HI

My mechanic has told me that I need a new throttle valve actuator for my 1995 E320 wagon. I have searched used parts web sites but they keep asking me if I want it with or without ASR. My mechanic does not know what ASR is. How do I know if I want the one with or the one without ASR?

Thx

ASR cars have an "ASR" warning light below the instruments, and have a switch with a picture of a snow tire above the climate control buttons. You can also look up your option codes by entering your VIN number here: http://old.mbclub.ru/mb/vin/?lng=eng ASR is option code 471.

To add to Deans info..
On that chassis , the ASR Lamp is next to [ left of] the Check Engine lamp...turn on the key and it will light up..there is also a big yellow triangle with an "!" mark in the middle of the speedo..that is ASR warning...
You have to use ASR designated parts on ASR systems. [ unfortunately]

This could be a great mechanic but it sounds a bit exciting to have your throttle actuator replaced by a mechanic who doesn't know what ASR is. ASR has helped to put many children of MB mechanics through college - expensive, private northeastern schools.

Thank you, that has been really helpful.

One other question. I have found a replacement part. The vendor say that the part number is 000 141 57 25 from the parts book but doesn't seem to know anything about ASR either. Does anyone have access to a parts book and could confirm whether this the throttle valve actuator without ASR that I need?

Thx

That is for w/o ASR.

Do you have ASR?????

I'll meet deanyel halfway on this one.

Yes, a mechanic who wants to replace a throttle actuator ($$$), but doesn't even know what ASR is should raise a few red flags.

As far as earning college money? No way. Diagnosing ASR issues on older MB's accurately, is very time consuming. If I had to depend on ASR money to send my kids to college they'd both be attending Community College.

On the other hand, whomever pockets the mark-up on the price of the parts is definitely in good shape.

Joke, but ASR has undoubtedly created a lot of billable hours that don't exist on non-ASR cars, both diagnostic and finding and fixing things to which non-ASR cars aren't that senstive.
