'91 W126 Intermittent Anti-Theft Alarm Problem
The alarm on my '91 W126 will activate without meeting any of normal criteria ... when it is rock solid, stable, etc. Only does this about one per 10 lockings. No pattern.
I read in one of the threats on a 1987 126 the cause was suspected to have been the tow sensor ... I do have a box with wiring and a long aluminum tube on the left rear wheel well side (in trunk).
