Today I noticed something strange with my car. I was at a gym studio when I turned the key and I noticed it took a few "er er"'s longer before it started. As anxious I am about my expensive toys, I let it run for 30 sec, switched it off and started again - no problems this time.
Going home from work this evening, I turned the key - glowplug icon lit up, went off a second later, and another second later I started. It cranked way longer than before. Usually it would go like "Eerr vroooomm", now it went like "Er er er er er er vroooom". No problems after starting the engine in regards to driving.
Could this be due to leaving the A/C on? The last couple of days, I haven't turned it off due to high humidity air - and surprisingly enough - this is the first time it has ever happened.
(Ambient temp around 15 celsius)
I got the car a few months ago, and have always been enabling/disabling A/C during operation, never left it on before now - neither did the previous owner (positive).
Could this be the culprit? I turned off A/C about 5 min before arriving home now, and I'll try to go out to start it and go for a short drive in a couple of hours to see if that makes a difference.
Should it be required, my car is a Volkswagen Transporter T5 (2007) 1.9L TDI
