My mk5 gti (stage 1 APPR) did this two times yesterday upon startup. The second time the battery light came on. Just put a new battery in it less than 6 months ago, but my mechanic did instal defoulers bc my O2sensors kept going out. Could it be the alternator or maybe a...
08 mk5 GTI- I got the O2 sensor code coming up, fuel measuring system malfunction (bank 1) O2 sensor positive current control etc. here are the codes
04243 08598 08759 08825
It's a stage 1 APR tuned and is at 111k miles
Please help! Thank you so much!
This helps! Would the smoke test from last time show this? The same code is pooping up so I can assume its the dipstick holder? But its such a small area to set off that code...we are checking the wastegate and the n75 sensor as well
Last time he did a smoke test and said it was <1 psi of air that was coming from the dipstick which needs to be replaced (the suction is gone). Could that possibly be it? Can you explain what you mean by "They are all Lambda based which is reported by the B1S1 O2 sensor that was replaced?"

Turbo underboost is a shadow code for the O2 sensor (from my mechanic) but that was just done in January- brand new. Any ideas what this could be/ why it’s happening. He asked me about my CAT which has never been replaced. The last time this CEL came on was almost 3 weeks ago, I cleared it and...

I guess you will find out soon enough, some of those Dtc need two drive cycles before they turn the Mil on.
Welp, it just came back on (08825- Intake Air System). Its the only code. Mechanic thinks it may be intake manifold, vacuume seal or boost leak :(
