Swiftkids Corrado VR32

[swiftkid 1]

If it were a vr6 then I would say not but I've read a lot about 60k engines, long life service intervals and stretched chains... NOT GOOD! apparently it's to do with sachs stamping their logo too deep and weakening the links.

 

Unfortunately I'm running an a3 engine which is the ultimate mongrel engine, bits of mk4/5 and audi tt. Would appreciate screen shots from anyone!

[mic_VR 3]

if i had my vcds I'd get some tonight for you. hopefully someone will read this and post something up.

 

Is it a trait of the 3.2 then? I've not heard anything specific, but then I've not really read up on the R32 motor

[Mk3highline 10]

I'd not Worry too much about th chain stretch mate at the moment as the vvt will be fixed to one setting whilst you got faults stored on the ecu

Check your earths and post the ecu with the faults to vince to clear/coded out

[Dox 22]

Vvt will be either advanced or retarded, there's no in between other than the time it takes them to move, it's controlled by solenoids on the side of the head opening and closing Feeding oil to galleries onto the vvt sprockets.

I've had another look tonight but there is absolutely no lambda adaption, I've checked over earth's and cannot find any bad ones.

 

One weird thing is that it's saying sai relay is not connected when it is so I'm going to double check that, I might try wire up the solenoid as well to see if that shuts it up and starts behaving

[Kevin Bacon 5]

Yeah I would connect the SAI solenoid and the carbon can purge valve. The engine won't grenade itself with stretched chains, don't worry about that for now.

[swiftkid 1]

The carbon canister is connected but not plumbed in (VR6 valve) so might double check wiring and make sure I've got power going to it.

 

I'll try get to wiring for SAI stuff and get it connected, got this weekend to play so fingers crossed I'll get some luck

[Mk3highline 10]

You spoke to stealth?

[swiftkid 1]

Yea, he said to send him across error codes and he will take a look. Going to try find wires for sai solenoid and get it connected and troubleshoot evap to see why that's being a git

[swiftkid 1]

Had another look tonight, found a broken wire at the n80 plug... One error code down, 2 to go. Had a look at wiring diagram and I might have wired up the sai relay... To nothing.

 

Appears one side is connected to ecu, through the relay and then it looks like it just needs an ignition live so that's my next port of call. The lambda voltages are changing but still no adaption, fingers crossed if I can lower the error code down another 1 or 2 things will start happening!

Good work 🏼

[swiftkid 1]

On a positive note, it looks like my mpg reading might... Might be working. Can't say for sure as on the way to test centre I was obviously in open loop plus trying to get the cats stinking hot it was reading 1mpg but it's better than 99.9, well actually it's not lol, but you know what I mean

[Mk3highline 10]

I've got a completely different set up but got egr and sai faults so been open loop for last few months and I'm getting up to 41mpg calculated super steady and mfa is showing a fraction more

It's going to stealth the Monday after next to get sorted I hope, before I start on blower

Just think it will be quicker once it's sorted

[swiftkid 1]

Well another error code down tonight but still no adaption, sai relay connected and that's happy now. Can the lambda start adapting on idle or does it need to be driven to start the adaption.

 

Obviously proper adaption needs it driving but just a bit of movement would be nice!

[swiftkid 1]

Well this looks better! Some lambda adaption at last!

 

Finally down to the bare minimum fault codes, next step back to MOT station.

You'll love it once the bugs have been ironed out!

[Mk3highline 10]

🏼🏼

[swiftkid 1]

And we're back in for test tomorrow, everyone cross their fingers for me please!

[Mk3highline 10]

Which fuel do you use?

Try tesco momentum for the mot as I've noticed it runs slightly leaner than v power

everything crossed mate, sure it'll be fine

[sexybourbon 0]

Good luck with it dave

[swiftkid 1]

B@stard F***ing car!!!!!! HC is now within tolerance but CO is still too high, read 0.7.

 

I'm struggling to find a reason to keep this POS now, anyone fancy a swap for a MK2 Escort?

[Jim 1]

Might be time to try find a more friendly MOT tester!! ;)

[Mk3highline 10]

It's still probably running slightly rich still you done many miles?

Pour in about 10-15% methanol it will get you through mot

[dragon green 4]

Was it properly warmed up ! Could you not give it a bit of a "thrash" right before the MOT?
