Documentation index A Solenoid Tutorial. You can not drive a solenoid directly from your Arduino. It requires more current than you can provide and produces destructive voltages when it is switched off. There is a simple solution. Solenoids take a lot of power The solenoid I was testing with is a 12 volt solenoid the size of my thumb. It passes 1 amp of current when turned on and becomes uncomfortably warm to hold if left on. Your Arduino can only pass about 40mA from a pin. You probably will need to measure your solenoid before you can choose components. Use your ammeter to measure the solenoid’s current draw when you power it directly from the power supply.

Since that incidence, it idles at rpm upon cold start at P and fluctuates between rpm and rpm after it warms up a little bit still in Park. When braking, it takes more effort and brake feels stiffer as if it lacks some break boost. All these symptoms come and go together except for the fluctuating idle upon cold start, which is persistent.

Our Trusted Partner To our knowledge, the only production Audi Quattro that came from the factory with an all-alloy engine was the Sport Quattro. A total of of the Sport Quattros were built, with of those going to customers. These all-alloy engines were also subject to recall and most were replaced with cast iron block units, due to issues with oil consumption.

Letter to the Editor I am looking for a V6 engine for my VW Passat, must be from a five-speed car, complete with harness, control module, mass airflow sensor and possibly an exhaust. Please provide price and availability. I drive a Audi 2. I am looking for a little more power and I am considering an upgrade to the five-valve engine.

VNT turbo actuator testing and replacement – mk5-mk6 TDI engine

Thanks to Bret at RallyGrafix. The actual removal of the transmission was easy. Big bolts on the axles, easy motor mounts, lots of big bolts all around the tranny instead of those 10mm head bolts from the Rabbit that hold the sheet metal cover to the transmission to keep water out The pain was the hours we had to spend on the top of the engine trying to figure out how to remove all the crap. Transmission goes to Fast Addiction tonight 11pm to start its journey towards enlightenment e.

The issue I did have with the removal is the bolt that holds the back of the dog bone to the subframe snapped off I just barely started to turn it with very little force.

VNT turbo actuator testing and replacement – mk5-mk6 TDI engine

So we get the engine in the car and it runs, obviously very excited at this point, this whole thing has taken probably 8 months or so thus far. The car is running badly with the ECU that the engine came with, so my guys who fitted the engine Northways in Reading had a spare stock ECU lying around and i used that to drive the car up to Fearnsport. It’s only boosting to 0. They have the car there for quite a while, trying different maps and not being able to get rid of an overboost issue.

Good advice from Herman there! The trouble is I’m living in France at the moment and my french isn’t really up to deep discussions about sensors and fault codes Never mind the bloke was very helpfull even tho he doesn’t speak the queens,we connected it up and he muttered and pointed to all the small bore hoses between the turbo and the valve behind the header tank and everywhere else come to that.

He disapeared and came back with a roll of hose and sent me on my way! So I’ve replaced all the ones I can get at with the hose available. The ones I haven’t replaced I have checked by sucking the bloody things and sticking my tongue over the end to make sure they hold the vacuum. Right ,up the road and you guessed it, no bleedin difference!!! Back to the dealers and he seemed to be trying to tell me the next step was trying a load of new bits.

Not really what I want to do, can the diagnostic machine not pinpoint what part is faulty? If you changed all the hoses and kept them all about the same length you can eliminate them as the problem. I’m trying to second guess from a computer! Sorry mate but I think you have to choose between gambling that changing the n75 valve will solve your problem or finding an intepreter to get a proper understanding of what vagcom check is revealing. I’d hate to see you chucking money in the wrong direction, been there, done it!!.

I am not the owner of the following content!!!! This post is available and shared with special thanks to www. The wastegate itself is normally closed allowing exhaust gases to spin the turbo. When the wastegate actuator opens the wastegate, exhaust gases are diverted away from the turbo. This is necessary as excessive boost would result in engine damage. If the N75 fails to open the wastegate actuator the ECU triggers ‘safe mode’ limiting fuelling levels resulting in power loss.

Always check the wastegate actuator and MAP sensor if you suspect a faulty N75 valve. It is important to appreciate that how it all looks and works will depend on the engine code, as there are different turbos and valves in use.

Repeated attempts are made to stop the leaking by replacing multiple gaskets and seals. Before you go through the repair costs of having these seals and gaskets replaced, Blauparts would like to bring to your attention a prominent issue with the Audi A4 crankcase breather hose system. Many Audi A4’s have a rough service history. We consider ‘rough’ to be irregular oil changes, extreme hot or cold climates, a lot of short driving distances where full engine temperature is never reached, and excessive low RPM city driving.

This produces a great deal of condensation and moisture to form within the engine, causing a build up of sludge. Many owners have bought an Audi A4 without knowing the oil change and driving history. If you own or have just bought an Audi A4 with over a , miles that has oil leaks, the crankcase breather system should be treated as suspect. If you remove the valve cover and see a lot of resinous accumulation in the valve train area, this indicates that the vehicle already has heavy amounts of oil sludge build up throughout the engine.

Suspect number one is the Audi A4 crankcase breather system. Years of rough service history as mentioned above, cause contamination to take place inside the engine which clogs the Audi A4 crankcase breather hose system.

Audi A4 Breather Hoses – Audi A4 Crankcase Breather Hoses

I replaced the spark plugs and it worked a little, but it continues to do it. When I get on it at WOT under full boost, around rpms, the car loses all torque, misfires spits and sputters throughout the rpm range until about rpms then it all of a sudden has torque and pulls great. I don’t have any boost leaks that I know of along with vaccum leaks.

Ovlov told me about this one that he’s using: The connector for the solenoid is the same one found on most GM windshield washer reservoir and coolant reservoir tanks. It should look like this: I spliced into the power wire for my windshield wiper motor cause it was really close to my solenoid. You also need to wire in the “1N ” diode between the two wires at the plug, connecting them.

Boris suggested this to filter out voltage spikes and save some parts from ‘sploding. Cathode bar goes to the positive: I then mounted the solenoid to the strut tower and plumbed it up.

The vacuum lines or solenoid which control vacuum to the actuator can also cause turbo issues because the actuator will not function correctly without correct vacuum response. If the car’s computer sees incorrect response, it goes into limp mode to prevent any engine damage from turbo overboosting or severe underboosting. This article is written for the vacuum operated actuators but the same problems could occur with the electronic actuators.

If you take the car to the dealer, they will always replace the entire turbo because they make more money and it fixes any internal problems that may also be present. Before replacing the entire turbo, it’s worth isolating the issue to the vacuum or actuator which are cheap fixes vs. Before you do anything, carefully check and test or replace all vacuum lines and check engine error codes, if present. Do not adjust the actuator unless the car is having issues because if it’s maladjusted, it will not increase power or fuel economy, only mess up turbo response.
