Based on the VAG Com it first threw up the lambarda sensor which I changed then it gave me codes which related to Coils 1 and 2 which i also replaced.

Now I am getting the code 17705 - 'pressure drop between turbo and throttle valve p1297 upper limit reached'

I then cleaned out the throttle body but still have the same issue. The car idles a little rough and it seems to be drinking alot of fuel. I have also changed the coolant temp sensor and spark plugs.

Can anyone help? I am running out of ideas and cash
Hey Ifty,
I get the P1296 code as well after just having the Coolant Temp Sensor replaced on warranty. Engine still never reaches operating temp and fans come on at start up. Pretty sure that replacing my thermostat will fix it - I'll be sure to let you know but that might be where you want to start. Hope that helps.

I get coil packs for my car at ECS tuning. I can't give you the link because apparently I need five posts, but a quick google will show you the site.

Anybody ever get the "Gear Recognition Signal" DTC? There is no corresponding code in the tranny, it's seems a lot of people get this but have no idea what is throwing it.

Been a while but I thought I'd update. I replaced the thermostat myself (not a tough job really with the amazing write ups and tutorials here, just takes a while to do, but then I'm a slow methodical worker). Fixed the problem and no codes ever since.
