Would the N75 error below put my car into limp mode? I recently got my car chipped and have an appointment at audi in a day or two to get a brake problem fixed.. do you think they will replace it without questioning(I will put my car in stock mode but if they really look they will be able to tell its chipped)


18010 - Power Supply Terminal 30: Voltage too Low
P1602 - 35-10 - - - Intermittent
17956 - Boost Pressure Regulation Valve (N75): Open Circuit
P1548 - 35-00 - -

 

I would have the codes cleared (not by the $tealer) and see if they come back. I think I had those same codes after i got chipped and cleared them and they never came back. You are likely to throw a code or 2 while your ecu is adapting to the new chip during the first few weeks. Sometimes certain perameters are exceeded orbecomeout of whack until your ecu fully adapts which is usually accompanied by soft limp mode (no CEL and comes out of limp simply by restarting the engine.)
Also for best performance change your plugs to NGK Bkr6e (copper)gapped at .028 since you are chipped now. Need changine more often than irrid and plat but perform way better and reduces your chances of detonation which worst case= bye bye engine.

 

good to know about the plugs, so with just a 91 oct chip these plugs are the best option?

 

Yup. I mean plat or irridium isnt gunna kill your engine, but in high boosthigh heat,copper performs best. Do a search on copper plugs for more info. Like i said they dont last as long as platinm or irridi and need changed every 10k miles or less.... But certainly perform better.

 

Iridium ik22's come gapped at .028... I got them because I got my car chipped. The important thing when you add horsepower is to go a step colder with your plugs. I havent heard anyone blowing their engine because of using iridiums, so not having to change them as often seems a good reason to buy them for anyone in the market for new plugs. I have only heard good things about the ik22's ... same goes for the ngk's though

 

yup like i said they arent gunna kill your engine, but physics says copper is best for high heat which = forced/compressed air. You dont need to go a heat range cooler than stock unless you upgrade to a K04 or anything that runs more than 20 psi consistantly. But again, its not gunna kill your engine, but i guarantee your plugs will be fouled up real quick in colder weather due to not being able to get heated up enough. With one heat range cooler than stock durng a real cold day (even with a chip) you may even notice misfires until the engine warms up.
