Was having a bit of an "issue" with it hesitating under part throttle and feeling a little down on power. This was going on for a couple of weeks so did some searching on here and lambda sensor kept popping up. Ordered a new one off H-Tune last week then the day it arrived my check engine light came on... but the hesitation stopped! I tried pulling a fault code but came back with nothing! So, finally got around to fitting the new sensor last night, what a bitch of a job! Sorted it right out though, no more warning light, no hesitation and it feels faster than it has for a while! Forgot to take any pics as it was a right royal pain in the a*s....
