Hi, <p> Last few days I noticed a strong gas smell soon after I started cold engine. I could stay for a minute or so. I can hear it around the engine, not behind the car...<br> I don't have anything yet to say but I was wondering if is sounds familiar? <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/confused.gif" BORDER="0"> <p>Thanks<br>Kirill

Re: Strong Gas Smell After Cold Start -any input? (Papa_Kirlo)

I've had the smell of gas before after a cold start, but it didn't seem strong to me. I came to the conclusion that the exhaust fumes were still quite gassy (excuse the wording) and the smell was entering the cabin through a slightly open rear window. <p>I did have a strong smell with my Mercedes, and it was becuause small droplets of gas were speaping out of the cylinder heads - or something to that extent. My mechanic told me and I probably twisted the words around. <p>I hope there hasn't been any performance issues since the smell. How's the weather back in MA?

If your O2 sensor(s) are going they will make the car run very rich and you can have a fuel smell

Re: Strong Gas Smell After Cold Start -any input? (JRL)

JRL.<p>Thanks. I'll try to check if any errors logged with OBDII (no CEL so far). Didn't notice the mileage decrease yet. On another hand in last few weeks I felt like the car was not perfomed really well, like if you removed modded ECU and return back to stock. I have to look into it. Is there any way to test O2 sensors? <p>Cabot, hi <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0"> <p>It's warm lately here. Not Cali but still OK with me (I'm not skier). How is your story goes about car delivery issues? Hope you solved it.. <p>Cheers. Anybody else???

My car woes are getting better. Allied sent cosmetic appraisers for the paint damage and are going to fix damaged areas. As far as the wheel noise, I never got a call back from Galpin Volvo and USC has been amazingly busy. Homesickness has also hit me. I really miss Massachusetts. 128 feels like a dream compared to some roads here. Sorry to hijack part of your post!<p>About your 02 sensors, there must be a way to test them. You could have the dealer check the computer. My S/E/W panel logged 200 faults once, but never initiated the CEL. I hope you solve the problem!

Also doesn't hurt to look at the seals on and around the fuel injectors. It's a common sticky-spot for these cars.<p>It's also a quick and easy fix if you do have leaks. Seen this in at least 4 T5s over the past year or so.<p>Cheers,<br>Prospero

Prospero,<p> Thanks <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0"> Good call. <br> What do you think about send injectors for service? Like new seals, filters and recalibration? Cost about $150 per set..

Re: Strong Gas Smell After Cold Start -any input? (Papa_Kirlo)

I bought all new injectors for less than $200. (440cc Ford Racing injectors.)<p>If it were me, I would buy the seal kit for each injector and simply re-seal them. If you're really concerned about their flow then you can always run a bunch of Techron Concentrate through the car with a low tank of gas. What's more, the injector seal kit has the rubber rings, plastic cap, and all items that you could possibly remove from the injector. (Even the spacer for the fuel rail!) So simply by re-sealing them and doing a good hand cleaning with some Berkable Gum Cutter...you'll be just fine and save a bunch of $$$.<p>Really as a point of reference...my 850 T5 had 264000 miles on the injectors with no issues...my wife has 150k+ on her S70 T5 with no issues...and my old V70 had 92k miles with no issues on the injectors. I've only re-sealed them on my C70 and 850...just since I pulled the rails off of the cars. The cleaning takes an hour but is worth it. Just remember to clean the area around the injectors before pulling the rail off. Otherwise you'll get crap right into the intake. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/wink.gif" BORDER="0"><p>Cheers,<br>Prospero<p>

Re: Strong Gas Smell After Cold Start -any input? (Prospero)

The reason why I was thinking about cleaning injectors is an annoyng clicking noise they making all the time. I hoped it goes away after the service. I remember when I bought the car 2+ years ago the engine was much quieter. Well, I know I'm paranoid about my car. <br> <br> I probably not going to touch injectors/seals soon. I've repalced the spark plugs past week-end and checked injectors visually - these weren't any wet spots or something to make me worry. On another hand I noticed some kind of leakage form the upper side of idle speed stabilizer. Here is a pic what I mean:<br> <br><IMG SRC="http://b.im.craigslist.org/nz/VD/VJAEvleLyYS9VUQMV8CJcRsAy2DX.jpg" BORDER="0"> <p>It's not mine; in my case it was not shiny, it had some very fresh wet spots around the upper flange. I wanted to tight the O-clamp but I didn't have proper tools. I cleaned it for now and will keep my eyes opened for some time.<p>

In my case...that hose clamp has been tossed and I used a typical stainless screw-type clamp.<p>Good luck with it!<br>Cheers,<br>Prospero

Papa...do you mind posting that picture again? I've been away all week with my school skiing in Killington, Vt., and missed your post...now the link for the picture is broken.
