Help with fault codes please
« on: 31 July 2020, 14:18 »
Done a 300 miles round trip yesterday, car didn’t skip a beat all the way and when I got home I stopped to get food and when I got back in the car the engine light came on in the dash  :shocked: I plugged in my obdeleven dongle and got the following error codes, car drives the same to me and I’m not noticing any strange noises or lack of performance

What should I be checking? i cleared the faults and they never came back, haven't driven the car today but will report back if it behaves differently

the mk6 is a big leap up in technology from the mk3 ive been driving for 10 yrs :grin:

The original part number 06H906517h (n80 purge valve) has been superseded by a revised part which is completely different! I have managed to source the original part online so all good :nerd:

I am noticing some hissing when accelerating and some petrol fumes when getting stuff out of the boot so hopefully this will fix that, drives nice still tho :wink: getting 42mpg on moterway runs

Ive had the code once but only when the car had sat a few months unused so i have my fingers crossed its okand had just stuck as not as easy to change on these as older cars unless you want to cut and join pipes.

Snoopy I am hoping to cut & join pipes as a cheap DIY, seen a YouTube video on it  :whistle:but am considering just getting the garage to replace it at the same time as the chain tensioner, only problem is a 2 week wait as the garage is always busy, I've noticed today the car amusing more fuel on short town runs

Think this is the one from my YouTube history I watched on how to do it without cutting the pipes for the n80 valve

just to update, i managed to change the purge valve and hoses, what a ballache that was!

still got a PO299 turbo underboost fault code but i am hoping that maybe due to my flexi downpipe needing changing, earliest i can get that done is 10th september :undecided: hope that sorts it
