Tiguan :: Boost Gauge / Vacuum While Driving On The Freeway
I recently installed a boost gauge on my 2010 Tiguan (Auto, 4 Motion) and was rather surprised by the readings when driving on the freeway.
At around 65-70 MPH on a flat surface, the manifold pressure is just about 0 (range of 1in Hg - 1psi) all the time. I am used to my 1.8t thats runs 10 in hg vacuum at highway speeds. I just find it a little odd that the turbo is working hard enough to relieve the intake of all vacuum, and sometimes even boost while driving with hardly any engine load.
My gauge reads 20 vacuum at idle and 15-18lbs max boost with apr software. What readings does every else here see? Any difference between auto and manual?
Prius (2010-12) Fuel :: Boost In Car Power With AC Turned Off
I've just automatically left my AC on the past month I've had my 2010 Prius. I turned it off this morning and was surprised at the obvious boost in the car's power. It still ran in the ECO range, but with lots more zoom. Now that the warm weather is leaving the SF Bay Area, I might get used to leaving the AC off! My last 2 MPG's were 50.0 and 45.9 I'm hoping to see an increase w/o the AC on all the time.

Up until this morning I thought I had almost a perfect car with a potential of lasting for 10 years but this morning, while I was driving on a local road with 35-40mph, so suddenly my car stopped moving and I couldn't even pull over as it completely stopped with no error or any warning/alerts! So, I turned it off and on again, it started working but I was still nervous if it would happen to me again while driving on a freeway but it didn't and I have made to work safely.
Now a question is should I bring it to the dealer today and have them run their diagnostics on their computer to see if anything is wrong with the car engine/ battery/ or anything else or should I just reboot it like we do for computers and go on everytime it happens? It's just little scary to think of its happening during a busy highway driving! I have driven it since July and has about 14K and I have had a good MPG of anywhere between 50 to 60.

GTI 337/20th Anniversary :: Boost Lost - Limp Mode?
Was driving the other day and one of the couplers came loos and I lost boost and went into limp mode. I pulled over, got it reattached, and after that it would only hit 10 lbs. i have a KO4-001 with the GIAC file and it usually hits 20+ and holds 20 lbs. I have a regular code reader and I had a code for the EBC, cleared it, rechecked the hoses, and verified with the flash loader that I was on the correct file, but it is still only hitting 10 lbs. What else I should check.
View 1 RepliesGTI 337/20th Anniversary :: Randomly Lost Acceleration - Misfire When Hit Over Boost
Ive been having two issues with my GLI lately, last week while driving on the parkway my car just randomly lost acceleration, no lights came on but the gas peddle was unresponsive. I was able to restart it while coasting and thought nothing of it. Then it kept doing it. It was raining that night but ive never had an issue before. Other times it dies it is sunny out. The second issue is sometimes when I hit over 10lbs of boost the car will start to misfire and run like crap. No CEL's come on the dash but if we scan it with VAGCOM it says theres misfires happening, obviously. Already did a smoke test and there are no vacuum leaks.

View 10 RepliesPassat (B6) :: Boost Lost Anytime The Car Was Pulling A Steep Hill Or High Acceleration
I own a 2006 B6 and I'm just ticking down the list of common repairs... The last series started with boost lost anytime the car was pulling a steep hill or high acceleration. Eventually I lost boost altogether. I replaced the PCV valve and got back a little power but still no boost. This last weekend I replaced the DV valve. The old one was visually shot. The new one is the latest revision of that valve. Now, the boost will kick in, and cut out, kick in, cut out, in a rapid cycle during any acceleration. I double checked that it was installed and tightened (stripped the bolt heads) and reseated the electrical connection. I'm still getting the rough on/off of the turbo. If I slowly increase the acceleration it will act better, but that isn't a sure thing. I love the car, but I'm about to reach the point of pushing it off a cliff.
View 3 RepliesLexus RX 2010-15 :: RX350 Push Button Start - Key Lost Somewhere Inside The Vehicle
I am very puzzled with my new 2015 Lexus RX 350 , I parked my car at the gas station and suddenly noticed that I dont have my key on me and couldnt find it inside the car anywhere. I thought I dropped it somewhere outside but to my surprise when I tried starting my car it started fine assuming the key was some where close by.
I tried stepping out and to lock the car and got a message the key is inside the vehicle so car wont lock. I was able to start the car and drive it home about an hour drive car never complained about key not detected message. I called the dealership and they told me car will keep running if you drop the key outside while the car is running but after 15 mins of driving it will give a message key not detected.
I am locking the car now using the second remote but its risky to have the car in such a condition as any one can drive it away if they open the lock somehow. I have looked every where under the seat, in between the centre console and seat, under the seats key no where to be found. Could it be possible that key was dropped outside and the car is malfunctioning that its allowing me to start it and drive it without complaining.

View 12 RepliesFord 6.7L Power Stroke Diesel :: 2011 - Motor Backfire Through Intake - All Boost Lost
Under light acceleration without any load. The motor backfired through the intake. Lost all boost. Other than the backfire noise the motor seems to be fine except for lack of power due to no boost. The motor has been serviced by Ford Dealer since new. All services have been done at 5K mile intervals. The last service was done at 60K miles. All filters had been changed at that time (oil, air and fuel).
I do have experience with turbo/ supercharged motors. My experience would tell me that the problem was with a lean condition at the time of the backfire. Plenty of fuel in the tank and no low fuel pressure warning. I have seen low fuel pressure warning in the past but it happened during the winter when temps were negative 40 degrees. The truck is still under extended warranty so I really don't have concerns regarding repair costs.
