I have a D2 V8 auto and regulary tow a double horse box with 2 on board. I can honestly say that I have never been let down and towing with it is a joy.
You might be ok once you get the codes cleared. It happened to me just before Xmas, I got the codes cleared and I haven't seen the three little bugger since. Good luck.
The disco has air springs if this matters, if it is the damper bush would it not squeak weither the suspension was both at full height or normal road height? As it only squeaks at road height.
I now don't think it's the shock as when I raise the suspension and shake the disco there is no squeaking, however when I lower it back down and shake it sure enough the squeaking is back. Can anyone think of what it might be??
I have a D2 and I the rear left shock has started to squeak ( I think its the shock), it's loud enough to be heard from inside while driving as well as outside. Would this be normal if it needs replaced? Thanks.
