Mercedes code resetter needed, must be really easy to use (1 Viewer)

[andy63]

Oi you two, I am here as well you know

Sorry..

if not failed not sure what they will be looking at / for

That's been mentioned and pointed out to me in a previous post that the codes clear and reset after you shut down and restart... I'm not sure...
All I know is I've had codes stored without a light been on.. Some of them most probably relating to work I was doing and forgetting to reconnect something...
All I'm saying is ring.... let someone who knows tell you..
Look you've got me rambling again...
Andy..

I promise to call someone next week, you are right the codes are stored, unless wiped by one of the scanner things that I have just bought the issue seems to be interrelated between sensors, just need to find the right one to change first time hopefully

or just drive it till it busts, now here I am going back round in the same old loop again

you worry too much for everybody Andy, but your concerns are appreciated

Yes the codes stay recorded even when it resets by turning ignition on/off. Fords are the same. I fund there was no need to stop in the end . just turn off & back
on ,engine fired ,still in gear . carry on

A little more exciting to try that with a full auto though

Oi you two, I am here as well you know,

Terry you said your man needed about 2 months notice to get in, I need far more spontaneous reaction than that

Andy, problem we really have is getting it to the workshop in a failed state, if not failed not sure what they will be looking at / for

It was more than two months ago and he is not my man only used him once when all else failed he found the fault for £60 quid =money well spent

Try holding it in second gear and thrashing it down the m/w for 20 mins that may clear it's brain or break it either way it could produce a result
You can always borrow my new trouble free van David ----you know I MEAN THAT

We had a fault on our 2.7 Sprinter, ironically whilst waiting to go in to the MOT bay at Nottingham City Council Transport depot. The place is full of HGV mechanics as this is where the councils fleet of vehicles is maintained. A guy in overalls came over and had a look under the bonnet. Bear in mind Id just driven there 20 minutes before, the guy said it was probably an dodgy injector. We managed to start the van again and continued with the MOT which ended as a fail due to rear brakes needing replacing. Took the van straight from the MOT place straight round to Mertrux who we had used before. They did the brakes and sorted out the alleged injector fault ----- which turned out to be a faulty crankshaft positioning sensor. The van has never missed beat since - he says touching wood.
As stated previously , there are some features on Mercs which only Mercedes dealers can pinpoint and subsequently fix. Get yourself booked in to one and stop fannying about.

Another little point worth remembering with the scanner/code reader...
What codes are you actually looking at..
Your vehicle is most probably obd11 compliant (think commercials had to be from 2007 )and a scanner will be able to look at those codes... but that's not the same as manufacture specific codes... The reader would have to have some manufacturer specific software to read those codes.. and it might again that's my thinking and a point worth checking....
I look forward to hearing what a good diagnostic place has to say.. may come to nothing but worth a try..

just need to find the right one to change first time hopefully

That's where the scope comes in... takes the guesswork out of checking suspected faulty sensors or actuators.
And may be possible to have it running under live conditions to catch even an intermittent fault..
Andy.

i assume terry is leaning towards a carbon build up problem, probably around turbo. if its low mileage and been driven carefully / slowly, then may be" terraclean" would help. thats if you can get it back on the road...reading the codes will only point you in the right direction i.e. low boost etc. its not magic, the operator has to use his experience/knowledge (or get lucky changing parts at your expense). anyway I'm following the thread with great interest, and hope it doesn't break your heart, or wallet. best o' luck with it David
