Hello fellow members I have just been accepted into this group and I thank for that.. I have been very active in another group for Bailey Motorhomes for the last 5-6 years but due to a couple of near death experiences ( not my fault ) on our Scottish west coast roads I traded it in for a 2017 AMG Marco Polo which I have had for two years and still getting used to the size compared to the six berth waggon I had previous.
I am having some problems with it as it has gone into limp mode a few times and the error code came up with the mass air flow sensor which I have had replaced but now a different code has appeared with a low boost pressure on the turbo and this fault is intermittent.
Can anybody on this group point me in the right direction possible causes ?
The vehicle will be going into a garage soon for its next set of tests to hopefully find the cause TIO

Hi and welcome, I think engine issues are less of a worry as its just a V class merc, so should be fixable by a decent garage. The habitation area kit is slightly more worrying as you need to fix yourself or find a trade nearby who is willing to do it. Hopefully you get the issue solved soon and enjoy the last of the warmer weather in it.

Unfortunately a standard garage hasn't got the fancy code reading unit that's required to diagnose what the problem is via the merc codes. I have tried two local ones and they have both given the same result that the engine is running lean. another garage which has the proper diagnostic unit replaced the max air sensor then after a week the limp mode appeared again and now the code says low turbo boost. I am now going to try and get the extended warranty company to take it to the merc van and lorry company in Aberdeen for them to fix if possible but the last visit to them cost me £3k as the warranty didn't cover the full rear electronic parking braking system as it was classed as wear and tear, now really getting fed up with it all
