CLS shooting brake, SWMBO has B class
Hi all, got a recall notice from MB about replacing the bolts on the steering rack/pump. Got it booked into MB Norwich and they mentioned that they could also do a software update to the engine management to do with emissions. So question is do I let them do the software update as well, or not!??
 
How do you stop them when they have it in their possession?
The software is theirs so can't they do as they want with it?

Hey, did you make a decision on this?

Duct tape the obd port with a note saying don’t do it , after all it’s your car . This is different maybe if you are within warranty and need something doing ?
 
I will instruct them NOT to do the update and I like the idea of putting duct tape across the obd port.....

The car is yours, they have no right to alter anything on it without your consent unless it's an official government recall for safety reasons. Tell them it's been remapped and it will cost them £500 if they change anything without your agreement.

I had my CLS done last week but no mention of a software update. They will also do a “complimentary” visual inspection whilst it’s on the ramp. This is fine albeit they may flag some small issues, of which they’ll send you a video and ask for your permission to fix.
 
There‘s a good thread on this topic on the other forum (IIRC - will try to find and post link). There are two software updates, one to ECU one for the TCU, the result is reduced MPG following the emissions scandal. The thread advised the software updaters are optional in the UK (at present, interestingly mandatory in Germany). The consensus is to not have them done as optional, in addition to the reduced MPG, MB do not appear to be able to restore the ’as-is’ map.

Is it the Mercedes Benz Owners Forum? If so I’ll have a look. I’m a member on there but don’t often visit. Is it as active as this forum?
 
My S204 went in for an airbag recall. I gave them explicit instructions not to upgrade the software, and I taped over the OBD port.

They were absolutely fine about it and said that's no problem at all. The OBD port wasn't touched and no software was altered (I could tell from the way I taped over it)

Its your car not theirs ;-)

Yep, here’s the thread Update on the Recall update. - some interesting info on how the ECU and TCU updates change performance/characteristics of the car and also thoughts re IP and changes to the software in the ECU/TCU.
 
If it's the diesel software update I would advise NOT having it done. My E350 went in last year for an airbag recall and they stated that they would also undertake a 'free' engine software update. I told them over the phone that they were not to do it, told the 'service team leader', on the day, that it wasn't to be done and a note was made on the papers. However, I also stuck a bl**dy great note, highlighted, on the dash and another obscuring the speedo etc to ensure that the technician saw it.

It wasn't done.

There have been many threads about it, numerous people less-than-happy after having had it done. It's your car after all, not theirs. To be fair to them they simply said 'that's fine, we've had a few customers not wanting it done, we will not do it'.
 
MB should have learnt their lesson, yet they continued to use T bolts and used them to hold down the steering rack, the same kind which were used to screw down the heads on the M156 engine. Basically they can potentially snap if corroded badly as they have less material at the top of the bolts which weaken with corrosion. They should have used E type bolts from the beginning.
