Heating & Cooling / Temperature sensors/ senders
Last post by DomBash74 -
Hi everyone

thanks for any help to this and previous threads I have posted recently.
On my J reg Mk2 golf Driver I have 3 temp sensors/senders all on on one plastic coolant manifold bolted to the head. On top a black closest to the head then a red behind it and one underneath which has a white plug. Can anyone tell me what this is and where I can get a replacement from please? When I look online is says its related to air conditioning which my car certainly doesn't have!!

Thanks again

Dom

Hi I am currently  experiencing similar issues. I can start the car from cold fires straight away and runs perfectly. When the car warms up   I have the same issue as you. I think the fault lies with the blue temperature sender I have ordered a replacement and am awaiting its arrival so can not say if that is the issue yet. Out of interest I ordered a hella replacement as I understand other makes are thought to be unreliable.

Hi Dom,

I've recently (last weekend) had a similar issue when putting mine back together, not exactly the same, but odd things activating and interfering with others. Turned out to be an earth had worked loose off the main earthing distribution block, located near the back of the fusebox. I'd certainly check there.

Thanks Monkey i'll give that a look

Engine & Gearbox / I need help with my carb, breather pipe etc
Last post by G268SWD -
Hi all,

I posted on facebook but not having much luck getting help so I thought maybe people might be able to read through and take a bit more time to reply here? Would really appreciate if i can find someone clued up on carbs!

1989 1.3 Engine
So this saga started because it smells really bad of petrol when im driving the car, my daughter constantly complains it gives her a headache. I cant see anything obvious. Ive checked all the fuel lines and they are new-ish anyway but all secure and not split or leaking. I cannot see anything obvious around the carb but then im no expert knowing what im looking for...
The smell seems to be coming directly from the carb, its stronger smell directly over it, but then that might just be obvious as thats where the fuel goes  :))
I have a feeling its running a tad rich.
It starts perfect when cold.
It takes longer to start when its hot - could be related or something else?
It idles fine.
When you go to pull away it will sometimes kind of choke itself and splutter and you have to give it a rev to move.
When you are driving it seems to drive really well.

I was going to adjust the mixture screw, but im being thick and i need to work out what carb it is to be able to find the mixture screw....
So on the carb it says Pierberg 2E so obviously i assumed 2E however in the haynes manual it doesnt look like the picture of the 2E. It looks like the picture of the 2E3. So would the '3' also be stamped on there if it was a 2E3 or would it still say 2E regardless and it could well be the 3?
So when i know what carb it is I can work out where the mixture screw is. I have an idea BUT i have googled and it says most carbs turn clockwise to make it leaner, but the 2E turns anticlockwise to make it leaner... so again I need to know for definite what model carb it is so I dont mess up the mixture....

If anyone can tell me that would be great?

And this I think may be the mixture screw? But need to know how much to turn it and in which way.

So the next thing i noticed while i was there was there was a lot of oil build up which seemed to be coming from the crank shaft breather pipe where it joins the airbox. I wonder if this is creating to the smell being as its just above the manifold?
The pipe itself is very soft and very dirty inside so I guess it wont hurt to change it. Also I assume this yellow thing is a oil breather filter which looks ancient so it probably would be good to do that too? Is this is a bad idea and a pig of a job for any reason now is the time to tell me to leave it alone!  :D

Mk2 Golf Chat / Mystery starting issue 1.8 GTi PB- help!
Last post by jo.adam.kay -
Looking for help with an ongoing issue.
My 8v GTI digifant has an ongoing starting issue. It takes a good 5 seconds turning the engine over before it fires and then it runs really lumpy. After a little throttle for a few seconds it clears and runs great. Car pulls really well when driving. No smoke etc and gets good MPG when I’m cruising along.
Car has had a full diagnostic and tune. Plugs, rotor, cap, leads and coil all good. Recent new idle valve,  both fuel pumps have been replaced and prime as you would expect.
Battery has full charge and volt meter is showing good volts when running. Throttle body switches are working and lots of the connectors have been cleaned. No vacuum leaks. Blue temp sensor tested.
Injectors have been tested and are in great condition.
It occasionally starts fine, usually in the morning. When it’s been to the garage to check for known faults, with no solution found, it starts fine for a couple of days then the problem returns. If I restart the engine within a couple of minutes of turning it off it works fine.
Engine was rebuilt last year by previous owner and has run fine until now.
Good oil pressure on start up. In the recent hot weather with oil temp at 130c oil pressure at idle can drop to an indicated .6 bar but no oil pressure warnings on dash.
My local specialist who knows these engines very well is now expecting an electrical issue.
But I would love some input from other MK2 owners.  Thanks in advance for any suggestions

Mk2 Golf Chat / door lock passenger side
Last post by mintysgt -
ok so this weekend, my jetta door lock decided to duck me off and fail "drivers side" after fitting new locks and waiting on heritage for over 7 months. lasted all of 3 weeks grrrr. But even the old lock and new lock, including on my golf, the passenger side lock only locks the door and doesn't unlock with the key. if it had i could of just opened it that side and reached across etc

now my question is, how do i remedy this, this cant be right surely and correct??

all the mech appears free and work correctly with the handle off the car
