[mercman111]

its a 55 reg and a coupe,everytime i switch the ignition off and back on my parktronic light in the switch is alight and the parktronic does not work

You need to get it code read to resolve. Similar happened to our 2007 CLK and the code reader pinned it down to a specific failed sensor in the front bumper which I replaced.

My 209 parktronic plays up often too. I've just resorted to manually turning it off every time l start the car. I'm not impressed with the parktronic system at all so haven't bothered to get it repaired. The sensors on my mate's 20 year old Toyota are vastly better.

droverunner were did you buy from

 

[Droverunner]

From Ebay I guess about three years ago. Supposedly new Bosch but the price was so low I did wonder. Anyway they have worked fine ever since.

Re the Parktronic as a system... for me all it needed to be perfect was nicely graduated beeps rather than just that final beep as you are very close to something. My 5-series BMW had these and it was so much easier to listen rather than looking at the displays... particularly looking at the Mercedes one in the rear mirror.

did you have to remove bumper

 

[Droverunner]

Yes... not too bad once I'd worked out the fixing locations.

This thread for my diagnostics...

2007 CLK Parktronic. Diagnostic & replacement front sensor choice.

Bit of help please. Our CLK of 6mths has thrown up its first issue, erratic and now failed parking sensors. Background when we first had the car I ran a full diagnostic with iCarsoft i980 and found historical codes of all the front parking sensors faulty. I can see it's had a replacement bumper...

its a total failure back and front does this make a difference,the strange thing is its not on the computer

 

[Droverunner]

>>> strange thing is its not on the computer

Which computer do you mean?

 

[mercman111]

the one thats fitted to the car

 

[Droverunner]

If you mean the car's own warning display no that will not diagnose a fault like this... you need a Mercedes specialist with a code reader or a DIY code reader like the iCarsoft.

 

[mercman111]

i have an mb2 i did mean the cars own warning display

 

[Droverunner]

Assuming you mean an iCarsoft mb2 then yours is a newer version than mine and ought to help you diagnose where the issue is.

 

[mercman111]

i have put it on the car and it comes up with A42b3left inner sensor (front bumper)

 

[Droverunner]

That's good.

 

[mercman111]

what is the one thats knackered

 

[Droverunner]

Just confirm by bringing the car to a wall and looking at the datastream for the distances they are all detecting compared to the actual distance to the object. My failed sensors were so obviously wrong at 0cm.

what is data stream
