I was given part number of 211 250 1402 by dealer for the torque converter fitted to my 2003 e320cdi. My converter is juddering like hell and I have managed to get hold of one off another E320cdi but with part number 211 250 1302. Does anyone know if there is any difference between the two and will the new one work on my car. I also have the auto gearbox from the donor car which I intend to fit as well.
Any help would be much appreciated.

Would be better to check with VIN but on a 211.026 both have been used but one is for a different serial number range than the other. Difficult to say if later one would still fit (14 02 is for higher serial numbers).

Have you had glycol tested?

Although the bulletin does not apply to Diesels, I would still check this out, especially if the vehicle was produced before 09/2003, and has a Valeo radiator.

VIN no is WDB2110262A339632 if that is any help. it is a July 2003 car but has Behr rad fitted. Torque drones and judders with classic 'glycol' symptoms so going to change box as well and do complete flush out.

DO THE FLUSH!!!! That means changing all 7+ liters of tranny fluid (not just dropping the pan). The lock up function in the torque converter lock-up solenoid is somehow not functioning well with older oil. Try flushing it out, but you may need a new torque converter. I had the same issue and no glycol contamination (had the oil checked for it twice). I tranny fluid "service" (dropping pan only) twice and it did get better each time. I finally did a flush and it removed like 99% of the droning. I still get an occasional drone when i downshift acceleration uphill, so maybe in the near future i'll need to change the converter. What's your mileage on the car? Mines at 135k

As for the torque converter part, what kind of condition is the car you are removing it from? You may just be better off getting a new part as the used part maybe in the same condition yours is in and may have to replace it again in the future. Think about how long you will keep your car, how much you risk to spend to replace again possibly later on, and the chances of putting the used converter in your car and still having the droning noise. As for if the used part will fit your tranny, you may first want to check if you have the same transmissions. If it is different, i think there is a high chance that it wont fit. GOOD LUCK anyways!

Thanks for reply. Car has 160k on it and donor car had 50k. My plan is to fit the new converter and get old one reconditioned for any future failures. As I have bought the whole transmission and torque converter its def going to fit but I am worried about software issues. Does gearbox have control unit on it?

Before replacing parts, I would have the dealer, an independent or anyone with SDS access deactivate the torque converter to verify the concern is no longer reproducible and as such is your problem. As recommended flushing the ATF may suffice, improvement should become noticeable after about 60-120 miles of driving. If you want I can send copies of DTB 27.20/78a and 27.55/50g (glycol contamination) to reference, PM your email address.

Enter VIN here http://old.mbclub.ru/mb/vin/?lng=eng – your vehicle is equipped with transmission # 601073. EPC shows TC part # 2112501302 up to transmission # 717346, 2112501402 as of 717347. Not certain what the difference is and EPC does not indicate 1402 replaces 1302 therefore 1302 should be fine if replacement is needed.

i had my transmission, cooling lines, and radiator replaced under Starmark warranty because of glycol contamination.

i still get shutters at low speed though sometimes. i haven't tried on C mode. last night was pretty bad in a parking lot and it was loud too. idk if they changed the torque converter, would they have? also, i would think they had flushed out all the tranny fluid when they replaced the tranny.

This build date of this car is 26/06/2003, that means it is in the window that can be affected by the glycol leak. You are referring to the US bulletin which does not have CDIs because they were not sold in the US before the radiator was changed but they were sold in Europe and elsewhere. Your list does not have a 270CDI either.

Because of this confusion, it would be useful to add location and car info to the profile.

Diesel Benz

Where did you read it has a Behr radiator? Most likely from the intercooler box. European experts claim no 320 CDI has had a Behr radiator (which does not mean all would be faulty, then again, some have experienced glycol leak with the modified Valeo radiator too, although after high mileage). Can you double-check the radiator part number?

Diesel Benz

Have you seen hot the torque converter looks like? It would be 10 times more expensive to have it fixed than buying a new part and even then it would not be built the same way as originally.

Electronic Transmission Control unit is at the engine bay. But you can have the SW updated.

Interesting. I tried my VIN and got. My car was purchased new at the dealer and the VIN has been valid for all warranty.

Perhaps it just isn't listed in the local of the domain.

1) VIN was misspelled in the request form;
2) VIN was erroneously read from vehicle body or documents;
3) VIN is not of an original vehicle and was forged by criminals;
4) The vehicle was produced in late 2005 or 2006, and is not included yet in our database


FYI on repairing a torque coverter I always buy new. The weld is extremely precise in assembly and balance is critical.

Repairs by other than a percision shop would be very risky at best. Just my opinion of course.

MBtech1098

You are correct, our list does not contain diesels, because the 211 diesel was not released in the US market till 2005.

konigstiger

Russian site is not always reliable for MBUSA it is common for codes to be shown as unknown and occasionally VIN is not recognized.

OK,, thanks for the info. I haven't confirmed but I think I have the Valeo MFG date 8/02 on our 03 E500 but so far it has held up. Warranty runs out this month.

Test drove new E350 and considering one but given the retirement account has taken a "small" hit over the last 24 months a new car is delayed.

Look at your Service statement. If they changed the tranny, they must've changed the torque converter. The malfunction of lock-up function in the torque converter was the reason why you were getting the droning noise (as i've read). I've also heard cases where the radiator, lines, and only the torque converter were changed and that was all that was needed.

On a side note, these radiators have failed at around 40,000 miles. I do have the Valeo radiator, but still no glycol contamination at 135k miles. I haven't heard the radiator fail at a mileage higher than 60,000, so i'm doubting the OP has glycol. Do you guys agree?

gaazmon

thanks mercfive.

+1 on the high mileage thing. if his miles are in km, then he should have a little over 99,000 miles. i would also wonder why it would fail at such high mileage. mine failed at a little over 47,000 miles.

OP, you should still probably get a glycol test and see how it comes out.
