the easiest way to find out EXACTLY whats wrong is to ask an AUDI DEALER for a diagnostic check for your car,they have the fault codes and the book that tells them what parts need replacing,if any.the glow plugs are in no way connected to the warning triangle/abs,so you have at least two problems......the cost of diagnostics is about $50,cheap if you buy/fit any parts required.
UNLESS YOU HAVE A LIST OF ALL THE FAULT CODES AND WHAT THEY MEAN.......you could fit bits that are not needed.

u will have to remove the radio partially to find out its parts number, then call audi customer support give them that number and they will give u the code.

Check wire harness between driver door and body for broken wires.Wire harness bends , when door opens and closes so it may brake the wire or two inside harness.

Look at this site, it has detailed instructions for various Audi radios (assuming you have the code)

if you dont have it you will need to call the dealer.
Or remove the stereo and get the make and model and search online.
Its going to cost if the dealer won't give it to you for free

You would be better off to pay $16.00 for a haynes repair manual for that car, it gives a step by step procedure, It would take a lot to tell you on here. If you are going to change the strut springs to the new ones, you need a spring compressor, and if you don't know what your doing and be very careful, and the spring slips and hits you, you will be severelly injured.

HI,THE REASON YOU ARE GETTING AN ERROR MESSAGE IS BECAUSE THE MECHANISM IS FAULTY,YOU WILL HAVE TO HAVE IT REPAIRED,ANDY

oil type is either 5W-30W or 10W-30W depending how cold your climate is, as far as having the car properly taken care of, the Audi dealer is the best option, they have all the proper tools and service info needed to keep the car in top running condition.
