Dunno if it fits this discussion but...my 2014 Trax 1.4T, has an issue with the turbo... pending fault code is "turbo under-boost"... i noticed i had no passing power the other day on the highway, so it's going in for that... i also peeked around the engine bay and smelled some burning oil, checked the oil, the dipstick was dry [censored]... so i ended up adding just over 1 litre, maybe 1.25 litres tops, to bring the dipstick back up to the full mark... it's a 4.0 litre capacity engine. i get under the vehicle to take a look, and i can see there is definitely an oil leak near and around the turbo, but can't tell exactly where... it's a big mess, likely from my recent ride down the highway when i noticed the lack of passing power problem... i haven't seen any oil on the ground under the vehicle. this morning i checked the oil again, it's fine, despite the leak... i drove pretty gingerly this morning and halfway to work, i stopped and checked again, still fine. i'm going to go check again right way... So there is obviously a problem with the turbo and an oil leak, but what the consensus of being just over a litre down on oil, for who knows how long, due to the leak? i had no idiot lights or anything, and myself, i think it's "ok" but wanted to see what the consensus was from the fine folks here...
