Have you got vag-com to scan for codes, Is your engine management light on ?

Mines used to do this when it blew a fuse under the steering wheel

 

[danarmstrong]

yer plugged it in but only code showin is SAI which is bollucks lol, what fuse u mean?
cheers

 

[alexbradford]

The fuse box under the steering wheel, Think it was fuse 8? Its a red fuse anyhow.

Does anyone kno if the lambda sensor could cause me problems? Coz I decated it last week and there are two lambda sensors, one before Nd one after the cat so I unplugged the one after the cat. Just wondering if that could cause me problems,

 

[seatcupramad23]

if there no relative codes pointing to the cat den m shudnt tink so had my last lc de cated no problems, are u running standard bosch recirc valve ? n might wana give n75 a check had the same issue last year turned out n75 was nackered hope this helps

 

[danarmstrong]

Well I will give the lambda a go n just plug it in n see how it goe, can't do any harm can it, got a forge recirc valve, ain't checked the n75, was hoping to get time to bypass all the n75 and n249

Well if you remove a lambda then the engine wouldnt be running right? Most people get the 2nd lambda mapped out. Did you check the fuse I told you about?

 

[danarmstrong]

Yer mate checked that fuse, all fuses are mint, gonna try plugging in the lambda sensor n reset the brain n see how it goes otherwise Fuk knows lol. It's had a jabba stage 2 custom map so that should be mapped out
