Problem: ESP warning (MOT due soon) Question: Should I take to someone with Star Diagnostics? Or buy a 3rd party reader to adapt the Yaw Sensor? Basically, got MOT'd last year, had an ESP fault, but garage said wasn't an MOT fail and kindly gave me the fault codes; C1161, C1152, C1151, C1150 - all referencing B24/15 Rotation Speed and Lateral Accln Sensor. I bought a second hand Lateral Accln sensor and installed it, but looking online it seems it requires 'adaptation'. To do this I need to perform a 'road test', which can only be instigated by a Star machine. However, I did read online somewhere, that a Merc owner had 'accidentally' instigated the road test when using his iCarsoft MB V2 machine. So...I was wondering, might it be worth me buying an icarsoft MB V2 machine to attempt this? Or am I messing with fire? Would an icarsoft MB V2 even help me in this respect? Or is there even a cheaper scanner that I could use? Many thanks. S

Dont tell me you have my old(well it was a mates car I was sorting out) car joking Did you buy an exact like for like (all numbers including the Q number) ? edit I confused myself YAW sensor is the same as Latreral Accelleration Sensor(its been a while) OP B

If so, did they just clear on fitment of new part? Yeah my parts are the same pn and q number. I gathered I had to do some calibration as ; a) this link mentioned it https://www.benzworld.org/forums/w1...al-acceleration-sensor-calibration.html?amp=1 and b) this is what my local Mercedes dealer also said when I called to ask about part numbers and replacement procedures. They just said they could do the adaptation and it would cost about 60 quid. Bit loathed to go to dealers without knowing a bit more about it all, but then but reticent to spend 140 quid on a scanner that I'm not sure I'll need either. Apparently it's now an mot fail (wasn't last year), so I've got a month to sort. Thanks. Sent from my SM-N950F using Tapatalk S

With the incorrect ones the car was fine then the error would come back soon after. WHen i bought like for like no message came up and we were good to go Do you STILL have the warning message ESP not avail coming up? and do you realise that means you have traction off? I had a VERY scary moment (180 spin in wet ) when I had this issue and ESP fault meant for me it was OFF If the warning is still on maybe the unit you bought it faulty or incorrect? I think you need an expert to chime in here , Im just giving you an insight into my adventure dealing with this issue & how I resolved OP B

So it sounds like it's potentially not necessary to do a road test/adaptation. Maybe the second hand unit I bought is faulty, like you say. I will see if I can find another one somewhere and give it a go. Maybe third unit lucky!? Thanks. P. S. Yes 'esp malfunction, visit workshop' still lit up on dash.

Advertised as fully working, but I doubt they've been tested to be honest. Sent from my SM-N950F using Tapatalk OP B

Would the ESP light disappear automatically if I'd replaced with a good sensor, or does the fault need clearing with a scanner (is it stored in memory?). Wondering whether to buy an icarsoft scanner to help... Ta. Sent from my SM-N950F using Tapatalk S

Have you scanned it since then? If you were local I would have put it on my scanner (not used in a while) to see what came up MAybe the new YAW is good. But the fault lies elsewhere with something else? what about the other codes? Wheel speed sensor? ABS sensor ? HAd any work on brakes before this or alignment ? OP B

Where is it bolted? On back floor of boot or under front seat? I wouldn't even consider buying second-hand sensors - you'll only end up paying more in the long run. Get the MB item. The iCarsoft MB II or MB V will detect the fault and clear the code once the replacement has been fitted. OP B

Not knowing for sure it is the sensor at fault, I decided it was worth a punt on a second hand one. Like for like part number. Sent from my SM-N950F using Tapatalk OP B

Installed, and now warning message says ESP NOT AVAILABLE. It said ESP FAULTY with the previous units. What's the difference?! Aaarghhh! Sent from my SM-N950F using Tapatalk S

Whats wrong with 2nd hand if its from a reputable breakers ? It should work? YEs they probably dont test as we said above but £280 for a sensor on a w203 is alot of money Buy a scanner You can always sell it on Or use it for other cars THis is why I bought mine. Sod not knowing. PLus the trail and error side of things its good to have one. GOod investment IMO OP B

After fitting the new second hand unit and initially getting the ESP UNAVAILABLE alert, after driving it down the road a bit, it disappeared! So far (fingers crossed) it hasn't come back! I was so close to buying a scanner too. Sounds like one might be a good idea in the future maybe, but could do without the expense at the moment. Thanks for all the stories/advice...

You can get this is the battery has gone flat or been disconnected. To reset the steering angle start the engine and drive down the road turning the wheel left and right . Switch off then restart and it will go away (IF it WAS the steering angle sensor). A code reader will flag this up if the error is there (not a generic one - an MB specific one that can read all the modules). OP B

OK. Thanks for the tip. Previous codes (#9 above) suggested lateral acceleration sensor, so was concentrating on this, which appears to have worked now, finally. Useful info for the future though. Ta. Sent from my SM-N950F using Tapatalk
