Hi all

 

I have a fault code on my 2007 Octavia vrs tfsi P0171, 008567 Bank1 system too lean off idle.  I have recently changed the Evap Canister as a fault code relating to that came on at the same time (which is now sorted) I then changed the PCV valve and also the cam follower and still the fault came back visually inspected all the pipes looked fine, had a smoke test done and everything is fine no leaks.  I'm running out of ideas and patience. My intake system is EVOMS which was already on the car when I got it so if I'm to do the Maf sensor I'm guessing its not as easy as going to the dealers, and I cant find this anywhere.
Also been told to check fuel pump G6 only fuel pump I know of is the hpfp is that right?

 

I have searched the net and found that mostly what I have listed above is what people suggest and cant find a thread where this issue has been resolved.

 

Thanks for any replys

futher updates to this had VCDS hooked up fault codes p2177, p0300 & p0301. Blocks 002 seemed fine, 030 sensor 2 fluctuating as it should sensor 1 not fluctuating just sat at 00111. Block 032 idle was between -1 & -4% partial was at 25% cleared codes went back into block 032 with car running no reading for partial and it crept up from 0% to 5.7% then sat between 4-5% Block 030 sensor 2 working sensor 1 was mainly sitting at 00111 ocasionaly fluctuating.

Took spark plugs out and can saftley say its running rich coil number 3 and plug 3 had oil on it, done a compression test and was spot on put plugs and coils back in then took the pack off the coils 1 at a time and they engine changed note as it should each time.

for anyone following and because I cant find any solved threads on this, Think I now may have solved the problem or the garage rather injector 1 looks to be stuck closed.. will find out tomorrow when that gets replaced £300 lighter however

Since ian89 hasn't visited briskoda since 21st September 2018 you probably won't get a reply
