#578260 Clutch & Dealing with VW cust Service

Posted by shawng on 25 November 2020 - 01:35 PM

The only thing we have ever seen be covered is the dual mass flywheel that is prone to failure. There was one report here of the clutch grenading and taking out other bits, but I can't recall if it was under warranty to begin with. the reason they are telling you that there will be a cost to investigate is to cover them should the failure be your fault. One would hope that if it is a warranty failure, then you will end up paying nothing. I think itis smart of them to prepare you for the worst case, rather than pull the transmission and then surprise you with a steep bill.

#578018 Turbo oil leak.

Posted by shawng on 19 November 2020 - 07:16 PM

Depends on how bad the leak is. The return is not under pressure, but if it leaks onto something hot like the manifold, then a fire can occur. If the leak is bad and you don't check your oil, you risk a low oil issue.

#577808 Heater Core abs Coolant Tube Woes

Posted by shawng on 13 November 2020 - 10:58 PM

So it looks like MQB is where they started adding a bag of SILICATE, not silica. And that makes more sense, as silicate is an additive in coolant. It’s amazing how many of the posts say silica. Next MQB we get in, I will take a look and report back. I can see how a bag breaking will cause issues. But for the heater core issue in this topic, this is all pre MQB and not the case. And all th ones we have seen have OE or OE-equivalent coolant, with no mixing of foreign product.

#577764 Heater Core abs Coolant Tube Woes

All to familiar with galvanic corrosion. When we first set up the shop, we used copper tubing for air lines. The main air filter we had was made from aluminum. It quickly turned to jelly on the inside. Moisture in the lines wa the electrolyte, but what made it even worse was that at one spot in the shop, the air line crossed over (within 6") of power lines to the main breaker panel. I was able to measure an induced voltage well over 1V. After adding many grounds, it slowed down the process but never cured it. Now we have the professional internally coated tubing and all is well.

We have seen this before and have changed several heater cores. If you are not careful, the tubes can indeed be damaged. There are no special tools needed, but in order to change the tubes the whole HVAC box needs to come out as the tubes run behind it, and in order to remove it the WHOLE dash has to be removed. Before beginning, you should also get the plastic fitting that go between the rubber hosed and these tube in the engine bay. They are a quick connect and will definitely leak once removed for the fix. they are not too expensive.

On the Tigs, it looks like there were several years where the heater cores will plug up over time, causing first no heat on the passenger side, then no heat at all. Rumor has it, the core is at fault (incompatible materials used), causing the coolant to crystalize. We cut mine open to look and it was nasty.

#577470 Lubricant for pads and sliders

Posted by shawng on 03 November 2020 - 03:47 PM

We use Permatex purple on the metal contact points and orange around the boots/sliders (because it is better with rubber).

Saving a dollar on a brake job is like reusing a tea bag. Please don't cheap out on one of the components that keeps you from dying. Just remember you only get to not stop once!

#577416 Weird clutch problem..

Posted by shawng on 01 November 2020 - 05:41 PM

We had to change the clutch master cylinder in a Golf R that stuck the very same way. Who'd of figured that making it out of plastic was an issue? Very common on the R.

Straight across the battery! Also turn off everything on the dash. Radio, HVAC

#577352 Turbo Wear

Posted by shawng on 30 October 2020 - 02:40 PM

Another item to note for those of us that experience colder winters, is to let the turbo warm up a bit before getting busy. Cold thick oil is even harder on the tiny bearing in the turbo than the mains on the crank, and when cold, oil pressure is quite high which is a bit harder on the seals.

#577090 rear brake pad change

Posted by shawng on 22 October 2020 - 04:06 PM

Welcome to the forum. 


A booster pack will be fine as long as it can keep the voltage at or above 12.5ish. turn off the HVAC, radio and anything else that comes on and you should be fine. The car only has to be 'key on' when you are using VCDS to open the caliper and then when you recalibrate at the end. While you are doing the mechanical stuff turn the key off.


And whatever you do, DO NOT key on when the calipers are off the car. Some VWs will reactivate the parking brake with a key on and that will destroy it.

#577086 2.0 TSI oil leak?

Posted by shawng on 22 October 2020 - 03:46 PM

Welcome to the forum. 


My thoughts, well I think they are fishing. the oil pump is internal and if it leaked, it would not be to the outside of the engine. And an O2 sensor will not cause a leak. Finding a leak is tough sometimes, but the first step is to shampoo the engine really well and then run it. If it's not obvious then a fluorescent dye can be added to the oil, and then you would drive around for a bit and then check again.


To be clear, if the oil pump was failing, you would have a low oil pressure light on the dash and/or engine failure. The TSI can live for about 15 second with no oil pressure, running. And a failed O2 sensor would cause a CEL that would need to be diagnosed.

Let’s move on please. circling back two months later over who said what and who got offended is in poor taste.

#577022 2009 Headlamp Ballast Replacement

Posted by shawng on 20 October 2020 - 12:16 PM

On the 09, you can remove the cover part that spans from lamp to lamp, then remove the grill and the lamp assembly lower bolts will be accessible. But before that, do as Stiguan stated and test the bulb. On an HID, you can't readily look at it and say it's good. Next step would be to scan the car with a capable scan tool like VCDS. If the Ballast is bad, there might be a DTC. Then, you can proceed to disassemble the car. is an independent Volkswagen enthusiast website owned and operated by VerticalScope Inc.
