New Members Say Hi! / Idle problems MK1
Last post by pedrocaneira -
Greetings! I had gone through a couple shops to try to fix the unstable cold idle of my MK1 Golf Cabrio (1991), with the 1.8lt, 90HP engine.
It seemed the idle valve was the problem, I replaced it and the issue persists. A couple years ago, a technician who seemed to know a lot of the older VW Golf said he chose to leave it running well when hot and not that well while cold.
In fact, about 1:00/1:30m after starting the engine, and revving it smoothly, the Idle becomes stable and the car runs well.
Has anyone ever experienced the same issue? I believe this engine (injection) is already an MK2 gen.
Cheers, Pedro

On further reading I've figured it out. I remembered that some point this car had a mk3 starter fitted for more grunt. As such it only has one spade connector and I'll bet a beer that the csv isn't hooked up.
After being idle with old dirty fuel, it had no chance of firing without the help of the csv.
Jumping it did the trick amd got that new fuel in for a start.

I think I'll fit a proper 16v kr starter with the right dual spades and hook it all up properly.

In the mean time I'll track down and replace the faulty temperature senders to hopefully stop that blinking light.

To add, I jumped the CSV with residual fuel pressure and got it nearly going. I then jumped it fully whilst cranking and got it running pretty well after about 5 minutes. Killed the ignition and hot start was bang on.

Technical / Cold start and associated wiring
Last post by james_nich -
Hi everyone. I've finished sorting out my fuel filter / pump / housing issues and have achieved fuel pressure at the injectors / 5th injector rail.

I was having real trouble getting it running so started checking out the cold start side of things. I'm not hugely electrically minded so please bear with me! Strong battery with a strong crank just no fire.

The distributor needs some love and has been soaking most of the RHS of the engine in oil for a long time. Therefore a lot of the WUR and coolant sensors were very mucky. I went round and cleaned all of these connectors up and made sure all the earths were corrosion free. Still nothing.

I took out the CSV to see what it was upto. Loads of pressure at the banjo but nothing being sprayed on ignition. I jumped the CSV directly to the battery and it sprayed nicely.

Funnily enough I noticed that the coolant sensor was flashing on the dash. I earthed the red and black wire and the temperature gauge maxed out so that's working.

Am I right in thinking that the CSV could be dead because the sensor is knackered and it thinks the engine is hot and therefore not grounding the CSV circuit and giving me starting issues?

Thanks in advance, apologies if this is a bit rambling.

Does't look likely, but is this still going ahead?


Hi, sorry only just seen this. Not been on much lately.

Yes this still goes on every month (except January) on the first Friday.

I’ve started to push this out to more groups as a general car meet as so many of the regulars (myself included now) either no longer have a mk2 or their mk2 is off the road and they come in their daily or alternative motor.

For the first time in a very long time there was no mk2 golf, in fact not even a VW last Friday. The closest we had was my sons SEAT Leon FR, I was in my new Mini, and we had Porsche there. So VAG and a good spattering of German.

The next meet, and last one of the year will be December 5th.

We usually get a decent turnout for the December meet, with the option to go into the carvery for a dinner.
