  2. MKV GTI
    OK, have an 09 GTI MKV w/TSI 2.0...CEL came on & idling really rough. Went & had them throw the tool on to see what codes I was throwing & came up w/12 of them! Just changed the plugs about 10k ago & the guy suggested replacing the Crankshaft Position Sensor. I'm pretty mechanically inclined &...

    01 GTI 1.8t 106k Oil pressure sensor was going off randomly but not frequently (prob 2x in a couple weeks). I had a CEL light on for a suck open thermostat.. so i went ahead and got the oil pressure sensor with the thermostat and did them both last night. Now with the new part in the car will...
  4. MKIV GTI
    I have a quick question so I recently just replaced my cam sensor about 2 weeks ago and just replaced my map sensor yesterday due to a p0237 vag com code. The main problem my gti mkiv 1.8t has is its hard to start, never turns on after the first crank takes about two to three cranks for the...

    My CEL comes on every few days and goes off a day later. throws p0507 code IAC reading higher air then normal. Also throws code for catalyst threshold lower then expected but thats due to the other problem i assume. I can feel a small loss of power, fuel milage went down a tad, i get a small...
  7. MKVI GTI
    I've been trying to figure out why my car is been so sluggish even after APR Stage 1. It worked great for one day and then stopped! When it worked, the car would accelerate with ease and very little pressure on the throttle. Also the throttle response was quick and precise. Now in order to...
  8. MKV GTI
    Bought a injen short ram intake last night for my 09 gti. Everything went ok other than an extra hose where the stock intake started and the sensor wasnt long enough to bolt onto the intake. Does this mean its a FSI intake? Or can something be done to get my 160$ worth?? Bought it off craigslist...
  9. MKIV GTI
    Woo! Just replaced my speed/impulse/crankshaft-positioning sensor and I haven't encountered a problem yet! Super happy for my 3rd time in an engine bay ;D Anyways, what speed does your mkiv idle? I'm at 750rpm right now, and I could've sworn I used to be at 800rpm before I needed to replace my...
  10. MKIV GTI
    Now, I'm wondering if anybody on here as actually changed [or seen] their own speed sensor? and if so, is this what it looks like? And does anybody have any experience with these sensors failing? Or know a way that I can test if this is the problem before I vagcom? I hope this thread isn't...
  11. MKIV GTI
    I've been getting these three codes when I plug in the diagnostic checker; VAF, MAF, and Fuel Air Metering. My VW is hesitating and sputters, it also likes to completely shut off every once in a while as I'm coming to a stop or stopped at a light. A year ago I put in a new MAF sensor meter...
  12. MKIV GTI
    I've noticed a fair amount of fluid emitting from what I am told is a steering sensor in the front right corner of my engine bay. It protrudes upward next to the SAI and behind the passenger headlight assembly. Any idea on what this sensor is and why is it not on most other models of mk4's? i...
  13. 2.0T FSI / TSI Engines
    So... ive got about 52,000km on my fast. Apart from other typical malfunctions (A/C, runner control motor...) there is a reoccuring one: engine coolant temp sensor. Now i had it replaced at the same time as the intake manifold runner control motor at my local VW dealership for a ton of money...
