Do you have a spare key? If not call CAA I'm sorry but thats the only solution unless you know how to use a coat hanger trick

you might check the fuse box & relays. and the ac shouldn't cost quite that much if you buy the part yourself. if you tell me what year, model, and engine i can look up part # and cost for you. the labor shouldn't cost more than $300 if you bring your own compressor.

Of course yes if they are the same rim size.

Is it an aftermarket alarm/starting system? If so it may be burnt out. Without the right bosch relays to hold the locks down for 3 seconds the sytem will burn out trying to lock and unlock due to the air pump sytem. They might have also messed with the stock alarm system if you have it on your model which would compound the problem. If the car starts at all I would look at replacing the coil and coil wires as they are some of the biggest contributors to poorly running MB's. Then I would check the fuel pressure, maybe replace the fuel filter and check valve as they can keep fuel pressure low. After that might be a bad ignition switch which I doubt but anything is possible. If you also have an aftermarket radio it is tied into the stock alarm and that may not help your issues either. Hope I have given you a good place to start.

Unless the oil pan is badly damaged then I would not replace it. Tell your technician that you would like the gasket replaced and a new oil plug installed. See if this doesn't change the price to something a bit more reasonable. Hope this helps. Good luck.

change the fuel filter it maybe clogged, check for any vacuum leaks even at the intake manifolds
I would recommend trying STP fuel injector cleaner in the gas tank and make sure you have at least a half a tank of gas when adding and then finish filling it up and take the car out on the highway and drive it to run it through the fuel system and see if this helps and if it does then change the fuel filter

Should be the same as w123 model. Check diy Mercedes web page.
Photos included easy to do.

sound like intake gasket leak.it will leak oil into the cooling system.

check or replace ignition coil,spark plug and spark wire

i guest ignition coil is gone.

it sounds like your fuel distributer is clogged. Replace your fuel filter. first you can try to bleed your system. take 12mm. wrech and loosen up you lines(one at a time) and crank your engine over(with a battery charger)and force your fuel bubbles out of the lines. while the engine is cranking and the line is loose knock on the line with the wrench and you will probably see a whole buch of rust poor out of the loose fitting. do thius repeatedly untill engine fires off-then with engine running loosen up your lines and repeat if any lines loosen up and there is no idle change that means that cylender is not firing and your injecter is not working. These mechanical style injecter's take alot of pressure to open the poppet valve to spray fuel.hope I have been helpful

What you Discribe is Indickitive of The HEATER CORE Leaking into the HEAT / EVAPERATOR BOX Adn Can be Corrected By Replacing the Heater Core. PLEASE Reply for Replacement Procedure. Hope this Helps

The Heater Control Valve has failed. It defaults to full defrost mode when it fails and blows hot air even when the A/C runs. Replacement part is $105 ...google Autohaus AZ for online parts ordering. BTW...HCV is located in the engine compartment right in front of the driver position in the corner by the firewall and inner fender...you'll see small coolant hose running to it.

Bars leak is ok, but if it is a seal, you'll need to drop the tranny pan and replace it. I don't know about Mercedes, but usually you have to remove the exaust pipes to take the pan off.

take vin# to dealership parts department,you can get a new key that will fit ignition and all locks, try new key,if switch does not rotate, replace ignition assembly

it is better to buy a new ignition barrel.it takes a special socket to get the screws out, once the screws are out they do not need to be replaced.buy new barrel,disconnect negative battery cable,disconnect wires from barrel assembly, remove barrel from colum. first take vin# to dealership parts department to get correct barrel assembly, the keys with new assembly will fit doors and trunk
