Not too much activity around these parts anymore it seems! Here is my shiny new hazard light button. Ignore the dust :s

Did a 6 month oil change this week.

LiquiMoly TopTec was on clearance at SuperCheap a while back so I got some of that. I'm hoping it will not burn off as quick as the Castrol oil does. I used 2 litres in 6 months, 9,500km.

Also decided to try an intake clean too.
Well the smoke and high revs was a bit of fun but it killed the spark plug on cyl 2. Not really impressed by this. At least spark plugs have come down in price. Now only $14 each, were $30+ last year. Repco still wants $35 each after Autoclub discount however

I changed just the 1 plug and all was good for 300km until the misfire returned. So I went and got 3 more plugs and changed them out.
That is when I saw the connector to the coil pack on cyl 2 was not quite seated. VCDS scan showed
004952 - Cylinder 2 Ignition Circuit P1358 - 004 - Open Circuit - Intermittent
I should have scanned first

All 4 coil connectors have broken clips so I have introduced 2 screws to hold the connector rail in place.

So let that be a warning, if you do an intake clean with a spray be prepared for spark plug failure, maybe put in some old ones during the cleaning process.

I can't see on Tapatalk but what car do you have?

What LiquiMoly TopTec you using? 5w30 or 5w40?

1L every 5,000km (or close enough) doesn't sound too bad to me these days! lol. I've switched to 5W40 to reduce the oil consumption, still consumes but less than 5W30. My 5W40 is still VW 502/505 spec.

What spark plug you using?

And what is this intake clean method are you referring to? If it damages your plugs, you may as well do it when you're going to replace them.

My mechanic threw out my 15k old spark plugs at the 120k major service

The worst part was I asked him to change the plugs at the 105k service (as I was getting the timing belt replaced at 105k) but he didn't check the log book or his records so changed them again at 120k. I was less than impressed as he did both services.

Where can I find instructions on the intake clean?

Try 5w40 if you wish to reduce oil consumption, 502/505 is still approved.

Learning a fair bit about the MK5 GTI and doing the work myself.

Received advice from GFB.com.au regarding the diverter valve. The original was a better design than the revision D, though the rubber splits on the original. Pulled the original out and replaced with the GFB modified diverter - WOW! Massive difference to the lag and way more responsive. Just have to replace the brake booster with check valve (another common fault) so that the PO171 code is fixed (system bank too lean).
