If your radiator is not leaking (or loosing fluid) then you do not need a new one. Find a different mechanic.

 

I confronted the mechanic about the 900$ radiator and he said it was 511$ because of warranty. Then i asked him why he thought it was the radiator and he couldn't give me an explanation. I took my car out of the shop and brought it to a new mechanic, and he'll get to it in a day. Hopefully this one will be more trustworthy. Thank you all for your help!

 

On your tire pressure monitoring problem, there is a test that you can do and it will tell you which tire it thinks is the problem. You can also determine if you have a faulty sensor (like I do). If your tires are properly inflated, it may be a bad sensor.

The TPMS check is in your manual and also somewhere on this forum. Just search for TPMS and you should find it. Good luck!

 

Keep up posted...good luck!

 

Any updates derian to the p0300 and p0305? I just got these codes for the first time ever on my 06 h3 with 63500 miles. I had just recently cleaned the throttle body and replaced plugs, so for now i switched coil pack 5 with 4 and cleared the codes. Hasnt came back yet. I bought an additonal coil pack just in case.
