Question about Mercedes-Benz Mercedes Benz A Class Maisto 118 Red

1 Answer

Yellow engine diagnostic indicator light, p0700

Hi, I have an A-Class Mercedes, 2004 model. It is an automatic car. It has done only 30,000 miles. Few months ago, we replaced a gearbox. Couple of days ago car broke down again and a towing company noted the cause to be P0700. What does it mean? The car is completely immobile. Engine turns on but car does not move at all. I can't take it to any mechanic as it does not work. I don't want to spend too much money on it again. What could be the possible reason for this? If I can get an estimate of repair, that would be great. Your time will be greatly appreciated. Thanks

SOURCE: mercedes a class gearbox gears

If you take it to mercedes they will charge £3500 and will replace the gearbox, Alternatively you can change the shifter valve £25, new sump and filter as they have changed, fit a magnet inside the gearbox as the early A didnt have one. Fresh oil and see how you get on, the control unit for the gearbox sits inside the gearbox £1000 roughly for a new one but it has to come from mercedes in germany where it is coded to your chassis number, 2nd control units are not an option!!!!!!!

SOURCE: 1995 mercedes benz c220 electrical concerns

the electrical needs to be looked at as the wireharnesses on these models is very britle.
the wire cases shead off and leave the exposed wires to short out on each other in the harness.
start by looking under the hood and checking for this condition in any of the visable wire harnesses.

if you see any sign of wires sheading there casings do not touch anymore as the more the wires move around the worse they get.

my c280 had this problem and it was 2k to replace the bad harness.
benz did the work.

this is the only thing that will contribute to your complaint of multiple electrical fuses and bulbs burning out.

The check engine light comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to AutoZone or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.

A flashing check engine light is an indication of a severe misfire or problem that is likely to harm your engine. Immediate diagnosis and service is needed.

Some specific causes for the light to be on are:

Gas cap left off, not tightened, not installed correctly, or needs to be replaced

02 sensor

Engine misfire - error might clear itself after 3 complete warm-up cycles; not restarts, but warm-ups

At start up for a bulb check - Should not stay on

Problem in the emission system, including clogged exhaust or the catalytic converter not functioning properly

Dirty/clogged air filter

Dirty MAF sensor

How often should i tuneup my 2004 nissan maxima

Same as on all your vehicles

The same as you have done all your life

Tune-ups went by the wayside 25 years ago

Spark plugs etc--every 3 years or 70,000 miles
Filter -every 3 years or 30,000 miles
Brake fluid every 2 years
Trans& Power Steering every 30,000 miles

Set up your own schedule from past experience

I assume you keep no log book, if have to ask

*Owner of Mecedes C230 Model 2004. 271 engine. Done 85K miles * Check engine light come on when speed at around 135km & misfiring. * Switch off & restart the engine, is ok but misfiring again...

I know what the problem is. It's going to cost u about $25,000 to fix the problem. Just buy a new car and dump that crappy piece of metal in a river. Mercedes Benz will never be on my wish list ever again. Even the mechanics can't figure out the problem with my check engine light after I pay $2,000 for a check engine light service. They F***** it up even more. My car now is in line to get a heart transplant because it's dying.

Do I need to change the gearbox oil? if so after how many miles. the car is Mercedes c200 auto.

Every 50,000 miles is a good bench mark. Mercedes recommends a specific oil for your transmission.

I suggest you visit you local dealer and either have them do the job, or supply you with the oil and filter to do it yourself.

You will need to measure how much fluid is removed to refill. The torque convertor needs drained to and needs a ( #40 ?. ) Torx to undo the drain plug.

Total dry fill is 8.5 Quarts US. You will be able to drain around 7 Quarts if you drain the torque converter or about 3 Quarts if you only drain the pan.

I usually recommend 30,000 to 40 ,000 mile intervals if the vehicle is frequently city driven or a grocery getter. If it is a mostly highway driven vehicle, then 50,000 miles. .
