Low oil problem

[Andyboy123]

Bought a pre reg 18 plate E220d saloon. Only 45miles on the clock. Within first 300 miles, amber low oil top up 1 litre of engine oil when next refuelling, message came on. Continued journey home, when red warning light came on, Stop No oil. Got breakdown out, they put 1 litre in, sent me on my way. Taken the car into local MB dealer ( not the dealer I purchased the car from). They checked car and Said it was 2 litres short on oil. Topped up and sent on way. Another longer journey, same issue. Car only done 1000 miles at this point. Back into garage. This time was told it's a faulty electronic dipstick, there was enough oil in it!!!!!. Changed the gauge and given the car back. Car now done 2300miles. Back in the dealership again same problem. They have had the car 7 days now and phoned to inform me the car needs a new turbo. First MB not impressed!!! Lovely motor apart from this, but experience has been ruined. Will the new turbo be the fix, fingers crossed it is.

Sorry to hear this.

I wonder where the 2L oil went though....

Burnt most in the turbo some will be in the exhaust :/

Can you reject it?

 

[Andyboy123]

dont know if I can reject it, think it's a hard process to do that, as they are willing to fix it. MB UK said the dealer will need to give me a good will gesture, as they failed to fix it each time. Only thing I would really want off them, is an extended mercedes warranty for years 3-5. Not going to have any confidence in the motor, when I eventually get it back.

I would certainly push for that extended warranty.
Burning that much oil in a short amount of miles would of been very very smokey if it’s wasn’t caught in the DPF, my concern would be that it could of considerably shortened the lifespan of that and other emissions related parts in the exhaust like NOX sensors etc.

That must have been painful for the DPF and cats...

 

[Andyboy123]

That's the worry now, the effect it's had on the rest of the engine and parts. Can only see me having more problems in the future

 

[merc85]

Cant believe it's only done 45 miles!! Fingers crossed its all sorted and the also look after you if any of the sensor's or dpf's play up.

 

[Gazwould]

Reject .

been told now by my local MB dealer who have the car, Mercedes can't get me a new turbo till February!!!!! Shocking. Going to go down the, reject the car route, it's not acceptable, Only had the car 2 months, bought it from a MB dealer 350 miles away. My local dealer has tried to fix the problem twice, unsuccessfully. Hope taking the car to my local dealer doesn't effect the process, says the dealer(selling dealer, I think) has one chance to fix, before you can reject it. Just because I taken the car to a different MB dealer for repair, shouldnt effect this??? Never rejected a car before, doubt it will be straightforward

 

[markjay]

If the car is not drivable, then presumably the supplying dealer will need to collect it on a trailer from where it is now, in order to get their 'one shot' of repair. But realistically if it's on record that it needs a new turbo and that the part won't be available before February... I doubt the supplying dealer will bother with the repair attempt.

I can only assume this is yet another engine not fitted with an oil dipstick. When and with whom exactly did this stupid trend begin ?
I will admit to being a bit behind the curve here as my 2006 AMG is the first car I have had without a dipstick.

On my particular M113 V8 engine the dipstick pipe exists with a cap on it and the engine can not be run with a dipstick in place so unless I drive around with a (very long) dipstick curled up in the boot I have to rely on the 'sensor' to tell me if my engine is about to eat itself alive due to sudden lack of oil (lets say crack in oil cooler/sump etc) , Ha ,but Petrol Pete I hear you cry, "as soon as you see the oil pressure warning light come on you will immediately stop your engine ! what fool would not ?"

I would if M113 V8 had an oil pressure lamp....that's right , for those not in the know , in their infinite wisdom Mercedes Benz chose not only to fit a big (expensive) V8 engine without a dipstick they also omitted to fit ANY way for the driver to know if it had lost all of its oil pressure at 155 (restricted) mph on the Autobahn.

And before anyone bangs on about the M113 engine being 'bullet proof' It is not . many examples have been damaged or killed by the failure of a £2 'O' ring that fails (on admittedly high mile examples) It seals the pipe that feeds the scavenging pump from the front of the saddle sump to the rear main sump and subsequently the main oil pump.

As the 'O' ring breaks up air mixed with oil is drawn into the oil pump massively reducing the pumps efficiency as the oil pressure drops. The owner of the car remains blissfully unaware of the havoc being wreaked inside his engine as the news of low oil pressure within is not (on many models) transmitted to a light on in the instrument cluster.

By the time the owner fins out it is too late.

The irony of this tale ?...just like the engine being fitted with a dipstick pipe that remains unused because it is capped off the engine actually has an oil pressure monitor take off drilled and tapped into it...that is blanked off... WTF !

Thankfully kits exist to fit either a gauge or a warning lamp. I suggest if you have an MB fitted with (any) M113 V8 variant of a certain that you have a look into it and finish the job some bright spark at MB decided not to bother with.

P.S My 15 year old £ 200 lawnmower has an oil level dipstick

 

[merc85]

I had heard of the above Pete, Have you a link to the Oil pressure gauge kit?

 

[markjay]

I....the dipstick pipe exists with a cap on it and the engine can not be run with a dipstick in place so unless I drive around with a (very long) dipstick curled up in the boot...

Not being argumentative, but that actually sounds quite sensible to me, and at any rate this is what I would have done...

 

[Andyboy123]

Yes Pete you are correct no dip stick fitted to the E class. So for the last 2000 miles of driving, the garage experts have told me, it's the dipstick not reading the oil correctl!!!. In reality, the car was using the oil and the turbo is now, let's say broken. My new car is in the garage and I have a C class courtesy car. Don't want the car back now, done 3 long journeys in it, each a 500 mile round trip. Broke down on each occasion. Can't see it just been the turbo damaged, due to this. other engine parts will have suffered. Surely I have a strong case for a replacement car or a refund.

 

[markjay]

1. Do you have finance on the car? If so, is the finance provider Mercedes Benz Finance UK?

2. Who did you buy the car from - i.e. who is the legal entity on the invoice - is it 'Mercedes Benz Retail Group' or the franchised garage name and address?

 

[Andyboy123]

No finance on the car, savings and bank loan. So I was basically a cash buyer.

It was a MB dealership I bought the car from. I just have not been using that dealership for the issues to be fixed, as it's over 300 miles away. But have been using my local MB dealer.

If the car is coming up with low oil . doesnt matter the reason. The fact is the age of the car it should not be coming up with that. get rid of it. Reject !. if it was the turbo then the oil it would be piling thru the cat and dpf(if it has one) and u would get some amount of black smoke coming out. ( u dont mention anything about black smoke therefore i doubt very very much it is the turbo. Absolutely not. Also the EGR valve would be taking a hammering with the oil. In which case say for arguments sake they change the turbo yeah all good. BUT are they also going to do the preventative maintenance. New cat, regen the dpf, remove and clean out the EGR valve and all its pipework which would also be majorly clogged with oil/soot. This car sounds like a whole world of hassle to the owner. I started a thread concerning driving your merc and oil levels. the feedback was " why do we need any of this info, stop being stupid, blah blah blah". This is an example of a faulty oil level sensor . or is it the oil level sensor ? Or is the car actually losing oil thru a defective part and in the process wreckin a whole load of other parts as markjay suggests.
