Legend, i had given up on fixing my rough cold start but im going to give it another go. I suspect the temp sensors now

Did you ever sort it? Corrado 16v same problem. I’m thinking warm up regulator. Done loads over the years and never sorted it.

@@h930hec no I’ve not really looked into it, It’ll start but I have to leave it ticking over until it gets warm. If I try to give it throttle too early it stalls and won’t restart unless left for a few hours (I’m guessing it floods) …

Right now my '89 16V won't start. There's fuel and there's spark, resistance at temp sensor is 1Kohm (at 20°c room temp), ISV inner resistance is roughly 4Kohm but there's no voltage at the ISV connector. ISV is clean and works when supplied voltage. Does this point to a bad control module?

Oh yes!! crispy this is what you call a proper car!! They come with problems though but are real fun when they go okay👌 have you acquired this motor ?? Brillant video yet again really interesting 😉👍

Nice Where u located I need check mine,having bad start.sometimes take me 30 min to start

why is everyone throwing away this injector? and switch to electronic injection?? what is the cause of kj ejection??

Perfect diag! what was the name of the sensor you replaced? I cant find it anywhere - Same problem on my mk2 16v Scirocco hard to start poor idle. The blade is broken off the sensor.

Thanks Dusty! It's one of the coolant temp sender's from memory both might be the same spec but I'll plan to look over the weekend and try to find the part number or something

I'm getting a reading of 8.1 ohms for the idle control valve, ive just fitted a new one. Is this within spec. Also when I tested the coolant temp sensor resistance I'm getting 0.89, does that sound correct? I've got a very rough lumpy idle and won't run smooth until warm

Hi Kev, the Idle valve resistance is about right but the temp resistance sounds very low if that's ohms and not kilo ohm's, off top of head I'd expect (and might have in the video values) 9K cold and 300'ish hot If that's 0.89 K ohms /890 ohms should be a fairly warm coolant , could be the cause of cold idle issue Good luck 👍

I have the same enjin. Jetta Cli A2 16 valve kjetronic. My car also dont want to start when its cold. It just happened over night. I suspected the cold start. My car have been running without the plug for a long time also and this is also bit troubling

Hi, I just found your vid. I have a 1992 Corrado SLC with a severe fluctuating idle issue. Sometimes it will, idle fine, but most of the time it idles all over the place. Down to 900 up to 2500, down to 1500 up to 2000, then down to 1200 and so on. Also when you turn on the heat or air, the idle jumps up as well. Its at the shop now here in Chicago, and they just ordered a new (aftermarket)ISV valve. Any information or insight would be much appreciated. Thanks, Stu

Hey Stu, cool car BTW!! Yes ask to keep the original ISV, So as a pure guess your valve might be sticking, the temp sensor as ours was/wiring to it as it keeps changing Or even possible an air leak that's randomly opening and closing changing the idle Always make sure the body earth good and rust free! Thanks for watching Chris P

Hitya mate, whats the part number for those temp senders on teh engine (for the ISV)

I'll update the description with a link to the sender on UK Ebay, but the one I used was OEM# 049 919 501 seems to cover most of the temps senders in this era! ebay.us/XMom3b is the item/ seller I got it off Thanks for watching, I'll take a look at your channel over the weekend, Do love a great mk2 👍

Hi, I had to dig out wiring diagram and hopefully the same (as they do change stuff every so often) brown/white seems to earth on the block, and black (12v) should go to fuse 18, either one of the those isn't right, and bit more complicated to explain in text, earth missing from the engine can be common when rust in on the earth points or they've came off

Caution checking fuel systems, but 1st if be checking fuel pumps are working likely 1 in tank and other next to rear beam mounted to body. Are they vibrating and making noise when starting? If not voltage going to the connections? if power there possibly the pump not spinning . Everything working it will feed the motor. Controlled by relay & has a fuse Info should be same as 1.8 16V Hope that helps
