Yet again another problem! SLK 230

[Janebat]

As soon has one problem is fixed we now have another! O2 sensor was fixed 2 weeks ago, driving yesterday and engine management light yet again appears, tThe esp light has been on ever since new tyres were fitted 2 years ago, plugged in and now we have code P0500 and a P0700 and also the abs light is now on?
Can anyone help me with this at all please,

 

[Janebat]

Can anyone give me any ideas please ?

Sorry can't help Jane, but someone will be along soon I'm sure.

If you search the internet, you find the following............

P0500 Mercedes-benz Description The vehicle speed sensor outputs a 4 pulse signal for every revolution of the rotor shaft, which is rotated by the transmission output shaft via the driven gear. After this signal is converted into a more precise rectangular waveform by the waveform shaping circuit inside the combination meter, it is then transmitted to the Engine Control Module (ECM). The ECM determines the vehicle speed based on the frequency of these pulse signals.

and..................

For a P0700 the only real solution is to acquire a scan tool that will communicate with the transmission control module. Extracting this code from the TCM will be the first step in repairing the fault in the transmission.

OK gratuitous advertisement of the Members Map ..... fancy putting Stoke on Trent on it?

Regarding the ESP and/or the ABS lights, it's possible a wheel speed sensor or its wiring was dislodged when the tyres were fitted. Neither will work if they can't monitor wheel speeds and will bring up a fault indication.

Sounds as if you may have an automatic transmission problem. Electronically controlled transmissions usually have two " speed "sensors- one at the input end and one on the output- this allows the "electronic brain" to compare engine speed with road speed allowing it to select the appropriate gear. First question- how long ago was the transmission fluid changed- it can go off or become contaminated with friction material. If its dirty or opaque rather than clear [pink or maybe yellow] its a sign it needs changed. Certain electronic gearboxes can suffer conductor plate problems its the sort of electronic interface inside the box. These can be replaced if that's the problem. best to get the car to mercedes/transmission specialist with the facility to read the fault codes - many code readers will read engine codes- not so many can handle transmission codes and take it from there.

Will this be a very costly job? And where will the transmission fluid be found

This will give you an idea of what's involved. To a certain extent hours involved will depend on access. First of all you need to get the fault codes read! IF ????it turns out to indeed be a transmission fault then your mercedes / transmission specialist will give you a quote. I would suggest this is not a DIY job as the job requires scrupulous attention to cleanliness best achieved on a ramp with the right tools. A transmission fluid change is a DIY possibility but only for the experienced. Fluid can be obtained from your MB dealer or someone like Opie Oils Opie Oils - Automotive Fluids, Oils, Parts, Tools

Is it safe to drive short distances and around town ?

 

[Janebat]

Is it safe to drive and as far as I know transmission fluid has never been changed...

While its never a good idea to drive a car around with warning lights on the dash what it really amounts to is a calculated risk as to whether damage to you or damage to the car may result. If the car appears to drive normally particularly WRT braking and steering then short necessary journeys-- to Tescos for the weekly shop or to that local MB /transmission specialist to get the codes read/ repairs would appear to have the correct risk/benefit ratio. Continuing to use the car daily to commute to work in heavy traffic or that 500 mile weekend journey on the motorway to visit that old relative you've been meaning to see is not so clear cut. In the end its your car ,your life. your decision.

Anyone with Sat Diagnostics in the Stoke Area?

 

[Janebat]

Is there anyone about who can have a look at the car for me
