IMO if it was some bad engineering issue it should have been more common than few cases, the question is if all those who experienced this symptom have respected ALL the instructions from the owner's handbook for towing, cos that's important like any other builder's recommendation, as i said about the ABS system's missbehaviour with bigger wheels there are conditions to be upheld for the vehicle to act as it was conceived and that implies to be as close to standard as possible, even bigger wheels than standard or different pressures can affect any system's behaviour as long as it was ''calibrated'' from factory for the standard equipment as in the book, relevant would be to make a statistic of how many cases of such towing issues happened on standard equipped D2s and how many on those with lifts, bigger tyres, etc other that standard, maybe what's in the following pages was not completely repected(or not even known by some owners) , watching only this particuar case where mr. Johnlad has 34 pressure on rear while 46 is recommended by the vehicle's builder for towing and 38 for normal operating conditions.... and who knows what else in other cases on the web?
important note from the book:
"The suspension is designed to cope with a
heavy trailer load without upsetting the balance
or feel of the vehicle."
There is none so blind as those that refuse to see!
On James Martins original posts he comments a brand new Discovery 2 has this problem, you would expect a new Disco to be fitted with all the correct standard items from the factory.
Also far from being an isolated few, it became such a concern that tests were carried out at a road research lab(read link posted above), who although couldnt identify a specific fault at that time, that it was well known that there is a problem.
Ive ordered a set of coils now and will fit and report back on my findings, I know its a retrograde step but the car is unuseable as it is.
And Land rover themselves became aware of it and issued a further bullitin regarding towing and tow bars
