E 300 TD Cruise Failure 1998

Regardless of length of time on cruise,ambient or engine temperature, speed, load or any other variables I've noted, my cruise will occasionally quit. Pull the stalk back and we are back in business.

I had this problem before and after replacing the MAF.

Ideas? Techs?

Thanks in advance.

I have/had three W123 MBs that did the same thing. The cheepest fix I was taught was to remove and dissassemble the CC Actuator on the engine. On the W123 there are two contacts that sweep over two printed copper arks on a circuit board. The grease in the actuator would get onto the copper arks and onto the two contacts and cause intermittant problems. Cleaning the grease off the contacts, and shining the copper arks with a pencil eraser fixed many problems during the 650,000+ miles I put on thoes three cars.

I don't know if the actuator on your E300 is similar to the ones on the W123, but if it is, this could be one thing to check. If you do take it off the engine, be careful when you dissassemble it as you have to put everything back together again.

The W123 also has a "computer" or amplifier under the dash that often had intermittant problems. When I use to have two W123, and before all the CC crapped out, I would swap parts to figure out what was broken from one to the other. The two parts run about $300 each, so having a working CC can be expensive if both parts need repalacement.

I would hope that MB had improved things in the 14 years between my W123 and your E300.

Good Luck.

I've owned a 240D, 300D, 300sd and a 300sdl. My 300sd with a similar problem and eventually the CC died completely. The problem was fixed by replacing the cruise control unit. I found a replacement unit being advertised in the Hemmings motor guide. Unless the problem is pretty bad, I would wait until it craps out completely.

I've had cruise problems on 126 cars and corrected them as has been mentioned here. Thanks for the input.

I've been told by techs that the 210 cruise is different and has other problems/cures.

Anyone have any 210/new system experience?
