_LM46 Posted August 10, 2020 Share Posted August 10, 2020 It’s been fairly hot recently and my Glanza has felt less powerful than usual, the temp gauge creeps up to about the middle and ends up staying there but the car feels slower than usual and the turbo doesn’t seem to come on as quickly as it usually does and when it does it doesn’t fully boost to the 1.2 bar it’s set up to, it gets to about 1 bar and doesn’t go any further up, just wondering if anyone can help me understand this better so that I can fix the car, I’ve had no check engine light when this happens, the car just runs hotter and ends up feeling slower, it has oil, coolant, the fan is working as it should I don’t understand what it could be, thanks Quote Link to post Share on other sites

Have these problems been fixed? Have you modified or changed anything recently? Firstly do a diagnostic check to see if there are any codes. Also check the obvious thing like boost pipes and vacuum hoses for damage / leaks / clamp tightness / intercooler damage / blocked air filter. When you say it "runs hotter" do you mean that the coolant temp. gauge moves above half way when driving hard? Also if you take the car for a drive early in the morning when the air is cold does it boost normally? Edited August 11, 2020 by Claymore Quote Link to post Share on other sites
Sam44 Posted August 11, 2020 Share Posted August 11, 2020 (edited) Seasonal changes my friend. What's your spec. If the the car has been mapped in winter you will normaly notice a biggish change in power levels. Also at these temps altitude is another factor. You should notice the car is using less fuel also. Be warned this time of year is a killer stay away from high speed runs the coolant system quickly becomes inefficient Edited August 11, 2020 by Sam44 Quote Link to post Share on other sites
