Hello Jason thankyou for reply,No i dont have a way, and im not tech savvy at all.I had a guy looking after the 6 cylinder z3, but hes seems to be out of touch now.
To be honest with you, if you have no way of reading codes or carrying out other basic diagnostics, we might struggle to identify the cause.
There are a number of common parts that can cause this issue but diagnostics is required to know which one is the culprit.
If one of your lights is the tyre pressure light, you could just be looking at getting one of the wheel speed sensors replaced.
If you have codes relating to the pressure sensors on the brake system, they could be the cause.
The DSC module itself can also fail. This would require sending it off for a refurb.
I had the same issue weeks back; 3 lights but the car would go into limp mode. This turned out to be a communication issue between the DME and throttle body.
If you don't intend to carry out the work or perform the diagnostics yourself I would probably suggest that you should be looking for a skilled independent mechanic to troubleshoot this one.
