E320 Auto gear box issue

[Jerms]

Hello all,

I am a new memeber and was hoping for some advice please.

I have an s reg E320 automatic estate with c 115k on the clock.

I have just gone to go out this evening and got100 yards from home and the car has suddenly become jerky (doing under 15mph) and after pulling over and re-starting the gear box seems to be making a noise like 2 things rubbing together and obviously the car will not run.

If I put it into drive in either S or W and try to accelerate, it finds a gear but is really jerky and the gear box dosen't sound very good.

Have managed to get it home by manually selecting 1st gear and driving 1-2 mph.

When put in D,R or N gear box makes the above noise.

Any thoughts would be great!!

thanks

The first thing to do is to get the ATF level checked.

If thats ok then the fluid should be drained and the sump pan checked for debris.
It sounds like a terminal problem BTW

Update

thanks for the reply.

Garage has confirmed gearbox has have failed and complete re-build required!!!! :cry:

I am being quote c £1700 for this including torque converter??:cry:

Does this sound reasonable.

cheers

Further update and question

Ok. Have had my gearbox rebuilt completely. Ouch!!! However car has been running well.

However this weekend drove away from my house (quickly) and car rev'd and then would not go past c30mph. I assume it dropped into Limp home mode which is what I did.

Tried the car the next day and runs fine generally, however in testing all is ok I have used the kick down at c60mph and car has rev'd but not accelerated.

Car then struggles to accelerate and gear are lurching. I think the car is getting stuck in a high gear as if I come to a complete stop then the car idle's but very poorly and nearly stalls.

I then have turned the car off for 10 secs and again runs fine. It will accelerate hard through to full speed as long as I dont use the kick down.

Tried kick down again and worked fine couple of times but then same problem occured again.

Oil levels all ok. Have read stuff in the forum (very interesting) on ECU's and MAF's??? and possible batteries causing issued but I am not the most competent and I am struggling to know what to think off and whether these would apply to my car.

Any help greatly appreciated.

I'd get my garage, or a local specialist, to run a diagnostic check on it.

It does sound like the MAF as this is one of the things that will re set when turning off and starting again.

Try it with it unpluged, a good test but does not always work

 

[Jerms]

Thanks for the replies. I'll search the forum re MAF's.

Out of interest if this is not working is it likely to be linked to the fact that the gearbox has just been re-built or is it just a coincidence in your view? I'm desperately looking not to have to spend any more money for a while.

Thanks

The MAF is 119 in the link,,unpluging does sometimes show that it is faulty and that the car will rev up happily, though it may run lumpy,,if it is the MAF then Ebay for a genuine Bosch one or Bosch service centers are much cheaper than from MB

Thanks again.

I have had the MAF off and it is very clean. Thanks for the "how to" on this it was very good.

I'll try running the car with it off and report back, but reckon I will try a replacement part.

Thanks again the advice is great.

Is it worth getting an indie to read out the fault codes if any are stored, before you buy one, I would hate you to buy something that you do not need, even Bosch Service center can do a good read out, and they are the ones that made the MAF

 

[Xtractorfan]

These boxes do sometimes get jerky and jumpy changing, generally caused by electrical glitches in the system, the cure is to have the box reset on a star diagnostic machine.. and it should be silky smooth again.. also as you have just had your gearbox rebuilt I would suggest you take it back to the the guys who serviced it,

as television says its the maf, air mass sensor

judging by your explanation of symptoms it sounds 100% like an airmass, but the airmass does not always log up faults and many garages dont know what range the air mass readings should be in the actual values, so be careful where you take the car as ive had many a new customer who have found us after taking car into various garages to have plugs, leads, coils, crankshaft sensors, fuel filter and pump replaced, all of which he paid for but problem still there, after looking at car for 5 mins correctly diagnosed by ourselves as airmass which was duly replaced, customer extremely happy, so just be careful where you take it,

as per the point of it looks clean,, they are not always heavily contaminated under failure,

hope this helps you

further update

thanks for all the advice and comments so ar. Thought I would update you on where I have got to.

My mercedes needed a service so took it in today and asked them to tell me what error codes are occuring.

They have said that they are not sure that the MAF is playing up but there is an error code saying that the number 4 cylinder is misfiring and may be causing the problems that I am experiencing and that they would like to fix this first and then they may get a better feel for if the MAF is working correctly, but they feel it might be.

The fix is a new coil pack?? which as they are doing the service and replacing spark plugs is only an extra 10mins work and the part (genuine merc part) is c£55.

Given the above comments I don't think I will be paying for the part if this does not fix the problem. However do faulty coils give error readings?

Any thoughts from you good folks?
thanks Nick

further update

All,

Just to close this down for me. Garage has come back to say it is no the coil as MB have advised that these hardly ever go.

They did say though that the ignition leads were causing a mis-fire and they have replaced all of these!!! and they feel this has sorted out the mis-fire.

They have confirmed that the MAF is faulty as suspected and therefore have replaced this as well without any labour costs (which is good as this takes 5 mins) and the MAF cost £95.

Car now running well. Hopefully I haven't been fleeced on the leads!!!

thanks for all the advice on this subject.

 

[Jerms]

Nothing like keeping a story going

Ok,

Kind of thought all had been put to bed but......

Car has been running fine since the service (and lead and MAF change) and then has developed a slight misfire.

Taken the car back to the garage (Tuesday 29th July) and they have diagnosed (using system and charging for this) that there are misfire codes and that one of the pipes is split. Therefore they repaired this (only charged 50% labour and diagnosis costs given the car was with them 3 weeks ago).

Car ran smoothly yesterday one way and then on the way home problems again.

Took it out in the evening and was not getting power when initially accelerating and then would sudenly "catch" and off I would fly, then when accelerating slowly it was very lumpy and jerky and if maintaining constant speed would suddenly drop a couple of hundred revs and jerk back again. (would make you feel sea sick:-?). Eventally went to pull out of junction and car just stalled!!!

Garage has just phoned this morning to say that (more fault codes although not charging for diagnosis) and that the right Lambda probe has failed, which has blown the MAF (just replaced (see previous) and they will claim under warranty for this) and that the pipe they fixed has gone again and now needs replacing as well as another pipe that is worn.

Couple of questions:
Does anyone feel that I should be paying for the above repairs? (if not why not)

Is it likely that the failed repair of the pipe may have caused this issue?

I am also more concerned now that the leads that were changed were un-necessary? Any comments?

Cheers

Thanks for keeping us all posted. Wow, you have been unlucky. I would see if they can get MB to make a major contribution under 'goodwill' or see if they will give you a sizeable discount off the bill. Sounds like they have been pretty helpful so far.

 

[Jerms]

Funny you mention asking MB for a contribution.

The work I have carried outi ncluding all my servicing is done at a independant garage. I have written to MB in the last 2 weeks saying that despite not using them I feel they have produced a bit of a duff car etc etc and asked for a general goodwill gesture to restore my faith.

They have not been very helpful at all and have basically said that as I did not buy this car through their approved dealership and that I do not get it serviced and repaired through their MB dealerships then they cannot help.

Basically if I want to pay their high prices they may consider some assistance.

If anyone has any magic idea's about hte above these woudl be dearly loved by my bank manager!!!!

 

[Jerms]

forgot to add

Sorry meant to say that I have now got the car back today. New pipes fitted and lambda sensor changed and car seems ok for the 15 min journey home so far.

Hopefully this is the end of my saga but will update if the situation changes.
