Mk5 General Area / Re: Intake Manifold Runner Control Error P3137 - Will my engine go boom?

Nope, no danger of wrecking the engine.  Default position in the event of runner flap motor failure is flaps fully open. If the flaps were stuck closed you would know about it as you'd have no power past 2000rpm.

Try a basic settings/adaptation in VCDS for the flappy flappers a few times and check you get "OK".  If no OK, the motor is buggered. When doing that test, you should see the motor actuator arm moving.

10 days to go flat isn't bad tbh.  If it went flat in 3 days then you definitely have a duff battery or an alternator charging issue. If the battery measures more than 12V with the car gone to sleep, I wouldn't waste money on a battery.

All looks good - but you will have to be careful, from what I read online upgrading turbo without injectors can lead to running too lean which is dangerous for the engine. Make sure the tuner is aware you are on stock injectors and you are limited. Perhaps 300hp is too optimistic without the fuel related mods?

Also the video you posted is private so I can't check it out.

It's all good in the hood. Just pull the N75 plug and you'll be restricted to 8 psi of boost and then fit the K04 injectors at the mapping place before the remap.  Probably makes more sense to fit the K04 injectors at home though and save on labour costs, but either way, it's drivable on K03 or K04 squirters before the mapping.

The main issue is whether or not the mapper can work around the rail pressure sensor.  Some insist on using the K04 sensor, and some can rescale the K03 sensor.

Mk5 General Area / Re: 62% insurance increase anyone?

Yeah the insurance on my 330d went from £665 last year to £1250 this year  Mental.

Cheapest quote on Go F'ck yourself was £800 through a no name broker with virtually no cover 

Car parts and labour costs have increased is their excuse. So what. My skills at work have improved in the last year, that doesn't mean I can demand a 62% pay rise! Greedy forkers.

The whole point of insurance is we all pay into a contingency pot to cover life's unexpected events, so what the fook are they doing with all that money?  Oh the world has changed slightly, boo hoo, 9848% more cash from you please. Utter runts, grrrrrrr.

Cheers, safe to say a turbo upgrade is off the map.

Also, genuine question, since my turbo is pretty much done for, would a bigger turbo be an easy upgrade, or am i gonna have to replace injectors and so on?

As someone who's done it on the 1.4 122hp CAXA, I'd advise against it. I've installed the turbocharger off of a CAVD (160hp), no cat downpipe, full 63mm exhaust, front mount intercooler kit, watercooled-intercooler block-off, r8 coils mod, ngk 1 step colder plugs and probably a few minor things I'm forgetting. The car was able to achieve 240hp on 100 octane and a little over 320nm torque.

It's fun for a while but you get bored of it fast. If you want fun, the 1.4 is not it. There's no replacement for displacement. You'll be spending upwards of 6k to make your car go faster than a stock GTI, who then can get a remap for $400 and beat you anyway. It's a small engine with a lack of low-down power.

Plus, you, on the BLG, should be able to just get a remap and get 200-210hp, so is it really worth investing all that money for 30 extra? Get a GTI, you wont regret it if you want fun, you will regret it if you want fuel economy..


TLDR: Fix your turbo rather than upgrade, not worth the investment.

The tapping is only audible when revving the engine up to 2k rpm, you dont hear it on deccel. I managed to replace the oil pump and rod bearings, noise isnt gone, and another problem popped up, the car starts perfectly fine the first time, then, if you shut it off, it wont start for a minute or so, after which it will start again, any idea whats causing that?

Aight time for an update!

I've taken off the old K03 turbo and I'm getting ready to mount the K04. Here's a video of the play in both turbines. The K03 has a lot of play in every direction, the 04 only has some sideways play. The 2 mechanics I spoke to said this is normal for it's mileage and as long as there's no back and forth play or damage on the walls/blades, it's good. Worst case scenario I'll just take it off again and get it repaired.

Good update, this is also a useful post for anyone who's doubting the health of their own turbos so they can compare to yours.

Less and less insurers here in Ireland want to insure the poor vRS, as it's now 18 years old. According to most of them anything over 10 years old is a death trap 

The ones that still offer to insure it have put up their prices, I assume due to the age of the car rather than other statistics.

You'll just have to shop around for a better quote.

Usually bigger turbos means bigger injectors, plus necessary supporting mods such as intercooler, high pressure fuel pump upgrades etc. Otherwise you will gain little power over the stock turbo. So you have to factor the cost of everything in.

I would say unless you've got money to burn you should just get your current turbo remanufactured/refurbished.

Why do you want to replace the oil pump if it's giving you good pressure numbers? In the 2.0TFSI the oil pump's balance shaft can become worn and loose and create an internal leak, but it's pretty obvious as it can be wiggled around. Just check nothing mechanical feels loose in the pump and there's no major scratching in the pump mechanism and it should be fine.

Rod bearings are worth replacing if they're obviously knocking, which is much louder on decel. Does your knocking get louder on decel? And they're also worth replacing if the engine has a history of low oil pressure, just for safety. I replaced my rod bearings as I got low oil pressure and there was evidence the previous owner did too. I replaced mine without taking the head off, by just pushing the pistons up from the bottom.
