Hi - is it common for the Vito milage indicator to go dim/actually disappear? Recently purchased vehicle - but the annual MOT certificates tally with the indicated milage (when you can see it) Could this be related to Limp mode?

Thanks
John

Hi John, this will be one of two things, either the led's that light the mileage up have blown, easy fix, or the ribbon cable behind the dash has either cracked through or is not plugged right in which is a right royal pain because its fiddly but again is common and doable

Thanks

Thanks for thoughts so far - I'm taking it that it's unlikely to be connected with limp mode as neither of you mention it...and you both seem to have a fair bit of experience:) I will feedback on this once solved - the other idiot lights do tend to glow dimmer and brighter, apparently randomly...I will be checking all the earths when I/she have time to do that under-dash yoga with the patience needed!

Code reader (ebay cheapy, but has worked with various cars in past) adaptor, unpacked friend popping past a bit later...new fuel and air filter were certainly needed...and are in too.

Cheers guys - great resource - and I hope you busy professionals get lots of good 'karma' back. (yeah...I know...but the oldies are the goodies :)

Vito 110 CDI Limp mode feedback...

Hope that title will get picked up on search?

Well we'll see... the cheap codereader said EGR. So I've checked vacuum pipe after vacuum pipe (all good), lain under the car checking actuator (gets noisy from engine rhs about 3000rpm?) and have just removed and cleaned the plastic intake manifold which has the egr sensors. Haven't weighed it, but I guess just about a kg of carbon from it and egr valve. 103 000 miles...I'm off my map, is that usual?

So the sensors might be good, the pipes all good, but if the manifold is full of carbon??? Hope that's it. Of course it has the glowplug light on still...but it arrived in limp mode and is now out of it. I guess a bit of wire or a drill bit through the manifold vacuum connector might save stripping the manifold off for a while...and as a diagnostic check.

There is some oil around front of turbo...not enough to drip yet, and vehicle isn't smoking, or turbo noisy. Exhaust is going to need replacing (interesting old threads on that....I think we'll play when the time comes, but it's not bad. I pulled the cover off (PCV valve elbow connector UGH!) and no sign of 'black death' I read so much on :) Tomorrow my Waxoyl pressure kit arrives...we looked at quite a few Vitos, and this (spanish) one is so rustfree underneath we decided to throw some money at prevention...ho hum...

Thanks for all the help Benzworld:thumbsup:

Final paragraph (I hope) in this chapter for the 110...A top notch Mercedes specialist diagnostics computer proved my cheap ebay one (Autel) is NOT clearing the codes, possibly not even reading them all. It pointed to the Turbo boost regulator and after checking all the wiring and vacuum pipes I replaced it. Voila! Of course immediately I started the car the headlamp adjuster switch started hissing...after twiddling with it a bit it stopped...

Let the lesson be learned...DECENT/DEDICATED scanner/diagnostics machines are worth their weight in gold!
