Len,,how do you know it is the valve and not the control unit

'cos its a common issue.

Unless you are competant don't attempt it as its filddly and you can break the plastic bits on teh hoses easily.

Mercedes have said this is 99% the part.

I'm not fitting it myself.... I know a merchanic who wants to know some more info...... how much would you charge BlackC55?

Thanks

If you get stuck I can give you the job sheet

You take out the scuttle pannel trim, wiper system and then struggle like hell to remove the wiring connector and three hose connections. these are held in by a metal circlip type clip which lifts up. The whole thing sits/clips on a little plastic bracket.

Not easy at all and the first one takes you ages.

Part 30 in the link is the switch over valve and the clips are 40.

Not quite that simple call to the post office, then 25 miles to Exeter to pick up my new boot gas struts, in to the carvery for 12pm, finished by 12.30 Picked up some car spare parts and home for 2pm, gas struts fitted by 2.03 pm and back to a pumpkin for the rest of the day, there must be something more to life:sad:

I have searched but there are no instructions for changing this valve ???? first thing that I have never found

 

[len_merclover]

ok thanks matey

 

[len_merclover]

All fixed!

Hey Guys/Ladies

Thank's for all the help/advice into my troubles with my non-heating!! Could not cope any more cold mornings !!

I have had the DuoValve replaced last night and now all working. I can't understand how Mercedes can see all this similar issues occuring in the same models etc and don't do anything.... it's obvious there are problems with the duovalves or maybe they only last 5 years!!!

All the best

Len

We do not get so much problems with these things, its mainly the cars that are 20years old where they fail.

They work on a pulsed signal,, this is an easy way to keep a valve in a certain position.

Pleased that you no longer have cold feet Len

Hi Len,
what did it cost in the end then?
Mine is fine now but it had another hicup at the weekend so I'm hedging my bets .....

 

[len_merclover]

Total = £100 inc labour

 

[jberks]

Total = £100 inc labour

Great - thanks. All ok at the moment but nice to know it won't break the bank.

 

[len_merclover]

Ha, yes could have been something more expensive!!
