Hi all, bought a 2003 Gen3 DiD SWB AT (with M-ASTC) with close-on 224000km beginning of this month (almost on 225000km now). Car is in nice original condition and going well. Took it to Mitspro for a major service and check-up and they gave it a clean bill of health.
This post is about two problems which seem to be related, so in order of appearance, they are:
1. The speedo goes "haywire" (i.e. jumping around) after extended periods of stop/start driving. This of course renders the cruise control useless which is rather frustrating. Practical example - went to De Wildt 4x4 today, no problem on the way there (75km trip) but heading home after off road driving it did its thing. As a side note, the jumping is directly proportional to throttle input.
2. Got a flashing "N" light this afternoon, with the box going into limp mode (luckily close to home). Switched the car off and on and problem was gone for a few kilos. Took a drive later and no problem. A/T Temp light did not come on. Did not get any warning lights or flashes during off road driving, car performed very well.
After doing some reading online I get a feeling the problem might be (one of the) the speed sensor(s) on the box (known to cause the N flash) which might explain the the sporadically erratic speedo. I'm not suspecting a problem with the box itself as it performs faultlessly (i.e. smooth and responsive) otherwise.
Would greatly appreciate some insight/input in this regard
