.. Sometimes the dealerships are even on the lists of 'approved' service facilities.

I used to sell cars, and I would always put a warranty on them to protect my customers (as well as myself). I never had a problem with sites like this one: http://bit.ly/dTgYIN

It's cant say any particular thing as every thing are very important, so best way to do talk with owner and get the car to Mercedes dealer workshop which is the near by your place and tell service adviser your requirement then they will give you a very advance report that's the best way to do it becouse if any simple thing wrong it will cost you too much money for fixing, if you spend little money for checking it worth for you than spend big money for repair, Is this information helped you?

off course but that will cost u lots off money

Take your car to a qualified exhaust shop and ask for an OEM or same quality catalytic converter, it would be a LOT cheaper than the dealer one and you will get the same performance. Remember most car dealers make their money from maintainance services.

If they are replacing the pipes, muffler, and catalytic converter, the job could be $400 - $600. The catalytic converter is $200, muffler and pipes are propably another $100. Labor could be $200-$300

yes you can take it to a muffler shop and either have it drilled out or replaced. They are bad when they are clogged, so if you are in a state that requires no inspections then I would just have it drilled out to unclog it. it's a whole lot cheaper than the dealer is telling you.

too much fuel--- try cleaning the air filter first if this doesnt work then its a sensor problem and i suggest taking it to the dealer as if your not sure what sensor it is then it can be costly changing a perfectly good sensor .

It must be replaced with remanufactured or new one.
Mercedes dealer will charge you a lot to fix it. $2880 or $3000 is about right. However if you take it to independent, qualifying German car repair shop, the cost will be less because they can locate the replacement part cheaper and charge less since their overhead cost is less than at the dealer.
