Deutz alarm turn off help!!!

[DrDunc]

One of the solenoid valves on the axle suspension block has blown the seals (again ?)

This error code flashes up with a blaring beep alarm. Stuffed speaker with paper and covered it in silage tape, but it's still driving me nuts.

Anyone know how to switch the bloody alarm off?

 

[sidjon]

We put silicon in ours to shut the thing up

 

[7610 super q]

Does the alarm alert you to other issues though, such as over heating, or low oil pressure ?
I'd like to do serious harm to the beeper on my 7840 telling me there's a fuel gauge problem, but daren't.

Think you hold the esc button for a few seconds (assuming it is a profiline)

If that alarm flashes and alarm sound . The tractor should be parked up and not used, there could be more issues, using the tractor like that could be VERY expensive. [emoji51] .

Nah, it's done it before

Seals on the suspension valves are fecked. It's a fault in the 4 cylinder design that it still remains pressurised when switched off.

Probably shouldn't be doing 50kph with the suspension off, but only in the field ??

@Thick Farmer always knows the perfect cure

The 4 cylinder version does not drop the suspension all the way to the stops like the 6 cylinder version does, due to the shorter wheelbase layout the mudguards foul the fuel tank and battery box so the software was written to stop the suspension lowering all the way down.
The suspension lowers in the off position but short of all the way down, this means the suspension is solid , as it is switched off, and riding on stored oil in the cylinders, given that you can’t compress a liquid it is then prone to pressure spikes when the front wheels ride over potholes , concrete edges etc , especially loader and front linkage tractors due to the extra load on the axle, this is what damages the small seals on the control solenoids.
The o rings are easily replaced and an easy fix to the problem is to get your local dealer to change the configuration of the tractor with the All round tester.
In the transmission menu there are two versions of the same gearbox listed one for the 4 cylinder and one for the 6 . There is no difference in the gearboxes in the tractors the only difference is the way the 4 cylinder variant controls the front suspension.
By telling the ecu that it is a 6 cylinder it will
Lower the suspension all the way to the stops and no longer be carrying the weight on stored oil thus no pressure spikes.
The only thing is you might have to
Modify the mudguards or the mounts to stop them fouling the fuel tank and battery box.
Make sure the suspension bushes are in good order at the rams before doing this though as there is little clearance between the axle bolster and the crank pulley when fully lowered and excessive wear can lead to the bolster fouling the pulley.
If all ok once changed and with a bit of modifying you shouldnt have the problem again.
Depends how often it’s an issue as to whether it’s worth the work to modify the mudguards , done a fair few over the years and it’s not that big a job .

Have SDF changed the design to get rid of that design fault in series production do you know @njneer ?

Makes you wonder why (saving ££ no doubt) they didn’t do the update/mod properly - and modify the mudguards/mounts etc - rather than bodging it in software.

Won’t the seals in the solenoids continue to get damaged and need replacement for the life of the tractor? If so seems like a dumb sticking plaster “solution” to an inherent design problem.

SDF sure dont have a good track record when it comes to front suspension (and especially software) to resolve design flaws.

As described the change resolves the issue as the tractor is supported by the stops and not the cylinders so no pressure on the solenoids and it is quite a rare occurrence anyway in my experience it wasn’t ever prevalent ,by any manner of means ,in every 4 cylinder model and as with every manufacturer it’s number of units sold versus number of failures that dictate whether a fix is required so it seems it wasn’t ever prevalent enough to require a “fix”.
The front suspension is a completely new design now and one of the best on the market now.
As for track record on suspension the front suspension was always relatively good but ithat design simply came to the end of its abilities as tractor size and front carrying capacities have grown.
Everyone has seen the one and only ever case of the suspension completely failing which was during , supposedly, closed factory testing for ABS and front disc brake development where , if you look closely, the engineers wrongly had the suspension jacked to the end of the stroke of the rams , where it would never normally travel at, and caused them to buckle.
I was told once that several people got their books for that video being leaked from the R and D department.
Everyone likes to post it and have a giggle and insinuate it was a common fault when in reality it was a single ever event done under (test it till
It breaks and make it better testing).
Have a google at John Deere combine testing where you will find combines being rattled to bits and bits breaking off doesn’t mean it happens to every combine and as such the combines are rubbish.
It’s al getting a bit too tribal on here for my liking with brand bashing ,mostly by people who have never had even had any of the brand , each to their own and everyone will have their favourites and there will be those who may have had a bad experience with a certain brand or model and have a right to their views and opinions but a bit of perspective doesn’t go wrong now and then.
Seems to be a real Fendt bashing trend on here just now and I don’t know why it’s long been held as one of , if not , the best tractor on the market and personally I feel there is a real streak of jealousy with some people because they cannot justify one and felt he need to belittle the brand , and those who have chosen to buy one, to make themselves feel better.
Be nice people life’s too short.

Don’t get me wrong I’m not brand bashing SDF, but from @DrDunc OP this was a recurring fault and wasn’t the first time the solenoids had failed. Surely he’s going to keep having problems until it’s properly fixed.

Well if you're not going to brand bash, I might....

SDF UK don't seem interested in selling tractors, never mind supporting the dealers to fix the odd recurring fault.

I'm not aware that they even have a technical German speaking employee who can ask for help with something as simple as why seals are blowing Inn the suspension block ?

@njneer I've thought of a way to force the suspension to fully lower onto the stops (which I thought mine had been alerted to do, but it's seems I was wrong).

Could I wind out the axle position sensor probe to lower the axle fully onto the stops? If the expected fully lowered voltage position is set slightly lower than when the axle rests on the stops, this will fully depressurise the block.

However, will the controller want to keep the lower valve open because it's not reached the set position voltage?

If the valve is held open by the solenoid, will the solenoid burn out?

I realise the suspension will sit a little lower when in the working position, but provided it still has enough travel to avoid hitting the stops, a little lower will actually be better.

Lower position when the suspension is active will mean increased steering caster angle. That will help make the steering feel more positive, and vastly improves the straight line stability at 50kph.

Still haven't heard anything from my dealer this morning, which means they haven't heard anything from SDF UK about the availablity of the suspension block seal kit ???

Aye, I'm not brand bashing, I think the engineering in Deutz is extremely good, but the support from SDF UK???? Aye.....

 

[DrDunc]

My apologies @njneer but I have another question if I may:

The only seals listed are for the o rings between the two parts of the suspension valves block (parts 7).

The solenoid valves are listed as complete units, but it's these seals that've been blown in the past? I've also had a complete valve replaced in the past as it has stopped working electrically.

Did you get the solenoid seals through SDF UK and not from the Deutz parts computer?

I get in a tizz if a side light bulb blows, not being able to fix the suspension is doing my head in. Thank goodness something serious hasn't gone wrong so far with the tractor, or by head would probably explode ??

I will have a look back regarding the seals .
Your idea of the position sensor is good in procie but won’t work as the only calibrated value stored in the ecu is the value of the sensor in the mid position it is calibrated by setting the sensor to mid range voltage when the suspension is mid range . There is no saved value for upper or lower it is just a single mid position reference point .
I would chase up your dealer if they have not asked SDF the questionthen SDF cannot answer which is not their fault .
I will have a look re seal kits.

It is such a pity, a good product let down by poor backup.

 

[njneer]

If that is indeed the case , as yet no one knows whether the dealer has even asked SDF .
Thats a rather unfair bandwagon to be jumping on without facts ( never stopped anyone before I know!! )
The issue of the small o rings blowing on the solenoids is in my experience a very occasional one and by no means rife and as described above there is an actual fix for it it just requires a slight mod to the mudguards , all the dealer has to do is call their service guy and ask like I did a number of years ago, I am fairly sure he is not psychic , and they will tell them excarty how to go about it , which I have now passed on in this thread so the Op can get seals or a valve replaced and get the dealer to set the configuration up and he shouldnt have an issue going forward.
At the end of the day it’s down to the dealer to either fix it or ask for help.

Had a look can’t find anything , I cannot remember if the rings came in the complete seal kit for the whole valve block or not or whether I just replaced the individual o rings with some from a spurious set.
Either way once the o rings are replaced get dealer to change the config to 6 cylinder variant and you will then see where you need to tweak the mudguards, from memory I think the is enough free play in the bolt holes to move them a hole or two and then pull them to the front on the slack in the holes to clear.

I bought a M420 which had a small hydraulic issue from day one, put the tractor under pressure all the time and causing it to use excessive amounts of diesel, I told the dealer it was a like a priority valve sticking, but the mechanics told me that there wasn't one in the tractor. An expert from SDF UK came over and spent an hour ignoring me and saying it was my machinery that was at fault even though it was happening with all machines and none. The dealer and SDF UK gave me a reasonable deal to trade up to a 6160.4 and I took it. The M420's clutch went on the last day with me, @ about 1,100hrs, surprise surprise the proportional valve in clutch was stuck, who could ever have guessed.
The 6160.4 was a good very frugal tractor, but had the same front suspension issue with the added complications of a reluctance to turn when on full lock, a slightly tighter than usual front diff???? I was offered the 6cyl mod but they doubted it would work with the wide tyres, 600/60/28's, I run and no solution for it's reluctance to turn.
I have now given up on Deutz and traded the most frugal tractor I have ever had because of lack of backup, in my opinion, and my decision was made very easy as my local dealer has changed brand after 2 generations as a Deutz dealer.

 

[DrDunc]

After getting hold of someone at SDF, the part number for the suspension solenoid valve seal kits have been discovered thank you @njneer

If setting the suspension off position to the six cylinder variant doesn't work, with any luck I'll be deaf before the seals blow again.....

..... Then I won't have to hear the bloody beeping alarm again ?
