So i was driving my 2009 ralliart kind of hard today (well just every once in a while ill give it about 3/4 throttle never full) and when i was just driving normal i noticed that "tarmac" on the screen was flashing? So i looked up in the manual and it says that sometimes under hard driving it will do this. But, my issue here is about 4 months ago i got that "serviced required" light in yellow. i later found out that it was because i had 215 tires in the front and 225 tires in the back. so i got that fixed and it never happened again. should i worry/tell the dealer or just wait it out? my main concerin is I'm about to put coilovers on my car so i don't want them to say "oh well your acd pump blew up because of your car being lowered" idk if they can even say that but hey who knows? Thanks in advanced.

 

btw it wasn't cold today, mid 80s

 

I'd take it to the dealer. You might have damaged the acd with the tires, and now it is overheating to easily.

 

Yeah I think that's best. Thank you.

 

but i wouldn't tell them that you had staggered wheels on the car. Just play dumb.
