Hi all,
My Golf Mk7 GT TDI Bluemotion (150bhp) has been exhibiting this very intermittent bucking whilst driving under light throttle (between 1500-2000rpm). It had also started doing it when moving off from a standstill which is a bit worrying with the fear of the vehicle behind rear ending you.
I've tried many injector cleaners through the tank, new air filters and also two fuel filters and nothing improved it.
I have VCDS and it reports no faults. I even tried monitoring the fuel injectors and from what I can tell they appear to be operating within their tolerances.
The car starts fine, returns excellent fuel economy and pulls like a train on hard throttle to the red line. Mileage is around 82,000. The issue has been there for several thousand miles.
Most recently I considered swapping out the MAF as it was comparably the cheapest option to taking it into a garage to start changing more expensive components in order to troubleshoot. However I decided for the sake of £10 to give cleaning it a go, and tried this Luqui Moly MAF cleaner. I did just that and to my surprise it seemed to have resolve the bucking between 1500-2000 and made it more responsive to drive. However a week later the problem has returned but now showing itself intermittently between 4000-5000rpm.
I know I might be stating the obvious here but could I just have a dodgy MAF sensor here or just is this masking something more serious?
