Hey guys I just joined the forum because I picked up an '11 335d.
I would love to get a tune on it and limited slip, already talked to tuning company.
On my way to work yesterday I got a SES light. Car's driving fine, so I'm guessing its some sort of emissions balogney. My question is what will happen if I have such problems in the future after the tune? Will BMW still warranty my car?
