    Hello, Firstly, I want to thank all of the veterans on this forum for all of the information you have provided. You are the true MVP's! I have been looking though a lot of posts, but nothing narrows down to exactly what I should try next. I have a 1999 1.8T AEB Passat with a high idle and...

    Hello I just bought an automatic 99 passat not to long ago and it seems to have some issues with the throttle bouncing up and down when I press a little past quarter throttle, theres no rpm reading , and very little power in drive. Here are some pics on the code it gave me and what the car looks...

    04 V6 automatic I had to remove the throttle body to replace a burst coolant hose. Will need to adapt it when I re-install it or just install hook up and go about my day? The only thing I saw in the Bentley book was it needs to be done if replaced. Thank you

    Can someone please post the diagram or list the correct steps to check wires from throttle body to ecm? I am pretty sure my throttle body is bad but want to make sure my wiring is good first. Thanks

    So I decided to change my air filter and clean my MAF. After i did that, the car was idling better and running better. Idle was 750 -800 rpms. So I decided to continue the cleaning of the intake system by cleaning my throttle body. Everything went good as far as taking it off, cleaning it...

    All, I've got a 2003 VW Passat 1.8T AWM. Last week I started to get a rough idle. I thought it was my pedal going out (and it still might be) but reading online pointed me to a vacuum leak. I started checking for cracked hoses and by just squeezing with my fingers I broke a vacuum elbow and...

    After rewiring the throttle body for the second time a few months ago, I just got another engine workshop fault and EPC and MIL indicators. Codes are for P0221 static and also P119A intermittent fuel pressure sensor malfunction. There was also a general ecm 01314 fault. I’m pretty confident that...

    Hi, Anyone know the part number for the splined O-Ring on the air charge pipe that goes from the intercooler to the throttle body? 2004 Passat AWM engine. I'm chasing a boost leak, and as I have removed & replaced this hose 2x per year since new ( 26+ times) while doing the oil changes, I...

    We have a mis-fire condition with cylinder 3. Under light throttle (cruising) the 1.8t purrs as it should. As soon as you try accelerate or pull a hill you get a mis-fire and loss of power. Only code in the computer was P0303. I'm thinking the mis-fire under load "only" is an indication of...

    I purchased a 2009 Passat less than a month ago. When I did the test drive, the warning "Check engine Service Now" came on and I was unable to accelerate above 20mph. The dealership replaced the throttle body and after about 2 weeks of having the car the same light came on (no trouble...

    I bought my 09 Passat used. When I test drove it the display showed "Service Now!" and I had the pedal to the floor and could only get up to 20mph. They replaced the throttle body and everything seemed fine. I've had it for about 10 days. Yesterday I started it and the same "Service Now!" came...

    Hello, I recently did some maintenance on my Passat, I've posted a few threads, and everything has gone well except for the TB as I suspect it may need to be realigned. It was disconnected and I did open the butterfly several times to clean it. It runs great; however, running it through gears...

    Hello Everyone! Recently we Picked up a Passat B5.5 1999 with 1.6ahl 74kw engine. Well so i got little question, is it normal if Throttle is a bit lazy? For example when u rev it it revs good, smooth but RPM are getting down slowly, or if you shifting gears, RPM's stays for 1-2 sec or a bit more...

    I searched the site for information like this and couldn't find it anywhere so here is my experiences with my Passat. It is a 2003 B5.5 station wagon (estate, combi) with V5 engine although I would assume that the same information would apply to the V6 and 1.8 if they use a similar throttle...

    Hi everyone - first post here. I'm hoping to get another 6 months or so out of my 58 plate 2.0 litre diesel Passat highline. The car needs a new throttle body. I am trying to source it as cheap as possible as the car only has a while left. However I can't find the part - I've already bought...

    got a 04 passat 1.8t and was getting a random high idle code, did not find any faulty vacuum lines but did see that the throttle was a little dirty so pulled it to clean. I have a cheap blue kkl cable and full registered VCDS-light, it will run the relearn falling to ~10% then settling at 12.5%...

    Ok still working on my new vw. A 1999 Passat v6. Bought it with bad gas and no battery. It ran with a miss and seems like it's in limp mode when driving. I bought a new throttle body when a vw guy scanned it and it still has the miss. I am wondering if it could be the main compute under the...

    I just got my head rebuilt and put my car back together and now it bogs down when I shift wants to stall when I start it and overall just lacks power. Did I possibly put the camshaft gear on backwards there was a timing mark on both sides and the head shop took it off so I'm not sure, but I also...
