The Eternal Unbreakable Triangle..........Mercedes-Hymer-Dealership

In March 2015 I bought a Hymer MLT 580 which is basically a small Hymer MH on a Mercedes Sprinter. It came with a small number of snags but nothing more than any other motorhome I've had.

The Sprinter is dedicated to the UK with right-hand drive, instrument panel in Imperial measurements, mirrors and wiper acceptable for driving in this country. There are alterations you can make to the dashboard display to show metric and this is useful when going abroad to have a MPH speedo' and KPH digital readout at the same time.

Then I discovered that it didn't show Miles per Gallon but Litres per 100/Km and I cannot change this to Imperial MPG. An annoying factor as I have always found this an early indicator of problems. The Sprinter advertising talks about MPG, the 'miles' left in the tank are displayable so the calculation is being done in MPG but I am being kept out of the loop.


Step 1 ...... Email to Dealership. Ignored

Step 2 ...... Email to Mercedes Customer services.

Thank you for contacting Mercedes-Benz Customer Service.

I have contacted our technical team regarding the mph display settings on your motorhome. They have advised these are not set by Mercedes-Benz so have recommended you contact Hymer directly who should know whether changing these settings is possible or not.

Should you have any further requirements please do not hesitate to contact me or any of my colleagues.

Yours sincerely

I thought it was the Mercedes computer?

Am at bad waldsee at the moment.
Technicians back Monday, so will ask.

If there's a trip computer on the vehicle, they often have the option to toggle between imperial & metric measurements.

Thanks ..Sue, much appreciate it. This one option you cannot toggle, cannot get any sense and is driving me crazy.

 

[Theonlysue]

I struggled to get mpg, unsuccessfully.
Mind you, took me 3 weeks to find out how to zero the trip meter

Hymer are house builder, the electrics are all Mercedes.

You might get more results hunting round Mercedes forums, there must be a lot of similarity between car/van chassis in the electronics, they won't have a different software team for each range.

I have a 2015 Mercedes Sprinter under my Frankia and it too displays Liters per 100 km. I do not have the ability to change it so I now have an app on my phone that will convert it but it really isn't too much to do in simple arithmetic.

Mine works out often around 15litres/100km.

I work it out as approx 60 miles to 100 km and roughly 5 litres to 1 Imperial gallon.

So I'm using roughly 3 gallons to 60 miles or 1 Gallon per 20 miles. i.e 20mpg

In truth 14.182 litres per 100 KM = 20mpg so I'm around 18-19 mpg simples. I keep a spread sheet going on as I put the miles on because I have seen some pretty optimistic trip computers in my time so I keep a check as any change is a good indicator of performance issues. I have also noticed just how accurate this trip computer is.

If I remember correctly scroll through until you get to KM's then hit the mode button, this should change it from km's to miles.

 

[sallylillian]

Also the calculation is not actual fuel used but a computer model, I have an Iveco with MPG readout and I meticulously keep fuel and miles records on an Android app, the vans MPG is always more flattering than the actual!

except on the Mercedes Sprinter like mine.

However, I am prepared to be corrected, but I think this just does the Km,s to Miles on mileage covered not MPG.

Like @Popeye I use the very simple method he describes. Except there is actually 4.566 L in a gallon

today I drove to work in my van and recorded 10.8L per 100km after a while I do not have to even think about it now, I know pretty much two things. One how quickly I can convert things, two, how crap MPG is

simple exercise, drive at 50-55 touring on cruise and I am about 24 mpg..

Get that big V6 Auto purring where it should be sat around the 65-70 and reach for the wallet it's 18-20 mpg

What a surprise, we'd never expect that, would we.

 

[Popeye]

Like @Popeye I use the very simple method he describes. Except there is actually 4.566 L in a gallon

In fact there are 4.5461 litres in an Imperial gallon but to round up to 5 is close enough to see if there is a marked change in fuel consumption.

My trip computer will change from metric to Imperial and Fahrenheit to Celsius but it will only give fuel consumption in Litres/100 km .

[haganap]

@Popeye see, knew you were wrong... At it again, spouting rubbish off, I have just been and got official confirmation from a physicist friend of mine and the answer is actually 4.54609 L per Gallon. you should be more careful, this could lead someone to thinking they are getting "22.179" MPG as opposed to "22.17856" mpg and hence make them regret the day they purchased that van over the Iveco.

 

[dabhand]

Agree with Paul and Griff, Hymer with Merc Sprinter engine 18mpg unless I drive like a geriatric vicar and can nurse about 20mpg out of it, doesn't make much odds, still get 18mpg doing 70 on motorway. Speaking as someone who had occasion to read the manual in great detail ( not something I normally do) when his whole dash reverted to German as a result of messing with the various button in the middle of a journey, I would confirm that you can change most perameters but not km/litre to mpg, well I couldn't anyway. Be interested to know if there is a way to do this though! Oh and if your too worried about your mpg you can always get on your

 

[DavidG58]

mine gives mpg, on a 2007 chassis so might be older than you lot though it was like that when I got it so not sure how and not really keen to swap it back to metric in case it gets stuck there

[Xabia]

I wouldn't bother with the computer read out, my x250 Ducato tells me I get a near constant 26.8 mpg, brim to brim checks reveal that the true figure is 22mpg so I have stopped looking at the readout.

 

[Minxy]

I must admit I much prefer KPH to MPH anyway as it is easier to do the calculations and also the km just go so quickly when travelling that you feel like you ARE getting somewhere!

Ah but David, yours is a one off.
