Question about 2001 Mercedes-Benz S-Class

2 Answers

I have a 2001 Mercedes S430. the gearbox played up for a bit and then would only drive in a low gear. I put it into a garage who connected it up, they said they reprogrammed the ECU and all seems fine now. Is the problem likely to come back??

    I leave the car at an airport in Spain and there is a chance that the car park jump started the car although when I picked it up it was fine. The problems started a few days later, would you expect problems to occur at the time or later??

If they told you that the reprogramming is good then ask for a warrantee so you do not need to take it back to them…knowing Mercedes If anyone played with the programming it will keep coming back this is a temp fix and you need to know what happen to cause it I did the same with my car and I forced them to give me my money back…ask them to give you something in print. let me know Again thank you for giving me this opportunity to assist you Please see that grant me your approvals by rating my service and I hope that I can serve you again the future.

I would say yes. Unless you changed a battery or had arc welding around the car there is no reason for the ECU to stumble like that.

It could have been something different like a loose connection or water in the wires that shorted the brain out. At least it was salvageable.

Try to remember if you drove in a flood or unusual place.

You might try another dealer for service bulletins on the problem or the NTHSA site for defects on your vehicle. Good Luck

    It could have been done when you left the car there. If the keys were with it, someone could have used your car to jump start another. While I never heard of interference from where you park a car, the airport has the most radios and electronic devices in one place that I can imagine.

    Our computer system used to crash everyday about the same time on weekday mornings. The building was 1/2 K away from the road It turned out to be a school bus radio. The bus went by picking up kids weekdays about the same time every morning.

    You never know if they scan for electronics or jam signals for protection around the airport.

I have a Merc c220 cdi 2001.The kickdown works only sometimes and then only once per journey.It will not travel above 85 mph (not that this is a problem).Manually shifting the auto into lower gears works...

Hi Ray
This is an unusual problem the gearbox change is controlled electronically so normally the first thing to do is get the vehicle plugged into a diagnostic machine ( this would also normally require a proper mercedes start diagnostic and not a cheap one at the local garage) But assuming it is electronic you have 2 choices the gearbox control module located in the car just below the gear change lever and the main electronic control located in the oil pan of the gearbox not so easy to access, Just a thought have you ever spilt a beverage such as coffee or soda over the gear lever area ?
as I have seen this problem before with a lack of gear selection it had shorted the module, So I guess for the cheapest first stop I would locate a second hand module from the breakers yard and try this first it should be a easy DIY anything more will require some proper mechanical skills hope this is of some help, Just a last minute thought have you checked underneath for a transmission oil leak as the oil may just be low this model suffers with the "O" ring around the electronic plug failing and causing a leak its located on the right hand side of the box just above the oil pan at the front edge.

Mercedes c class with tiptonic gearbox. It seems to have got stuck in a low gear when I slowed down for a roundabout. When I accelerated to 50/60 mph, the rev counter was way too high and no auto gear...

It seems oil level is low in your gearbox, and it most likely leaking from adapter bushing ( where cable is connected to gearbox).
You need to replace seals or complete bushing and correct oil level.
Better if you visit your mechanic.
