Fuel leak, 1.6FSI
- Thread starter Deerfoot
- Start date
Many thanks Mike, would I be able to detect a leak from there?
Another update....long.
OK,
I`m just thawing out.
The fuel pump was tight. It`s a new (ish) item by the looks of it.
Anyway, the fuel smell was primarily from the offside so I began squeezing my hands down below the wiper motor as far as I could trying to feel for moisture. The air intake pipe was fouling my chubby hands so I grabbed some pliers, loosened the spring clip and removed the pipe from the engine end.
This allowed a bit more room for exploration.
Now, if you follow the pipe from the filter assy mounted on the offside suspension tower there`s a pipe that goes to what I presume is a pressure relief valve (it had 3 bar stamped on it). One of the pipes that emerges from the valve is a kind of S shape and it attaches to a bronze coloured nipple on the offside of the intake manifold.
This pipe was loose, so loose in fact that as soon as I touched it it came off and fuel started haemorrhaging at quite an alarming rate at the intake end. I quickly put my hand over the air intake to kill the engine.
On examination, the end of the pipe was very worn. I got a scalpel and cut off around 15mm of pipe. Using a pair of long snipe nose pliers I managed to get the spring clip a couple of cm down the pipe and eventually (after some choice words!) managed to get the pipe back on the nipple and the spring clip on as good as I could.
A quick rebuild later and everything appears to be OK. There`s still an alarming amount of fuel around the place so hopefully that will evapourate overnight.
I sat in the car with the screen demist on for a good ten minutes and apart from the clothes I was wearing stinking of petrol (superplus, annoyingly) I think I might have cracked it!
I`ll update tomorrow evening.
Mike, another huge thank-you for your pointers, are you sure you don`t want to move down to Wiltshire or Hampshire for a while?

Yep, that`s the one, although the diagram looks like it`s reversed unless it`s looking forward?
The spring clip (item 12) is where it detached.
If I could be so bold to ask for the part number I`ll order one tomorrow and fit correctly at the weekend.
Mike, once again, I`m in your debt!
I ordered a new pipe from Heritage Audi in Salisbury this morning. Of course they didn`t have one in stock (do franchised dealers stock anything these days?) and due to the weather they couldn`t predict a delivery date.

The Audi parts network is generally pretty good - I was at Manchester Audi this morning and at 8.30am, they were still hand-balling parts that had been dropped off an hour earlier.
Good on you for getting the part though - was there any reason you could see as to why the old pipe had a damaged end?
Cheers

I think the pipe was quite badly age-hardened. The original end was visibly larger than the rest of the pipe, this was true also of the interior diameter.
I think that my car has had a fair bit if work done to it prior to me buying it (the ABS unit, fuel pump and some of the intake manifold look suspiciously clean) so I can only assume that in an ideal world the pipe should`ve been replaced during that maintenance.

Mike, you're a star!
I've been following this thread. As you know, we have a 1.6FSI as well, and we also live in Wiltshire, so this thread was of interest on two counts! (Deerfoot, we must introduce ourselves at the next club meet?).
You're a star Mike, because you never cease to amaze me on all of the knowledge you have stored in that brain of yours, and you are also always so polite, respectful of others lack of mechanical & electrical knowledge, reassuring and generally an all round top bloke!
Thanks for all that you do for fellow A2 owners. Without you the club would not be the same!

Thanks Eric - not sure what I've done to help, but if this has been of assistance to you, then you're very welcome.
It's Deerfoot that has solved his own troubles really - all I've done is point things out from a distance and provide parts assistance.
I'm sure that between folks such as Spike, Sarge and others with specialist knowledge that the forums would tick along nicely without me, not that I'm planning on leaving anytime soon!!
All the best,
Mike

I agree 100% here.
Mike, you gave me the confidence to go and have a look at my A2 for myself (even though it was dark, cold etc) and I doubt I`d have had a crack at it if I had not found this forum!
Many thanks for you assistance with this and the other threads that I`ve read. The parts catalogue picture was very helpful.
Ezza, I`ll hopefully get to a meet at some point!
Cheers, Simon
