Hello. I have a Seat Toledo 20vt with engine code AUQ. Totally stock except a custom remap to 210 theoretical hp. I post on the Leon section because more members have it than the Toledo but still the engine is exactly the same. Suddenly, while driving the car did a small jump and the tcs light came on. Im no stranger to this so i checked the fuse number 43 which is responsible for maf and o2 as i know. The fuse was blown. I changed the fuse but after some miles it got blown again. And again. Maf worked fine between the fuses been blown. Now, even just turning the ignition to on blows the fuse. What can be the issue? Is the maf faulty? The o2? A short circuit somewhere? A relay? Thanks guys
