I have an 85' EURO 300D (Non Turbo). Is the trap oxidizer installed in my car or only in US Versions? If I do have this, where is it located? Can I just take it out without affecting engine performance? I live in the Philippines and we can do away with catalytic converters.

I doubt that your car has one.

Francis,
The trap oxidizer was on the 124 diesels in 86 to 88. If your car is an 85 it should be a w123 car. If there are any cars still out there with the trap oxidizer intact, MB will remove it at no charge. |

All 87 300D US model had the trap oxidizer to begin with. The recall removes the trap oxidizer and put a silver pipe where the trap oxidizer was. The entire exhaust system is to be replaced as part of the recall. In every recall case I saw, the turbo was replaced too. The silver pipe is found along side next to the engine, almost the same level as the engine head, near the battery. If you see that area has a big fat round muffler-like object, you still have the trap oxidizer. In 1985, California was the only state to have the trap oxidizer and only on the 617 engine. Modification for the 85 Calif (w123 and w126 body) is different from the 87 above.
Note: I saw some people purchased the silver pipe and replaced the trap oxidizer (1987) themselves to increase performance. That is only half of the modification, you need the new exhaust system to meet the smog requirements. In this case, I do not think MB will touch that car at all.

I recently bought my 87 300TDT, and brought the VIN to the dealer to have a history run (I already knew it needed it, but went through the paces). They will tell you if the recall has been accomplished, or if any others are outstanding. It also gives paint coses, delivery dates, etc. Recalls are no charge and the trap Oxidizer replacement takes about 1 and 1/2 days. I'm dropping it off March 7 and I can post a status when I get it back if any one is interested.

Well, the recall has now been completed and everything was and is fine.
For those of you asking how to tell if it has been done, the trap was as very bulbous, sheet metal shrouded vessel, on the passenger side of the engine. It took up all the space on the top side between the valve cover and the air filter. At removal, it is replaced with a very svelt, streamlined pipe that is covered with a metallic foil insulator. The turbo and exhaust manifold is non easily visible. As Benzmac had said earlier in this thread, the entire exhaust system, including the muffler is replaced at no charge! Benzmac - I do have one question, the turbo was not changed on my car! The dealer said it was in good working order, had no damage, and did not need to be replaced. I can attest to the fact that it is working fine, but at 150,000 miles, it sure would have been nice to get a new one. Do you have any comment or advice? I guess I could have waited for it to fail, and then gotten it all for free, but reliability is important, so I did not wait till failure.

Here is a link that shows a pretty good picture of the trap oxidizer, both before and after. http://www.dhc.net/~pmhack/mercedes/trapoxr.HTM

The recall campaign, #96-1121, stated that if the Turbocharger is damaged due to caused by the Trap Oxidizer, it will be replaced free of charge. Your recall is final. The whole system is warrenty for 1 year. If your turbo fails in the future, you have to pay for it unless you can prove that the damage is caused by the T.O. as stated in 96-1121. David David |

I just got off the phone with MB customer service and the trap oxidizer is still due to be replaced on my '87 300TD and the recall is still open.
She pointed out that the trap oxidizer failure and the subsequent turbo failure are simultaneous and once this recall is completed it is doubtfull that any turbo failure could be linked to the TO. I'll let you know how the car performs after my appointment Wed. |

What was the trap oxydizer supposed to do? If it can be removed (at MB's expense)it sounds like it didn't do anything but cause trouble.

We'll after two days of confusion at the MB Manhattan my assistant service manager seems certain that the correct parts are now on order to complete the TO replacement. I'll have to bring it back on Monday and try again. This may be a side affect of having more cars to work on then you can shake a stick at. You should see this place!
I attempted to avoid this problem by specifically asking for the TO recall (known at MB as a campaign) when I made the appointment two weeks ago, but it appears that no work on anything (like ordering the parts) happens before the vehicle arrives. I even tried to order the parts myself by asking for the trap recall by name at the parts dept. and giving them my VIN number. They were sure they ordered everything that I needed. Hmmm, maybe I'm going get a new turbo. That would surely explain my prominant position in the sloooow lane. |

Trap Oxidizer complete at MB's expense. Don't want to jump to conclusions, but it was noticably perkier on the drive home from the dealer. I'll give it a real test on the weekend.
One concern was that they didn't perform a boost test, but simply inspected the turbo and TO for indications of damage. Is that part of the campaign and should have been done or not necessarily? ------------------ -Mike '87 300TD Turbo |

Finally got a real roll test in today. Took the kids to the zoo via the Cross Bronx expressway. I am happy to report that the trap oxidizer replacment has fixed my severe low power problem. And I'm grinning.
I'm by no means the quickest on the road, but I won't be holding anyone back from now on. As a further note on the MB campaign, I got the official letter from MB USA after registering as the owner of record. Not bad service at all. ------------------ -Mike '87 300TD Turbo |

Have you guys noticed any changes in exhaust
notes such as more growling noise in 2500 rpm range after TO removal? ------------------ 87 300D 161k 00 S2000 87 944S 89k 99 Yam M/C R6 |
