I'm a newbie on here and firstly I'd like to say hi to all members. Secondly, does anyone know of a local specialist or anyone in the Wiltshire area who can help me out with my rough idling and hard starting when hot GTI.
I know a lot of what the issues can be but don't want to replace costly parts for no reason.

I ended up asking on here, reading a few other posts and sorting it myself.
What sort of issues do you have? I may be able to help. It's quite a basic system and fairly easy to work on.
I'm in Devizes by the way!

Thank you for the reply. I'm the same and I'm a mechanic myself but didn't really do much work on these when I was younger. I'm only in Lyneham. It's running dog rough and hesitating on acceleration and also the tanks holding pressure, I.e there seems to be a blocked breather or something. Your help would be greatly appreciated.

Have you tried anything yourself yet? It may just be ignition problems. Does it start and run ok when cold?
I have a tank pressure issue as well and thought I'd solved it once but it's back again! It may just be dowb to the gravity valve behind the the filler cap.

I'm just on with starting to work stuff out. It was stood for a long time but the previous owner used it has a daily drive. He has replaced a lot of stuff trying to find this fault.
It just seems to run rough all the time. I'm going to change the gravity valve because that's what I've been thinking. He has spent a lot of time replacing the fuel side even down to injectors but I'm unsure that's the issue. I've only had it a short time and I'm sure it will get fathomed out but it's also good to know people in the local area too lol.

On to the running issues, I would check the timing first and then make sure the ignition side of things are in decent order. Once you're happy with that then move on to the fuel. Common problem on these is that the filler neck rusts and water and rusty bits get into the tank and then sucked through the fuel system. This can damage the whole fuel system. Also common is vacuum leaks which includes the seal on the idle speed screw.
You might need a pressure gauge for the KJET and I used old baby bottles to check the flow on the injectors.
Your storey sounds similar to mine, previous owner replaced loads of bits to unsuccessfully cure a running issue and then left it in the garage for over 7 years! My fuel system is virtually new but it runs ok now!
Good luck and let me know if you need any help or tips!

As for spending the money to get it going, be prepared to dig deep. I reckon I spent over a grand before mine was running (but the wife thinks it was about £400 ) Definitely worth it, great fun to drive even in standard form and keeps up with a lot of modern fairly quick cars. Touch wood, mines also been very reliable and I've done a few long journeys in it now. including a trip to Luton and back last year on one of the hottest days of the year.
I can pop over and have a look at yours if you wish.

There's a small screw on the end of the accumulator, if you remove the screw and petrol comes out the accumulator is shot.
looks like this, in the second picture you can see the little screw.

I've set the timing which was out but waiting on a timing light and Gas Analyser to get it set up perfect. I've been doing all the braking system as well so it stops too. How's you? Enjoy the snow? Thanks for getting back to me.

The good old timing light, I threw mine out years ago because I didn't think I'd ever need it again and had to buy a new one when I got my GTI! I adjusted my mixture by ear, and despite critism on here my CO was almost bang on when I took it for an mot.
A tip for the rear brakes, I found that the best way to adjust them was to take the drum off and adjust it manually and put the drum back on. Keep doing this until the drum is just about touching the shoe. It's a bit of a ball ache bit it made my brakes much better.

I'm stripping them down and changing all the fitting kit as the shoes are like new but everything else isn't lol. I'm re- piping it and changing the master cylinder but the brake compensator is shot but can't find one of them anywhere.
