I've been floating around the webs and this site trying to problem solve a p0299 issue I am having. A few months back I had my car in for inspection. It had a SAI CEL and my mechanic traced the issue to cracked PCV hardware. He ended up replacing most if not all of the PCV plastic bits and...

I just replaced my old worn out diverter valve with a 710N. Now around 2,000-2,500 RPM I get this really annoying groaning noise that will go away if I let off the throttle or accelerate. I know this has been discussed and I've read every thread I can find on the subject. But, they all kind of...

our 2001 passat was running very lean, its running at 25% on the trim, O2 sensor is chalk white... I found the crank case breather pipe was broken right where it enters the case under the intake manifold. That didn't make any changes so I looked around and found the diaphragm was torn on the...

I would like some help to identify a few parts. I want to replace the PCV valve, diverter valve, & coolant temp sensor on my 04 GLS 1.8T. I've done some searching and read a few different threads already. I've learned there's 2 different (upper & lower) PCV valves, and 2 different types...

1.8t 2002 Wagon - ~150k miles I've noticed a strange (to me) sound coming from the car when I accelerate, especially uphill - usually when the RPMs hit around 18 and in the mid 20s. It's a slight metallic pinging/fluttering sound. I can't decide if it is the bicycle-card-in-spokes sound that is...

I just replaced my seized ko3 with a ko4 as a first step to what I'm sure will be a long line of modifications to my 01'. First thing I noticed was the intermittent boosting I was experiencing. If I eased into the throttle it will be fine until I hit about 2500-3000 rpms then it start bucking...

Couple questions concerning power gains I just got a 2000 1.8t. There are a few things i want to do to it but i have some questions. I just bought a new DV. I am going to eventually get a High flow 2.5" CAT, a 2.5" downpipe, and then a chip. I would be running the CAT and downpipe to the rest...

Hi All, I've got two error codes that are persistant. The underboost code will be fixed (I HOPE) when I replace the diverter valve which is currently sitting in my trunk. But I'm getting a persistently intermittent P0303. Here's whats going on: Some mornings, I can start the car and get a...

Interested in doing a double project with a front mounted intercooler and relocating the DV to the cool side of the engine bay. My question is, while remaining on the stock turbo for some time will i encounter a negative result when getting a front mounted intercooler?:crazy: Thanks

Hello, Ive tried to research this problem but cannot find it anywhere. probably due to the fact that i have no idea what it is. that being said... I have a 99 passat 1.8T AEB. When I floor the car from both a stand still and cruising speed the car cuts in and out violently and makes some loud...

Hello. i have notice a vacuum hose just dangling by the diverter valve. it runs straight to the intake. I assume this should be plugged into the top of the dv? so i put it together and zip tied it for the time being. however once i did this when i floored the car it would cut in and out and make...
