No, all original, I put it down to being an airport taxi, it had done over 300k in 5 yrs, so it was never cold, the second owner had two other drivers and clocking 90k a year and I change to oil every 7-8k, I’ve had Vitos as well, these were new company vehicles and well thrashed, not real high...

My Viano has 344000 and is virtually all original, it’s had a water pump, alternator and ac compressor, plus a set of injectors, still runs well although I have an injector seal leaking. The key is clean oil and long runs.

Interesting one which could have saved me an hour or two, so I replaced the battery and had to do the usual reset of the windows and lights etc but the mirrors wouldn’t auto fold, turned it back on in the menu tried turning it off and on again and disconnecting the battery again, checked for...

Mine was checked today, rubber band was stuck at the bottom, stuck by corrosion and was still wet but apparently passed the test and the rust marks weren't big enough to need the functional test, but honestly there is no way of checking these propely on th R Class without removing them, he took...

I got the letter yesterday and could have had it looked at today but opted for tomorrow for my convenience, I have the R Class, my understanding is that it is unlikely to fail, I recall they were checking S class vehicles for bottom ball joints because one had failed, yes one! and this was high...

I’ve had three, two Vitos and we have. Viano, Vitos we’re company dual liners, no real issues with either, had both for 6yrs, both well thrashed and only brake pads and normal servicing, had noisy steering on one which needed the inner joint on the column lubricating, the Viano is our own 2014...

I had similar issue with mot, took to Mercedes for diagnostics and no fault found, emissions perfect! Mot station wasn’t revving the engine hard enough, mb did it with diagnostics on which takes away the 3000rpm limit and Rev to the natural stop at about 4500rpm, clean as a whistle, mot station...

Great question, one of many surrounding EV’s, have no fear someone will make one big enough at a price but the huge issue is range and charge point access, I’m hoping to stay with old cars as long as possible to avoid full EV as long as possible, I often drive 400+ miles in a day, how would I...

Why is the pipe to the compressor so poor quality? I bet the one I fitted lasts forever. It’s a bit of old bctr hose I used to use as garden hose and is thirty years old at least, but it fitted and was all I had at the time

Restricted performance, reduced power, limp mode all the same really, where the ecu sees an issue and limits output rather than reduced engine power caused by a fault the ecu doesn’t recognise, I remember one situation where vehicle was undriveable, diagnostics showed no fault so we couldn’t get...

In this instance it makes no difference which way round the filter is fitted as the air moves in both directions, all of the air that goes in also comes out via the filter. Also agree it seems more logical to point arrow towards compressor, my pipe was split and this is why I heard it so much...

You certainly can get restricted performance without the engine warning light, my R done it several times, there was a ti from MB which I found but only after it eventually did throw a light and record a fault, there were issues with wiring on the exhaust back pressure sensors sometimes...

Hi did you ever sort this issue?

This is really old but now relevant, I thought I had a light switch problem so a quick search found this post which highlights my issue, now I don’t have the car with me as we are away in the Viano, same issue drls are set to on so it defaults to auto regardless of switch position, so I assume...

Why is your engine out?

i had similar issue with my R350, exhaust back pressure sensor was the issue, (this may or may not bring light on and may or may not store a code, however if you study the readings they will be off, sometimes reading correct and sometimes reading 0) did the dpf sensor cure the 0 reading on the...

The exhaust pressure sensor is located on the pipe that goes to the egr valve, so if you follow it from the manifold around the back of the engine then up to the egr it is in the last bit of cast pipe pointing upwards, i think thye are a common fail part and some vehicles appear to ignore the...

checked suspension air pressure and it was low at 6bar, as i suspected a leak between valve and tank i removed the wheel arch liner and found the line nearly worn through, as suspected rubbed through on the compressor, fitted a new line and repaired the compressor filter hose as this had broken...

I have had a few Mercedes and generally have repaired and serviced myself, I have a local independent specialist but haven't had very good experiences with him (ripped off with hand brake adjustment and I think kicked the tyres and changed the oil), i'd just bought the vehicle and as it was very...

The V3 has limited function for the Vito/viano i cant use it to teach in new parts but it can do dpf regen and you can read lots of stuff, also disappointing was the function to calibrate the air suspension on my R class, the techs say it will and i've sent some log files for them to look into...
