Hi all,
I have a VW Golf 1.6TDI 2011 bluemotion model with 97K miles, CR Engine. The car has been scanned with VCDS and there are no faults logged.
Recently I have been noticing an issue with my Cruise Control at lower speeds, in particular speeds below 60mph. For instance, I set the speed to 50mph on the cruise on flat ground (around 1400rpm), the cruise will then reach the set speed and keep blipping the throttle every couple of seconds or so, maintaining the speed to the point where myself and passengers feel it through the seat constantly. The 'blip' is not enough to change the speed on the speedo but enough to just feel fuel flow coming in then shutting off constantly. Turning the cruise off stops this effect...
I logged lots of data the cruise may be getting using VCDS including MAF, Boost, EGR and all were pretty close between actual/specified. After that I went into engine basic settings and did all the tests available and the car passed all of them. I then tried ABS Sensor logging to see whether the speed data was being miss-fed to the cruise. The front 2 sensors varies between each other by +/- 1kph, unsure whether this is normal but I guess so with the front wheels turning slightly?
Here is a link to a chart I compiled of my ABS Sensor logging.
I am stumped on what could be causing this aggressive attitude to the cruise. When the cruise is turned off power is smooth as expected.
Has anyone else experienced these symptoms and cured it by some other means I may have missed? If not, is there any tweak that can be done in the engine control module by way of adaptation etc to make the cruise a little more docile?
Thanks for reading!
