For about a week my Wagon R+ (diesel engine) has been whistling from about 1500 revolutions/minute pretty tall. The first two days I pushed it to the extremely cold weather, but yesterday I drove a distance of approx. 250km at a distance (engine was certainly quite warm) and it still whistled. It is not unbearable but annoying. Besides, I have since then a radius of approx. 50-70km reduced (reichsweichte) pr o Tank charge. Furthermore, I have the feeling that the response of the engine has deteriorated when giving gas. The Wagon R+ is the series of 2004 and has now almost 90000km (600km below). I fear that it is the turbocharger. Just because I had filled out some time ago (about 3 months and 4500km) of equipped petrol (fortunately there were still about 10 liters of diesel in it) and drove 15km home. The workshop pumped the tank and the whole tank was pumped away. spraying system cleaned (as well as a few seals exchanged and the petrol filter replaced), but who knows what everything was pulled in with pleasure (or does the turbocharger have to do with it?). Otherwise, who runs Wagon R+ super (purchased it first hand at the dealer in May). Does anyone happen to still give Suzuki warranty for how long and if this problem occurs more often at Suzuki? Would I really be happy about your opinions. I’m a bit desperate, because the turbocharger is certainly not T cheap and I haven’t paid off the car with my father yet… P.S. If it helps, TÜV just got it about 4 weeks ago and he has to get the workshop the days anyway because of the 90,000 inspection.
