Hi Everyone,
I've recently acquired a 2022 CLA 220D with 18k on the clock, I've since added @2k.
I've found that sporadically, probably every dozen commutes (Usually 15miles) my fuel economy plummets from the normal 57ish mpg down to 29-36 mpg.
When the commute ends, the fan's going ten to the dozen and the engine area just smells hot with noticeable heat coming from the wheel areas.
Steering isn't pulling so unlikely to be brakes binding. No obvious warning lights etc.
Sytner have had the car back and said nothing wrong.
Next commute is normal with fuel eco back to normal. I'm running the car in comfort mode, haven't used any other apart from eco on a 250 mile journey to see if there was any difference.
Any ideas?
TIA
Phill
